Circulating fluidized bed reactor design and operation

The circulating fluidized bed reactor has unique qualities which differentiate it from other gas-solid contactors and make it promising for a wide range of reactions. A 0·15 m × 0·15 m × 7·3 m tall circulating bed reactor with solids returned via anL-val e has been established at the University of British Columbia for combustion of a wide range of solid and heavy liquid fuels. The reactor is heavily instrumented to allow reaction characteristics to be related to reactor hydrodynamics and transfer processes. Novel features are incorporated to permit measurement of solids circulation rates and in the configuration of secondary gas entry ports. Preliminary heat transfer data, temperature profiles and pressure profiles are reported for operation at high temperatures.
