管式空气预热器的防振设计示例与分析

Analysis and Example of Antivibration Design of Tubular Air Preheater

给出了判断管式空气预热器是否振动的计算方法 ,并根据卡门涡流频率fk 与气室声学驻波频率fC 的值大小相对比 ,找出合理的解决方案 ,达到消除振动的目的。在实际工程中取得了良好的效果 。

Providing the method of judging whether Tubular air preheater vibrates,and acquainting the practicable method to eliminate the vibration by comparing the value of karman vortex frequency(Fk)with the value of air-chamber acoustic waves frequency(Fc).Now,We receive the good effect in the practicable project.
