This point reminds me of something that was not answered some time
ago. I think the soot develops in the secondary flame, burning out
volatiles from the pyrolysis of fresh fuel in the firebed. Other
particulates will be fly ash. I wonder if more turbulent flame
conditions result in more complete burning out of soot but increase
fly ash. Is there any evidence of a change in particulate chemistry
from fan assisted stoves?
