Title:
An exhaust-gas-treatment system and a flue gas treatment method
Document Type and Number:
Japanese Patent JP6254012
Kind Code:
B2
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 SO3 in the flue gas supplies CaCO3 to the flue gas flowing in an upstream of the heat exchanger; an upstream SO3 measurement device measures the SO3 in the flue gas flowing in a stream upper than a position where the limestone supply device supplies the CaCO3; and a control device determines a quantity supplied of the CaCO3 based on a relationship between a quantity of the SO3 measured by the upstream SO3 measurement device and a molar ratio of SO3 to CaCO3 and which supplies the determined quantity supplied of the CaCO3 from the limestone supply device to the flue gas duct.
