Abstract:

Abstract:Taking the 330MW unit of YF Power Plant as an example, this paper analyzed the reasons of oxygen content deviation at boiler economizer outlet. And through some measures, such as primary air hot leveling, powder deviation adjustment, air distribution mode adjustment and separator baffle opening adjustment of coal mill, etc., this paper solved the problem of large oxygen content deviation at boiler economizer outlet, which improved the combustion uniformity of furnace and the boiler efficiency is increased about 0.2 percentage point.
