Abstract

In this study, the behavior of gas dispersion in a bubbling fluidized bed was investigated. Carbon dioxide was used as the tracer gas. Most of the gas jets from tuyeres are towards the same direction, parallel with the longitudinal axis. The movement of particles in the lateral direction was enhanced by the momentum of horizontal gas jets within the bed.

The experimental results show that the effect of superficial gas velocity on the gas mixing depends on the distributor type. Comparing with perforated distributor, a better performance of gas mixing was observed while the bed was equipped with horizontal nozzle distributor.

分布器设计对鼓泡流化床内气体分散的影响
本文研究了鼓泡流化床中气体的分散行为。二氧化碳被用作示踪气体。从风口喷出的大部分气体都朝着同一方向,与纵轴平行。床层内水平气流的动量增强了颗粒的横向运动。实验结果表明,表面气速对气体混合的影响与分布器类型有关。与有孔分布器相比,卧式喷嘴分布器的混合效果更好。
