Definitions

  • the subject matter disclosed herein relates to an injection apparatus and, more particularly, to an injection apparatus for attachment to an outer vessel disposed about an inner vessel formed to define a main flowpath.
  • a typical turbomachine such as a gas turbine engine, includes a compressor, a combustor and a turbine.
  • the compressor compresses inlet gas to produce compressed gas, which is transmitted to the combustor.
  • the compressed gas is mixed with fuel and combusted to produce high temperature fluids. These high temperature fluids are then directed to the turbine for power and/or electricity generation.
  • a transition piece may be disposed between the combustor and the turbine such that the high temperature fluids flow through the transition piece prior to entering the turbine.
  • LLI late lean injection
  • US 7000396 describes a combustor for a gas turbine including a combustor body having an aperture and a casing enclosing the combustor body and defining a passageway therebetween for carrying compressor discharge air. At least one injection tube supplies 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 having a plurality of openings 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.
  • an injection apparatus 10 is provided.
  • the injection apparatus 10 is attachable to an outer vessel 11, such as an impingement sleeve or a flow sleeve of an exemplary turbomachine transition piece.
  • the outer vessel 11 may be disposed about an inner vessel 12, which may be the turbomachine transition piece and may be formed to define a main flowpath 120.
  • high temperature fluids are produced in a combustor and directed toward a turbine by way of the turbomachine transition piece. The flow of the high temperature fluids thus proceeds along the main flowpath 120 of the inner vessel 12. It is, however, to be understood that the injection apparatus 10 may be attachable to other vessels in the turbomachine and/or other systems.
  • the injection apparatus 10 may be attachable to a forward end of the impingement sleeve (i.e., proximate to the axial injection flow sleeve), the aft end of the impingement sleeve or to a flow sleeve of the combustor.
  • the injection apparatus 10 includes a ring-shaped or annular base 20 and a tubular body 40.
  • the annular base 20 is configured to be fastened to the outer vessel 11 by one or more of bolting, welding, sealing and butt welding.
  • the annular base 20 has a first surface 21 that is formed to define an injection hole location 200 and a protrusion 25.
  • the protrusion 25 protrudes from an interior facing surface 26 of the annular base 20 and extends perimetrically about the injection hole location 200 such that the protrusion 25 is axisymmetric about a centerline of the inner vessel 12.
  • the protrusion 25 includes a first part 27 and a connector 30.
  • the first part 27 protrudes from the interior facing surface 26 such that the first part 27 is axisymmetric about the centerline of the inner vessel 12.
  • the connector 30 has a first end 31, which is configured to be fastened by, for example, welding to a distal end of the protrusion 25 perimetrically about the injection hole location 200, and a second end 32.
  • the first end 31 and the second end 32 supportively meet at bend 33, which may be angular or curved, such that the second end 32 defines a secondary injection hole location 201, which may correspond to the injection hole location 200.
  • the injection hole location 200 and the secondary injection hole location 201 may be round or, in some cases, substantially circular.
  • the protrusion 25, the connector 30 and the tubular body 40 may also have round or, in some cases, substantially circular cross-sections (i.e., they may be ring-shaped) in correspondence with the shape of the injection hole location 200 and the secondary injection hole location 201.
  • the tubular body 40 has sufficient length to extend across an annulus defined between the outer vessel 11 and the inner vessel 12 and has an interior facing surface 41 that is formed to define a tubular injection hole 400.
  • the tubular body 40 is sealably fastened to the first surface 21 of the annular base 20 at the injection hole location 200 by way of, for example, bolt 42 that engages with the annular base 20.
  • the tubular body 40 also has a protrusion 45 that may be sealably fastened to the second end 32 of the connector 30 at the secondary injection hole location 201. Seals 46, such as o-rings or c-seals, may be sealably disposed between the tubular body 40 and the first surface 21 and between the protrusion 45 and the second end 32 of the connector 30.
  • the tubular injection hole 400 permits fluid communication between an exterior of the outer vessel 11 and the main flowpath 120.
  • the tubular body 40 may include a flange 47.
  • the annular base 20 may include an exterior facing surface 28 that faces radially outwardly and away from the main flowpath 120. This exterior facing surface 28 may have a fastening surface 280 formed thereon at the injection hole location 200 where the exterior facing surface 28 is machined to be flat and/or smooth and therefore configured for mating with the flange 47.
  • bolt 42 is employed to fasten the tubular body 40 to the annular base 20, the bolt 42 extends through both the flange 47 and the fastening surface 280 of the exterior facing surface 28.
  • the tubular body 40, the connector 30, the protrusion 25 and the annular base 20 may cooperatively define a plenum 50.
  • the tubular body 40 is further formed to define an additional injection hole 401 for permitting fluid communication between an interior of the plenum 50 and the tubular injection hole 400.
  • the additional injection hole 401 may be defined as a plurality of additional injection holes 401, which are arrayed about the tubular injection hole 400 of the tubular body 40 at the plenum 50. Separation between adjacent additional injection holes 401 may be uniform or non-uniform.
  • the plenum 50 may be supplied with fuel and the exterior of the outer vessel 11 may include compressed air, such as compressor discharge air that is produced by a compressor of the turbomachine.
  • the compressed air flows through the tubular injection hole 400 and entrains a flow of the fuel from the plenum 50 into the tubular injection hole 400.
  • the fuel is thereby mixed with the compressed air and injected into the main flowpath 120 as a fuel/air mixture.
  • the injection apparatus 10 may be employed as part of an axially staged injection system of a turbomachine or, more particularly, as part of a late lean injection (LLI) system of the turbomachine.
  • the fuel/air mixture may be lean such that combustion of the fuel/air mixture within the main flowpath 120 serves to reduce the production and subsequent emission of pollutants, such as oxides of nitrogen (NOx).
  • NOx oxides of nitrogen
  • the annulus defined between the outer vessel 11 and the inner vessel 12 is generally supported by support structures 60, such as a-spacers arrayed about the inner vessel 12.
  • these support structures 60 may be disposed between an exterior facing surface of the inner vessel 12 and the interior facing surface 26 of the annular base 20.
  • the injection hole location 200 (and the accompanying structures as described above) may be provided as a plurality of injection hole locations 200.
  • the plural injection hole locations 200 may be arrayed about the outer vessel 11 and the inner vessel 12 as non-axisymmetric features. Separation between adjacent injection hole locations 200 may be uniform or non-uniform.
  • four injection hole locations 200 may be clustered about respective lower portions of the outer vessel 11 and the inner vessel 12.
