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.

Fluidized bed combustion modeling and mixing

The focus of this thesis is on Circulating Fluidized Bed Combustion. The principle of a fluidized bed is that a bed of solid particles adopts a fluid-like behavior when a gas injected from below flows through it. A fluidized bed is known to provide a good gas-solids contact together with relatively high rates of solids and gas mixing. These
