- In which it makes its debut as a most curious barbecue toy at BEN'S BIG DADTURDAY SAUSAGE FEST. The ladies were not invited but the children and manfolk were duly impressed. Sadly no sausages were cooked on the furnace. What won't we think of next?
After replacing the oil pump before the firing, we experienced yet another failure of the exact same model of pump, which in this case was being used as a water injection pump. This incident led us to experience downright scandalous operating temperatures.
Needless to say I won’t be buying any more of these cheap diaphragm pumps. - วิทยาศาสตร์และเทคโนโลยี
Comming in 2022: twin turbocharged version.
This would be pretty cool, a bigger turbo for a low pressure spool, and the smol boi for the high pressure, maybe an intercooler between them for better efficiency.
@@pvtnewb It has to have an intercooler at the temps they are pushing, and maybe oil cooling as well.
Yes plzz
Yep, it's "coming"
coming in 2023 compound turbo setup 110 into a 190 it’s gonna take a while to spoil but the amount of boost that it’s gonna make your gonna need to mount it into the ground and maybe even to more
Red hot and it didn't explode. GOOD. It makes a very good furnace for the winter. The gauge was dangerously close to the flame. Good job.
Thanks! Yeah the steel is getting thin and I think this burn chamber is basically at end of life.
@@survantjames have you tried to coat it with lipids? any oil or fat works, polimers cannot stand that high temperatures but the blueing shouldnt shave as quickly as the continously rusting steel, while being cheaper and less labour intensive to replace compared to changing the whole burner
@@survantjames try lining the inside with Plastech 85P... It is rated to 3000F and will greatly extend the life of your chambers. You ram it in place and then fire it after it dries. Also, once you get that figured out, try insulating with kaowool to improve efficiency. I wish I was your neighbor, we could do so much!
@@chasbader We just moved, hoping our neighbors will be as enthusiastic as you are! Thanks for the tips. I’ll have to look into that stuff.
The hell it would that's loud ash no way I'd wanna be around that bullshit
Anything that pumps lots of smoke a makes a huge noise is always the best way to get the neighbours edgy, please keep it up
6:52 - A word to the wise, resist the temptation to see how hard that intake is drawing air with your hand, because the difference between "ooh, neat wind!" and "bye fingers" is terrifyingly small. Don't do it!
Awesome project 👌
When the even range safety officer is risking his digits you know it’s a party.
@@survantjames Next video "visit to the ER"
That seems like good way to make friends with your neighbors on a Sunday morning 😅
Increase your water pressure. It needs to be higher than your boost pressure. Otherwise it blows back through the pump. You might also try a check valve to regulate.
The garbage diaphram pump we were using for water failed to self-prime and we didn't notice before getting carried away with the run. There is indeed a checkvalve on the water injection line. Thanks!
that swirl chamber to ensure proper combustion is pretty brilliant. 10/10 I like it.
that's designed as a vortex filter to keep the most egregious material from impinging on the turbine blades but now that you mention it i can't imagine it's not also serving as a secondary combustion chamber
Man, your neighbours must be really pissed off! 🤣
Somebody needs to make a go-kart powered by one of these things
I'm not sure how I stumbled into this video, but I feel like I should be right there beside you guys. What a great video!
This video showed up in my feed of recommendations for mechanical mischief and ... hey, I know those guys! So good to see you guys getting up to some proper fun. Cheers!
Peat! Fancy seeing you here! Hope you are well! Glad you enjoyed the show. :) Cheers!
That thing got some power, i've just discovered your channel and i will immediately go through all of your videos.
Thanks for the comment! Glad you enjoyed!
I run a petrol engine on woodgas, to make power for the farm - and I am really amazed at what you have done here :) .
@Marty Fourre gasified wood. Its an odd process but it chemically breaks down wood by cooking it and it releases combustible gases
@Marty Fourre
Yup. Alex is on target.
Wood is burnt in a low oxygen environment, where is produces highly flammable gases.
This gas is then cooled, cleaned and dried - before being fed into an engine.
You can see examples of this on my channel :) .
