摘要: This paper illustrates the interrelation between bubbles, solids movement, and gas backmixing in large fluidized beds by presenting experimental data obtained with a 1.22 m square bed. The results demonstrate close relationship backmixing, bubble coalesence, behavior altering markedly as coalescence patterns change.
