Abstract
An object of the present invention is to provide a pulverized coal drying system for a pulverizer, a pulverized coal drying method therefor, a pulverized coal drying program, a pulverizer, and an integrated gasification combined cycle capable of stably drying a carbonaceous feedstock irrespective of the type of the carbonaceous feedstock to be used. There is provided a controller (50) of a pulverizer (10) that dries a supplied carbonaceous feedstock by using a drying fluid and includes a flow rate controller that controls the flow rate of the drying fluid within upper and lower limits of the flow rate of the drying fluid that are set to dry a plurality of types of the carbonaceous feedstock having different moisture contents in such a way that the temperature of the drying fluid discharged from the pulverizer (10) approaches a target temperature.
