<p><P>PROBLEM TO BE SOLVED: To provide an apparatus and a method for preventing scale generation in a wet system for flue gas desulfurization. <P>SOLUTION: The wet system for flue gas desulfurization involves spraying an alkaline slurry in an upper zone 52 of an absorption tower 50 so as to cause the slurry to come into contact with a flue gas flow and to cause SO2 contained in the flue gas to be absorbed by the alkaline slurry, whereby air is sprayed upward from a plurality of holes of an injector 225 provided on the bottom of an alkaline slurry tank zone 55 placed lower in the absorption tower to the inner wall of the tank zone, so that the alkaline slurry containing SO2 rich after contact with the flue gas is maintained away from the inner wall of the tank zone and scale generation and deposition on the inner wall are prevented. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
