摘　　要：在1台采用中速磨正压直吹式制粉系统燃烟煤的670t/h直流煤粉锅炉上,对百叶窗浓缩器分离特性进行了单相及气固两相试验,得出了可动叶片倾角、弯管对浓缩器阻力、浓一次风份额、分离效率、浓缩率等参数的影响规律,为燃烟煤锅炉采用水平浓淡燃烧技术实现低NOx燃烧奠定了基础。Air and airparticle experiments about louver enricher characteristics have been done on a 670t/h, cornerfired, pulverizedcoal fired boiler burning the bituminous coal. The boiler has the pressure direct system of pulverized fuel preparation. Influence of regulating blade angle and pipe blending on resistance, ratio of flux of the fuelrich primary air, separation efficiency and concentration ration is gotten. The results found the fundament for low NOx combustion on the bituminous coalfired boiler with Horizontal Bias Combustion technology. Figs 6 and refs 11.
