摘　　要：膜式省煤器在电厂锅炉得到了普遍应用,文章根据其在220 t/h锅炉上的实际应用情况,对膜式省煤器和光管式省煤器的优劣进行比较,并得出具有实际意义的结论,为今后的锅炉对流受热面的改造提供指导。Compared the membrane economizer with properties of bare tube economizer, the former has more advantages.For 220t/h boiler tube economizer＇s severe wear and frequent tube explosion, the No. 1 and No. 2 boiler of low temperature economizer were trans-formed. In fact, it not only improves the boiler efficiency but also ensures no tube explosion.
