FIELD: power engineering.
SUBSTANCE: combined cycle station with in-cycle coal gasification comprises a gasification section designed for gasification of supplied coal, a gas section of power generation, which generates power through usage of gas arriving from the gasification section, a steam-power section for generation of power, which generates power through usage of heat from spent gas released from the gas section of power generation, and a coal-drying unit, which dries coal through usage of heat of spent gas released from the steam-power section of power generation. The dried coal is supplied into the gasification section.
EFFECT: invention makes it possible to increase station efficiency even when low-grade coal is used with high moisture content.
