Pressure distribution and particle concentration in bubbling fluidized beds

Paper in proceeding, 1989

The expansion of and particle concentration in large-particle (>0.5 mm) bubbling beds, fluidized at high gas velocities (U-Umf>1 m/s) have been studied in a boiler with 10 m2 hot bed and in a cold two-dimensional bed. The significantly different behaviour of a freely bubbling versus a tube-filled bed at high gas velocity is demonstrated.
