PROBLEM TO BE SOLVED: To solve a defective point of a conventionally known system and method, regarding a system and a method for controlling some of wet flue gas desulfurization steps.SOLUTION: Oxidation control is carried out by a system which is for controlling oxidation of sulfite ions in a slurry and which has a tank having an inlet for receiving a slurry and an inlet for receiving a gas (the inlet for receiving a gas in the tank is so composed as to diffuse at least a portion of the gas received in the tank through at least a portion of a slurry received in the tank); a sensor so configured as to measure the sulfite ion concentration Sin the slurry received in the tank; a controller; and a software executed in the controller for generating a signal for instructing control of the flow rate of the gas to the tank at least partially based on the sulfite ion concentration S. |
