A process and apparatus for reducing the concentration of pollutants in an effluent from the combustion of a fuel is presented. The process and apparatus enables injection of an effluent treatment fluid at independently variable droplet sizes and distance of injection to a wide variety of distribution patterns within an effluent passage. An atomization conduit, positioned coaxially around a treatment fluid conduit, extends into the effluent and supplies an atomization fluid. The supply conduit is axially slidable with respect to the atomization conduit and supplying a treatment fluid through the supply conduit. The relative axial position of supply conduit and the atomization conduit is adjusted and the rate of flow of the atomization fluid is selected to inject droplets of a size effective to a desired distance within the passage.
