Fluidised Bed Combustion

Fluidized Bed Combustion takes place when the forced draught fan supplies air to the Furnace of the Boiler.

Bed material in the form of sand is used to even out heat fluctuations and make the combustion of the fuel more efficient.

The fuel supplied by fuel conveyor is fed to the preheated bubbling sand and gets combusted away. This phenomenon also ensures complete combustion of the Fuel.

The heat released during combustion heats up the surrounding boiler tubes and generates steam. The major advantages of Bubbling Fluidized combustion are the enhanced thermal efficiency and easy ash removal.
