Forget using wood, jump straight into using sump oil, you can either gravity feed it into the turbo inlet to atomize it or pump it into the tank under a light pressure, either way its fuel on demand, less fuel less sketchy, more fuel oh fuck run! 🎉 😮 😅 😊
I think I'd fab up a heavy sliding gate in witch slides on the inside of the burner so that more pressure pushes it tighter shut. No bolts to melt out, and the seal will be created and improved with pressure, rather than pressure compromising the seal
Curious if an interior water injector near the spool might cool the exhaust gas enough to prolong the life of the turbo...possibly even baffles to inject the air like the burn section of a jet engine so the high pressure incoming air protects the burn chamber lid.
OK...These things make huge amounts of smoke and loud noises while being prone to violently explosions....Got it. There was once a time when Australians were enthusiastic about using fire in the service of culinary pursuits where the end result was barbequed crustaceans and other examples of great Ozzie food. When did it all go sideways and wrong down there?
What a Ripper! Good job mate, that was a pretty fantastic burn u had there & it kept going. I love it! My guess is that the best placement & configuration for the fire door would be to make a smaller round (even slightly domed) door at the end of the cylinder just behind where ur fresh cooler air is coming into the burner, this will take a lot more pressure & the cooling air entering into the chamber will help to keep the door somewhat cooler as well. A dome shape would give extra strength to the fire door, which may not be necessary if you make the door much smaller, you could even make a heavy duty hinge & have fewer bolts to do up in a circular pattern around the door. There are a lot of things u could do to this wonderful contraption u have built to control it, but WTF, let her rip, you did good, & it makes me proud to be an Aussie. Cheers
