摘要
本文通过对燃烧天然气的冷凝式锅炉热效率的分析和计算,得出冷凝式锅炉因为降低了排烟温度,可以充分回收了烟气中的显热和水蒸汽的凝结潜热,所以锅炉热效率高,值得推广使用。
In the paper, author obtained a result that condensing boiler can retrieve both the sensible and the latent heat in flue gas because it is lower the exit flue gas temperature by analysis and calculation the thermal efficiency of natural gas-fired condensing boiler so the thermal efficiency of condensing boiler is very high and it is worth using widely.
