介绍了凝汽器冷却管在蒸汽侧发生腐蚀的工作机理，不但与低压缸的高速排汽流和凝汽器的负荷有关，还与冷却管的材质和某些结构有关，也与附加流动的正确排入有关。防止措施的正确实施可以完全杜绝冷却管在凝汽器蒸汽侧的腐蚀 The working mechanism of condenser cooling tube corrosion on steam side is introduced. It is not only related to the high-speed exhaust flow of low pressure cylinder and the load of condenser, but also to the material of cooling tube and some structures, and also to the additional flow Properly related to the discharge. Correct implementation of preventive measures can completely eliminate the corrosion of the cooling pipe on the steam side of the condenser
