Summary:The present invention relates to a supercritical CO_2 power generating system for preventing erosion at a low temperature which is able to improve reliability with respect to erosion at a low temperature. The present invention supplies a part of low temperature operating fluid at a rear end of a compressor as an auxiliary recuperator such that the temperature of the operating fluid can be heated up to or greater than a dew point of a waste heat gas for supply. Therefore, an erosion phenomenon occurring in an exterior heat exchanger at a low temperature can be reduced such that the life span of the exterior heat exchanger can be increased. In addition, reliability of the exterior heat exchanger and the supercritical CO_2 power generating system can be improved. 본 발명은 저온 부식에 대한 신뢰도를 향상시킬 수 있는 저온 부식 방지를 위한 초임계 이산화탄소 발전 시스템에 관한 것으로, 본 발명은 압축기 후단의 저온 작동 유체 일부를 보조 리큐퍼레이터로 공급시킴으로써 작동 유체의 온도를 폐열 기체의 이슬점 온도 이상으로 가열해 공급할 수 있다. 따라서 외부 열교환기의 저온 부식 현상을 저감해 외부 열교환기의 수명을 증가시키고, 외부 열교환기 및 초임계 이산화탄소 발전 시스템의 신뢰성을 향상시키는 효과가 있다.
