摘　　要：在煤粉燃烧一维热态实验炉上进行了不同煤种和不同细度的煤粉分级燃烧实验,通过改变分级风送入的位置、一次风过量空气系数、煤粉细度和富燃区燃烧温度等实验工况,以分析分级燃烧时各种因素对煤燃烧过程中NOx生成量的影响规律。Experimentations of air staging combustion have been carried out to investigate the influence rule of NOx emissions by changing the locations of staging air entered furnace, the air coefficients of primary air, the fineness of pulverized coal and the temperatures of fuel abundant section on a one-dimensional stove burning pulverized coal with different kinds and different fineness coals.
