Abstract
A method of manufacturing a molded solid fuel including: a pulverization for pulverizing low-grade coal; a mixing for obtaining a slurry by mixing the pulverized low-grade coal and a solvent oil; a dehydration for obtaining a dehydrated slurry by heating and dehydrating the slurry; a solid-liquid separation for obtaining a cake by separating the solvent oil from the dehydrated slurry; a drying for obtaining powdery modified coal by heating the cake and further separating the solvent oil from the cake; and a molding for pressurizing and molding the powdery modified coal by using a molding machine, without the addition/mixture of a binder. In the molding, a coolant is sprayed onto the surface of the molding machine, and the surface temperature of the molding machine is kept equal to or below 100° C.
