Abstract
An air pollution control system includes: a desulfurization device which removes sulfur oxides in a flue gas generated from a boiler; a cooler which is provided at the downstream side of the desulfurization device, decreases a flue gas temperature and enlarges a particle diameter of SO3 mist contained in the flue gas through cooling or heating the flue gas by a temperature adjustment means for adjusting a gas dew point temperature of the flue gas; and a CO2 recovery device which includes a CO2 absorber bringing CO2 in the flue gas into contact with the CO2 absorbent so as to remove CO2 therefrom and a regenerator recovering CO2 by dissociating CO2 from the CO2 absorbent and regenerating the CO2 absorbent, wherein the flue gas is cooled by a cooling unit so as to enlarge the SO3 mist in the flue gas.
