摘要研究了配煤比例变化对燃煤锅炉尾部受热面飞灰磨损的影响。 - It tell us : the abrasive capability of fly ash ; the similar calculation of ash erosion ; the calculation of ash erosion in the tube in turn and tube out of turn ; the reason of tube abrasion for gas flue ; the influence of air parameter for fly ash erosion ; the influence of changing temperature ; the influence of the flue gas composition , etc . next , it advances the solving measure ; reduce the flue gas velocity ; reduce the concentration of fly ash ; responsible construction : replace smooth tube with spiral tube ; use the new material of abrasion ; fuel desulfurization ; reduce so3 of flue gas ; raise flue gas temperature , making it up the dew point ; use the abrasion - resistance material to resist abrasion
讨论了飞灰磨损性能、管壁受飞灰冲蚀的近似计算、灰粒对顺列管和错列管的磨损计算、烟气走廊引起对流管束的磨损机理、空气动力参数对飞灰冲蚀的影响以及受热面壁温变化及烟气成份对飞灰磨损的影响等问题。接着提出了解决的措施：降低平均烟气流速；降低飞灰浓度；使用鳍片管、螺旋翅片管代替光管；选择合适的结构及排列方式，减少烟气中so3的含量；提高受热面壁温使之大于烟气的露点温度；采用抗腐蚀材料作受热面等防腐蚀的措施。 - This paper also analyzes the ash wear mechanism , and then does the effects of low temperature economizer wear five factors : the first is the smoke corridor caused by wear mechanism , the second is the impact on the wall material , and the third is that of flying ash concentration , the fourth of the excess air ratio , and the fifth is the change in the composition of the gas to wear the impact
分析了飞灰磨损的机理，然后分析了影响低温省煤器磨损的5种因素，一是烟气走廊引起磨损的机理；二是管壁材料的影响；三是飞灰浓度的影响；四是过量空气系数的影响；五是烟气成分的变化对磨损的影响。 - In this paper , analysis and research have been carried out to deal with a lot of problems such as too low temperature for the reheating stream , too high temperature for the flue gas emitting from the furnace and too serious fly ash abrasion for the low temperature reheater of 670t / h coal - fired boiler in power plant
