【Abstract】 Using the practical engineering example of the rotary air preheater retrofit adopting’double sealing technique’in a power plant, the conditions of the air preheater before and after the retrofit were introduced. The effect of airleakage rate and tail flue gas temperature on boiler efficiency was emphatically analyzed. The evaluation method forair preheater performance was given also.更多还原
