摘　　要：对进口的Ｅ—２３２型悬臂式两级烟气轮机的二级动叶片断裂进行了分析，其原因是由于材料热处理温度偏高、烟气中催化剂粉尘浓度高、叶片被冲蚀减薄而产生的疲劳断裂。最后提出了防止断裂的对策。The second stage dynamic blade fracture of important E232 cantilevered two stage flue gas expander is analyzed. The fracture cause are the higher heat treatment temperature, high concentration of catalyst powder in flue gas, and the blade thickness decreased by impulsed corrosion,then induced fatigue fracture. And finally,the counter measures to prevent from fracture are given
