摘要
陕西某化工集团热电分公司480t/h锅炉在首次停炉内部检验过程中发现水冷壁严重变形。通过查阅锅炉原始资料和运行检修记录、宏观检验、测厚检验、水冷壁割管和水冷壁下集箱内窥检验,并从水位监测、运行、管理等方面进行分析,得到水冷壁变形的主要原因是锅炉水位监测系统异常和锅炉运行管理方面存在问题导致的高温过热。
Serious deformation of water cooling wall was found in a 480t/h boiler in a thermal power branch company of one chemical industry group in Shaanxi in the first internal inspection. By looking up the boiler operation maintenance records, macro inspection, thickness test, cutting pipe and endoscopic examination, and analysis water level monitoring, operation and management, this paper found that the main reason of water wall deformation was high temperature overheating caused by abnormal boiler water level monitoring system and boiler operation management problems.
