Exhaust gas treatment system and exhaust gas treatment method

摘要

An exhaust gas treatment system is provided that can sufficiently remove pollutants such as SO 3 contained in combustion exhaust gas at low cost. In the exhaust gas treatment system for removing pollutants such as SO 3 contained in combustion exhaust gas, there is provided dissolved salt aqueous solution sprays 35A, 35B, and 35C, that spray an Na 2 SO 4 aqueous solution obtained from desulfurization effluent of a wet desulfurization system, into a flue though which the combustion exhaust gas flows.
