To bubble the water from the bottom to the top means that the gas needs to have enough pressure to force the water out of the tube. That's more pressure than my gassifier generates in this setup.
You should make an airtight crockpot to heat the wood inside, leading to a canister to store the gas. Something I found online: Higher temperatures improve hydrogen yield in the gaseous product while CO yield decreases. Under nitrogen atmosphere, after 2 s at 950 °C, 76% (daf) of the mass of wood is recovered as gases: CO, CO2, H2, CH4, C2H2, C2H4 and H2O. Tests performed under steam partial pressure showed that hydrogen production is slightly enhanced.
Absolutely correct! Coil condenser with a collection pot to capture contaminates at the bottom works very efficiently. I've used this method for years to convert acetone to diketene with great success.
I like how pretty much every by-product of this process is a useful material. The charcoal has lots of uses, the tar can be used to make wood rot-resistant, the wood gas is a decent fuel. There's really no waste.
@@MrRasZeein medieval times people had dedicated parts of their forest for firewood, idk how it’s called in English but in Dutch it’s called “kreupelhout”. They had fast growing trees that they kept short and guided into growing many sidebranches, these could then be harvested yearly for firewood in the winter, and then next year the tree had made new branches that could he harvested. Saved people a lot of trouble, as they where usually close to the farmstead/village and no need to end the lives of trees just to get firewood.
@@rubenskiii sounds like what I'd call a wood coppice. That method of regularly harvesting wood can result in the roots and base of the tree living for centuries!
That's so cool that you read all of the comments! I love how meticulous you are in your projects and how you're always showing where things didn't go as expected so we can learn from that too.
We had three massive gasometers in my town, a few minutes walk away from where I live, they were a sort of landmark you could see for miles. I miss them oddly enough.
Marcus Polus read again, I said your. You're right because you used your brain to realize your is the right word.. How about that there their they're word eh?
7:05 the condensation is a mixture of wood alcohol (methanol), gasoline, tar and diesel. All of them are also valuable. You can set multiple filtration setups to collect them as well.
Could actually be harvested with some water-cooling of the pipes, perhaps a spiral chamber with an outlet, then the gas passed on to the gasometer will also be purer but of course also denser, so perhaps you'd need a spring or something to lower the pressure in there, basically sucking the gas in.
Tube with in and out connection, cooled by water, so it condensates to pipe surface and collects on the bottom as a pool, witch can then be with regulated flow valve let empty to container. Separation would be using standard oil industry techniques of fractional distillation as it was mentioned, where start product is heated and released to chamber. Due lack of oxygen it wont burn, but turn into gas. Chamber has several different levels with different levels of heat. Gasoline or methanol is easiest to turn to gas and will float on top chamber, where as heavier oils that take more temperature to turn into gas will condensate on lower levels, where these can be collected to separate containers, filtered again and put on use.
I would consider 'cracking' the distillate while it's still a avpour by heating further over some kind of catalyst. That way you will get more gas from the liquid portion, so more yield of usable gas.
I don't know about anyone else, but this kind of stuff fascinates me. I can't wait to build one of my own. People like you need to be running this country. Take Care.
Silicone tubing is good to have around. It's short term temperature resistant to well over 300°C, long term to about 200. It won't melt ever, and if it starts to discolour, it's degrading or basically slowly burning up. Vinyl has a fairly high melting temperature... i forget... but it's a very hard plastic, so tubing must contain plastifier, which potentially has little effect on melting temperature but gets glass transition temperature way down. Incidentally this is why it's becoming softer when it heats up. At the start of the video i guessed that it would survive and hey happy that it did.
I really liked this video! You can get around the flexible tube by having your inlet and outlet pipes enter the BOTTOM of the water chamber, and then rise through the water into the headspace of the floating chamber. Gas will come in the bottom, rise through the tube in the water (or you could have it bubble through the water, but your gas generator would have to be above the water line) then it would either float the upper chamber, or pass out through the outlet pipe (depending on gas demand). This is the first wood gassifier that i have seen with any type of accumulator, and I must say, it has given me a lot of ideas!
Beautiful build. Many years ago, I played at my cousin’s house that was close to a coke plant. It was alway fascinating watching the gas storage tanks rise and lower, and I always wondered what was going on. At 70 years old, now I know. Thank you.
A suggestion. The condensate is called wood vinegar and has many agricultural applications. Thanks for the work you've done to explain this process so well!
Silicone tubing would work You could put the inlet into the bottom tank, but you still need a small amount of flexibility A gasometer normally has 3 walls, the middle one being the top, the cavity is normally filled with oil iirc If you fill the main chamber with water initially, then when you get sufficient gas you could drain main chamber (bottom inlet would help with this), that would give you more room for gas, and lighter to carry
PTFE is perfectly flexible and suitable for the application shown in this video. It will hold significantly more pressure as a result of the increased stiffness, which could prove useful if weight is added to the gasometer to compress the wood gas. Additionally, the melting point of PTFE is 327 degrees C compared to the lower 300 degrees C of silicone rubber. Either one is better than the vinyl(?) tube in the video.
I am enjoying this video series. My late Grandpa and his late brother converted their car to run on wood gas here in Melbourne Australia during WW II to get around the petrol rationing problem. Back in the late 70's I can recall a couple of gasometer tanks near Heidelberg being dismantled as the town gas supply system matured.
It's really awesome seeing you doing so much experimenting with wood gas. Like I said last time, try using ordinary trash, like paper, cardboard, cereal boxes, old rags, etc. as production fuel at some point. It may be a bit harder to use with your current setup, but I think it would be worth it to see how much gas you could produce from it compared to regular wood. And on that subject, it might be interesting to see how much you get from fresh wood compared to dead and dry wood. Also, bringing your adorable bird in to give us incentive to watch the sponsor bit of your videos is really clever, and I don't regret watching it one bit. I'd love to see an off-topic video just about your bird at some point. It's super cute, and it looks like you take very good care of it. ♥
I think the amount of wood gas produced is equal in fresh or dry wood, if the wood is otherwise the same. The potential for gas produced is not ruled by freshness, it just means it has more water. At least that's what i have always thought. Before the wood will pyrolyze and gasses will exit the wood material, water has to dissipate from it and that takes time and energy so the process is just slower. That could actually be a test in itself; how much dryness affects before the wood gas starts to produce.
If you run your gas line in the bottom it can bubble up through the water to help clean the wood gas. It would also leave the top of the moveable sleeve unobstructed. In the late 80s or early 90s I saw an article in Mother Earth News. A farmer was running a methane digester with manure. He was using a similar gas collection device only massive. It was so big it had a pulley and counter weight system to make the inner bell neutrality buoyant. I believe his outer tank was concrete. I seem to recall it was as big around as a silo. With a system like that you could change the counter weight as a way to adjust the gas pressure.
