<p>PURPOSE:To outstandingly decrease powdering of carbon base adsorbents by causing, in advance, NH3 to be adsorbed to carbon base adsorbents before the adsorbents are brought into contact with combustion gases and passing the combustion gases through a moving bed of the adsorbents in a direction at right angles to the moving bed. CONSTITUTION:Combustion gases containing NoX and SOX are fed to a desulfurization-denitrification tower 1 to be brought into contact with carbon base adsorbents to which NH3 has been adsorbed by means of a NH3 adsorption device 4, wherein SOX is adsorbed in the form of sulfuric acid, ammonium sultate, and acid ammonium sulfate, while NOX is reduced to N2 by the action of NH3. On the other hand, the carbon base adsorbents move through the tower 1 and sent to a desorption tower 2, where sulfur compounds are desorbed from the adsorbents, thereby the adsorbents are regenerated.</p> |
