摘要
本文介绍了含湿混合气体在垂直管内对流冷凝换热的特点 ,并对其进行了实验研究 ;通过对实验数据的处理和分析 ,得出实验点与关联式误差在± 2 0 %的范围内 ,气膜热阻是混合气体中水蒸汽凝结的主要热阻 ;
The characteristic of convection-condensing heat transfer of wet flue gas in a vertical tube was introduced and it was studied experimentally. Experimental results showed that the fractional error of experimental data and empirical formula was in ±20%. Gas film is main thermal resistance in the process of vapor condensation. Some factors affecting heat transfer of mixture gas were analyzed finally.
