燃煤锅炉省煤器的磨损问题是一个非常复杂的物理及化学过程,影响磨损的因素很多,国外在这方面作了很多试验研究工作,并认为磨损主要与烟气流速(灰粒的速度)、飞灰浓度、灰粒磨损特性、管材的耐磨特性有关。另外,对于省煤器管组的结构尺寸及管径大小与磨损的关系,也不断被人们所重视,近年来国外虽进行了一些试验研究工作,但至今还有不同的认识。本试验的目的就是为了能进一步了解省煤器管组的结构尺寸及管径大小与磨损的规律, Coal-fired boiler Economizer wear problem is a very complex physical and chemical processes, many factors affect the wear, a lot of experimental research done in this regard abroad, and that the wear and tear mainly with the flue gas velocity (soot speed) , Fly ash concentration, ash particle wear characteristics, pipe wear characteristics. In addition, the structure of the economizer tube size and the relationship between the size and diameter of the wear, but also continue to be valued, in recent years, although some foreign experimental research work, but so far there is a different understanding. The purpose of this test is to further understand the structure of the economizer tube size and size and wear and tear of the law,
