I have been thinking about this for sometime.
There is a warning on CC page on TD
website about not using wood in aluminium CC -probably because it
would melt? I have seen several bushbuddy type tin can stove is which
have steel inner aluminium outer. So my idea is that I could put BPL
Ti foil cone inside CC and burn wood inside Ti foil.
There could be another advantage. I have been reading about woodstoves and how they work. There is some very
interesting dicussion MYOG forum.

passive downdraught gassifier woodstoves are not possible//

The flames are formed when unburnt gases are driven off the fuel
upward and reignite when preheated secondary air from the annular
space between the inner and outer walls mixes with these gases to give
renewed combustion. The wood does not give off fumes downward. hot air
does not easily travel downward. I can prove this because in my stove
the outer wall does not start until well above the primary feed holes
which are the only potential path for fuel gases to get into the
annular space as shown in the earlier diagram. I am certain that my
stove, the bushbuddy and the stove on this thread work by upward
gassification and recombustion with preheated secondary air. Either
way they work well.//
BPL Ti foil comes prepunched. Could one placed inside CC, make CC an
upward gassifier in principal? The primary air would enter the inner
(BPL Ti foil) through the prepunched holes via the lower holes in the
outer CC. here it would burn fuel. The secondary air would go up the
annular hole between the 2 walls and go just above the fuel where it
would reignite the smoke. The holes at the top of CC would be exit
holes for exhaust gases and flames.
I contacted Russ at TD but he is busy right now.
I am also in touch with Derek Goffin.
I would love to know what rest of you think. May be we can even see some field trials since so many people here already own a CC.
