Research on the Compression Mechanism of Densified Biomass Fuel
By using mechanical force, biomass can be compressed or extruded into densified solid fuel with higher bulk density and higher calorific value, which makes it convenient in transportation and storage. The compressing technology of biomass is considered as one of the simplest and the most direct way to utilize biomass as a fuel in the world. However, due to the different chemical composition of biomass, the compression mechanism of biomass particles is different from other particles of coal, ceramics, metals and other materials. A comprehensive study on the compression mechanism of densified biomass fuel was carried out in this paper. The effects of the common chemical components of biomass on the quality of the densified fuel were further explored. The purpose of this paper is to provide a theoretical basis and a technical reference to understand the compression mechanism of biomass.
