电站锅炉受热面管内外广泛接触烟、火、灰、水、汽、垢等介质，其工作环境恶劣且复杂，经常会因为各种原因而导致爆管泄漏失效的发生，给企业带来巨大的经济损失。详细介绍了磨损、长期过热、短期过热、氢损伤、腐蚀疲劳、氧腐蚀、应力腐蚀、碱性腐蚀以及酸腐蚀9种常见的电站锅炉受热面管的泄漏失效原因及其主要特征,对迅速确定锅炉爆管原因以及提出解决措施，规范锅炉系统的操作等具有重要指导意义。

Heating surface tubes of utility boiler widely contact the media of smoke, fire, ash, water, steam, scale and etc. The tubes, which have wicked and complex working conditions, often blast and result in leakage failure because of many reasons. These bring huge economic losses to the enterprises. Nine kinds of tube blasting reasons and their main representation characters were detailedly introduced. These tube blasting reasons include abrasive erosion, long-term overheating, short-term overheating, hydrogen damage, corrosion fatigue, oxygen corrosion, stress corrosion, caustic corrosion and acid corrosion. It has important guiding significance to rapidly ascertain the causes and ultimately resolve the tube blasting problems of the utility boiler and to normalize boiler system operation.
