[0002] By using biomass fuel instead of coal for heating, smoke and other harmful gases generated during the burning of coal can be reduced, and the burning of biomass fuel will not pollute the environment, which is more in line with the concept of environmental protection. Biomass pellets can be made of raw materials such as rice husks, corn husks and peanut husks, which are crushed and compressed to form a clean and beautiful product. Moreover, with the continuous deepening of wood processing and the implementation of the recycling concept, waste wood chips and wood can also be used to make biomass fuel, avoiding the pollution caused by incineration and realizing the reuse of waste.
