The present invention relates to an exhaust gas treating apparatus, which comprises an SO_3 remover configured to remove SO_3 from exhaust gas which is generated when fuel including sulfur is burnt. According to the present invention, provided is an exhaust gas treating apparatus comprising an SO_3 remover, the exhaust gas treating apparatus comprising: a primary heat exchanger which is coupled to an incinerator configured to burn fuel including sulfur, and adjusts a temperature of exhaust gas, discharged from the incinerator, to a preset temperature; a selective catalytic reductor which is coupled to the primary heat exchanger, and reduces nitrogen oxide of exhaust gas having passed through the primary heat exchanger; a secondary heat exchanger which is coupled to the selective catalytic reductor, and adjust a temperature of exhaust gas, having passed through the selective catalytic reductor, to a preset temperature; a flue gas desulfurlizer (FGD) which is coupled to the secondary heat exchanger, and removes sulfur oxide of exhaust gas having passed through the secondary heat exchanger; and an SO_3 remover which is coupled to the FGD, and removes SO_3 of exhaust gas having passed through the FGD. |
