Review on physical properties and forming mechanisms of biomass briquettes

In order to improve the quality of biomass briquette and provide the reasonable principles of briquetting process, the physical properties of biomass briquette experiments were carried out and the research trends on biomass briquetting both abroad and at home were discussed. The mechanism of biomass briquetting was analyzed in this paper. Furthermore, the relationships between physical properties of biomass briquette and particle behavior, biochemical characteristics or electrical potential characteristics appearing in the compression process were described. Moreover, the new ideas and process for further in-depth studies of biomass briquetting were presented.
