电站锅炉引风机改造后振动原因分析及处理

Vibration Reason Analysis and Treatment after Boiler Induced Draft Fan Reformation in the Power Plant

概述了清河发电厂６号炉两台引风机进行提高出力的技术改造后，高速运行时存在的振动问题。分别叙述了振动现状测试、气流激振试验及振动变化观察试验情况。分析了振动原因，提出了处理措施，得出了处理效果良好的结论。

Vibration problems existed when operating at a high speed after 2 induced draft fans of № 6 boiler in Qinghe power plant are technically reformed to improve output are described.The vibration status measurement,gas flow activation test and vibration change observational test coditions are separately described.The vibration reasons are analyzed, the treatment measures are provided,and good treatment result conclusions are obtained.
