折流杆式换热器流致振动分析
|
摘要
针对某电厂折流杆式换热器传热管损伤问题,采用基于数值模拟与标准经验公式结合的新方法进行折流杆换热器流致振动分析和故障预测,并将分析结论与换热管的无损检测统计数据进行比较。结果表明,该分析方法所得出的结论在故障位置、故障形式分析等方面与实际情况一致。
For the damage of rod baffle heat exchanger tube of a power plant in practical operation,a new method based on numerical simulation and standard empirical formula has been applied for the flow-induced vibration analysis and failure prediction of rod baffle heat exchanger,and the analysis conclusions were compared with non-destructive testing statistic data of heat exchanger tube. The results show that the conclusions obtained by this analysis method are well consistent with the actual situation in the aspects of failure location and analysis of failure type,etc.