Super awesome, Bros!! Add a LOT more water at the cyclone indeed.
This is the first turbo burn barrel I have seen where anyone is smart enough to put a secondary centrifugal debris filter in to keep from blasting crud through the turbo. Well done guys!
Put a muffler on it and you've got a really cool steam punk outdoor area heater. Way better than a "fire feature"!
It's impressive to see something simultaneously as useless as it is dangerous... well done gents.
Sick video boys! Absolute pleasure meeting you guys at the gambler! ABG
Great to meet you guys too! Happy gambling!
hail motor
Good to see y'all wearing hearing protection unlike every other one of these I've seen. gg
Ha, good point. Yeah they are absolutely deafening!
Nice addition with the boost referenced pressure regulator.
perfect for those cold winter nights
Dam that's some heat!!!...good job boys 👍
Just ran upon this cool channel that’s ballsy y’all
This technology has great untapped potential. Youse guys and Bobby Mcboost are the only ones I've seen do this since a shop in Canada about 10 years ago.
I agree! TH-cam is suddenly blowing up with these things. I’m sure we are gonna see some wild stuff in the next year.
Excellent video.
Videos like this is why my sleep is jacked up
I have been watching videos like this all morning I really wish that i had an old turbo to build one with :(
Junkyards are wonderful things
@@jamesburleson1916 that they are :)
They're also cheap on ebay.
Have you considered re-directing the air from the pre combustion area to the post combustion area to keep the egt's down, get a more complete combustion, and maybe a form of boost control? I was thinking maybe just a wastegate from the boost pipe off the turbo to just before your cyclone filter. Curious to see what you come up with next...
Yes, we eventually plan to make an affordance to allow air leaving the compressor to bypass the combustion chamber in order to reduce turbine inlet temperatures.
Redirecting some of the air from "primary" zone to the "secondary", would help with more complete combustion, sure. However it'll make the final product more "lean", which I guess will rise egt's even more. However, of course, the total energy output will rise.
@@NuViss This. You'll burn the smoke from primary combustion adding more heat to the mix if left as is.
However, the more air goes to the secondary chamber over the primary, the cleaner the exhaust will be. Air in the primary chamber should be just enough to light off the fuel, with the rest going to the secondary chamber until smoke output is effectively zero. Watch how an orchard heater (AKA smudgepot) or EPA-certified wood stove works. Bonus is the fuel will last a lot longer.
Starting will be an issue, however, since you need to heat above the smoke's flash point to get the secondary burning process going, so some way to divert between the two will be necessary to adjust as the whole bomb, err, turbofurnace heats up. :)
Supply compressor bleed air into the nozzle for an afterburner @@survantjames
LOL "You wan to put that out" LOL
What a cool build. Respect for all the engineering and design that went into this.
Two things I noticed:
The filter "trap" looks the hottest of all the components. Am I correct to assume that charcoal is causing that?
Also, it seems like water injection doesn't just lower combustion temps, but also controls the smoke. Maybe you could play around with a multi-point injection, say, another port in the filter just before the up pipe.
It'd be cool to see this thing with a water jacket, and maybe a catalyst for even more heat!
I’m not really sure what causes the bottom / trap of the filter to get so hot! Maybe the long residence time of gasses that make it down there? Maybe the fact that the soot dust that ends up swirling around there in large concentrations imparts a lot of heat to the sides? I’d be interested in reading some papers about heat transfer in cyclones….
Re water injection: yes, it does reduce the smoke, good observation! Actually I am planning to add another injection point exactly where you suggested, basically coming up through the filter trap bottom and spraying directly into the up pipe! I’m very interested to see if it will calm those TIT and EGT numbers down!
Can I suggest that you are only getting partial combustion because you are introducing the fresh air below the wood instead of above the wood and you are running rich by blowing the unburnt charcoal/smoke up without secondary air to burn it.
@@brucebaxter6923 Yep that's definitely happening.
another commenter suggested the vortex filter is actually serving as a second high swirl combustion chamber. the turbo furnace is a ruminant!
Cool idea about the water jacket. Might help keep things from burning to oblivion so quickly.
