Abstract
A coal reforming apparatus includes: a dryer body and the like provided to dry low-quality coal; a pyrolysis body which pyrolyzes the dried coal thus dried, and the like; and a briquetter which compression-molds the pyrolyzed coal thus pyrolyzed, and the like. The coal reforming apparatus has a radical scavenger supplier which supplies drying gas with a radical scavenger so that the low-quality coal can be dried in an atmosphere containing the radical scavenger, the drying gas being supplied from a drying gas supply source and heated by a heater, the radical scavenger being formed of an organic compound having a hydroxyl group.
Claims5
