Fluidized bed - Wikiped

2019-6-6 · A fluidised bed is a physical phenomenon occurring when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid. This is usually achieved by the introduction of pressurized fluid through the particulate medium. This results in

Fluidized bed reactors are heterogeneous catalytic reactors in which the mass of catalyst is fluidized. This allows for extensive mixing in all directions. A result of the mixing is excellent temperature stability and increased mass-transfer and reaction rates. Fluidized bed reactors are capable of handling large amounts of feed and catalyst.

Fluidized Beds - an overview | ScienceDirect Topi

Fluidized beds operate by balancing the downward gravity forces of the weight of the particles in the charge with the upward forces created by high gas flow. Fluidization or suspension can be carried out on a large range of material densities and particle sizes. In practice, particle sizes from 0.002 to 10 mm have been successfully treated. However, to ensure that a stable fluid bed is

Fluidized bed combustion - Wikiped

2019-6-14 · Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.

Fluidized bed drying - Glatt Integrated Process Solutio

Fluidized bed drying is the optimal method for controlled, gentle and even drying of wet solids. The intensive heat/mass exchange of the fluidized bed product makes this method particularly effective and time-saving. The technology is also suitable for post-drying of spray granulated or extruded products with very low residual moisture.
