摘　　要：进行了螺旋肋片管束的工业性试验研究,得出了不同横、纵向相对节距的螺旋肋片管束的沾污系数与烟速的拟合关联式,可应用于锅炉的受热面设计及运行分析。The experimental investigation for contamination factor of spiral - finned tube bank is can-led out. Based on the analysis of the conclusion, the incidence formulas and curves for calculating contamination factor of two types of the studied spiral - finned tube banks are obtained. The formulas and curves can be applied widely to the design of boiler heating surface and the operation analysis.
