空冷机组汽轮机叶片积盐原因分析

摘要

Since the air quality is poor in the northern cities and the cooling spray device is used when the temperature is high,the condenser surface is always exposed to the grey water. Therefore,the condenser fins have heavily scaled,which develops into such a heavy heat insulation layer as to impede the heat exchange performance of the condenser. Taking the 300 MW direct air-cooling unit as an example,using high-pressure water jet to clean the air-cooling condenser can improve the radiator’s cooling performance and greatly increase the economic efficiency of the air-cooling unit.%　　通过对300 MW空冷机组汽轮机叶片积盐情况，以及结垢和积盐特征的分析，探讨了结垢和积盐的形成原因，并提出可通过加强锅炉停用保护、强化机组检修期间的的技术监督、开展热化学试验等措施解决此类问题。
