摘要
介绍1台1 021 t／h锅炉蒸发受热面水冷壁管环向裂纹失效情况，对其出现的原因从材料、水质、燃烧3方面分析认为 因水质问题引起的蒸发受热面结垢与火焰贴壁是产生裂纹的主要原因，根据燃烧理论和热力学原理阐述裂纹形成机理，并提出处理对策。
The paper briefs the circular crack failure on the water wall tubes in evaporative heating surface zone of one 1 021 t／h boiler analyzes the occurring causes in terms of material water quality and combustion holds that the scale on the evaporative heating surface arising from water quality and the flame rubbing against water wall tubes are the main causes for cracks and finally based upon the combustion theory and thermodynamics principles explains the crack－forming mechanism and puts forward the handling countermeasures．
