Home Made / Re: Wood Gasification Boiler Build

Looks like a great project.  I'm in the process of building pretty much the same thing.  I had my fire box rolled and i put a flat bottom in it.  I'm going to be using threaded pipe for the air so it can be removed for cleaning or replacement if needed.  What size tubing you using for the exchanger?  I was thinking 2 x .120 for the verts and 1.5 x .120 for the horizontals.  I was originally going to use pipe but all I could find was sch 40 which is a little heavy for efficient heat transfer.  Good idea you have there with the air tube inside a larger one through the water jacket. .  I also am a little confused on the nozzle.  I like the firebrick idea some on here suggested.  Simple and cheap. Keep us posted.
