中国实验快堆(CEFR)采用2台卧式双流程凝汽器,循环水系统及真空系统均采用定速泵,因此机组热效率的高低在很大程度上取决于凝汽器的背压。CEFR是实验堆,汽轮机组在25%热效率验收工况至阀门全开工况均可运行,凝汽器背压范围可达2～30kPa。依据汽轮机组厂家提供的资料以及CEFR实际情况,选取5个典型工况,分析凝
China Experimental Fast Reactor (CEFR) adopts 2 horizontal two-pass condensers, and fixed-speed pumps are used in the circulating water system and the vacuum system. Therefore, the thermal efficiency of the unit largely depends on the back pressure of the condenser. CEFR is the experimental reactor, steam turbine in 25% of the thermal efficiency of the acceptance conditions to full operation of the valve can be operated, the condenser back pressure range up to 2 ~ 30kPa. According to the information provided by steam turbine manufacturers and the actual situation of CEFR, select five typical conditions, analysis of condensate
