摘要
针对某600MW超临界火电机组锅炉15CrMoG水冷壁管失效的问题,分析其原因是在制造过程中管壁生成的氧化皮以及在锅炉运行中生成的腐蚀产物大量剥落,导致炉管堵塞和过热爆管。提出采用化学清洗方案后取得了良好效果。
By analyzing the reasons leading to the 15CrMoG tube blockage and overheat burst existing in the water wall of a 600 MW supercritical thermal power unit,the problem was found to be caused by peeling of oxide scales formed during tube manufacture and boiler operation,which was finally solved by taking the way of chemical cleaning.
