摘要
本文在内径140mm的快速流化床中,考察了内置钝体对床内轴向压力分布和径向颗粒浓度分布的影响。实验结果表明,内置钝体构件对于快速流化床中的压力和浓度的分布影响显著,而且大大增强了气固两相的径向混合。
By using the optical fiber probes and pressure sensors, the axial pressure profiles and radial concentration profiles were investigated in a fast fluidized bed ( 140 mm ID ) with bluff-body. It was found that the concentration and pressure profiles are strongly affected by the bluff-body, and the gas-solid mixing in the bed radial direction is also greatly intensified.
