[0002] Biomass fuel is different from fossil fuel. It mainly burns agricultural and forestry waste, such as straw, sawdust, bagasse, rice husk and other biomass materials as fuel. In addition to its aesthetic value in the earth's ecological environment, biomass is also a convenient and economical renewable energy for humans. When preparing biomass fuel, agricultural and forestry waste needs to be crushed, mixed, extruded, dried and other processes through a biomass fuel preparation device to make it into blocks or granules.
