采用三维相位多普勒颗粒分析仪 (PDPA)对旋流浓淡煤粉燃烧器出口区域冷态两相流动特性进行了实验研究 ,获得了该燃烧器在不同旋流叶片开度、不同煤粉浓缩构件遮盖度、不同旋流二次风和直流二次风配比下的气固两相流场和浓度场的分布规律 ,并进行了讨论分析
A three-dimensional phase-Doppler particle analyzer (PDPA) was used to study the cold-state two-phase flow in the exit region of the swirling briquette pulverized coal burner. The results showed that the opening of the burner at different swirl vanes and different pulverized coal concentration Component coverage, the distribution of the gas-solid two-phase flow field and the concentration field under the different cyclone secondary and direct-flow secondary air ratio, and discussed and analyzed
