    Flue gas containing sulfur oxides is cooled to a saturation temperature of water or higher and 80 DEG C or lower in a gas cooling apparatus (3), and then introduced into a process vessel (4). Aqueous ammonia is sprayed and injected into the flue gas from a two-fluid nozzle (12) in the process vessel (4), and sulfur oxides in the flue gas is converted into powdery ammonium compound, and then the powdery ammonium compound is collected by a collecting apparatus (6). When aqueous ammonia is sprayed and injected into the flue gas, the aqueous ammonia is pulverized into droplets having a Sauter mean diameter of 0.5 mu m or larger and 30 mu m or smaller.
