The supercritical CO2 power cycles have got lots of attentions for the application to diverse heat sources. The advantages of supercritical CO2 power cycles are higher cycle efficiency and smaller footprint compared to the conventional steam cycles. Thus the supercritical CO2 power cycle could be applied to the retrofit of the conventional coal power plants. In this paper, the results of basic design of a supercritical CO2 power cycle for the coal power plant application would be introduced.
