| description | An air pollution control device according to the first embodiment of the present invention is an air pollution control device for reducing the amounts of NOx and Hg contained in flue gas 12 from a boiler 11. The air pollution control device includes: NH 4 Cl solution supply means 16 for spraying an NH 4 Cl solution 14 by a spray nozzle 15 into a flue gas duct 13 at the downstream of the boiler 11; a mixer 17 provided on the downstream side of a region where NH 4 Cl is gasified, for promoting mixing, with the flue gas 12, HCl and NH 3 which are generated when NH 4 Cl is gasified; a reduction-denitration device 18 including a denitration catalyst for reducing NOx in the flue gas 12 with NH 3 and for oxidizing Hg under the coexistence with HCl; and a wet desulfurization device 22 for reducing the amount of Hg oxidized in the reduction-denitration device 18 using a limestone-gypsum slurry 21. |
