GASIFICATION IN FLUIDIZED BEDS-PRESENT STATUS & DESIGN
Biomass has made great in-roads in its use in energy and chemical industries. Gasification is one of the major means for its conversion. For thermo-chemical conversion of biomass three major gas-solid contacting processes, fixed bed, entrained bed and fluidized bed are used. Various versions of fixed bed gasifier (up-draft, down-draft, and side-draft) proved successful but primarily in small capacity units while entrained bed reactors found favour in very large capacity units. Fluidized bed gasifier fills the important intermediate size range. A review of the current commercial use of fluidized bed gasifier shows that it is yet to take the centre stage in the gasification market. This paper examines the issues preventing wider scale use of fluidized bed gasifier and what is the current state of research in those issues.
