Abstract
A process and apparatus for reducing the concentration of pollutants in an effluent from the combustion of a fuel or waste material is presented. The process and apparatus enables injection of an effluent treatment fluid at low treatment fluid flow rates yet provides an even dispersion of treatment fluid within an effluent passage with little or no clogging. An atomization conduit, positioned coaxially within a treatment fluid supply conduit, extends into the effluent and supplies an atomization fluid, such as steam or air. A treatment fluid is supplied through a supply conduit and through at least one jet in the atomization conduit wall at a velocity of between 2-60 feet per second, causing atomization of the treatment fluid within the nozzle.
