Circulating Fluidised Bed Combustion (CFBC) Boilers .

Unlike the Bubbling AFBC boilers the erosion prone submerged heating surfaces are dispensed with. The recirculated cold fly ash takes over the cooling of the fluidised bed. It is in the convection pass that the heat taken is transferred to the convectional heating surfaces. The boiler has a tower-type arrangement. The first boiler pass is formed