It's creosote. A few decades ago, it was used to treat utility poles, railroad ties, etc. Here in the USA, general sales of creosote was banned by the EPA in 1986.
@@ThatOneFriendlyDude It's extremely carcinogenic. It's roughly thethe same as cigarettes' tar, just more concentrated, it'll give you all sorts of nasty cancers. Also, every kind of heavy metal found in low amounts in the starting wood will be concentrated in it.
I know this was part of my suggestion on the last video and apologize for the repeat. If you add a copper coil and an intermediate collection can right after the coil but before the tubing you will cool the gas significantly before it hits your tubing thus increasing its life span and you get the added benefit of collecting the condensate before it hits the storage container. Similar to how alcohol is condensed in a still.
But the tar by-product would condense and cool within the condenser coils, whereby clogging the system and eventually causing a back pressure into the gasifier can... please tell if I have this wrong?
@@johnjulie6657 a very low tech way of fixing that is putting a longer outlet pipe from the furnace. And taking a cue from natural gas piping place a T fitting with a pipe going down. Place a cap or preferably a valve at the end. Anything heavier than the gas will sink into the down pipe. Every now and then crack open the valve to empty it out.
As always it is great to see your progress and learning about this process, but best of all is your beautiful black headed caique, they are my favorite bird to ever have had as a part of my life.
You could put in a dirt pocket or drip leg (used in the piping trades) to collect the tar as it goes through the tube, then you could just blow off the tar and condensate to keep that tube from getting clogged over time!
Hi I'm Troy from Australia I'd like to say thank you im unable to work full time so I have little money I'm renovating my tiny home . every little bit helps . thanks you.
Use bungie to compress it and put a hardline into bottom of your gasometer with a line running inside the inner tube to eliminate the need for a flexible line. Also put a box inline between stove and gasometer to collect tar. This is awesome. Thank you.
Now you need to make it fuelled by a solar concentration lens so that you dont have to waste the wood to heat the fire, it can all go into making gas. Then you need to compress it and store it and run an engine on it.
Braided steel cables (the ones meant for hot water hookups) or PEX (polyethylene cross link) tubing can't handle combustion temperatures but they are at least more heat resistant than vinyl and should have common links with standard plumbing fittings.
I work with systems that measure exhaust gases from combustion engines. Those gases are hot and need to be kept at temperature to avoid condensation. To keep the gases heated we use so called flexible heated lines which use PTFE or PFA tubing inside, PFA being more chemically resistant (as far as I know). As you don't need to keep the gas heated, the tubing itself should be sufficient. It's not as flexible as vinyl tubing, but I'm confident you can figure something out.
Your videos are my favorite to watch. I was inspired to make a storm glass using your methods and did so. I gave it as a gift to my dad using a nice glass jar that I found in a grocery store. Thank you for your for everything you do and i'm always excited to watch more of your content. Cheers from Seattle.
Dear NightHawkInLight, I have come up with a few cool things you could make a video on using wood gas. 1. Compress cleaned gas into a tank and use it in a grill or gas lantern. 2. You could run a small generator off of it and/or see how big of a generator it can power. 3. Make oil and purify it into gasoline/ diesel fuel. 4. Run a propane fridge off of the gas 5. It would be more work but a go kart running off wood gas would be cool. It could use compressed gas.
Cool video man! You might try adding a scale in inches with a permanent marker down the side of the inner chamber to help gauge the amount of gas being produced or used. It’s great to see that people are still interested in this kind of tech.
I live in the San Luis Valley of Colorado where many of the shallow artesian (free flowing) domestic wells also produce a quantity of methane. I know a fellow who made a giant gassifier. He took a 1000 gallon stock tank and plumbed the output of his well into the center bottom of that tank. He then inverted a slightly smaller stock tank into the 1000 gallon tank. A valve was brazed in the center top of the inverted tank. Stock tanks of this size are heavy, but once the inverted tank had lifted several inches, he had enough pressure to do all of his cooking and heated a small room. The artesian overflow watered his livestock and his domestic water had slightly higher pressure and tasted better. He says he learned this from oldtimers in the neighborhood.
5:18, the tube I would suggest using would be 100% Silicon. It should be rated for at least 450 F vs Vinyl Tube's 150-175ish F. It's also non porous so in theory it should be easier to clean all the soot buildup off of too. Oh and it's very flexible.
Riley McDowell, good question there are two big factors I would consider with that. The first being because they are opaque it would be much harder to tell what is going on inside them so visual assessment of gas production would be impossible for the tubing. The other concern I'd have is though many are made to be rust resistant would the heat or even the byproducts like soot, methanol or things like potassium/sodium/calcium carbonate that accumulate over time in the tube affect that?
Polymer tubing for laboratory glassware use, Tygon for instance, might be pretty good contenders as well, if a little more expensive, assuming one can strike a good balance between flexibility and resistance to heat and chemical attack.
If you want fixed metal pipes you could just install a thin U shaped metal tube that goes down trough the water and up above it. It's essentially filling the tank from the inside, not trough a valve.
Rafael has a valid point. A long Tube surrounded by water will pretty much act as a condensator and collect moisture from the wood, just like the PVC tubing, but worse. Attaching a small reservouir at the bottom would solve that problem easily and with no big effort.
The gas will self clean with or without water. I build gasifiers and I use a design that I came up with that I call a expansion tank that works on the same theory as air conditioning and Refrigeration where you have gas passing through a small tube into a large chamber where it cools down due to the expansion of the woodgas and while it's cooling down it's losing humidity in the gas along with other contaminants that will flow to the bottom of the expansion chamber. I also use a traditional method a passing it through filter media but I use a tri-filter setup to further capture water and humidity along with other contaminants in the gas. What you built works really well especially for a demonstration but it would be impractical for running an engine because you'll need a larger volume of steady wood gas for power production even for a home setup. You made a really good demo video. Thanks for the Post
Maybe you could add a three way connector with a collection vessel to recover the liquid that condenses out of the wood gas? It's going to be mostly water at first, but should also contain a variety of hydrocarbons and aromatic compounds (wood-tar creosote). These having low miscibility with water, they should separate and could in principle be easily recovered. Creosote is a cool substance, with some interesting uses, like treatment of wood.
