摘要：

为解决凝汽器铜管腐蚀结垢问题，进行了蚀坑和沉积物元素分析以及药剂检测，腐蚀挂片、泥沙磨蚀、阻垢等试验，从而得出结论：泥沙磨蚀、垢下腐蚀和运行工况欠佳等原因的综合作用导致了铜管腐蚀与结垢。根据诊断建议，从管板涂膜、水质控制和调整加药工艺等方面采取了缓腐防垢措施，故障消除。

Abstract: In order to solve the corrosion and scaling problems of condenser′s copper tubes, aiming at the corrosion pits and sediment, the element analysis was done; several experiments, such as the reagent detection, the corrosion coupon, the silt abrasion and antiscaling, were carried out. A conclusion was obtained that the comprehensive affect of silt abrasion, the corrosion behind scaling, the bed operation condition and others led the corrosion and scaling of the copper tubes. According to the diagnosis suggestion, some corrosion slowing and antiscaling measures, such as coating film on tubes plate, water quality control and improvement of reagent adding process, were adopted; and the faults were eliminated.
