Use of biomass particles: 1) Feed for livestock in large farms, which is convenient for storage and transportation; 2) Civil heating and domestic energy are clean and pollution-free, and easy to store and transport; 3) industrial boilers and kiln fuels replace coal and gas to solve environmental pollution; 4) It can be used as fuel for gasification power generation and thermal power generation to solve the shutdown problem of small thermal power plants. China is a big energy consuming country, so it is an inevitable choice to adjust the energy structure and use biomass energy. After compression molding, the volume of biomass is greatly reduced, which is more convenient for transportation, storage and use, and solves the key problem of large-scale utilization of biomass. Therefore, the technology and equipment are very suitable for biomass power generation, clean energy transformation of industrial boilers and new cooking fuel in rural areas. It has the following far-reaching significance: 1) replaces coal, thus reducing the consumption of primary energy. 2) Realize carbon cycle and reduce the emission of greenhouse gas carbon dioxide. 3) Increase the added value of agriculture and increase farmers' income. 4) The technology and equipment conform to the national industrial policy and have good economic and social benefits. 1) The development of straw granulation technology plays a key role in the large-scale application of biomass. 2) If the operation method is proper, the granulator can run smoothly and obtain higher output and longer service life. 3) Granulation technology still has a large development space, and experimental research is needed to reduce power consumption and improve output.
