Flow through Packed Beds and Fluidized Beds

A fluidized bed is a packed bed through which fluid flows at such a high velocity that the bed is loosened and the particle-fluid mixture behaves as though it is a fluid. Thus, when a bed of particles is fluidized, the entire bed can be transported like a fluid, if desired. Both gas and liquid flows can be used to fluidize a bed .

Fluidized Bed Drying of Pharmaceutical Materials: Moisture ...

Apr 02, 2013 · We have varied the initial moisture content inside the pharmaceutical materials from 6% to 20% because in pharmaceutical manufacturing, fluidized bed drying is generally carried out after the wet granulation step and the moisture content in the wet granules is normally in this range. The impacts of air flow and air temperature on the drying process were also investigated.

Technology Overview: Circulating Fluidized-Bed Combustion

Westinghouse has estimated that pressure losses for atmospheric pressure circulating-bed boiler systems would be about 2.7 in. W.C. per foot of bed height and that overall pressure loss including combustor, air preheater, particulate control, convection heat transfer, ducting, etc., would range from 50 to 80 in. W.C.

How Circulating Fluidized Bed Boilers Work?

Fluidized Bed. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.
