Abstract
Modified solid fuel manufacturing method and modified solid fuels manufactured using the manufacturing method. When solid fuels are manufactured by crushing low grade coal, mixing the crushed low grade coal with solvent oil to prepare a slurry, heating the slurry to at least the boiling point of water to evaporate moisture included in the slurry, separating the solvent oil from the slurry to produce charcoal dust and compression compacting said charcoal dust, by heating the slurry to at least the boiling point of water, the non-volatile components included in the low grade coal are extracted with the solvent oil, the outer surface of the low grade coal and the internal surfaces of the pores are coated with the extracted non-volatile components, and the content of heavy oil added from the outside will be less than 0.5 mass % relative to the solid fuel after drying.
