摘要： An air pollution control apparatus includes at least one denitration catalyst layer for reducing the amounts of nitrogen oxides in flue gas from a boiler and oxidizing mercury with hydrogen chloride sprayed into the flue gas. Spraying pipe headers 51 are disposed in a flue gas duct 19. The spraying pipe headers 51 are inserted into the flue gas duct 19 and arranged in a direction orthogonal to the direction of a gas flow in the flue gas duct 19. At least four spray nozzles 52-1 to 52-4 are disposed on the spraying pipe header 51 to form a vertical vortex flow 53 in the gas flow direction. The diffusion of hydrogen chloride is thereby facilitated in a rapid manner. Therefore, the number of the nozzles can be reduced, and the uniformity of the concentration of hydrogen chloride at the location of the catalyst can be ensured even when the spacing between the nozzles is increased.