It would be a great idea to compress all of collected and filtered gas with an old refrigerator compressor or a modified bike pump (I've seen people making pumps out of pvc pipe that are able to produce more than 100psi) into some pressurised container for later use. Your low pressure container is great for collecting gas before it could be compressed
@@ellenorbjornsdottir1166 I'm not sure what you're asking. But form the various websites describing vehicles running of wood gas it seems that the production of the gas was produced on sight directly feeding the engine. Also, the efficiency was equivalent to gasoline efficient vehicles, including transportation of the wood fuel. p.s. I'm no expert on this subject, although I'm indentured by it. Having said that, I don't think this is an alternative as a replacement of the gasoline engine i.e. "The Green Deal." There's just not enough of the feed stock around, just like ethanol. There are some plants worldwide operating on this fuel because they have a feed stock of waste from the products they harvest. Also FEMA has designs for producing wood gas for generators. but it's not meant as a replacement of the electric grid, rather it's to compliment it during emergencies when the grid is down.
I'm obsessed with this! I already make charcoal from willow on a small scale and it never occurred to me to catch the gas for later, could you possibly do a short video on a diy way to clean and condense the gas into methanol and maybe it's potential uses too? Thank you for all you do on this channel it's amazing to sit and watch through it all.
Not sure if this has been mention but a small heat exchanger before the tubing would stop any danger of it melting the tube I have used similar distilling lavender oil just a tube the same as the top tube with a water jacket fitted around it you can either have a pump set up to move the water around or just make a water bath and just top up with cool water occasionally to keep it cool. This is also a great idea for storing hydrogen from a solar electrolysis unit as well. Thanks for some great ideas
the build is really informative. i have some ideas for improvements though like i didnt see a pipe leading into the water i dont think your filtering the gas all that much without it going into the water first. if you do put the pipe on it and you want the cleanest gas you can get i would recommend a diffuser of some kind at the end of the pipe which will increase the surface area of gas touching the water. i was looking for a way to contain some gases i intended to make soon i love this idea thank you so much for posting it i love your content.
Those experiments are awesome, and I can't wait to see what will happen in the future, indeed 😍 About tubing, I know there are some kind of silicone pipes which are capable of dealing with some high temperature (up to around 300ish C, which is about 500ish F), so you should be able to find something (but I see also a lot of comments in that sense): but I live in Italy so I can't tell for sure where to find those things in USA (except something like ebay, amazon or similar) More than that, have you considered putting a longer piece of tubing (like 4-5mt/12-15ft) which a part is submerged in some cold water? This might help both with condensation and lowering the overall temperature of the outgoing gases.
I did a lot of r and d on gasification back in the day and we used a much larger gasometer and gasifier. We had to stack lead weights on top of it to get the pressure to run a small generator.
Could you put a condener coil(similar to a reflux alchohol still) on the upright brass pipe, to lower the temp of the gas. Having it on the upright would also hopefully allow any tar to fall back into the gasifier, maybe.
Great video! I love your style of making videos! I am working on something really similiar for my oxyhydrogen generator. However, I am also trying to store it under a slight pressure by placing a 10 kilogramm weight on top of the tube, so that more gas fit's inside.
Make sure that you separate the gasses and store them in separate containers. Storing oxyhydrogen together in a tank like this would be an explosion waiting to happen.
NightHawkInLight Of course I know that, and I already made a lots of experiences with oxyhydrogen in the past. Storing about 5 liters is really no problem, its not that huge explosion, compared to other explosives. Seperating the gases using gravity works a little bit and reduces the amount of oxygen in the mixture, however, there is still enough left for a slow combustion. So I am going to find another way of doing it🤔☺️
Freizeitflugsphäre it's pretty easy to separate the two gases if you're generating it through electrolysis. You use a wide basin of solution, and use separate catchment containers above the anode and cathode. You can even use two separate containers if you have a solution-filled tube connecting them. The hydrogen reservoir will need to be twice the volume of the oxygen one.
Great job! Possibly add a radiator or another water tank to bubble the gas through to cool it off before reaching the vinyl tubing. This would also help with purification.
I like how you can see the gas flow through the vinyl pipe, but I think a insulated hose like the type that goes from the water source to the toilet might work better and be easy to retrofit in your application. Great job!
I think you can use a coil of copper pipe to cooling off the gas a little before it enter the plastic pipe? That way the gas will not too hot to melt the tube
vinyl tube can easily stand the heat. It softens but wont melt and can easily do 300ºC without burning. If its not smoking/smelling and getting brown then its ok.
Technically, there is a risk of compression igniting this mixture, as it *can* contain oxygen. In order to keep it safe, you MUST intercool the gas, or compress it very slowly, to prevent it from getting too hot from adiabatic compression. So long as you keep it cool, it should be ok. You will eventually (around 120PSI, depending on the composition of the volatiles) compress it enough to condense the volatiles, at which point, you can bleed off the N2, CO, CO2 and O2, which will leave you with almost exclusively combustible material
Great video! I'm currently conducting a research project on the potential of biomass energy around the world and stumbled on your video. How great to know anyone can learn how to make these things!
Somewhere on YT a guy filled a air bed mattress with the gas...put some weight on top (sand or boards)...worked nicely. It also had a greater storage volume...cheap and easy to make.
I love your collector. I'm wondering about the chemistry of the water over time as it becomes saturated with tars and other combustion byproducts. The viscosity must be increasing and at some point will need to be exchanged. After a number of runs check to see if there is stratification or settling of particulates. It might be evaporated to reduce the volume. The byproducts may also be environmently detrimental if not hazardous. Then again if in fact there is a substantial solid component when dried it might be combustible and used in subsequent cycles.
I solved your little tube puzzle. Make the tube rigid, and instead of leading it in to the top cylinder, lead it in to the center bottom of the bottom cylinder. It will bubble the gas upwards the middle, filtering the gas nicely and cool the gas down in the process, allowing for more efficient storage. And now you're thinking with rigids. :D
5:27 well I have an idea.... Use steel wire reinforced cooking gas pipe.... It's flexible, heat resistant, erosion resistant, and air tight.... Easily available at dollar store
... Is it weird to ask for a 10 minute video of you just playing with your bird? I think that's the most satisfying part about watching your sponsor ads at the end
Excellent presentation, love what your doing. I saw somewhere,where they reckoned the USA has enough biomass now to replace 67% of the fossil fuel it uses !
Amazing. If we take a heavier metal tube for the inside. It will act like weight and so the pressure will be greater. You have given me thoughts on a new project. Thnaks a lot for your videos. Keep them coming.
If you make two pipes go under the foot and enter the lower fixed container in the center; going through all the water and ending just after the waterline you could both fill it AND use the gas without any flexible hoses involved. Also without creating any extra friction between the cylinders.
+1 First thing I thought of too Cut a small piece of copper pipe to reach the centre and just bubble the gas through the water. Bonus extra filtration too.
