能源科学技术 浓缩器 Air and airparticle experiments about louver enricher characteristics have been done on a 670t/h, cornerfired, pulverizedcoal fired boiler burning the bituminous coal. The boiler has the pressure direct system of pulverized fuel preparation. 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。
