| Abstract: | Aiming at the situation of high air leakage of air preheater,the principle of work,the reasons of air leakage of air preheater and transformation ways were compared and analyzed combined with sealing renovation of air preheater in a 300 MW unit. The results showed air leakage of the air preheater with contact flexible seal had been significantly improved,and environmental protection and energy saving effect had been obtained. |
