CIRCULATING FLUIDIZED BED REACTOR - Chemical

A circulating fluidized-bed (CFB) reactor is extremely the same as a bubbling fluidized-bed reactor. the main distinction is that the gas rate.If the gas rate of a bubbling fluidized bed will increase, at some Location the force exerted on the particle are enough to move it upwards, carrying it outside of the bed. this case is named elutriation. In a CFB, elutriation carries each sand and char
