Definitions

  • the high temperature and pressure combustion gases are then expanded through a turbine to extract work so as to provide the required thrust or drive a generator depending on the application.
  • the turbine includes at least a single stage with each stage consisting of a row of blades and a row of vanes.
  • the blades are circumferentially distributed on a rotating hub with the height of each blade covering the hot gas flow path.
  • Each stage of non-rotating vanes is placed circumferentially, which also extends across the hot gas flow path.
  • the included invention involves the combustor of gas turbine engines and components that introduce the fuel and air into the said device.
  • US 2007/0107437 A1 describes a combustor.
  • the combustor includes a combustor liner and a swirl premixer disposed on a head end of the combustor liner and configured to provide a fuel-air mixture to the combustor.
  • the combustor also includes a plurality of tangentially staged injectors disposed downstream of the swirl premixer on the combustor liner, wherein each of the plurality of injectors is configured to introduce the fuel-air mixture in a transverse direction to a longitudinal axis of the combustor and to sequentially ignite the fuel-air mixtures from adjacent tangential injectors.
  • FIG. 2 also shows the general operation of the can in the example can-annular combustor configuration, where a pre-mixed fuel-air mixture 9 is injected into the cans 1 at an angle 8.
  • a flame 10 forms and travels through the can in a path 11 that follows the can liner.
  • These tangentially directed nozzles result in flames from each nozzle interacting with the downstream and adjacent nozzle. This key feature enhances ignition and reduces the need of piloting burner nozzles by allowing the flame from a nozzle to ignite the fuel at the adjacent and downstream nozzle.
