Dear Dean and Stove testers, It seems to me the tests we do are 1) on the biomass going in to the stove and the 2) gases leaving after the secondary and, perhaps, 3) the fuel,ash,char remaining. But talk of optimum gas ratios, temperatures and chemical reactions we write about occur between the primary and secondary where no sampling and testing occurs. This is the area we need to know more about.
So back to the pipe test again! : ) For a stove tester I think an interesting comparison would be the percent volatile fraction (pipe heated to 450c) contained in a biomass compared to the make-up of the gasses after the secondary to see if a comparison can be made. Also; the density of biomass packing (volatile fraction density) in the stove body. This could account for the differences in straw types or position placement in a stove. Perhaps it could answer the question of why one of Richards briquettes works better than another(?) or the differences resulting from corn cobs vs wood chips etc. If we see a comparison we could predict or formulate a blend sure to work.
