摘要： A fuel injector is provided and includes a member defining a flowpath through which a first fluid flows, the flowpath having a cross-section with transverse elongate and short axes, a head defining a plenum storing a supply of a second fluid and a system fluidly coupled to the flowpath and the plenum to inject the second fluid from the plenum and into the flowpath at first and second locations along the elongate axis. The injected second fluid is formed into jets at the first and second locations, the first fluid entrains the jets such that the injected second fluid flows through the flowpath and mixes with the first fluid, and the short axis has a sufficient dimension such that the jets remain spaced from a sidewall of the member.

摘要： A secondary fuel nozzle includes a plurality of tubes axially extending downstream within the secondary fuel nozzle, the tubes defining passages operable to allow a flow of fluid to flow through each of the passages, the passages including an outermost tertiary passage and a radially inner secondary fuel passage. The secondary fuel nozzle also includes a fuel peg extending radially outward from the axially extending tubes, the fuel peg operable to emit a fluid radially outward therefrom. The secondary fuel nozzle further includes a crossover manifold attached to the fuel peg and in fluid communication with the radially inner secondary fuel passage and the fuel peg, wherein the crossover manifold is attached to the corresponding tubes that define the tertiary passage and the radially inner secondary passage by butt welds.

摘要： A seal assembly for use between an injector and a combustion chamber in a gas turbine. A liner at least partially defines the combustion chamber, and the liner has at least one tubular liner collar, through which an injector is inserted. In one embodiment, the liner collar has a partially convex outer diameter and a floating collar is positioned at least partially around the liner collar. The floating collar has a retention member having a first end fixed to the floating collar and a second end configured to abut the convex outer diameter of liner collar, wherein the retention member maintains the floating collar at a radial distance from the injector less than a radial distance between the liner collar and the injector.
