Top down burning?

[vvvv]

hmmm, I am familiar with these principles. have you seen the "afterburner" (which i think they now call the Fire Dome) that Harman uses? Seems similar to this gasification boiler concept = no tubes, combustion air from the upper front of the stove body, drafting into lower back section, extra air added= clean burn. Had to say stochiometric didn't you? Now I gotta break out the dictionary. S...S....st.....sto....

stoch...= needed amount of air for complete combustion. with woodgas its about 7 parts air to 1 part woodgas, approximately

I've tried the top down burn in a gassifier and usually get a major fire on top and not much fire for the gass chamber. Seems like I have my own little out-o- control fire.
