biomass combustion process | BioEnergy Consult

The hot combustion gases are sometimes used directly for product drying, but more usually they are passed through a heat exchanger to produce hot air, hot water or steam. The combustion efficiency depends primarily on good contact between the oxygen in the air and the biomass fuel.

Glossary - Biomass Energy Resource Center

Furnace: The primary combustion chamber of a biomass burner. The term also refers to warm-air heating appliances. Gasification: The pyrolysis reaction in which heated biomass is converted to combustible gases in the primary combustion zone. Also refers to the conversion of char to combustible gases in the absence of oxygen and to the overall
