六角切圆燃烧锅炉烟气偏差的冷模试验研究

Research on Cold Test for Gas Temperature Deviation of Boiler with Six Angles Tangential Firing

针对六角切圆燃烧锅炉水平烟道入口烟气温度偏差问题 ,利用模化理论建立试验台 ,进行冷态模化试验。在不同的燃烧器组合工况下 ,对水平烟道入口气流分布进行了研究 ,提出了残余旋转是造成水平烟道内烟气偏差的主要原因 。

Aimed at the deviation of gas temperature in the input of level gas flue of six angles tangential firing boiler,the cold modeling test is put on building the test stand by using the modeling theory.The distribution of air flow in the flue under various running modes of burners is presented.The conclusion is that remains rotation is main factor leading to the deviation of gas temperature.The deviation is enhanced under the burner with less angles running.
