Abstract:
The purpose of the present invention is to provide a pulverized coal drying system for a coal pulverizer and a pulverized coal drying method therefor, and a pulverized coal drying program, the coal pulverizer, and a gasification combined cycle facility, whereby it is possible to stably dry a carbon-containing solid fuel regardless of the carbon kind of carbon-containing solid fuel used. A control unit (50) for a mill (10) which dries the supplied carbon-containing solid fuel using a drying fluid comprises a flow rate control unit that controls the flow rate of the drying fluid to within the upper and lower limits of the flow rate of drying fluid set for drying a plurality of kinds of carbon-containing solid fuel having different moisture contents so that the temperature of the drying fluid discharged from the mill (10) approaches a target temperature.
