Abstract: A system for eliminating mist from a flue gas while providing air toxic control includes a wet scrubber housing having an inlet at one of the housing for the entry of the flue gas and an outlet at an opposite end of the housing for the exit of the flue gas. Sprayers are located in the housing for spraying the flue gas with a cleaning liquid in order to remove contaminants from the flue gas. At least one heat exchanger is located in the housing above the sprayers in order to remove entrained contaminants from the flue gas by cooling the flue gas. The flue gas is channeled from the inlet past the collection trays, sprayers and heat exchanger prior to exiting the housing through the outlet. A mist eliminator is also provided for eliminating mist from the flue gas.

Abstract: A two-stage flue gas treatment condensing heat exchanger system allows for flue gas to be passed into a two-stage housing at an inlet of the housing. The flue gas is channeled downwardly through a first stage of the housing having a first condensing heat exchanger which cools the flue gas. The flue gas is then upwardly channeled in the housing through a second stage having a second condensing heat exchanger which is located near an outlet. A collection section is located between the first stage and the second stage of the housing for collecting liquids, condensate, particulate and reaction product. Steam is injected into the housing at a plurality of locations for enhancing particulate removal.
