ABSTRACT:
Contaminants such as sulfur oxides are removed from flue gas in a low pressure drop, turbulent mixing zone, vertical dry scrubber by channeling the flue gas through a low pressure drop gas distribution means which controls flue gas introduction to the scrubber, along with control of reagent introduction, by treating the flue gas with a finely atomized alkali solution or slurry reagent preferably from a single or multiple array of dual-fluid atomizers. The atomizers create a turbulent mixing zone downstream of the gas distribution means which results in a homogeneous distribution of the alkali solution or slurry reagent in the flue gas. Control means are provided for creating and maintaining the turbulent mixing zone. A transition at the bottom of the dry scrubber is used to entrain any particulates and/or spray dried materials in the bulk gas stream exiting the dry scrubber.
