Abstract
Abstract An effluent control apparatus for receiving an effluent contaminated with a pollutant and reducing the pollutant content of the effluent discharged from the effluent control apparatus wherein the contaminated effluent is moved through a firing chamber maintained at a predetermined temperature level via a burner assembly, the contaminated effluent mixing with air and being heated to a predetermined temperature level generally within the firing chamber for combusting the combustible pollutant components contained in the contaminated effluent. Air is forced through an air inlet passageway and discharged in a direction generally parallel with the direction of flow of the effluent through the effluent control apparatus cooperatively pulling the effluent through the effluent control apparatus and enhancing the combustion of the combustible pollutant components within the firing chamber. A baffle having baffle openings is disposed within a portion of the firing chamber and heated to a predetermined temperature level, the baffle reducing the velocity of the effluent flow through the firing chamber and intimately contacting a portion of the effluent, the heated baffle cooperating to maintain the predetermined temperature level within the firing chamber.