That's quite a contraption there!
It's only a matter of time before you see someone build a quad turbo furnace on a much larger scale.
Or say a turbocharged steam engine locomotive.
Check out Nikola Tesla’s improved combustion + steam turbine patent GB 186,083. It’s pretty much what you’re explaining. He patented it, and a few other improvements patents for the turbine, in 1921 10 years after the original and about of a decade of R&D.
Have you put a digital thermometer on that to see how hot its getting? Thats unreal! Love it!
EGTs top out in the range of 1200-1300F
Could you make a video of all the improvements for the brunner ???
I've watched a few of your videos and that thing is awesome! Awesome enough to be its own end goal, but I get the impression (mostly just from the effort you've put in) that you're working toward some higher goal. If that's the case, what is it? Are you going to find a way to harness the power from it? Some kind of generator?
All I can say is: stay tuned. :) Next video we will definitely be extracting some amount of work from it.
Ok then, subscribed!
@@charlesstaton8104 Thanks!
7:20 WOOOOW!
Out of all of these things that I have seen this one is probably the coolest I love the Dyson style dust collector thing to help prolong the life of the Turbo especially how red hot it gets that things actually an efficient furnace yes besides having to wait for it to shut down to reload every time it's pretty damn cool
YEP the 2 stage on the exhaust was a good idea
Letting these things destroy turbos is easy, controlling them is the hard part.
a beast
This helps the environment 👍 is what people would be told if I was there
Use an injector with a small pwm controller to set the flow exactly . Man what a monster 👹 great job!
Thanks!
Love that orange color 🍊
Using the cyclone to keep debris out of the turbo is awesome.
Cool project. First time viewer, and genuinely curious what is the point? Yall just havin fun makin fire?
Whats the benefit of the multiple combustion chambers?
It's a stationary fuel to noise converter.
Now that one will heat up your shop pretty quick 😅
Such a cool build, can't wait for a new version.
I think as others have said, a blow off valve from the charge pipe to the up-pipe to cool down that turbine might be a good idea. Hopefully enough of the fuel is combusted by the vortex chamber to not raise EGT's even higher.
Something like that is definitely gonna feature in the next build.
Those bosch style pumps are good for 75psi, real monsters.
Something like this with a water jacket and used ad a boiler would probably be a small form factor way to make hot water. Though I highly doubt it would be efficient
Words put together. EXCELLENT. Makes very good housefire. Paper made of wood. Words as salad.
Eating blue takis while watching this is a 4D experience
Excellent work very interested to see what effect the water injection has on the TIT
It definitely has an effect. We have been using a thermocouple to measure EGT and adding water definitely changes it, so I imagine TIT does also. In the future I will definitely be adding a TIT probe.
I would love to see this driving something.
No woman would ever make such an entertaining contraption !!
Sound delicious
If you point the blower down, it might work well for snow removal this winter
How fast do you think you could heat a pool of water with that? Like submerge most of the hot bits.
Darwin award nominees. Super heat thin metal to nearly it's melting pount, add some pressure to it by using a turbo charger and place all of this on a homemade wooden furniture dolley. What could go wrong. It is very cool though
thanks! drive fast, take chances!
What is the end goal here? It's really cool
nice vacuum you got there
It's a good thing you didn't get the water going..That's how many steam boiler explosions happen..Secind only to faulty pressure relief valves...Water level sensor goes out and eventually there's a delay in the water entering...Flash steam..Kaboom
They did get the water injection going. Not really fair to compare a boiler and this.
Hell to the yeah!
Dope! What was causing it to cut down periodically/lose psi? Would love to see more!
We have a throttle valve in place limiting intake air flow to keep it from running away. Operators are instructed to keep it steady around 5psi and not to exceed 10. Once we can get exhaust temperatures reliably under control we hope to achieve higher operating pressures. Stay tuned!
@@survantjames very nice, excited to see more!
@@survantjames You should install a bigass wastegate on the turbine inlet (hot side) to regulate the boost pressure automatically. I wonder if you could do some water mist injection somewhere on the hot side to keep temps under control without losing thrust, since the heat would cause the water to flash to steam.
