    摘要： A feed arm for a multiple circuit fuel injector of a gas turbine engine. The feed arm includes an elongated tubular sleeve having a central bore with an interior wall defining an inner diameter, and an elongated fuel tube positioned within the bore of the tubular sleeve. The fuel tube includes a tubular wall defining an outer diameter, which is substantially equal to the inner diameter of the central bore. A primary fuel flow passage is formed within the tubular wall of the fuel tube and bounded by the interior wall of the tubular sleeve, and the primary fuel flow passage circumferentially extends around the fuel tube at least once along the axial length of the fuel tube. A secondary fuel flow passage extends through a central portion of the fuel tube, and the fuel tube is configured to facilitate heat transfer by conduction and/or convection.

    摘要： A combustor for an industrial turbine includes a single transition piece transitioning directly from a combustor head-end to a turbine inlet. The transition piece includes an inner surface and an outer surface. The inner surface bounds an interior space for combusted gas flow from the combustor head-end to the turbine inlet. The outer surface at least partially defines an area for compressor discharge air flow. The transition piece includes a plurality of apertures configured to allow compressor discharge air flow into the interior space. Each of the plurality of apertures extends from an entry portion on the outer surface to an exit portion on the inner surface.

    摘要： A fuel injection system is provided for a gas turbine, comprising a mains airblast fuel injector having an annular shape, and inner and outer mains swirlers for swirling air past the mains airblast fuel injector. The inner and outer mains swirlers are concentric with the mains airblast fuel injector and are located radially inwardly and radially outwardly of the mains airblast fuel injector, respectively. The mains airblast fuel injector and the inner and outer mains swirlers are so arranged as to produce a fuel spray stream which expands from the mains airblast fuel injector and has a double flame front. The double flame front comprises flame fronts on both the radially inner and radially outer surfaces of the fuel spray stream.
