A thermal power generation system uses supercritical carbon dioxide 5 as a working fluid, the thermal power generation system. The thermal power generation system includes a combustor 101 burning oxygen 3 and fuel 4 with the supercritical carbon dioxide 5, a turbine 102 driven by the supercritical CO 2 5 and water vapor fed from the combustor 101, a low pressure supercritical CO 2 storage 106 storing low pressure supercritical CO 2 from the turbine 102, a compressor 104 which compresses the low pressure supercritical CO 2 5, a high pressure supercritical CO 2 storage 107 storing high pressure supercritical CO 2 obtained through compression by the compressor 104, and a high pressure supercritical CO 2 feeder supplying the high pressure supercritical CO 2 5 from the high pressure supercritical CO 2 storage 107 to the combustor 101 , in which the high pressure supercritical CO 2 feeder supplies the high pressure supercritical carbon dioxide 5 to the combustor 101 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 NO x and CO 2 . |
