Abstract
An improved apparatus and method for spraying a liquid into a flue gas provides a boundary layer of gas along a perimeter of a dry scrubber housing to prevent deposition of wet material on the sidewalls thereof. The boundary layer of gas includes the use of heated air, particulate free flue gas, and/or dust laden flue gas. The system is operated at/or near the saturation temperature to further increase removal efficiencies and reagent utilization.
