Zusammenfassung:Provided is an absorber 11 that removes sulfur oxide in a flue gas with an absorbent 14, an absorbent storing unit 11b that stores the absorbent that has absorbed the sulfur oxide, an oxidation-reduction potential meter 18 that measures an oxidation-reduction potential of the absorbent 14, a reducing additive supplying unit 20 that supplies a sulfur oxoacid reducing additive 19 into the absorbent 14 or the absorbent storing unit 11b, and a control device 50 that controls the reducing additive supplying unit 20 based on a measured value of the oxidation-reduction potential of the absorbent 14 measured with the oxidation-reduction potential meter 18, wherein the control device 50 controls the reducing additive supplying unit 20 to supply the sulfur oxoacid reducing additive 19 when the measured value of the oxidation-reduction potential has exceeded an upper limit of an appropriate range of the oxidation-reduction potential.
