A propane tank should work well

Thanks, i have an old air tank as well. Im going to steal your plan if its ok 😊

Thanks for posting.

This person eats it right out of the bag 🎒 she doesnt think about when asked does she swallow it she says 60 percent that doesnt sound to good does it

Im a new subscriber

GREAT VIDEO 📹 HAVE YOU EVER HEARD OF PEOPLE EATING CHARCOAL AND COAL DUST IT HAS DANGEROUS CHEMICALS IN IT ITS HARMFU TO THE BODY WHY WOULD ANYONE WANT TO EAT CHARCOAL WELL I HAVE WATCHING VIDEOS OF PEOPLE EATING BOTH THIS PERSON EATS COAL DUST OUT OF A BOWL AND SHE EATS COWBOY LUMP CHARCOAL I CANT IMAGINE IT AT ALL YOU WILL GET CHEMICAL BURNS ON THE BODY HANDS MOUTH TOUNGE THROAT STOMACH THE WORST IS YOUR LUNGS BLACK COAL DUST I LOOKED IT UP ON GOOGLE TO SEE WHAT IT SAYS ITS NOT GOOD FOR ANYBODY TO EAT ANY THOUGHTS ON THIS LEAVE A MESSAGE

Thanks man!

A longer chimney. It'll cause more up draft to help air circulation to help burn the fuel being fed in

Love the video. Thank you.

Considering that your tank sits on a flat metal plate and not clamped/sealed shut, you wont have to worry about the number of holes in the center chimney flue. If it starts to pressurize, the tank and chimney will be lifted creating a gap around the outer edge between the tank and flat plate and thus reduce the pressure.

Really cool project

Thank you sir!!!!

Great video and thanks👍. I could not help but noticing that you may be going into labour very soon. 🤣🤣🤣💯💯💯🇯🇲🇯🇲🇯🇲👍

hi, just wondering what is the temp on the burn chamber and at the top of the heat riser? thx

I never would have considered an oil burner to heat a retort, but the amount of heat they create can be insane. What a great idea. I’m diggin it. You sir are a genius !!! A mad scientist !!! I am absolutely waiting to see the next gen of this ! Hope it works out well for you sir.

That is an EXCELLENT. Idea !!! It’s small enough to be used in the community but large enough to make a decent amount of coals. I am genuinely glad I watched this video. I was going to use a 55 gallon drum but I was worried it might be too much for the back yard as I have neighbors all around me. But this is small and portable. Thank you for the idea sir.

I have watched several videos like this with similar results. they then insulate the burn chamber with something like a ceramic blanket or a product that will withstand very high temperatures, then put a metal wrap around to keep it all together, and they get a good result. May that is worth trying

You’ve got a pretty cool design going on there. Have you considered wrapping the retort with insulation to help retain heat in the chamber ? It might help you cut down some time on your process. Good luck 🍀👍!

Great explanations, thanks for sharing your discoveries. The small inside tubes is a great idea !! By the way, would insulating the burn chamber be a good idea ??

How many hours to burn?

Ya people should try to better themself. Like ya said start with the man in the mirror. Being spiritual and focusing on god is good. But I will say it was sad to look at the loss of freedom. People couldn’t have baptisms or even birthday parties or were turned in by their neighbors. God was put in the back as preachers were arrested and churches closed but Walmart and casinos and air planes still ran. Amazon etc and big businesses grew and small businesses died. It was super frustrating to watch the hypocrisy. Also it’s kind of funny. It took the Rona to get people to wash their hands. I was washing my hands for years before haha. Before and now years after the Rona I still see people leaving the bathroom without washing their hands. It’s like even if ya don’t want the jab or ya believe in natural immunity it’s like hygiene is key. I think it was Nostradamus during the black plague that figured out those people that washed daily got sick less or more likely to survive or not get the black plague.

It’s like I was told. It doesn’t have to be pretty when you build stuff for yourself just has to be functional. I remember in high school for shop class I used scrap metal and lost points for my project for my grade cause it didn’t look good. I had a two inch hole in a pipe for a Dixie harrow for a tractor to pull. I just drop a piece of metal in and welded it. It’s like I could have taken more time to cut it to fit but it’s like I’m not selling it or charging others for my time. You’ll have lots of bad projects but overtime you get good at welding. I remember when I first started welding aluminum and it took a while to get decent and good so the welds look like the original welds on the trailer.

