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
討論了飛灰磨損性能、管壁受飛灰沖蝕的近似計算、灰粒對順列管和錯列管的磨損計算、煙氣走廊引起對流管束的磨損機理、空氣動力參數對飛灰沖蝕的影響以及受熱面壁溫變化及煙氣成份對飛灰磨損的影響等問題。接著提出了解決的措施：降低平均煙氣流速；降低飛灰濃度；使用鰭片管、螺旋翅片管代替光管；選擇合適的結構及排列方式，減少煙氣中so3的含量；提高受熱面壁溫使之大於煙氣的露點溫度；採用抗腐蝕材料作受熱面等防腐蝕的措施。 -
