Potential Uses of Fluidised Bed Boiler Ash -

The resulting ash from the boiler bed and trapped fly ash, known as fluidized bed boiler ash (FBA), contains CaSO 4 and unreacted CaO. Mixing this ash with water, to overcome dust problems, subsequently converts CaO to Ca(OH) 2. The chemical composition of FBA is highly dependent on the efficiency of the boilers and the nature of the fuel and
