  • INTRODUCTION TO FLUIDIZED BEDS

    a shallow fluidized bed of (Hmf/Dt) < 2 with Group B and D particles, Canada et al. (1978) and Dunham et al. (1993) found that Uc increased with static bed height. This could be related to the undeveloped bubble flow in shallow beds before transition to turbulent fluidization can occur (Bi et al. 2000). Particle Size and Density

  • Fluidized Bed Reactor an overview ScienceDirect Topics

    Several variants of fluidized bed reactors with different fluidization regimes (risers, downers, circulating fluidized beds, spouted beds and so on) have evolved over the years [58, 86]. Fluidized reactors offer several advantages, such as rapid mixing of phases (uniformity in product quality), excellent rates of heat and mass transfer and relatively simple operations.
