Abstract
An air sparger assembly for a flue gas desulfurization wet scrubber agitation tank that eliminates the need for a mixer and reduces the amount of piping required. The air sparge pipes are arranged to be concentric with the agitation tank. A single main header provides air to the air sparge pipes. The discrete location of the air discharge holes in the sparge pipes utilizes the buoyant energy of the oxidation air to mix the slurry in the agitation tank.