@@draggonhedd Yep, we do have water injection already. The pump failed to prime and that’s why we stopped and restarted.
@@survantjames oh i thought that was water cooling for the turbo core
Safety is number one priority.....
How much thrust does this make?
I am developing a turbo reactor based on oil and water with the pressure of the same turbo including for the lubrication of the axle. my question is ... did you try injecting used oil into the reactor other than wood and water?
Not yet! ;)
pretty sure that's just a shitty jet engine
@@survantjames you should use the injector nozzle apparatus that's inside those diesel/kerosene jet heaters. It has 2 ports on it one for compressed air and the other is for fuel. The more air pressure you give it the more fuel that's atomized and injected. Would be perfect for this.
Was really hoping for a "Stttuutututu"

Strangely, there are 3 of these videos on my recommended list now. I wonder if this is connected to the impending freeze of europe this year?
Bright orange
My brain : LICK IT
I see near melting heat on the bottom pipes there, it will become structurally instable with only a few more degrees heat.
Someone's going to get badly burnt, flame with plenty of velocity and molten metal will remove limbs/eyes faster than you can get out of the way
You dudes are playing with fire.
Confirmed!
it's a hell's machine
Hi. I'm about to build a turbo furnace myself. I've got a couple of questions.
Would you say that the cyclone filter is an necessity for longevitity of the turbo? Or would a finer mesh screen in the burn chamber do?
Could you go for a bit smaller burn chamber or is your chamber the smallest you should run with if the turbo is in that size?
Regards
Most of the material we've caught in the bottom of the filter is basically soot. Occasionally there are larger chunks of charcoal. A fine stainless mesh screen (with lots of surface area relative to the turbine inlet area) might be totally adequate!
You could probably go for a smaller burn chamber, but I personally would go bigger next time. This one only burns for about 5 minutes fully loaded with finely chopped wood.
A word to the wise: the door has definitely been the biggest engineering challenge.
Good luck! Interested to see what you come up with. Drop us a note if you post a build / firing video!
@@survantjames thanks for the answer, much appreciated. I will go for the stainless mesh, I plan to make the chamber out of stainless as well.
Oh I see, had no idea that this size only gave about 5 minutes, will defenetly go bigger.
Yeah, I've actually been thinking about the door alot, do you have any videos or pictures posted on how you did it? Never seen a door on a turbo furnace been fully sealed, it almost always leak a little bit.
I will post a video when it's running!
@@momatedise Our "Idol of Motor" video goes into detail about the door. It sealed pretty good for a dozen or so cycles, until recently where it seems to be a bit warped. Good luck!
@@survantjames Have you considered a total loss oiling system that used waste oil both for turbo lubrication and then injecting that oil for fuel to increase burn times? Maybe goes against the spirit for a wood powered turbo.
Idk what the fuck this is but I'm digging it.
Awesome work guys. I’m in the planning stages of building something very similar and been scouring for videos of it done properly. This looks awesome. From the cooled lubrication oil, to the throttling it properly. What are you using to throttle it? I was thinking a large throttle body with a push pull cable to control the intake flow.
One more question. What is your cooling water cooling? Are you spraying it in just before the “cyclone”?
Oops one more. Does the discharge tube on the cyclone protrude down inside it or just butted up and sitting flush with the top?
Cheers
Hey there! I'm the one in red
We're just using an off the shelf throttle body with a pull cable on a foot pedal
In this iteration the cooling water is injected straight into the burn chamber and keeps the exhaust gas cool enough not to melt itself. Later we added another jet straight up into the cyclone.
There's a spreadsheet with the specific cyclone geometry, I remember it coming down about 4", half way to the conical section
@@specific-solutions awesome thanks for your reply. I’ll be building one in the coming months. I have a large turbo and weld up a couple of chamber, one for a fire box and one for a cyclone I’ll go heavy with mine, maybe 1/4 wall minimum to try and make it durable. This is an awesome project and can’t wait to have a go at my own.
