circulating fluidized bed technology

Circulating Fluidized Bed Technology ScienceDirect

The multisolid pneumatic transport bed is a fluidized bed in which a circulating bed of fine particles is superimposed on a slugging or turbulent fluidized bed of dense particles. Pessure fluctuations were measured in the dense particle bed of a 0.102 m I.D. multisolid pneumatic transport bed using two differential pressure transducers.

CIRCULATING FLUIDIZED BED REACTOR Chemical

Jun 09, 2019· 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

Circulating Fluidized Beds: Chemical Engineering

Fixed bed reactors are the technology of choice due to ideal gas flow patterns and straightforward scale‐up. For highly exothermic (or endothermic) catalytic reactions, turbulent and circulating fluidized beds have lower investment and operating costs. Catalyst performance, i.e., activity and selectivity, are the determining economic factors.