That looks like something that could be ramped up to a fairly large size maybe 500 gallons or so and then be more useful. Although that container looks like it holds a lot of gas, since it is such low pressure is really very little compared to a highly compressed small cylinder. Nonetheless, very interesting and clever contraption there. And with easy to follow instructions at a very low cost. It seems love watching your videos. inexpensive yet very effective. Love watching your videos. There always interesting and fun.
I fully understand the concern about the vinyl tubing. And over time it will break down due to the heat and the mild corrosiveness of the hot gasses. But silicon tubing is designed to handle higher temperatures and can withstand the corrosiveness of the hot gasses. Thusly, you would maintain the flexibility you need.
I was hypnotized by your project! Very cool one! I come very late but you could use PFA or PTFE (resist around 220°C and chemicaly inert) tube instead of vinyl
i could say that every video from you. irealy like your kindness and your passion to your work. i can see, when you are burning your fuel that that is a true succses to you. Please go on with your work - it deliveres a great message like styropyros videos for example, that learning - especially learning by doing is a good way of expanding our knowledge. are you planing to pressurise it until its liquefaction and fill it up in cans?
I built a slightly larger version of this. I used a commercial awning canvass like material to make a pillow tank the size of a pickup truck. Flat there is no air in it and so inflated it is undiluted syngas. I collected some of the distillate from the gasifier in a beaker and so about a cup full of light yellow to brown light viscosity liquid. My reaction to the odour from this was that it smelled like the essence of cancer. I would NOT NOT NOT recommend to breath or ingest this in any form what-so-ever. Other than that the process gummed up all our 4 inch transfers hose interiors with a tar like sludge before going into a heat exchanger and so cleaning/filtering and cooling all needed special consideration when clean wood stocks were used. Coal or Municipal Solid Waste would have unique characteristics of their own. The syngas produced was suitable to run a 30kW gas turbine at 95000 rpm which was an ultimate modern application of town gas from the 100 plus year history of this technology. I enjoyed the demo and so thanks for sharing.
My dad’s farm had a 1000 gallon methane digestor that worked from hog manure. Very similar to your set-up here using tractor inner tube for a seal and a compressor to concentrate the gas. The methane was then used in the tractor on the farm. The previous owner of the hog farm barbecued himself with this contraption from an errant spark so my dad would never use it and it rusted away to junk while I was growing up.
Hey, so what I was wondering. What would be stopping you from taking the clean gas and compressing it into a propane tank? That would make it much more easy to transport and use
I've been wanting to do essentially that but my fear has been that I don't know the combustion point for the Woodgate, so it could conceivably turn my air compressor into a diesel engine essentially and possibly blow up on me. if any has done this or knows some hard data regarding combustion point I'd love to hear from you.
@@amharrach as long as there is no oxygen being introduced and the tank is purged there should be no issue as combustion would be impossible, super cooling the pressure vessel would also remedy this issue; would be an interesting project w/ a bomb squad near by ahaha
@@amharrach You might try building a set up like vid, but then sealing the two pipes (the wood gas collector) in the "full" or extended position. After that, plumb the outlet to your propane tank, then introduce water through the inlet valve to compress the gas. Once compressed, open the outlet valve to the tank. Obviously there's a bit more to it, but this should give you food for thought.
Hi. I'm late but I'll give my two cents. Compressing wood gas is not safe and also not economical . Due to its low atmospheric pressure . This is the one drawback of wood/town gas . It excels at being used on the spot
Very cool!!! You have answered some of the bigger questions I have had about wood gas, but I do have a few more. Can you store this gas long term? Is it compressible for storage space management? If so, is that something that can be done as a DIY project?
4 years later... yes you can store for quite a while. several months. however it will slowly dissolve into the water. higher the pressure the quicker it will dissolve. I've tried floating a layer of oil on top of the water but cannot tell yet if its making a difference.
Sweet gravity bong bro When you do the burn tests, should add a venturi mixer like the head of a propane torch so you can pre-mix the air and fuel before igniting it, much more satisfying flame that does not need a constant ignition source!
If you missed my last video where I build the gassifier used for this project, you can watch it here: th-cam.com/video/HQIW4dVVokE/w-d-xo.html
Who would miss one of your videos?
To bubble the water from the bottom to the top means that the gas needs to have enough pressure to force the water out of the tube. That's more pressure than my gassifier generates in this setup.
silicone rubber is a thermal set, so it is pretty heat resistant
I think a shower head hose might be able to survive the heat better.
You should make an airtight crockpot to heat the wood inside, leading to a canister to store the gas. Something I found online: Higher temperatures improve hydrogen yield in the gaseous product while CO yield decreases. Under nitrogen atmosphere, after 2 s at 950 °C, 76% (daf) of the mass of wood is recovered as gases: CO, CO2, H2, CH4, C2H2, C2H4 and H2O. Tests performed under steam partial pressure showed that hydrogen production is slightly enhanced.
Instead worrying about what type of tube you use , you could use a condenser to cool the gas before it reaches the tube
I was thinking almost the same thing...just use a cooling system on the pipe and hose like the worm in a still
And condense out tar that blocks it all up.
I'd say just run it though a water column. It'll cool the gas and also remove the impurities.
Absolutely correct! Coil condenser with a collection pot to capture contaminates at the bottom works very efficiently.
I've used this method for years to convert acetone to diketene with great success.
Isn't the condensed liquid diesel? so a diesel collector in the middle will prevent condensation in the pipe and melting the pipe.
I like how pretty much every by-product of this process is a useful material. The charcoal has lots of uses, the tar can be used to make wood rot-resistant, the wood gas is a decent fuel. There's really no waste.
Charcoal ash can make soap, and the chemistry goes on forever
and i can grow my own fuel . and it also grows naturally . just takes a bit of work thats all

That's so cool that you read all of the comments! I love how meticulous you are in your projects and how you're always showing where things didn't go as expected so we can learn from that too.
We had three massive gasometers in my town, a few minutes walk away from where I live, they were a sort of landmark you could see for miles. I miss them oddly enough.
Just one dude who’s way into gasometers
In my city in Germany they just got them a different purpose, they are now exhibition rooms for museums and a restaurant.

Gabriel Schoene in a possessive context, it's 'your'*.

My goodness, you are really clever using the gas pipe. And using the epoxy to seal the bottom and the seam seal. Great job fella too.
7:05 the condensation is a mixture of wood alcohol (methanol), gasoline, tar and diesel. All of them are also valuable. You can set multiple filtration setups to collect them as well.
how would you separate the four...also is the water in the gasometer tainted in anyway?
Fractional distillation
Could actually be harvested with some water-cooling of the pipes, perhaps a spiral chamber with an outlet, then the gas passed on to the gasometer will also be purer but of course also denser, so perhaps you'd need a spring or something to lower the pressure in there, basically sucking the gas in.
