[Stoves] Smoke-free biomass pellet fueled stove

Crispin stated, "As Penn Taylor pointed out, the value can range from about
12 to 33 MJ/kg so the real value is going to vary from test to test."

Crispin,
Were Penn's analyses done on charcoal from a combustion stove or a TLUD? It
seems to cover a range from high ash char to high carbon char. 

Has any sampling and analysis been done on the variability of char quality
from TLUD's?    

I have often wondered how consistent the char is from a TLUD. While the
maximum heat treat temperature (HTT) is probably consistent, the time that
the char is exposed to these temperatures probably varies. Degree of
carbonization, which will determine the LHV, will depend on when the cook
decides to quench the char.
