The solid residues extracted from the rice husk biological focal can be mixed with the clay and other additives to press into biomass briquette. In this paper, defined the best molding ratio of the biomass briquette, and investigated the combustion properties. In addition, compared the biomass briquette with the conventional briquette, indicated that, the biomass briquette can substitute for the conventional briquette to a certain degree, and has important significance of environmental, economic and society.
