FLUE GAS DESULFURIZER, AND METHOD FOR FEEDING DESULFURIZATION ABSORBENT LIQUID TO THE DESULFURIZER

摘要

PROBLEM TO BE SOLVED: To provide a flue gas desulfurizer capable of reducing the excess feeding rate of an absorbent while maintaining or improving high desulfurization efficiency, and capable of achieving reduction of desulfurization cost, and to provide a method for feeding the desulfurization absorbent liquid to the desulfurizer.;SOLUTION: A flue gas desulfurizer 10 is provided with an absorption tower 11 having an absorbent liquid-storing part 11a for storing the desulfurization absorbent liquid L, and a spray 11c for spraying the absorbent liquid L into the flue gas GI generated in a boiler 1. Besides, in an absorbent liquid-circulation pipe 14 from the absorbent liquid-storing part 11a to the spray 11c, there is provided an electromagnetic wave generator 20 for generating an electromagnetic wave to bring the action thereof into the absorbent liquid L flowing in the absorbent liquid-circulation pipe 14.;COPYRIGHT: (C)2014,JPO&INPIT
