Abstract
A burner for a melter is provided which includes a nozzle, a fuel stream moving through the nozzle, and an oxidant stream including an initial elliptical cross section and being external to the nozzle and surrounding the fuel stream for providing a combustion stream having a cross section transitioning from an elliptical cross section to a circular cross section to provide a flat flame from the circular cross section for combustion in the melter. A method for producing a flat flame is also provided.
Claims14
A burner for a melter, comprising:
- a fuel nozzle having a fuel passage therein for a fuel stream and extending to a fuel nozzle tip having an elliptical cross section, the fuel nozzle constructed with the fuel nozzle tip transitioning to a circular cross section at a discharge orifice of said burner;
- and
- an oxidant passage surrounding the fuel passage and extending to an oxidant opening at the fuel nozzle tip, the oxidant opening having another elliptical cross section and being external to the fuel nozzle for transitioning from said another elliptical cross section to said circular cross section at said discharge orifice to provide a flat flame from the circular cross section for combustion in the melter.
A method of producing a flat flame from a nozzle for combustion in a melter, comprising:
- moving a fuel stream through the nozzle,
- moving an oxidant stream surrounding and external to the nozzle and having its major axis perpendicular to the fuel stream for having an elliptical cross section,
- converging the fuel stream with the oxidant stream for providing a combustion stream emitted from the nozzle having an elliptical cross section, and
- transitioning said combustion stream from said elliptical cross section to a circular cross section for providing a flame having a substantially flattened cross section for combustion in the melter.
