蒸汽锅炉事故中,受热面爆管故障所占的比重最大,因爆管泄漏而停炉检修所造成的经济损失难计其数,对人身安全也构成相当大的威胁,尤其值得注意的是,这些爆管故障绝大多数是由于锅炉不完善的设计、制造、安装、使用而造成的。即这种故障原因,多数不是设备使用年久的老化问题,而是设备有先天性缺陷,或是运行操作和检修维护不当,或者是安全和质量管理水平不高,使锅炉受热面不到寿命期限而发生不应有的过热爆管或磨损破裂故障。本文根据笔者对电站蒸汽锅炉的实践体会就受热面各种异常情况的爆管故障作简要分 In the case of steam boiler accident, the proportion of the fault of explosion pipe on the heating surface is the largest, the economic losses caused by the shutdown of pipe explosion caused by the squib leak are difficult to be counted, posing a considerable threat to personal safety. In particular, Most of these squib failures are due to imperfect boiler design, manufacture, installation, use and cause. That is the reason for the failure, the majority of aging equipment is not used for a long time, but the inherent defects of equipment, or operation and maintenance of improper maintenance, or safety and quality management is not high, the boiler heating surface life expectancy Unexpected period of overheating rupture or wear and tear breakdown. This article according to the author of the experience of power plant steam boilers on the heating surface of a variety of unusual circumstances burst tube fault for a brief
