ABSTRACT:
A system for introducing air into a slurry in a flue gas desulphurization process includes a stationary lance and an impeller. The lance include an outlet portion and a vane assembly. The outlet directs air away from the impeller. The vane assembly may produce turbulence and may convert a portion of the swirling flow from the impeller into longitudinal flow.
