【Abstract】 The core outlet temperature of the high tem pe rature gas-cooled reactor (HTR) can reach 950 ℃, so various power conversion systems could be coupled with an HTR. Indirect steam-gas turbine combined cycle is a potential technical trend. Based on current technical conditions of the HT R and power conversion components, four schemes are suggested and their cycle ef ficiencies are analyzed. At the same time, significant factors which influence c ycle efficiencies are analyzed. The indirect combined cycle, which consists of a steam cycle and a nitrogen gas turbine cycle with a pre-cooler, could be the f irst choice. The cycle efficiency can be over 47 % for the core outlet temperat ure of 950 ℃.更多还原
