[0002] The biomass hot air furnace is a boiler that uses biomass pellets as fuel. Biomass pellet fuel is a granular fuel made from discarded crops such as straw, rice stalks, wood chips and peanut shells through processes such as crushing, mixing, extrusion and drying. Its function is to generate heat energy and then transfer the heat energy or store the heat energy for a short time.
