New to Gasification - Where to start?

Hey Joe,
I just mean that if you have charcoal that makes a lot of fine dust you will have to have a filter big enough to not plug within your desired run time.

Thanks, Chuck, for the insights!
Your comments provoke a couple of questions: Do you shut your generator down at the end of a run, or let it die on its own? How far down does the charcoal level get?

Hey Kent, depends on if I’m around or not, lol! If I’m nearby and hear it start to slow down, I might jostle the gasifier to move the fuel down and get another half hour of run time with a mixture adjustment. Otherwise it can just die.
Don’t put any voltage or frequency sensitive loads on it. Inverter generators might be better for this kind of abuse.
Edit:
About 33 gallons of 1/2 inch minus charcoal are consumed. This is with engine vibration of some sort to aid the flow. Your fuel size will affect how much is useable with an updraft… larger pieces require a longer reduction zone. If you get too small it will run great but plug quickly. Nozzle size will also affect how much fuel is useable. A small high velocity nozzle will have a smaller, hotter, and more efficient reactive zone… but introduce other challenges like slagging, over heating your nozzle, and high vacuum losses for the engine.
