[Stoves] TLUD and biochar production

[Frank Shields]

Dear Stovers,

It seems that a TLUD would make poor quality biochar. There are only two hot
spots. One is the flame front and the second the flame heating the pot. As
the flame front migrates down through new biomass volatiles come off and hit
cooler conditions above in the left over char where I would think
condensation of organics would occur. This is good as a cleaner gas goes up
to the secondary air to combust and heat the pot. But the char is left with
tars. This could be better for used as charcoal for other cooking but would
make very poor biochar for the garden - if this is what happens. 

Regards

Frank
