- In which it does useful work. For some definition of useful work. In any case, MOTOR was pleased.
The truth is this thing is a much better gas generator than it is a thrust engine. We'll be proceeding accordingly. Eventually. - วิทยาศาสตร์และเทคโนโลยี
Food for thought: There are plenty of CNC channels on TH-cam and only one turbofurnace channel. If your goal is to build your channel then I think you're making a mistake by giving up on the furnace at this point. But if your goal is to pursue projects you're more interested in, then I respect your prerogative. I (and likely most others) just probably won't be all that interested in following along. I think there is a lot of potential in your furnace and I would be interested in seeing its true power harnessed by steam or other methods. Direct thrust from the exhaust is predictably weak but there is so much power available there begging to be harnessed in a better way. It's tragic to see you walk away from it now.
Don’t worry, not planning to make a CNC channel. I don’t think you’ll be disappointed with what we are working on next. It’s a long quest, but it will be applicable to the furnace. Thanks for your comment and stay tuned!
@@survantjames Thank god you won't be giving up on this thing. Never knew about turbo furnaces before your channel and have been super interested in your project since I discovered it yesterday.
@@kylearnold1688 The last 6 months have been real busy with other life projects and homeostasis type stuff. But there’s more to come. Glad you’ve enjoyed! Stay tuned.
As a Airframe & Powerplant mechanic of 23 years and someone who's built miniature gas turbines for rc aircraft at home I have to say I'm impressed!
Its interesting to see you experiment with water injection at various locations in the system. 🙂🇦🇺
I'll bet your neighborhood likes you 👍
half of them come over for the children's birthday parties, 45% appreciate that we're the most visible thing in the neighborhood and thank us for running cover with buckets of cherries and peaches all summer, and 5% call the cops who already think we're pretty cool
I sure do love when my neighbor fires up his firewood bicycle in the night
That is pretty funny stuff guy’s, your neighbours must love you, I thought the tyres might catch fire first before the door blew. Good job & hats off to ya for trying, but dont stop yet, ya nearly there.
Your door need a re-do, it could be smaller, but a big issue I see there, is that the overlocking catches you are using are pulling most of there force to the outsides, against each other, & not down onto the sealing surface.
There are probably a number of other ways to get some real work & power from this contraption, but thrust is probably the least useful, albeit a lot of fun to play with though.
Anyhow, I like ur Turbofurnace creations, so dont stop yet. TFS. Cheers.
If thrust is the goal, instead of throttling the intake, wouldn't it be better to have a controllable "waste gate" to send excess pressure out the back, bypassing the turbine?
Most jet turbines are fuel regulated, this has ample fuel and will run away if you don't throttle the inlet air.
They should route some of the first stage inlet air into the hot side of the turbine, ie, as a bypass, which will bring exhaust turbine pressures up, while lowering the temperature of the exhaust turbine. This needs to be variable as the amount of bypass air must be tuned on a turbojet.
Water injection is a noble goal, but, as you can see in the video, metering the water input is difficult, and will require a needle valve with high enough precision to get right, and a pressurized water system with a bypass before the valve to keep the water pump from failing.
@@jttech44 JT you could definitely throttle via a waste gate, just would need a big one.
JT gets it.
Greetings from Italy - that's the craziest pizza oven I've ever seen,
mamma mia! That being said...binge watched your videos since yesterday
and not regretting it. Fantastic work guys...try and error, layman's
engineering at it's best.
Thanks for watching, glad you enjoyed! Cheers!
It is a wonder you haven't got the government involved to give you a huge loan or grant to assist in your venture for alternative energy.. I mean what could go wrong cruising around thought the dry forest with that thing.. Great editing and thanks for the video .. keep on keeping on boost away
the government has been involved insofar as the cops showed up but they were duly impressed and merely informed us that my neighbors were less than pleased
This is honestly epic.
May the face of MOTOR smile upon you.
If you want ideas for the door, look at aviation for examples. If you can make a 'plug door' that has a wider lip on the inside, it pushes itself shut when there is more pressure in the chamber. All airliners have them because their cabins are pressurized compared to the outside air at altitude.
Love this idea.