@@ttv8ra23 you might try to play around with refractory materials. Would mean less parasitic loses, no metal oxidation, and less intense temperature swings for the metal. But you will probably have to be careful about how you spray water in the system. And if a chunk somehow comes off, it's gonna find it's way into the turbo.
@@specific-solutions thank you for your reply. I am planning on running a 60mm wastegate as well as a throttle plate to control it. The wastegate is a water cooled one and I plan on water jacketing the short pipe from combustion chamber to wastegate, that should Pre heat the water a bit. I was thinking of maybe injecting the water where you did in the burn chamber and then maybe inject it into the cyclone right where the pipe from the burn chamber enters, my thinking is that way the water would be swirled within the cyclone giving it lots of time to superheat and dry. Thanks again for the reply. Love ya work.
@@specific-solutions A wastegate actuator tied to that butterfly valve would be the bees knees to make this run steady without human input.
I wonder if you could melt glass with that torch coming out the end
"stutututu noises intensify*
The tree directly behind that existed is like. TURN IT OFF !!!!!!!!!!!!
What is this thing for??? Looks dope
bobby mcboost in austraila did one with wood and an air compressor tank. his was rather sketchy though
There's still a bit of smoke coming out of the hot end. Do you think putting some holes in the exhaust tube would suck some fresh air into it that would mix with the unburnt fuel and turn it into a sort of afterburner?
I have considered this, definitely something I'd like to try at some point. Might need to get a little creative with the geometry so that the exhaust gasses actually entrain outside air into the exhaust tube; I think if we just drilled holes the smoky exhaust gasses would just come out of those holes. I've also considered bypassing some of the compressed intake air and re-injecting it into the exhaust plume after the turbo.
@@survantjames I think it would only need a small tube that has it's open end inside the exhaust facing the exit of exhaust so the flow pulls a vacuum as it rushed past. That should get a little air coming in
@@greenbassboosts8872 yep that’s about what i imagined as well
@@survantjames I dont think drilling holes would work, but maybe thin slots you could use a small screwdriver to insert into & bend the slots to face outwards on a conical exhaust shape out to a wider area where it flattens out to reduce pressure & add external air from the conical section, this is something like how the military do it for afterburners, but they do add air from the compressor bypass air into this section, & fuel of course. This will give a yellowish flame, to make it blue they reduce the exhaust output aperture again after this burn tube area, to RE- compress the gasses as they leave.
You are right, you need to get a little more creative with the exhaust geometry if you want to get a good afterburn, but this thing is awesome, there are always other/extra tweaks. It’s an old thread, but if you haven’t already, check out after-burner tech for a better insight of the maths to make it work.
Good job, Sub’d. Cheers

Believe it or not people have been building these things since the 70’s lol. Glad people are rediscovering ways to be cantankerous 😂
Goooooooooood
That’s scary how hot it gets.
Is this some type of gasifier or just a turbocharged burner
very impressive--but wear your safety glasses
I don't think people realize just how dicey these turbo wood burners are. Hot pressurized vessels are not known for their strength.
What is it melting or heating?
Totally Mad but I Like this video 200%
more p.p.e, please!!
Absolute insanity
HOW IT WORK?!
I’ve never seen anything like this - what exactly are you doing and why?
So what is the end goal of this device?
i liked
That's awesome .... aren't you a little worried about something melting out and creating a bigger fire? And do you have a fire extinguisher close by
Yep, we did have a fire extinguisher on hand! And yeah, the mild steel this thing is made of has seen better days-the intense heat and gas flux causes aggressive oxidization. It's definitely reaching the end of it's safe lifespan now.
@@survantjames it definitely looks entirely too much fun that's what makes it so dangerous and fun LOL stay safe and don't get hurt with that but I'm going to keep watching the videos
safety third
@@milothereporter hi... I am an Ozzie living in Asia, and have a real world application where you could build an sell 1000's of these with some mods - would love to talk to you guys.
add water before turbo return feed and make it 300 times more efficient :D
At least one of ya is smart enough to wear safety googles. Perhaps the others are putting in for Darwin awards.
