(54) System used in cinerator for reducing NOx


(57) The invention provides a system to be used in a cinerator for reducing nitrogen oxide, including a cylindrical catalyst-reaction tower (1) having both an inlet (1A) through which exhaust gas exhausted out of the cinerator is introduced therein, and an outlet (1B), the catalyst-reaction tower (1) being divided inside thereof into a mixture-dispersion area (1C), and a catalyst layer area (1D), a nozzle unit (2) through which aqueous ammonia is atomized into the catalyst-reaction tower (1), first and second area-contractors (21, 22) arranged in the mixture-dispersion area (1C), each of the area-contractors (21, 22) having at least one opening (21a, 22a), the opeing (21a) of the first area-contractor (21) being located in no coincidence with the opening (22a) of the second area-contractor (22), and a catalyst (23) included in the catalyst layer area (1D).
