Biomass energy such as straw and firewood is the main fuel for rural life. Although the use of commodity energy such as coal in rural areas has increased rapidly, biomass energy still occupies an important position. The development of biomass energy technology is of special significance to China's energy structure and environmental improvement. Biomass fuel is a block of environmentally friendly new energy produced by processing straw, rice straw, rice husk, peanut shell, corn cob, oil tea shell, cottonseed shell and "three wastes".
