Figure 1: A typical fluidized bed reactor Other factors that also affect the performance include: Bed temperature, particle size, fluidization velocity, bed height, tube location, heat transfer coefficient and pressure drop. By using a fluid bed dryer, the moisture content of pharmaceutical granules and powder can be decreased in a consistent manner. The design of a fluidized bed thermochemical reactor powered by a 2-kW solar furnace is described; the reactor may provide a means for storing solar energy through application of solar power to such processes as the generation of hydrogen from the thermochemical decomposition of water. The 3D-model of the fluidized bed reactor was first solved for a time dependent laminar flow in absence of any reaction. The simulation was performed to determine characteristics of FBR performance, concentration profile of the contaminants, and various prominent hydrodynamic properties (e.g., Reynolds number, velocity, and pressure) in the reactor. 6 is a schematic view of a plug flow, fluidized bed reactor for use as a catalytic reactor; and. In the fluidized bed the product (solids particle) is held in a vertical “gas flow suspension” and thereby ensures optimal process management. Eng.
