Integrated coal gasification combined cycle facility

Provided is a composite-type coal gasification power plant facility in which the power generation efficiency can be prevented from being lowered even if a low-grade coal having relatively high moisture content is used. The power plant facility is characterized in that the facility comprises a gasifi...

Beschreibung
Zusammenfassung:	Provided is a composite-type coal gasification power plant facility in which the power generation efficiency can be prevented from being lowered even if a low-grade coal having relatively high moisture content is used. The power plant facility is characterized in that the facility comprises a gasification part (3) for gasifying the supplied coal, a gas power generation part (4) for generating electric power by using the gas supplied from the gasification part (3), a steam power generation part (5) for generating electric power by using the heat of the exhaust gas discharged from the gas power generation part (4), and a coal drying part (15) for drying the coal by using the exhaust heat discharged from the steam power generation part (5) and supplying the dried coal to the gasification part (3).