Tube with in and out connection, cooled by water, so it condensates to pipe surface and collects on the bottom as a pool, witch can then be with regulated flow valve let empty to container.
Separation would be using standard oil industry techniques of fractional distillation as it was mentioned, where start product is heated and released to chamber. Due lack of oxygen it wont burn, but turn into gas. Chamber has several different levels with different levels of heat. Gasoline or methanol is easiest to turn to gas and will float on top chamber, where as heavier oils that take more temperature to turn into gas will condensate on lower levels, where these can be collected to separate containers, filtered again and put on use.
I would consider 'cracking' the distillate while it's still a avpour by heating further over some kind of catalyst. That way you will get more gas from the liquid portion, so more yield of usable gas.
I don't know about anyone else, but this kind of stuff fascinates me. I can't wait to build one of my own. People like you need to be running this country. Take Care.
His smile when he turned it on and it worked, priceless :)
Silicone tubing is good to have around. It's short term temperature resistant to well over 300°C, long term to about 200. It won't melt ever, and if it starts to discolour, it's degrading or basically slowly burning up.
Vinyl has a fairly high melting temperature... i forget... but it's a very hard plastic, so tubing must contain plastifier, which potentially has little effect on melting temperature but gets glass transition temperature way down. Incidentally this is why it's becoming softer when it heats up. At the start of the video i guessed that it would survive and hey happy that it did.
Hey Siana! Singularity Viewer user here.
He needs stainless flex hose.
Why oh why on earth would I watch any other TH-cam! 2 years it took to find you.. a $20 wood gasified camp stove brung me here. Thanks
I really liked this video!
You can get around the flexible tube by having your inlet and outlet pipes enter the BOTTOM of the water chamber, and then rise through the water into the headspace of the floating chamber. Gas will come in the bottom, rise through the tube in the water (or you could have it bubble through the water, but your gas generator would have to be above the water line) then it would either float the upper chamber, or pass out through the outlet pipe (depending on gas demand).
This is the first wood gassifier that i have seen with any type of accumulator, and I must say, it has given me a lot of ideas!
Great suggestion
Beautiful build. Many years ago, I played at my cousin’s house that was close to a coke plant. It was alway fascinating watching the gas storage tanks rise and lower, and I always wondered what was going on. At 70 years old, now I know. Thank you.
A suggestion. The condensate is called wood vinegar and has many agricultural applications. Thanks for the work you've done to explain this process so well!
I love how you are able to make simple, easy to reproduce designs in your projects. You are my favorite TH-cam content provider!
I love the wood gas content it's fascinating how something so simple could be used for just about anything.
Get some PTFE tubing. It's the most temperature resistant material that's flexible. You need specific connectors for it, but it will work up to 500F.
Great tip!
Or lab rubber tubing, a lot cheaper, from amazon or eBay is easy to find
Silicone tubing would work
You could put the inlet into the bottom tank, but you still need a small amount of flexibility
A gasometer normally has 3 walls, the middle one being the top, the cavity is normally filled with oil iirc
If you fill the main chamber with water initially, then when you get sufficient gas you could drain main chamber (bottom inlet would help with this), that would give you more room for gas, and lighter to carry
PTFE is not THAT flexible and not THAT temperature resistant, it starts to slowly give up around 250°C. Silicone beats PTFE on both accounts.
PTFE is perfectly flexible and suitable for the application shown in this video. It will hold significantly more pressure as a result of the increased stiffness, which could prove useful if weight is added to the gasometer to compress the wood gas. Additionally, the melting point of PTFE is 327 degrees C compared to the lower 300 degrees C of silicone rubber. Either one is better than the vinyl(?) tube in the video.
I am enjoying this video series. My late Grandpa and his late brother converted their car to run on wood gas here in Melbourne Australia during WW II to get around the petrol rationing problem. Back in the late 70's I can recall a couple of gasometer tanks near Heidelberg being dismantled as the town gas supply system matured.
A really good system, producing two fuels: the gas and charcoal. Nice!
There's methanol being produced as well, hes just not collecting it.
im amazed on how dedicate you are, amazing job!
you improved the desing a lot this time
It's really awesome seeing you doing so much experimenting with wood gas. Like I said last time, try using ordinary trash, like paper, cardboard, cereal boxes, old rags, etc. as production fuel at some point. It may be a bit harder to use with your current setup, but I think it would be worth it to see how much gas you could produce from it compared to regular wood.
And on that subject, it might be interesting to see how much you get from fresh wood compared to dead and dry wood.
Also, bringing your adorable bird in to give us incentive to watch the sponsor bit of your videos is really clever, and I don't regret watching it one bit. I'd love to see an off-topic video just about your bird at some point. It's super cute, and it looks like you take very good care of it. ♥
I think the amount of wood gas produced is equal in fresh or dry wood, if the wood is otherwise the same. The potential for gas produced is not ruled by freshness, it just means it has more water. At least that's what i have always thought. Before the wood will pyrolyze and gasses will exit the wood material, water has to dissipate from it and that takes time and energy so the process is just slower.
That could actually be a test in itself; how much dryness affects before the wood gas starts to produce.
And vinegar
If you run your gas line in the bottom it can bubble up through the water to help clean the wood gas. It would also leave the top of the moveable sleeve unobstructed. In the late 80s or early 90s I saw an article in Mother Earth News. A farmer was running a methane digester with manure. He was using a similar gas collection device only massive. It was so big it had a pulley and counter weight system to make the inner bell neutrality buoyant. I believe his outer tank was concrete. I seem to recall it was as big around as a silo. With a system like that you could change the counter weight as a way to adjust the gas pressure.
1:49 very satisfying sound. Not the scraping, but the "thum" that followed.
Using that double walled pipe and end cap is brilliant!
I was looking for a light weight solution, and this seems very suitable!
You should try using the wood tar for something. Maybe make a 14th century ship with it. ;)
It's creosote. A few decades ago, it was used to treat utility poles, railroad ties, etc. Here in the USA, general sales of creosote was banned by the EPA in 1986.
@@gyrgrls damned epa
John Bond why was it banned? Just curious since I honestly don’t know anything about it.
@@ThatOneFriendlyDude It's extremely carcinogenic. It's roughly thethe same as cigarettes' tar, just more concentrated, it'll give you all sorts of nasty cancers. Also, every kind of heavy metal found in low amounts in the starting wood will be concentrated in it.
@@gyrgrls Nastiest splinters you will EVER have in your whole life.
