A fluidized bed is a physical phenomenon that occurs when a solid particulate substance usually present in a holding vessel is under the right conditions so that it behaves like a fluid. Heat and mass transfer rates between gas and.

Fluidized Bed Reactor Wikipedia

Gas distributor Inlet to cyclone.

. Fluidized beds typically are more complex to design build and operate than other types of reactors such as packed-bed and stirred-tank reactors. Scaleup of fluidized beds can be difficult 1. Advantages Disadvantages It has the ability to process large volumes of fluid.

Solids losses can result in significant operating costs especially when the solid particles are. The usual way to achieve a fluidize bed is to pump pressurized fluid into the particles. Fluidized beds are prone to erosion and particle attrition caused by the moving particles.

The fluidizing medium is either a gas or a liquid. Fluidized Bed Reactor Components CHEMICAL REACTION ENGINEERING LABORATORY The material fluidized is a solid catalyst. In a BFB gasifier the fluidising gas including gasification agent and producer gas flows through a bed.

In order to achieve uniform distribution of temperature profile and improve the gasification performance fluidised bed gasifiers have been developed for medium- to large-scale plants which are bubbling fluidised bed gasifiers and circulating fluidised bed gasifiers. The resulting medium then has many properties and characteristics of normal fluids such as the ability to free-flow.
