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"?
