I know you probably like the big plumes of black smoke but I really want to see you build an afterburner to ignite all that unburnt fuel and shoot massive flames out the top!
Much less fuel burned in that than in a typical house fire or forest fire. On a relative scale of things, a small burn due to the small amount of fuel. Yes, the burn is at a rapid rate and the result is quite impressive.
Hunter, I seen your oil seals were leaking on the turbo's. My brother had a tri compound turbo,super stock pulling tractor. We found out the return oil lines need to be 3 times bigger than the supply line,to keep from blowing up the oil seals!!!
120Psi is above 7 bar..... even that tank can be an issue around that pressure, when it's red hot. Just stay at least 20m away, and more far away from the turbo exhaust, if that take's off, it has more energy than a grenade.
This basically a jet engine; a compressor up front, a combustion chamber followed by a turbine. Instead of a train turbo, use a small jet engine. A couple things I'd like to see. A tachometer on the turbo and a couple thermocouples. Try moving the oil barrel further away with a radiator on top to cool the oil. Gravity feed should do ok. Also you might try using some kind of air dispersion system in the tank to the fire to burn more evenly. You always have a red hot spot right at the air inlet but still cool at the top. Plus fire suits. Great videos, really enjoy them, but be safe. I want you making them for quite a while longer.
They need byass air just like a real turbine. Keep the egt In the safe zone. Im sorta planning out a twin walled setup. Some work on the combustion chamber and air mix... Wood is hard, so much variation from start to end. Really need a gasifier, so its just woodgas, not ash... Get the air hot enough, the fire can be external. Theres a video of someone pulling it off. In Portuguese i think.
So happy to see these still coming out. There is an aussie channel using a Haltech ECU to control a wastegate to keep boost under control. Another strapped theirs to a boat after they fit a wastegate to it. Keep it up!
Maybe adding a fresh compressed air line inlet to the hot tank on a ball valve further away could help maintain the balance. Seems fighting fireballs up top are less than ideal.
@Spudro Spadre fire absolutely LOVES oxygen, let alone compressed air. I didn't see he said ball valve, just make sure there's some sort of flash arrestor.
@@jaybomb5022 Yes fire loves oxygen and the turbos are already pushing compressed air into the barrel so running a compressed air line is not really any different, the fire wont go into the compressed air line as there is no fuel in there and the barrel pressure would have to be higher than the compressed air line's pressure. And if the compressor shuts down or something, worst case scenario is the rubber hose melting.
i mean, there is water injection systems... cant remember the full aplication but the theory being if you inject straight water into the conbustion chamber then it will cool the chamber AND add more pressure to the system
@@djaydeved absolutely, in a old school steam engine, this was called a nightmare scenario, causing extreme heat, an coal burn runaway(very high explosive potential) , but if the water jacket can support an supply end cooling and steam, this thing should scream fer a few hours
@@BurchellAtTheWharf In turbine engines water injection is used to cool the combustion liner, high pressure turbine and low pressure turbine components when desired effect is going over 100% thrust. There's a video by mentour pilot about a 747 in Greece that explains the water injection system pretty well.
More. Bigger. PLEASE. This is the content I wait for from any YT'er. And you're currently leading the builds. I love this so much and don't know why. I know how HP is made. But this is so un-necessary, yet so satisfying.
I believe the turbos get too much heat being mounted on top with fire blowing straight into them. Mount them down low, and have a long enough hot pipe for the gas to cool off a little bit before reaching the turbos. Would be easier and safer to operate also.
@@thedancingpickle6362 yeah I just don't think most turbos are designed for 110 psi and probably around 2000°F EGTs... Likely why the aluminum impeller wheel melted away.
I’m guessing 300lb to maybe 1000 lb force of thrust. Just based on the amount of pressure and the fact that only a single stage turbine is blocking the exhaust so a good portion of that 110 psi is just moving air through the exhaust.
What you're building is not pointless it's basically a Velox boiler, a type of boiler that is turbocharged and was used in a some naval applications due to higher power density. It's what powers for example the kuznetsov and Sovremenny classes of the Soviet/Russian navy. If anything it would be more interesting to run those things straight of an oil injection system instead of wood, so you can control them better.
You should bypass some of the fresh air from the compressor side of the turbo directly into the hot exhaust gas before it enters the turbine side of the turbo to burn the unburnt fuel gases and to keep the temperature of the turbo low enough to make it last for a very long time. That is basically also how real jet engines keep the turbines from melting. The bypass valve can also be used to throttle the turbo. If there is enough fresh air in the exhaust gas you can inject some of the fuel rich exhaust gas after the turbo to build an afterburner.
+1 to keeping the max temp down with bypass, for a longer video. If water injection to the intakes happens too at max temp, that will help the turbos last much longer. Less smoke will mean less of a buzz, but hey, if it means more of those blue flames!
