Before entering the existing stack the fluegas has to be reheated to protect the stack against condensates. For reheating the gas gas Heater (GGH) is used.
因此在进入烟囱之前，必须被再度加热而使烟囱不结露，因此烟气换热器就被运用了。

Experimental analysis and study of the fluegas condensation unit is set or not on the catalytic combustion heater thermal efficiency.
通过实验分析和研究了烟气冷凝装置设置与否对催化燃烧热水炉热效率的影响。

The results show that the boiler efficiency increased 1.24% and the fluegas loss reduced 1.41% after installed the heat pipe air heater.