His face so friendly, especially when he smile :P
Agree
I know this was part of my suggestion on the last video and apologize for the repeat. If you add a copper coil and an intermediate collection can right after the coil but before the tubing you will cool the gas significantly before it hits your tubing thus increasing its life span and you get the added benefit of collecting the condensate before it hits the storage container. Similar to how alcohol is condensed in a still.
cooper and brass can be considered as catalyst as well and purify the gas
But the tar by-product would condense and cool within the condenser coils, whereby clogging the system and eventually causing a back pressure into the gasifier can... please tell if I have this wrong?
@@johnjulie6657 yes you are right , i had the same problem with ,mine . the solution was a cyclone filter and wood chips and shavings.
@@johnjulie6657 a very low tech way of fixing that is putting a longer outlet pipe from the furnace. And taking a cue from natural gas piping place a T fitting with a pipe going down. Place a cap or preferably a valve at the end. Anything heavier than the gas will sink into the down pipe. Every now and then crack open the valve to empty it out.
The smile in your face when lighting the torch - priceless :)
That was the best design and explanation I have seen about gasifiers and a gasometer. Very well done! Thank you!
As always it is great to see your progress and learning about this process, but best of all is your beautiful black headed caique, they are my favorite bird to ever have had as a part of my life.
THIS IS QUALITY CONTENT...... Marvelous work.. bro .... And very educative...
You could put in a dirt pocket or drip leg (used in the piping trades) to collect the tar as it goes through the tube, then you could just blow off the tar and condensate to keep that tube from getting clogged over time!
Hi I'm Troy from Australia I'd like to say thank you im unable to work full time so I have little money I'm renovating my tiny home . every little bit helps . thanks you.
Use bungie to compress it and put a hardline into bottom of your gasometer with a line running inside the inner tube to eliminate the need for a flexible line. Also put a box inline between stove and gasometer to collect tar. This is awesome. Thank you.
Now you need to make it fuelled by a solar concentration lens so that you dont have to waste the wood to heat the fire, it can all go into making gas. Then you need to compress it and store it and run an engine on it.
Or connect it to a furnace that is already going to be producing pyrolysis capable heat.
Braided steel cables (the ones meant for hot water hookups) or PEX (polyethylene cross link) tubing can't handle combustion temperatures but they are at least more heat resistant than vinyl and should have common links with standard plumbing fittings.
I work with systems that measure exhaust gases from combustion engines. Those gases are hot and need to be kept at temperature to avoid condensation. To keep the gases heated we use so called flexible heated lines which use PTFE or PFA tubing inside, PFA being more chemically resistant (as far as I know). As you don't need to keep the gas heated, the tubing itself should be sufficient. It's not as flexible as vinyl tubing, but I'm confident you can figure something out.
NightCaiqueInLight
Bingo, new subchannel name for bird antics.
That was by far the easiest cleanest woodgas filter I've seen
Yep no filter beats giving the gas time to settle.
Your videos are my favorite to watch. I was inspired to make a storm glass using your methods and did so. I gave it as a gift to my dad using a nice glass jar that I found in a grocery store.

*GAS
Dear NightHawkInLight,
I have come up with a few cool things you could make a video on using wood gas.
1. Compress cleaned gas into a tank and use it in a grill or gas lantern.
2. You could run a small generator off of it and/or see how big of a generator it can power.
3. Make oil and purify it into gasoline/ diesel fuel.
4. Run a propane fridge off of the gas
5. It would be more work but a go kart running off wood gas would be cool. It could use compressed gas.
I don't think a propane fridge will work. Any stove will though with an appropriate jet.
Cool video man! You might try adding a scale in inches with a permanent marker down the side of the inner chamber to help gauge the amount of gas being produced or used. It’s great to see that people are still interested in this kind of tech.
I live in the San Luis Valley of Colorado where many of the shallow artesian (free flowing) domestic wells also produce a quantity of methane. I know a fellow who made a giant gassifier. He took a 1000 gallon stock tank and plumbed the output of his well into the center bottom of that tank. He then inverted a slightly smaller stock tank into the 1000 gallon tank. A valve was brazed in the center top of the inverted tank. Stock tanks of this size are heavy, but once the inverted tank had lifted several inches, he had enough pressure to do all of his cooking and heated a small room. The artesian overflow watered his livestock and his domestic water had slightly higher pressure and tasted better. He says he learned this from oldtimers in the neighborhood.
I’m so happy I stumbled across this channel, DIY on topics right up my alley.
5:18, the tube I would suggest using would be 100% Silicon. It should be rated for at least 450 F vs Vinyl Tube's 150-175ish F. It's also non porous so in theory it should be easier to clean all the soot buildup off of too. Oh and it's very flexible.
TrollFaceTheMan could he also use some metal braided lines? He could probably get some at an auto parts store
Riley McDowell, good question there are two big factors I would consider with that. The first being because they are opaque it would be much harder to tell what is going on inside them so visual assessment of gas production would be impossible for the tubing.
The other concern I'd have is though many are made to be rust resistant would the heat or even the byproducts like soot, methanol or things like potassium/sodium/calcium carbonate that accumulate over time in the tube affect that?
Polymer tubing for laboratory glassware use, Tygon for instance, might be pretty good contenders as well, if a little more expensive, assuming one can strike a good balance between flexibility and resistance to heat and chemical attack.
If you want fixed metal pipes you could just install a thin U shaped metal tube that goes down trough the water and up above it. It's essentially filling the tank from the inside, not trough a valve.
I'm not sure how well that would work, since the pressure from the wood gas production would have to push the water out of the U shaped tube.
@Rafael Dos Santos
That's what it is doing with the current setup too. So it should be fine. I'd go with the internal tube.
Rafael has a valid point. A long Tube surrounded by water will pretty much act as a condensator and collect moisture from the wood, just like the PVC tubing, but worse.
Attaching a small reservouir at the bottom would solve that problem easily and with no big effort.
Fantastic work. You did a great job on this build and video!!
The gas will self clean with or without water. I build gasifiers and I use a design that I came up with that I call a expansion tank that works on the same theory as air conditioning and Refrigeration where you have gas passing through a small tube into a large chamber where it cools down due to the expansion of the woodgas and while it's cooling down it's losing humidity in the gas along with other contaminants that will flow to the bottom of the expansion chamber. I also use a traditional method a passing it through filter media but I use a tri-filter setup to further capture water and humidity along with other contaminants in the gas. What you built works really well especially for a demonstration but it would be impractical for running an engine because you'll need a larger volume of steady wood gas for power production even for a home setup. You made a really good demo video. Thanks for the Post
Why is it so satisfying to hear him pull apart the two cylinders at 1:49?
Really like this series and can't wait to see what you have planned for the wood gas.
