A Fluidized Bed Boiler popularly known as FBC Boilers are designed so as fuel particles are suspended in a hot, bubbling fluidity bed of Refractory Bed materials , through which jets of air are blown to provide the oxygen required for combustion . The resultant fast and intimate mixing of gas and solids promotes rapid heat transfer and chemical reactions within the bed. FBC Boilers plants are capable of burning a variety of low-grade solid fuels, including most types of coal and woody biomass, at high efficiency . In addition, for any given thermal duty, FBCs are smaller than the equivalent conventional furnace Boilers , so may offer significant advantages over the latter in terms of cost and flexibility.
Construction FBC Boilers has a water-wall type construction has a steam-water natural circulation system for heat exchange. Vertical in-bed heat exchange tubes are provided and the steam drum of the boiler extends across the full length of the boiler combustion chamber and the convection heat exchange chamber. An air distributor grate is provided for introduction of fluidizing air into the combustion chamber and the air flow therefrom can be controlled to afford a flexible turn-down capability.
