摘要：

A supercritical CO(2) gas turbine cycle can be effectively applied not only for the nuclear reactor but also for the fossil fired power plant. Since an inlet temperature of heat source for this cycle is considerably high and the CO(2) pressure is also very high, these become difficult design problems. An introduction of an economizer for the combustion gas leaving a CO(2) heater and a double expansion turbine cycle are effective to solve these problems. A specific design of 300MWe plant is shown. As a result of system design, the cycle thermal efficiency became 43.4%. For the heat exchangers such as the CO(2) heater, the economizer and the recuperators, PCHE type heat exchanger is effective. The component designs for the CO(2) heater, the economizer, S-CO(2) turbines, compressors and the recuperators are shown.