Maybe you could add a three way connector with a collection vessel to recover the liquid that condenses out of the wood gas? It's going to be mostly water at first, but should also contain a variety of hydrocarbons and aromatic compounds (wood-tar creosote). These having low miscibility with water, they should separate and could in principle be easily recovered.
Creosote is a cool substance, with some interesting uses, like treatment of wood.
or also burn it if you atomize it like with kerosene or most oils.
Terpenes as well if gasifying pine wood.
A water trap.
The brown liquid can be fractionally distilled to recover the methanol in it.
I'm loving these wood gas videos! keep em coming!
It'd love to visit this guy one day. It's be amazing to see all the stuff he'd built and have a stimulating conversation.
The smile, when you lit the gas, is contagious. Ty 🙂
It would be a great idea to compress all of collected and filtered gas with an old refrigerator compressor or a modified bike pump (I've seen people making pumps out of pvc pipe that are able to produce more than 100psi) into some pressurised container for later use. Your low pressure container is great for collecting gas before it could be compressed
Compression rates are not good. I had the same thought. I found that a propane tank would only get a car 2 miles on the road.

@@ellenorbjornsdottir1166 I'm not sure what you're asking. But form the various websites describing vehicles running of wood gas it seems that the production of the gas was produced on sight directly feeding the engine. Also, the efficiency was equivalent to gasoline efficient vehicles, including transportation of the wood fuel.
p.s. I'm no expert on this subject, although I'm indentured by it. Having said that, I don't think this is an alternative as a replacement of the gasoline engine i.e. "The Green Deal." There's just not enough of the feed stock around, just like ethanol. There are some plants worldwide operating on this fuel because they have a feed stock of waste from the products they harvest. Also FEMA has designs for producing wood gas for generators. but it's not meant as a replacement of the electric grid, rather it's to compliment it during emergencies when the grid is down.
I'm obsessed with this! I already make charcoal from willow on a small scale and it never occurred to me to catch the gas for later, could you possibly do a short video on a diy way to clean and condense the gas into methanol and maybe it's potential uses too? Thank you for all you do on this channel it's amazing to sit and watch through it all.
Get a burner and use it to cook food/bbq
Not sure if this has been mention but a small heat exchanger before the tubing would stop any danger of it melting the tube I have used similar distilling lavender oil just a tube the same as the top tube with a water jacket fitted around it you can either have a pump set up to move the water around or just make a water bath and just top up with cool water occasionally to keep it cool. This is also a great idea for storing hydrogen from a solar electrolysis unit as well. Thanks for some great ideas
love the efficient water-seal below the gas.
Wow, that burns cleaner than I expected. That system is worth refining and scaling up.
I believe every single commercial should have the person explain the product while playing with a parrot in the foreground.
the build is really informative. i have some ideas for improvements though like i didnt see a pipe leading into the water i dont think your filtering the gas all that much without it going into the water first. if you do put the pipe on it and you want the cleanest gas you can get i would recommend a diffuser of some kind at the end of the pipe which will increase the surface area of gas touching the water. i was looking for a way to contain some gases i intended to make soon i love this idea thank you so much for posting it i love your content.
Those experiments are awesome, and I can't wait to see what will happen in the future, indeed 😍
About tubing, I know there are some kind of silicone pipes which are capable of dealing with some high temperature (up to around 300ish C, which is about 500ish F), so you should be able to find something (but I see also a lot of comments in that sense): but I live in Italy so I can't tell for sure where to find those things in USA (except something like ebay, amazon or similar)
More than that, have you considered putting a longer piece of tubing (like 4-5mt/12-15ft) which a part is submerged in some cold water? This might help both with condensation and lowering the overall temperature of the outgoing gases.
Ciao dall' Italia ,ogni volta che guardo questo ,mi piace sempre di più
I did a lot of r and d on gasification back in the day and we used a much larger gasometer and gasifier. We had to stack lead weights on top of it to get the pressure to run a small generator.
Could you put a condener coil(similar to a reflux alchohol still) on the upright brass pipe, to lower the temp of the gas. Having it on the upright would also hopefully allow any tar to fall back into the gasifier, maybe.
Great video! I love your style of making videos!
I am working on something really similiar for my oxyhydrogen generator. However, I am also trying to store it under a slight pressure by placing a 10 kilogramm weight on top of the tube, so that more gas fit's inside.
Make sure that you separate the gasses and store them in separate containers. Storing oxyhydrogen together in a tank like this would be an explosion waiting to happen.
There are a few videos on youtube where people explain how people died because of compressed oxyhydrogen being so volatile and exploding
NightHawkInLight Of course I know that, and I already made a lots of experiences with oxyhydrogen in the past. Storing about 5 liters is really no problem, its not that huge explosion, compared to other explosives. Seperating the gases using gravity works a little bit and reduces the amount of oxygen in the mixture, however, there is still enough left for a slow combustion.
So I am going to find another way of doing it🤔☺️
Freizeitflugsphäre it's pretty easy to separate the two gases if you're generating it through electrolysis. You use a wide basin of solution, and use separate catchment containers above the anode and cathode. You can even use two separate containers if you have a solution-filled tube connecting them. The hydrogen reservoir will need to be twice the volume of the oxygen one.
James Petersen But thats efficient as hell
Great job! Possibly add a radiator or another water tank to bubble the gas through to cool it off before reaching the vinyl tubing. This would also help with purification.
I like how you can see the gas flow through the vinyl pipe, but I think a insulated hose like the type that goes from the water source to the toilet might work better and be easy to retrofit in your application. Great job!
I think you can use a coil of copper pipe to cooling off the gas a little before it enter the plastic pipe? That way the gas will not too hot to melt the tube
Super cool. I think the black fuel line would take the heat all day long
vinyl tube can easily stand the heat. It softens but wont melt and can easily do 300ºC without burning. If its not smoking/smelling and getting brown then its ok.
fridge compressor
inlet-gasometer
outlet-tank
Isn't there a risk that the compressor will ignite the wood gas?
it needs oxygen to burn
It's not safe to compress this kind of gas.
Explain :)
Technically, there is a risk of compression igniting this mixture, as it *can* contain oxygen. In order to keep it safe, you MUST intercool the gas, or compress it very slowly, to prevent it from getting too hot from adiabatic compression. So long as you keep it cool, it should be ok. You will eventually (around 120PSI, depending on the composition of the volatiles) compress it enough to condense the volatiles, at which point, you can bleed off the N2, CO, CO2 and O2, which will leave you with almost exclusively combustible material
Great video! I'm currently conducting a research project on the potential of biomass energy around the world and stumbled on your video. How great to know anyone can learn how to make these things!
Somewhere on YT a guy filled a air bed mattress with the gas...put some weight on top (sand or boards)...worked nicely. It also had a greater storage volume...cheap and easy to make.
