ABSTRACT: To reduce the running costs of SCR De NOx, Zhangjiakou Power Plant No. 3 boiler burner for transformation after transformation, the burner will reduce the coal combustion process in the furnace of NOx generation. This article focuses on the boiler burners with low nitrogen transformation programs, combined with the 3rd Zhangjiakou Power Plant boiler burner and effect the transformation of the actual situation, On the mechanism of coal-fired units generate NOx boilers and burners for NOx generated control.
