ABSTRACT:
A spray reactor for flue gas desulfurization, particularly suitable for steam generators, uses an atomizing disc to spray an alkaline reagent into the flue gas. Concentric inner and outer annular passages around the disc convey the flue gas, the outer passage flow being controlled by a series of dampers adapted to maintain a relatively constant flow velocity in the inner passage in response to turndown of the generator load.
