<p>A method, wherein spent residue from a fluidized combustion bed of the type in which lime or limestone particles are suspended in a fluidized medium and a carbonaceous fuel is ignited proximate said fluidized medium to capture therein substantial amounts of SOx which is generated upon ignition of said carbonaceous fuel, the lime component of which has been substantially hydrated by mixing with water, and pozzolanic material, such as pulverized coal combustion system fly ash, are incorporated in a cementitious mix. The mix is cast into desired shape and cured. If desired, the shape may then be crushed so as to result in a fluidized bed combustion residue-fly ash aggregate material or the shape may be used by itself. The method enables a commercially acceptable way of disposing of the spent bed residue by incorporation thereof in a high-strength concrete-like material.</p> |
