3 PRINCIPLE OF THE METHOD
Some air-dried solid biomass fuel combustion in the sample amount of oxygen flow to produce water and carbon dioxide, respectively, and two water-absorbing agent
Carbon dioxide absorbed by the absorbent, calculate the content of biomass fuel in accordance with the increment of carbon and hydrogen absorbent quality. Sulfur and chlorine interference carbon determination
Elimination of lead chromate and silver by volume. Nitrogen determination to eliminate the interference of carbon granular manganese dioxide.
