Background

Energy is a material basis for the development and progress of human society, but the increasing exhaustion of fossil fuels such as coal, petroleum, natural gas and the like provides challenges for the survival and development of human beings. Meanwhile, the environmental pollution is increasingly serious due to the large use of fossil fuels. The biomass has the characteristics of environmental friendliness, renewable resources, ideal clean energy and the like, and is widely concerned by governments and scientific workers in various countries. The biomass power generation technology in China, particularly the biomass direct-fired power generation technology, is developed rapidly in recent years.

however, unprocessed biomass has the characteristics of high volatile components, high water content, high content of alkali metals such as chlorine and potassium and the like, and when the water content of the straw exceeds 40%, the biomass is directly used as fuel, so that the biomass is easy to burn and unstable, and the heat efficiency is low. However, although the biomass raw materials in China, such as agricultural and forestry wastes, have huge yield, the production area is dispersed, the energy density is low, the variability along with seasons is strong, the natural drying loss is large, and a large amount of space and large loss are occupied in the storage and transportation processes, so that the biomass is difficult to efficiently clean and utilize. At present, biomass power plants basically have various problems in the processes of fuel production, collection, pretreatment, transportation, storage, transportation and feeding. Therefore, the crop bulk straw can only be used as a primary fuel for biomass energy utilization, and industrial requirements of biomass power generation, heat supply and the like are difficult to meet. The biomass briquette technology provides a solution for the problems of biomass transportation, storage, fire fighting and the like, has a wide development prospect, brings the revolution of fuel energy, and generates great economic and social benefits. The biomass forming operation needs special forming equipment, and the existing forming equipment has simple structure and higher energy consumption and can not meet the forming requirements of various raw materials.
