Abstract
A wet flue gas desulfurization system for removing sulfur dioxide present in flue gas by absorption into an absorbent slurry includes an absorption tower having at a bottom thereof a tank for holding an absorbent slurry; a circulating pump for feeding the absorbent slurry within the tank to a flue gas inlet section in an upper part of the absorption tower and bringing the absorbent slurry into contact with flue gas; and a slurry preparation compartment provided on one side of the tank of the absorption tower and separated from a flue gas passage section by a partition wall having its lower end submerged below a surface of the absorbent slurry, whereby an absorbent and water constituting the absorbent slurry are directly introduced into the slurry preparation compartment.
