Phrase ash erosion

• This paper analyzes the impact of the variation of coal proportion on flying - ash erosion in heating surface at the rear of coal - fired boiler
• This paper analyzes the impact of the variation of coal proportion on flying - ash erosion in heating surface at the rear of coal - fired boiler
• 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
