I'm not getting your air-flow logic at all. Well, that makes two of us! (BTW, I just replied to Crispin's note with several links to the Anila stove that you might want to check out.) However, to answer your direct question, my overpowered fan at the bottom on the cylinder blowing fresh cold air through the grate/cone is turning the thing into a real blowtorch, which overheats the biomass in the outer cylinder, creating additional gas, which with enough forced air burns well, with without additional air manages to leave as unburnt stinky tarry smoke! I'm going to fabricate another grate/cone with fewer and smaller holes, and then try it with no fan. (I have a low powered computer cpu fan that I'll keep at hand.) Since you are building a GEK gasifier unit, I'll mention that I have most of the parts assembled for a G3I gasifier, and it uses the same size tube as does my "anila inspired retort"! The G3I stainless steel tube is a bit more than 70mm in diameter (about 3"). The square tube combustion chamber at the bottom of my "anila inspired" stove is 100mm (about 4"). Hopefully, experience with fuel size and fuel type that works well for the stove will help when running the G3I. At what stage of construction are you with the GEK kit? Also, I hope you are building a good stash of charcoal from your Wood Gas Campstove XL to use in starting the GEK. I just dump my stoves glowing char into a stainless steel bucket of water, and then fish the larger hunks out for use as charcoal, and then dump the water with the ash and small pieces of char onto the compost pile. Do you think my stove needs a "swirl burner"?
