ABSTRACT:
A gasification-type combined electric power generating plant comprises a gasifying furnace, a heat exchanger, a gas purifying device, a gas turbine, and a gas turbine compressor, an exhaust heat recovering boiler, and a steam turbine. To decrease boosting power, increase the energy of recovered heat, and improve the overall efficiency of the plant, the plant further includes a regenerative heat exchanger for cooling an air-like gas bled from the gas turbine compressor, a cooler for cooling the air-like gas passed through the regenerative heat exchanger, a primary air booster for boosting a part of the air-like gas passed through the cooler to deliver a primary air, a secondary air booster for boosting the remainder of the air-like gas passed through the cooler to deliver a secondary air, and a passage through which the secondary air passed through the secondary air booster is supplied to the regenerative heat exchanger where the secondary air is heated and then to the gasifying furnace.
