空气预热器受热面的磨损

Erosion of Air Preheater Heating Surface

防止或减轻空气预热器受热面的磨损一直是空气预热器选型和设计首要考虑的一个重要问题。介绍了在选型和设计空气预热器时为防止或减轻磨损所采取的方法和措施,并提出了控制最大平均烟速的经验公式供从事空气预热器的设计人员参考。

It is important factor all the while that prevent and lighten potential erosion when selecting air preheater. the means of preventing and lightening erosion while selecting air preheater was introduced. the experience equation of restricting the maximum allowable average flue gas velocity are presented, It may be a reference for the relative persons while doing air preheater design work.