I've seen that done also. Probably one of the easier ways to go about it.
awesome job as usual, ben!
I love your collector.
I'm wondering about the chemistry of the water over time as it becomes saturated with tars and other combustion byproducts. The viscosity must be increasing and at some point will need to be exchanged. After a number of runs check to see if there is stratification or settling of particulates. It might be evaporated to reduce the volume. The byproducts may also be environmently detrimental if not hazardous. Then again if in fact there is a substantial solid component when dried it might be combustible and used in subsequent cycles.
It's combustible and it can be broken down ( cracked ) to make liquid fuels similar to diesel & gasoline.
Gravity vaporizer. Imagines the hits you would get our of that.
Have another go mate.
I solved your little tube puzzle.
Make the tube rigid, and instead of leading it in to the top cylinder, lead it in to the center bottom of the bottom cylinder. It will bubble the gas upwards the middle, filtering the gas nicely and cool the gas down in the process, allowing for more efficient storage.
And now you're thinking with rigids. :D
Have to say, the bird kept me around for the square space ad!

Is it weird to ask for a 10 minute video of you just playing with your bird? I think that's the most satisfying part about watching your sponsor ads at the end
Excellent presentation, love what your doing. I saw somewhere,where they reckoned the USA has enough biomass now to replace 67% of the fossil fuel it uses !
Amazing. If we take a heavier metal tube for the inside. It will act like weight and so the pressure will be greater. You have given me thoughts on a new project. Thnaks a lot for your videos. Keep them coming.
if you inject it at the bottom of the gasometer wont you not need a flexible tube and just use metal since the bottom doesn't move?
You'd need an airtight seal around the space between the two tubes, but that might create too much friction.
If you make two pipes go under the foot and enter the lower fixed container in the center; going through all the water and ending just after the waterline you could both fill it AND use the gas without any flexible hoses involved. Also without creating any extra friction between the cylinders.
+1
First thing I thought of too
Cut a small piece of copper pipe to reach the centre and just bubble the gas through the water.
Bonus extra filtration too.
Grimidor problem with that is the top cylinder might be too heavy now
If you inject at the bottom the wood gas is also filtered through all of the water instead of just the water at the top of the tank
That looks like something that could be ramped up to a fairly large size maybe 500 gallons or so and then be more useful. Although that container looks like it holds a lot of gas, since it is such low pressure is really very little compared to a highly compressed small cylinder.
Nonetheless, very interesting and clever contraption there. And with easy to follow instructions at a very low cost. It seems love watching your videos. inexpensive yet very effective.
Love watching your videos. There always interesting and fun.
You should fill your bottle launcher with the wood gas
I fully understand the concern about the vinyl tubing. And over time it will break down due to the heat and the mild corrosiveness of the hot gasses. But silicon tubing is designed to handle higher temperatures and can withstand the corrosiveness of the hot gasses. Thusly, you would maintain the flexibility you need.
I was hypnotized by your project! Very cool one! I come very late but you could use PFA or PTFE (resist around 220°C and chemicaly inert) tube instead of vinyl
i could say that every video from you. irealy like your kindness and your passion to your work. i can see, when you are burning your fuel that that is a true succses to you. Please go on with your work - it deliveres a great message like styropyros videos for example, that learning - especially learning by doing is a good way of expanding our knowledge.
are you planing to pressurise it until its liquefaction and fill it up in cans?
Awesome! Future project.... bio mass gasifier....?
btw the condensate is the same stuff as the condiment liquid smoke its edible and tastes pretty good you can cook with it
I built a slightly larger version of this. I used a commercial awning canvass like material to make a pillow tank the size of a pickup truck. Flat there is no air in it and so inflated it is undiluted syngas.
I collected some of the distillate from the gasifier in a beaker and so about a cup full of light yellow to brown light viscosity liquid.
My reaction to the odour from this was that it smelled like the essence of cancer.
I would NOT NOT NOT recommend to breath or ingest this in any form what-so-ever.
Other than that the process gummed up all our 4 inch transfers hose interiors with a tar like sludge before going into a heat exchanger and so cleaning/filtering and cooling all needed special consideration when clean wood stocks were used. Coal or Municipal Solid Waste would have unique characteristics of their own.
The syngas produced was suitable to run a 30kW gas turbine at 95000 rpm which was an ultimate modern application of town gas from the 100 plus year history of this technology.
I enjoyed the demo and so thanks for sharing.
Around northern towns in the UK you will often still find huge gasometers. They are all unused now but the structures are still around.
My dad’s farm had a 1000 gallon methane digestor that worked from hog manure. Very similar to your set-up here using tractor inner tube for a seal and a compressor to concentrate the gas. The methane was then used in the tractor on the farm. The previous owner of the hog farm barbecued himself with this contraption from an errant spark so my dad would never use it and it rusted away to junk while I was growing up.
Hey, so what I was wondering. What would be stopping you from taking the clean gas and compressing it into a propane tank? That would make it much more easy to transport and use
I've been wanting to do essentially that but my fear has been that I don't know the combustion point for the Woodgate, so it could conceivably turn my air compressor into a diesel engine essentially and possibly blow up on me.
if any has done this or knows some hard data regarding combustion point I'd love to hear from you.
@@amharrach as long as there is no oxygen being introduced and the tank is purged there should be no issue as combustion would be impossible, super cooling the pressure vessel would also remedy this issue; would be an interesting project w/ a bomb squad near by
ahaha
@@amharrach You might try building a set up like vid, but then sealing the two pipes (the wood gas collector) in the "full" or extended position. After that, plumb the outlet to your propane tank, then introduce water through the inlet valve to compress the gas. Once compressed, open the outlet valve to the tank. Obviously there's a bit more to it, but this should give you food for thought.
Hi. I'm late but I'll give my two cents. Compressing wood gas is not safe and also not economical . Due to its low atmospheric pressure . This is the one drawback of wood/town gas . It excels at being used on the spot
Very cool!!! You have answered some of the bigger questions I have had about wood gas, but I do have a few more. Can you store this gas long term? Is it compressible for storage space management? If so, is that something that can be done as a DIY project?
4 years later...
yes you can store for quite a while. several months. however it will slowly dissolve into the water. higher the pressure the quicker it will dissolve.
I've tried floating a layer of oil on top of the water but cannot tell yet if its making a difference.
Silicone tubing
Sweet gravity bong bro
When you do the burn tests, should add a venturi mixer like the head of a propane torch so you can pre-mix the air and fuel before igniting it, much more satisfying flame that does not need a constant ignition source!
Gasometer tubing: you could use flexible metal pipe fitting like what is used for sinks and toilets if you want something more temperature resistant.