What about a two chamber combustion design whereby compressed air is diverted to two combustion chambers. The primary serves to gasify the wood and preheat the combustion air for the secondary. The secondary chamber serves to complete the combustion of the available fuel gas ( for a clean burn) and to temper the exhaust gas leading to the turbine and to control the turbine inlet temperatures to below 750 deg C
By modulating( butterfly valves) the airflow split between the two chambers some control will be gained from the current run away boost and temperatures.
After the hot gas generation process is under control the next steps would be to harness the energy with a " Free turbine" driving a generator or transmission, similar to a turbo prop or helicopter turbo shaft engine or industrial turbo generator
Jerry rigging a surplus turbo prop or helicopter turbine engine to run off wood waste would be the ultimate !
We have considered a gasifier design… it might come i a later iteration. Definitely gonna use a butter fly valve to modulate flow around the combustion chamber in the future to keep TIT reasonable, but probably won't go for the gasifier right away.
Free turbine is also in the design stages.
Thanks for watching!
BURN BARREL TURBOFURNACE EXPLODES!!!
hey look I found out when it stops being a furnace and starts being a jet, its when you mount it to a bike
Nice job guys ! Keep going !!
We have a sawmill and literally tons of waste materials thank I want to utilize for steam power production. A large scale (slightly more tame ) 😆version could be scaled up for the burner and boiler. Really appreciate you guys sharing this. Hope to see a working version soon guys ! Play safe !! 😎
THE TURBOFURNACE IS RUNAWAY!!! September 30 2023
Impressive so far
Have you tried using water to create higher exhaust pressures?
In your next design consider a smaller door. A smaller door means less square inches with pounds of boost stacking up against your latches.
Yep. Someone also suggested a door that presses against its seals as the internal pressure increases, which is also a great idea.
Woah! Huge respect for the effort.
You said you have another turbo just laying around, and plenty of spare boot in the chamber?
Well...
Maybe add that turbo as well, and feeding both the cold side and the exhaust into the afterburner?
You probably have plenty of wood gas and producer gas left in the exhaust just ready for combustion.
Maybe a bigger afterburner would du the trick to get use of it all?
I like misting before the turbo to give it more boost from the steam and lower temperature to spare the poor thing from melting.
If temp go to low it might not ignite the gas in the AB tho, which if a problem could be fixed by having a thin bypassing ignition pipe straight into the AB.
No more in -22 you said. Can't wait for -23.
Hail Motor!
The channel Bobby McBoost got an old boat moving using similar thinking in the video:
I made Thrust from Fire Wood! - Turbo Jet
Thanks Glad you enjoyed! We'll be back in 2023.
I love how the floor plate is just casually burning the whole time
The tires are smoking and melting too.
This is awesome.
I've built and flown quite a few model jet engines but never one like this lol.

So, whenever you get back to this project, will you be working on thermal efficiency next? I know they’re called heat engines, but they aren’t supposed to glow yellow hot. That’s kilowatts of energy that physically cannot do useful work in the current design.
Yep!
@@survantjames I’ve been thinking of how that could be done and one idea I’ve had is replacing the throttle body with a bypass valve just after the compressor. It could divert air through cooling channels in the walls of everything that touches the combustion gasses before reintroducing it right upstream of the turbine.
@@kyleeames8229 Yep. This is the purpose that a “flame holder” or “combustor liner” serves in a normal gas turbine.
What about adding a prop to the exhaust to create a turboprop system
Haha just manic mechanical action in the suburbs 😆love it
Yeah, we are that house.
Maybe go with a wood gasification into a turbaned recipitacating piston engine.
Neighbors hate him. Cyclists fear him.
You look like Guyladriel from the Rings of Power.
Could you design the door to open inward so the pressure would hold it shut instead of trying to push it open? Also I'm looking forward to seeing what you get up to next.
You know that’s a pretty dang good idea I hadn’t considered and if / when we attack the problem again I’m probably gonna do exactly that. Thanks!
@@survantjames Look into Metal pressure seals for the combustion chamber door, I use them at work to maintain vacuum of 0.00002 mTorr at 500 degrees Celsius, so I imagine they would work for this application.
we need all the internal clearance possible for our ruggedly hewn fuel sticks
Using coal briquettes would solve this problem. Would be even better if you use gear pumps to feed in coal slurry continuously.
neighbors have to hate you lol. Should be nice and find a better spot to test.
