摘　　要：集中供热建设项目环评中,选择采用低过量空气系数的锅炉本体设备及加强锅炉运行管理方案来控制NOx排放。选用的锅炉过量空气系数低于1.43,同时控制过量空气系数α数值,最终烟气中NOx排放浓度折算为143mg/m3,NOx能达标排放。The boilers with low excess air coefficient were chosen in the environmental impact assessment of a central heating project,meanwhile the scheme of enhancing management of boiler operation was used to control NO_X emission.The low excess air coefficient of the selected boilers was lower than 1.43,by which NO_X emission concentration in fume could be reduced to 143 mg/m3.The index of NO_x can meet the emission standard.

关 键 词：集中供热 环境影响评价 NOx污染控制
