凝汽器的腐蚀泄漏严重影响机组的水汽品质，威胁机组的安全经济运行。以某厂铜管腐蚀情况为例，采取加强循环冷却水的硫酸、稳定剂及MBT （2-琉基苯并噻唑，有机铜缓蚀剂）的加药量、定期投胶球运行、管板刷漆保护、FeSO4镀膜、MBT镀膜等防护措施，在凝汽器铜管腐蚀保护方面取得一定的效果。
凝汽器的腐蝕洩漏嚴重影響機組的水汽品質，威脅機組的安全經濟運行。以某廠銅管腐蝕情況為例，採取加彊循環冷卻水的硫痠、穩定劑及MBT （2-琉基苯併噻唑，有機銅緩蝕劑）的加藥量、定期投膠毬運行、管闆刷漆保護、FeSO4鍍膜、MBT鍍膜等防護措施，在凝汽器銅管腐蝕保護方麵取得一定的效果。
응기기적부식설루엄중영향궤조적수기품질，위협궤조적안전경제운행。이모엄동관부식정황위례，채취가강순배냉각수적류산、은정제급MBT （2-류기분병새서，유궤동완식제）적가약량、정기투효구운행、관판쇄칠보호、FeSO4도막、MBT도막등방호조시，재응기기동관부식보호방면취득일정적효과。
The vapour quality is seriously affected by eroded condenser leaking, which threatens the safe and economic operation of the unit. Take a power plant as an example,protective measures were adopted,including increasing the dosage of sulfuric acid,stabilizers and MBT in the circulating cooling water,putting in rubber ball regularly,managing on tube sheet painting,FeSO4 coating, MBT coating and other protective measures. Consequently,the condenser brass corrosion protection achieved certain effects.
