Abstract
A combined regenerative scrubber and condensing heat exchanger system comprises a housing having an inlet and an outlet for channeling flue gas into and out of the housing. A first heat exchanger is located in the housing for contacting a downward flow of the flue gas for providing an initial cooling of the flue gas. The flue gas is channeled through a second heat exchanger in an upward direction for providing a further cooling of the flue gas. A reagent scrubbing spray device is used to spray reagent into the flue gas as well as onto the second heat exchanger for removing SO.sub.2 from the flue gas and for cleaning the second heat exchanger. A regeneration device is used to regenerate reagent from the reaction product as well as to recover SO.sub.2 from the reaction product.
