汽轮机凝汽器真空的影响因素分析及处理

摘要

Heat-transfer process of condenser in operating turbine are introduced in this paper, vacuum reduction reason of given 2× 300 MW NO�1 unit is analyzed and main measure are proposed, which can improve operation efficiency, economy and safety. This paper provides useful references for similar problems of turbine.%介绍了汽轮机运行时凝汽器的传热过程，分析了某厂2×300 MW 1号机组真空降低原因，提出了改善机组真空的主要措施，提高了真空系统正常运行效率，并改善汽轮机经济性和安全性，为存在类似问题的其它型号汽轮机提供借鉴。
