    摘要: A method of producing coal briquette at a low energy cost by saving heating step or drying step for fine coal, which comprises adding and mixing from 1 to 10 mass parts of powdery starch to a coal having 15 mass % or more of water content and comprising 50 mass % or more of particles with grain size of 5 mm or less to form 100 mass parts of a mixture, and coating the surface of the briquette product with 0.1 to 5 mass parts of a heavy oil component simultaneously with or after pressure briquetting the mixture by a double roll briquetting machine in which concaves are formed on the roll surface, as well as coal briquette which is inexpensive and has high strength and high waterproof.
