摘　　要：东南大学建造了1座IGCC余热锅炉鳍片管受热面流动和传热热态试验装置,并先后在其上进行了2个不同螺旋鳍片管组的传热特性研究,通过分析比较实测的烟气侧对流放热系数与无量纲准则式计算的结果,得出了完全热模拟公式更为准确的结论。An experimental facility was set up to investigate the gas-side heat transfer characteristics of helically finned tube bundles in the IGCC heat recovery boiler. Two different groups of heat transfer surface are evaluated respectively. The gas-side convective heat transfer coefficient was studied. The complete heat simulating formula which is more accuratly are obtained.
