<p>FLUIDIZED BED SULFUR DIOXIDE REMOVAL System for reducing the emission of sulfur particularly for high sulfur coal combustion in a fluidized bed by injecting limestone into the bed and calcining the limestone in the bed to form lime, reacting a portion of the lime so formed with a portion of the SO2 generated in the bed, removing the material containing excess of the lime so generated from the bed, slaking said excess lime in water, then contacting flue gases leaving the fluid bed and containing SO2 with the lime slurry so formed thereby to remove a further significant portion of the generated SO2 from the flue gas.</p> |
