摘　　要：介绍通过实炉实验研究获得了碳钢—铝翅片管束有水蒸汽冷凝换热时的复合放热特性及接触热阻的情况,实验获得的关联式对燃气锅炉冷凝式换热器的设计及运行有参考指导作用。The characteristic of compound convection and con tact heat resistance of saving energy of a boiler with rated output-4 ton steam per hour refitted by adding a condensing device were introduced. In addition, the testing correlation of the compound convection including condensation over elytriform tube banks scoured by low speed smoke were acquired, which had the referential value to design and operation.
