    Abstract: A combustor for a gas turbine includes a main fuel injector for receiving compressor discharge air and mixing the air with fuel for flow to a downstream catalytic section. The main fuel injector includes an array of venturis each having an inlet, a throat and a diffuser. A main fuel supply plenum between forward and aft plates supplies fuel to secondary annular plenums having openings for supplying fuel into the inlets of the venturis upstream of the throats. The diffusers transition from a circular cross-section at the throat to multiple discrete angularly related side walls at the diffuser exits without substantial gaps therebetween. With this arrangement, uniform flow distribution of the fuel/air, velocity and temperature is provided at the catalyst inlet.

    Abstract: According to various embodiments, a system includes a fluidization elbow. The fluidization elbow includes an elbow inlet, an elbow outlet downstream from the elbow inlet, and an elbow body disposed between the elbow inlet and the elbow outlet, wherein the elbow body turns and converges from the elbow inlet toward the elbow outlet. The fluidization elbow also includes multiple gas nozzles coupled to the elbow body, wherein the multiple gas nozzles include injection axes that generally converge toward the elbow outlet.

    Abstract: A combustor for a gas turbine includes a combustor body having an aperture and a casing enclosing the combustor body and defining a passageway therebetween for carrying compressor discharge air. There is at least one injection tube for supplying an amount of the compressor discharge air into the combustor body and the injection tube is disposed between the aperture and through the casing. A collar is disposed at the passageway and surrounds the injection tube so that the injection tube passes through the collar. A gap is disposed between the collar and the injection tube. The collar has a plurality of openings. A method for quenching combustion in a gas turbine includes supplying a fixed amount of compressor discharge air into a body of a combustor of the gas turbine and supplying a variable amount of compressor discharge air into the body. The fixed amount of compressor discharge air is disposed concentrically around the variable amount of compressor discharge air.
