There are various types of biomass, such as agricultural production waste, forestry waste and flammable biomass can be used as biomass fuels, which are rich in source and easily accessible.
Moreover, the production and processing of biomass forming fuel are convenient, the use and operation are simple, the economic benefits are considerable, and it is harmless and pollution-free. Therefore, the research and promotion of biomass fuel briquetting or pelletizing have great social and economic benefits.
