Abstract
The air pollution control system including: a flue gas duct through which flue gas flows; a heat exchanger provided to the flue gas duct; a limestone supply device for reducing SOin the flue gas supplies CaCOto the flue gas flowing in an upstream of the heat exchanger; an upstream SOmeasurement device measures the SOin the flue gas flowing in a stream upper than a position where the limestone supply device supplies the CaCO; and a control device determines a quantity supplied of the CaCObased on a relationship between a quantity of the SOmeasured by the upstream SOmeasurement device and a molar ratio of SOto CaCOand which supplies the determined quantity supplied of the CaCOfrom the limestone supply device to the flue gas duct.
