摘要
锅炉右下集箱产生了很多环状裂纹和三个渗水点，同时顶棚水冷壁管塌陷。通过对左右下集箱、顶棚水冷壁材质的金相组织分析，对锅炉结构及水循环的分析，得出此锅炉下集箱失效的原因。
A multitude of ring-shaped cracks and three water leakage points were discovered in the right side lower header of a boiler together with a cave-in of the boiler roof water-cooled wall.Through the metallographic analysis of the materials used for the left and right side lower header and the said water-cooled wall as well as an analysis of the boiler construction and water circulation circuits the cause of the boiler lower header failure was finally identified.
