摘　　要：从一起因循环水泄漏造成锅炉水冷壁泄漏的事故,分析了引发水冷壁结垢的多方面原因,采取锅炉酸洗及汽包恢复加药管等相关措施后,及时解决了问题。根据此次事故处理经验分析,当水汽质量劣化时,综合分析系统中水、汽质量的变化,及时按照三级处理原则执行相关措施,可以有效防止热力设备发生腐蚀、结垢、积盐等故障。The causes of water-cooled wall fouling from an accident caused by circulating wa⁃ter leakage was analyzed,and the problem was solved in time by taking relevant measures such as acid cleaning of boilers and recovery of chemical-feed line of steam drum.According to the analysis of this accident treatment experience,when the quality of water and steam deteriorates,comprehen⁃sive analysis of the changes in the quality of water and steam in the system,and timely implementa⁃tion of relevant measures in accordance with the principle of three-stage treatment can effectively prevent the thermal equipment from corrosion,scaling,salt buildup and other failures.
