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 … 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.

When the bed becomes less uniform and bubbles of air form while the bed becomes more violent with increasing air flow, this is known as a bubbling fluidized bed (BFB) [28]. As the flow of … When the bed becomes less uniform and bubbles of air form while the bed becomes more violent with increasing air flow, this is known as a bubbling fluidized bed (BFB) [28]. As the flow of air increases further, particles blow out of the bed and the container; the velocity then reaches the region that is experienced in circulating fluidized beds (CFBs). [PDF]
