COMBINED CYCLE POWER GENERATION PLANT UTILZING SOLAR HEAT

摘要

A combined cycle power generation plant that uses solar heat and is equipped with: a compressor (1) that pressurizes air for combustion; a combustion chamber (2) that mixes/burns the aforementioned combustion air (60) and a gas turbine fuel (61) to generate high-temperature combustion gas; a gas turbine (3) that drives the compressor (1) using the aforementioned combustion gas; an exhaust heat recovery boiler (4) that obtains steam from the heat energy of the exhaust gas from the gas turbine (3); and a steam turbine (5) that is driven using steam obtained with the exhaust heat recovery boiler (4). The power generation plant is further equipped with: a heat collector (10) that converts feed water to high-temperature water by means of the heat energy of sunlight; a heat accumulator (9) that stores high-pressure, high-temperature water obtained from the heat collector (10) and the exhaust heat recovery boiler (4); and a spraying device (4) that sprays the high-pressure, high-temperature water stored in the heat accumulator (9) into the intake air of the compressor (1) as a water spray.
