三次风下移减小大容量煤粉锅炉烟温偏差的研究探讨

Decrease Flue Gas Temperature Disparity by Changing Postion of Tertiary Air Downward

基于四角切向燃烧锅炉烟温偏差产生的原因和锅炉实际运行参数，提出了将三次风下移来降低大型锅炉燃烧过程中烟温偏差的方法。

Based on reason of flue gas temperature disparity in tangential firing boiler and actual boiler operation parameters, a new way that decreases flue gas temperature disparity by changing position of tertiary air downward is introduced in this paper.
