摘要
凝汽器作为核电厂重要的冷源设备,其性能的优劣直接影响着整个机组的热效率。而凝汽器清洁系数和凝汽器修正压力是评价和监测凝汽器性能的两个最重要的指标,但是其定义和计算方法存在异义。文中对其定义和计算方法进行重新推导,指出各种定义的差异和相同之处。在此基础上,对凝汽器性能进行了变工况计算,分析了海水温度、堵管率和海水流量对机组性能的影响。该计算方法简单明了,对同类型电站的凝汽器性能评价有指导作用。
Condenser is one of the important auxiliary equipment in nuclear power plants.The thermal efficiency of the entire unit was depended on the condenser performance.Cleanliness factor and condenser corrected pressure are the two most important evaluation indexes.The definition and derivation of these two evaluation indexes were elaborated and clarified in this paper.And the condenser performance at variable conditions was analyzed.The seawater temperature,pipe plugging rate and seawater volume rate effect on unit output was calculated.The calculation method was simple,which can provide reference guidance for similar power plant.
