Method for reforming solid fuel

摘要

Provided is a method for reforming solid fuel, with which it is possible to reduce the percentage of molten liquid in ash and prevent deposition of ash on a boiler. Starting coal and starting oil are fed to a mixing part (11) and mixed, and additives comprising at least one of a magnesium compound and an aluminum compound are fed to the mixing part (11) and added to the mixture in the mixing part (11) to form a starting slurry. The starting slurry is then fed to a heating part (12) and heated. The heated starting slurry is then fed to a solid-liquid separating part (13) and subjected to solid-liquid separation. The solid content that has been separated from the liquid content is passed to a molding part (14), dried, and extracted as product coal.
