Abstract
The causes and affecting factors of air-leakage in the rotary air preheater of boiler no.3 in one power plant have been analysed. Combining with the practical operating condition of boiler no.3 and the structural design of its air preheater
a retrofit scheme of double sealing has been worked out. After implementation
the air-leakage rate of the rotary air preheater has been decreased by a big margin
improving the performance of heat transfer and flow resistance for the said air preheater
enhancing the economic efficiency in operation of the boiler and unit.
