Fluidized Bed Combustion | Types and Advantages of

Fluidization is a method of mixing fuel and air in a specific proportion, for obtaining combustion. A fluidized bed may be defined as the bed of solid particles behaving as a fluid.It operates on the principal that when an evenly distributed air is passed upward through a finely divided bed of solid particles at low velocity, the particles remain undisturbed, but if the velocity of air flow is

A fluidized bed behaves like a liquid, so both the bed level and temperature can be easily controlled. The relatively large mass of moving bed material continually exposes new surfaces of the fuel particles for combustion, sustaining the rapid combustion within the bed. The rapid combustion enables very good load response to be maintained.
