  • Patent number: 10526925
    Abstract: The present invention relates to a supercritical CO2 power generation system of a series recuperative type. According to an embodiment of the present invention, an inlet temperature of a turbine can be increased to increase a work of the turbine, thereby realizing a cycle design having improved turbine efficiency. Further, the number and diameter of pipes connected to a heat exchanger using an external heat source can be reduced to reduce the plumbing related costs, thereby improving economical efficiency.
