摘要： A thermal power generation system includes a combustor burning oxygen and fuel with supercritical CO2, a turbine driven by the supercritical CO2 and water vapor fed from the combustor, a low-pressure supercritical CO2 storage storing low-pressure supercritical CO2 from the turbine, a compressor compressing the low-pressure supercritical CO2, a high-pressure supercritical CO2 storage storing high-pressure supercritical CO2 from the compressor, and a high-pressure supercritical CO2 feeder supplying between the high-pressure supercritical CO2 storage and the combustor, in which the high-pressure supercritical CO2 feeder supplies the high-pressure supercritical CO2 to the combustor at a constant pressure. Thus, the thermal power generation system can perform adjustment of an electric power supply required to use unstable renewable energy sources such as solar and wind power, can achieve high efficiency power generation with high temperature working fluid, and can reduce emissions of environmental load substances such as NOx and CO2.
