In a method for producing residue coal according to the present invention, a solvent is separated by evaporation from a solid material concentrate, which has been separated in a gravity settling vessel (7), in a solvent separator (10), thereby producing a residue coal mixture in which the solvent is remained in the residue coal. Subsequently, the remaining solvent is separated by evaporation from the residue coal mixture in a drier (11), thereby producing the residue coal. In the drier (11), the remaining solvent is separated by evaporation from the residue coal mixture utilizing a heat the residue coal mixture itself has. In this manner, an apparatus for drying the residue coal mixture can be simplified, and the cost required for the drying can be reduced. |
