METHOD FOR MANUFACTURING COAL BRIQUETTES, AND APPARATUS FOR MANUFACTURING SAID COAL BRIQUETTES

摘要

Provided are coal briquettes having superior heat strength and a method for manufacturing same. The method for manufacturing the coal briquettes comprises the steps of: i) providing powdered coal; ii) providing graphite for restraining the degradation of the coal briquettes at a high temperature; iii) providing a curing agent and a binder; iv) mixing the powdered coal, graphite, curing agent and binder so as to provide a mixture; and v) forming the mixture so as to provide a coal briquette. In the step of providing the mixture, the ratio of the amount of graphite to the total amount of the powdered coal and the graphite is greater than 0 and less than or equal to 0.3.
