| Abstract: | The wear mechanisms of economizer are analyzed in theory,the wear characteristics of economizer tube and its main influence factors are explained as well. Smoke velocity is deemed to take the dominant role in erosion of heated surface after the analysis of the main influence factors. Three causes resulting in higher smoke velocity than the design value are summarized. And eventually,six measures and suggestions to alleviate and prevent economizer wear are presented. |