I think turbo burn barrels are super cool, seeing Bobby Mcboost make one with a little turbo was amazing that thing lit off like jet engine but you can do it all by burning wood, all the oil just creates lots of smoke and pollution, what gets it going so well is the wood gas igniting from super heated wood, it burns very fast and efficiently, the oil wont help the wood gas get going
Probably around 100,000 to 130,000 rpm. Turbos this size kinda max out around that. Much faster and they go boom. A smaller turbo will spin a lot faster but wont be able to move as much air due to the size
Doesn’t matter what type of cooling or oil system you add to those turbos. You were so far outside of the surge line for the compressor and turbine maps that the surging caused them to explode. If you want this to be something that will live under these conditions you need to figure out the air flow and pressure ratios for both sides of the turbo and spec them to run under the surge line for the compressor and turbine maps. Then it will live at 110+ lbs of boost pressure and you can then focus on cooling and lubrication.
I will quite enjoy the Loco Turbo Barrel I quite enjoyed this Maybe try a more remote turbo setup, so the exhaust can cool more before it gets to the snail?
why think did at night cover up what add to air and smoke just cloud burn oil look like why world going down drain because idiots can't wait all oil gone we breath better air.
I got the old turbo that was taken out of the moon when they stopped it from rotatating. You could use but I don't want to be part of seeing you die 😂. Good luck on the train turbo
Sickest burn barrel video I’ve seen. I watched the first video and then the second one of you building this one and that thing was EATING. Can’t wait for the next video this rocks !!!!!!!!
Epic fun! Loved the high five at the end. For more safety, I would consider fire suits, like racing overalls or full-on firefighter silver suits if you can get them. Go for it! :D
The amount of natty lights that must've gone into the planning, production and implementation of this project must be single handedly keeping Anheuser-Busch afloat
Consider rebuilding it as a compound compressor setup. you could use one high-pressure compressor, and two more feedings as atmospheric compressors. granted you're going to need to regulate that to keep the combustion chamber pressures in check.
Helll Yea!!!! 110 pounds of boost is where its at!!!!! Should build a crazy turbo-jet engine and then you could have some thrust to play with. Keep it up!!!!
I work at a jet fuel storage facility for an airport. When we have any kind of contaminated fuel it gets sumped off and put into the sump tank. We then wind up selling that as waste when it starts to get full. This oil is basically just off spec jet fuel. See if there is a local airport fuel storage facility nearby that will sell you some of their sump fuel.
You're halfway to a Velox boiler. Just need to add a water jacket and a steam turbine. I think the key is using a much larger turbo, that will help prevent overspeeding.
How about big coal briquetts. Germany has Rekord style coal briquetts which are the size of freight train brake pads. Don't know if you have such big briquetts in the US but these definetly won't be sucked into the turbo and will give you a ton of energy
Dont think having 2 turbos feeding into one was a good idea, seems like the presure was causing them to stall. Perhaps stick to feeding one into another. As for cooling them perhaps a water sprayer into the intake of the turbo? Might decrease air temp and I know it sound counter intuitive to be spraying water into it but it might make it burn better.
1:36 I dont think the oil in the aluminum bottles will stay there until the aluminum melts. The heat will cause the oil to expand and burst the aluminum container before the aluminum melts. Also aluminum oxide will most likely be produced first which increases the melting point. Aluminum oxide melts at 3762 degree Farenheit or 2000 degrees Celsius. Cool littlemtoy. I would love to build one if I had a place to use it. .
How about used cooking oil, adding about 3 transmission radiators, 2 on the return from the turbos and one on the supply for the turbos, some high flow fans on the radiators, a metal drum instead of a plastic drum for the oil reservoir; safe if it ignites, a remote controlled valve to close the intake if it gets out of control, don't forget to get many ABC fire extinguishers, ABC extinguishers kill oil/petroleum, wood, electrical, etc fires. Maybe the turbos need premium ceramic thrust bearings do the high boost pressure. They also make electric waste gate so you can relieve the pressure if gets too high.
Take inspiration from jet engine design and sleeve the inside of the barrel with holes that pipe the cold air into the area between the outer tank and the internal sleeve to keep it cool and keep fresh air mixing with the fuel source throughout. As for your beer can oil idea, you're blowing out the caps well before the aluminum melts introducing oil much sooner. Consider a stainless style tank design that uses the expanding vapor in the oil to feed it out via a tube on the bottom with a diesel style injector to atomize it. Something like this may be needed with the giant loco turbo if you can source one.
This is really cool. I like it a lot. But you guys are really taking chances, you really don't want to be too close to it. I don't know if some kind of bleve is possible with this thing, but if it is, and if it happens you will be toasted.
I think a switchable Nitrous feed on intake to really super charge it. Plus a vertical Afterburner to ignite the exhaust. it'll look wicked. Coal in the base would be great as a dense fuel that will take off as temp and pressure increase. Some sort of fuel injector to allow controlled feed of oil, rather than dumping bottles inside might let you push it harder under control.
Please watch some exploding air compressor videos, they're in the neighborhood of 110psi too. Maybe consider some shielding around the tank in case it pops.
