It is mainly different from fossil fuels. The application of biomass fuel is actually mainly biomass pellet fuel, which is a new type of clean fuel that uses agricultural and forestry waste as raw materials and is made into various shapes (such as blocks, granules, etc.) through processes such as crushing, mixing, extrusion, and drying. It can be directly burned.
