Circulating Fluidized-Bed Combustion is the boiler that uses a specific technology called ‘Circulating Fluidized Bed Combustion (CFBC)’. This is one way of burning pulverised coal in electricity generation plant. The coal is burnt in a bed of hot particles maintained in flowing air. At adequately high air speed, the bed acts as a fluid resulting in rapid mixing of the particles. The fluidised action promotes complete coal combustion at relatively low temperatures, and provides a means to transfer combustion heat efficiently from the bed to the steam tubes.
