摘要
介绍了凝汽式汽轮机组凝结水过冷度的概念和表示方法;分析了发生凝结水过冷的原因及其对机组运行安全性和经济性的影响;并从凝汽器的设计、检修及运行维护的角度,提出了防止凝结水过冷却的对策。
The concept of undercooling, of condensing steam turbine＇s condensate water, and the way of expressing it is being explained; the cause of its accurrence is analyzed, together with effects on the set＇s operational safety and economy. Countermeasures for preventing undercooling of condensaties are suggested from points of view of condenser design, maintenance and operation.
