PURPOSE: Provided is an agitator blade for flue gas desulfurization facilities in power plant, which is aimed at preventing solid slurry from being settled in agitation tank by suspending or re-suspending the solid slurry. CONSTITUTION: In four agitator blades(2) radially adhered to agitator shaft(1), the agitator blades are characterized in that hub or impeller blades are adhered to impeller shaft in an angle of 45 degrees, and the agitator blades(2) are formed in such a manner that pitch is geometrically twisted as it goes from root part(24) to end part(23) by bending the agitator blades(2) as much as a certain angle per each time in a diagonal direction along outer sides(22,23) of trailing edge(22) from inner sides(21,24) of leading edge(21), wherein a certain sized plate (vertical stabilizer) is welded to or bolted to a position that is approximately 2/3 to 3/4 distanced to the end part(23) from the root part(24) of the agitator blades in a direction that is parallel to or perpendicular to an axial direction.
