Zusammenfassung:A thermal power plant that uses low-grade coal as fuel and allows for increased thermal efficiency of the entire plant is provided. The thermal power plant includes a drying device (3) that dries the low-grade coal to be supplied to a lignite mill (coal pulverizer) (4), and a drying-gas heater (13) that heats air to be supplied to the drying device (3) so as to be used for drying the low-grade coal. A condenser (12) and the drying-gas heater (13) are connected with each other via a heat exchanger (19), and exhaust heat from the condenser (12) is used as a heat source for heating the air.