You could also pipe the wood gases into the burn chamber to produce more heat

I don't think you need a larger wooden pellet basket. Maybe it should even be smaller when the entire unit is rebuilt and insulated. When insulating the rocket, do not use Rockwool, as Rockwool cannot withstand the temperatures that the combustion box and riser can reach. Instead use Ceramic Fiber Mat Insulation which can withstand temperatures up to 1200 degrees celsius (= 2192 degrees Farenheit). And do not use metal for the combustion chamber and the lower part of the riser. Use insulating ceramic stones instead / or Vermiculite plate (Listen to Loz Harrop, who tells You about what you should expect, including limitations, when You use them). It would be desirable to lead the gases from the pyrolysis container down, via a pipe, into the combustion chamber or the lower part of the riser. How this is best done, I currently do not have any good advice. The only thing I would like to mention is that the pipe with the gases from the pyrolysis container should be terminated so that you can see this from the outside while there is still fire in the combustion chamber, so that you can assess when the pyrolysis process is over. This reveals a need for a refractory glass at the end (the beginning) of the combustion chamber. So why not place a small hatch with glass and air damper at the end of the combustion chamber. And then a lid is added over the pellet hopper so that the air supply can be controlled. You do not need a fan - If you do not have enough draft in the Rocket, add length (height) to the chimney and keep the chimney isolated. Insulate all parts including the pyrolysis container == For those that is new to rockets or in lack of knowledge about rocket technologi, the following sources are worth visiting: #) Web-site: batchrocket.eu/en This website presents you with Peter van den Berg's knowledge and experience regarding Batch Box Rocket Mass Heaters. #) TH-cam channel: Loz Harrop Loz Harrop has collected his knowledge about Rocket Heater during severals years of qualified experience. == Temperature Measurement: During development of this charcoal production unit, it may be desirable to be able to measure temperatures in different places of "the rocket". For this purpose I imagine that type K temperature sensors will be most suitable, as they (some of them) can be used for temperatures up to 1100 degrees Celsius (= 2012 degrees Farenheit). The reason I mention this about temperature measurement is that it can be a method to determine at what height the pyrolysis container should be placed in the riser. The pyrolysis container must not be placed too low in the riser, as it then becomes too hot, which breaks down the metal tube too quickly, but also not too high, as the contents do not become carbonized. The Temperature Mesurement can be seen as en separate project. It can be made by using an Arduino connected to one or more MAX6675 Thermocouplers. It can be used to measure temperature in the range of 0°C to 1024°C For some years I have been making charcoal for biochar in a pot in my wood-burning stove (boiler), and at one point of time the stainless pot lost its bottom. The bottom contained an aluminum plate, which melted. Aluminum has a melting point of 660 degrees Celsius, so we know that we can easily reach this temperature level and higher in the burn chamber and in the riser. And this is the reason why we should not use metal for the burnchamber and the lower part of the riser. According to Loz Harrop, this is the bottom approx. 30 centimeters of the riser, which should be considered a part that needs to be regularly replaced due to temperature degradation, and therefore should be an independent module.

Close off the part your fire cage is in and only allow the air to inter from it with a lid to control the air flow

Interesting build. I have been looking at doing something similar. If I were given this project to modify I would do the following: Make the basket full size. This gives you the option of using things other than pellets as well as gives you as much fuel as you need to achieve your heat goals. Intake air from the front with air control (at least until you figure out what size works best then you can remove the extra weight/moving parts). Add pipes in the bottom going from the front to the secondary burn area with ability to close them off, you only need them open when it is hot enough to have secondary burn. Insulate insulate insulate. Add a fan to the mix for getting up to pyrolysis temperature. I read that you want to keep it portable. I think a 12V tool battery would last long enough on a 12V blower type fan to get it up to temperature several times. Good Luck

Add a small blower fan

I would suggest wrapping your retort with Kaowool or Rockwool, to start, you need to keep the charcoal feedstock above 451° to gassify. That is a simple and effective step, i look Forward to seeing what happens next. I have a design kicking around in my noodle where you build a rocket stove, using a 15 gallon barrel for the heat bell, that being welded into a removable lid 55 gallon drum that is wrapped in insulation, then venting the exhaust up a secondary stack with a vent line from the charcoal chamber to the intake of the combustion chamber.

And put some metal or rebar to create a hot spot before the flames enter the up pipe

You don't want any air getting in but what's coming in from the feed tube

Just put a baffle in the exhaust pipe to keep more of the flame in the pipe and that will heat it up more and as to get a longer burn make the feed smaller and taller as it will act as a blast furnace

Very cool!

Very cool idea for small batches of charcoal! Merry Christmas

Hi from England, love experimenters, looking to build similar, to utilise small brash to burn on my wood burner. Good vid thanks

I second the recommendation to add insulation. A better next design would be to have the fuel heat the outside of the product chamber.

I think your mistake is not staggering the Spikes. Great job, I'm building this

Nice looking setup there. If the silicon doesn't last try thick oatmeal to seal it. Works for shiners

With just an oil drip, how does it reach temp to achieve pyrolysis?

Chemical resistant gloves need to be worn when handling pesticides a long sleeve shirt and a respirator for the fogging application.

Yep. The tines are too long, spaced much too far apart and they’d be far more efficient if they were pointed spikes.

Thank you very much for making this video. I am interested in making biochar for a small farm, and I was really wondering how a rocket stove would work. Thanks for the real-world data.

you may be geting ash bidup that block the air

try to put the wood feed at a 45 ang and a diveder inside to let air under the fire

Looks like something out of Mad Max 😂 Great job building such a useful tool yourself. 👍

Do you have a part number or link for the mister

I like what you are doing here. I do think you could pack the "oven" tighter without any strong negative effects. Did you have to refill the pellets, or was the initial amount enough? More than the time, the amount of attention required is what would concern me, and it's also the best reason to use pellets over wood.

Wonderful to see. Thank you for sharing your progress.

You can make videos on making biochar. You will get more traffic. We now know where red hot comes from!

Have you ever thought about making Japanese binchotan type charcoal?

Does this attachment only for the Stihl backpack sprayer? Or does it fit a handheld Stihl bg56 blower?
