<p>PROBLEM TO BE SOLVED: To provide a method for removing sulfuric acid anhydride in a flue gas capable of reducing a load on an electrostatic precipitator and still removing sulfuric acid anhydride in an exhaust gas, and an apparatus using the same. SOLUTION: The method comprises the steps of forming a moving bed 18 wherein an alkaline mass 24 is used as an adsorbent in the flue from a boiler 10 to a desulfurization equipment 14, adsorbing and removing the sulfuric acid anhydride in the exhaust gas with the alkaline mass 24 in the moving bed 18, classifying the exhausted alkaline mass 24 from the moving bed 18 with a screen 27, recycling the alkaline mass on the screen to the moving bed 18 and slurring the alkaline mass while grinding the powdered alkaline mass under the screen, thereby providing an adsorbent of the desulfurization equipment 14.</p> |
