摘　　要：分析了螺旋肋片管省煤器的防磨机理 ,并采用DSFD法对其结构进行了优化计算 ,可为省煤器的设计和改造提供参考。In this paper, the reasons and laws of ecnomizer abrasion are discussed, and DSFD optimization method is used in construction calculation. The conclusion can be drawn that spiral-finned-tube economizer has great advantages over bare-tube ecnomizer in anti-abrasion and heat transfer. So it can give some constructive advice for economizer designing and calculating.
