摘要
以YF发电厂330 MW机组为例,分析了锅炉省煤器出口氧量出现偏差的原因。通过一次风热态调平、粉量偏差调整、配风方式调整和磨煤机分离器挡板开度调整,解决了锅炉省煤器出口氧量偏差大的问题,提高了炉膛燃烧的均匀性,锅炉效率提高约0.2百分点。
Taking the 330 MW 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.
