Abstract
A multiple purpose burner process and apparatus in which a burner assembly having a burner member defining a burner throat bore extending therethrough and forming an ignition zone and at least one mixing zone in the burner throat bore, the total combustion air passing through the burner throat bore. A minor portion of fuel gas as ignition fuel produces a continuous ignition flame in the ignition zone, and plural meter channels extending through the burner member communicate with the mixing zone to pass an admixture of a diluent gas with the remainder portion of the fuel, as a primary fuel stream, to the mixing zone for forming with the remaining combustion air a primary fuel/diluent/combustion air mixture, and the primary fuel/diluent/combustion air mixture is ignited by the ignition flame in the mixing zone. Diluents can be internally recirculating flue gas or can be from an external source, and the flame envelope achieved by the burner assembly can be variously shaped for an industrial combustion application as required.
