METHOD AND APPARATUS FOR COMBUSTING FUEL WITHIN GAS TURBINE ENGINE

PROBLEM TO BE SOLVED: To provide a proper system since a lean-lean start in a combustor may increase a local liner wall temperature near a premix fuel flame because of the disproportionate amount of premix fuel between fuel nozzles.SOLUTION: A nozzle 402 for channeling a fluid into a combustor assembly includes: a body 406 including a centerline; passageways 414, 416, 418 extending through the body along the centerline; and a nozzle tip 500 coupled to a downstream end of the passageways 414, 416, 418. The nozzle tip 500 has a radius extending from a center of the nozzle tip to an outer surface of the nozzle tip. The nozzle tip 500 includes a downstream face, and a plurality of outlet passageways that each include openings 424, 502 defined in the downstream face. Each of the openings 424, 502 includes respective X-, Y-, and Z-axes defined with respect to a tangent line, the radius, and the centerline. Each of the plurality of outlet passageways is at a discharge angle of greater than 30° measured with respect to the respective Z-axis in respective X-Z planes.
