ABSTRACT:
An apparatus for producing solid fuel includes a passage for introducing a supernatant in a mixing tank into a portion between the bottom of the mixing tank and a first slurry pump of a first slurry circulating passage using a third pump, and a passage for introducing a supernatant in an evaporator into a portion between the bottom of the evaporator and a second slurry pump of a second slurry circulating passage using a fourth pump. A method for producing a solid fuel includes introducing a supernatant in a mixing tank into a first slurry circulating passage, for washing a portion where coal deposits, and introducing a supernatant in an evaporator into a second slurry circulating passage, for washing a portion where coal deposits.
