Abstract: A supercritical CO2 power generating system prevents cold-end corrosion capable of improving reliability against cold-end corrosion by including a recirculation pump. Part of the working fluid heated in the low-temperature-side external heat exchanger using the recirculation pump is mixed with the low-temperature working fluid at the rear end of the pump, to heat the working fluid above the temperature of the dewpoint of the waste heat gas. The heated working fluid is then supplied to the external heat exchanger. By reducing the cold-end corrosion phenomenon of the low-temperature-side external heat exchanger, the life of the external heat exchanger can be increased and the reliability of the external heat exchanger and the supercritical CO2 power generating system can be improved.
