Hydrodynamic Behavior in Palm Shells and Sand Mixtures Fluidization

Utilization of palm shells in gasification technology known as Compartmented Fluidized Bed Gasifier (CFBG) system which uses air as a gasification agent to produce a high heating value of syngas for power generation and chemical processes. Hence it does not only give the potential source of renewable energy but also utilizing the waste in a sustainable way. Fluidization quality is a determining factor in CFBG to guarantee its well-mixed behavior when gasification is concerned. The fluidized behavior of sand / palm shell binary mixtures of different particles sizes and densities is studied in CFBG of 66 cm ID consisting of two compartments combustor and gasifier in a respective ratio of 2:1 fluidized with air. The minimum fluidization velocity (Umf) fluidization quality (Q) incipient bed voidage incipient and expanded bed height are reported in 2 5 10 and 15 weight percentage of palm shells.
