Abstract

The exhaust gas treatment apparatus according to the present invention is provided with: a dust collector provided to a flue; a temperature reduction tower for spraying water into exhaust gas, the temperature reduction tower being provided between the dust collector and a combustion chamber in the flue; a first chemical supply unit for suppling an exhaust gas treatment chemical including a calcium-based chemical to a position between the temperature reduction tower and the combustion chamber in the flue; a second chemical supply unit capable of supplying the exhaust gas treatment chemical including a calcium-based chemical to an auxiliary supply position between the dust collector and the combustion chamber in the flue; an HCl concentration measurement unit for measuring the HCl concentration in the exhaust gas; and a control unit for increasing the amount of the exhaust gas treatment chemical supplied by the first chemical supply unit or the second chemical supply unit to an amount greater than the amount thereof at the time the HCl concentration is less than a predetermined value when the HCl concentration is equal to or greater than the predetermined value. Desalination treatment is thereby performed with good efficiency, and it is possible to appropriately respond in the event of an abnormality in which the HCl concentration is equal to or greater than the predetermined value.
