Definitions

  • the present invention relates to a combustion chamber, in particular a tube combustion chamber, a gas turbine and a method for operating a combustion chamber and a gas turbine.
  • Modern gas turbines should meet the requirements in terms of pollutant emissions and environmental friendliness in a wide operating range. The fulfillment of these requirements depends essentially on the combustion system used in the gas turbine.
  • NOx nitrogen oxides
  • To reduce emissions of nitrogen oxides (NOx) lean premix is used.
  • high turbine inlet temperatures are sought to achieve a high efficiency, which are associated with high flame temperatures.
  • the aforementioned premixed flames are susceptible to thermoacoustic instabilities due to the high thermal power density and the NOx emissions increase exponentially with increasing flame temperature.
  • axial staging consists of a conventional burner that fires a primary combustion zone. This primary zone can in turn be internally graded like conventional burners and covers the load range up to today's firing temperatures. Downstream of the primary zone is followed by a secondary combustion zone. In this additional fuel is injected through an axially offset from the primary zone stage. This is then burned in a diffusion-like regime.
  • the fuel may be diluted with inert components (steam, nitrogen, carbon dioxide) to greatly lower the stoichiometric combustion temperature, thereby suppressing NOx formation.
  • inert components steam, nitrogen, carbon dioxide
  • the US 2011/0067402 A1 discloses a gas turbine with a combustion chamber having a dual stage combustion concept.
  • the combustor includes a combustor head end having a burner assembly, a combustor exit and a combustor wall, the combustor wall extending from the combustor head end to the combustor exit, and a primary zone and a secondary zone.
  • the secondary zone is located in the main flow direction of the hot gas downstream of the primary zone.
  • injectors opening into the secondary zone are arranged, which form a second axial stage of the combustion system.
  • a second object is to provide a corresponding gas turbine.
  • a third object of the present invention is to provide an advantageous method for operating a combustion chamber or a gas turbine comprising a combustion chamber, which makes it possible to reduce emissions of nitrogen oxides and / or to reduce CO emissions.
  • the first object is achieved by a combustion chamber according to claim 1.
  • the second object is achieved by a gas turbine according to claim 12.
  • the third object is achieved by a method according to claim 13.
  • the dependent claims contain further advantageous embodiments of the invention.
  • the combustion chamber according to the invention comprises a longitudinal axis, a combustion chamber head end and a combustion chamber exit.
  • the combustor further includes a combustor wall extending from the combustor head end to the combustor exit.
  • the combustion chamber according to the invention comprises a primary zone and a secondary zone.
  • the secondary zone is arranged in the main flow direction of the hot gas downstream of the primary zone.
  • the combustion chamber comprises at least one injector for introducing a fuel-air mixture into the secondary zone.
  • the injector is disposed in the secondary zone on the combustion chamber wall.
  • the injector also includes an outlet opening into the secondary zone or an injection opening with an inflow direction.
  • the inflow direction has a component in the circumferential direction of the combustion chamber.
  • the combustor wall includes an outer surface and at least one injector is at least partially helically disposed with respect to the longitudinal axis of the combustor along the outer surface.
  • the term "along the surface” also includes a first course of the injector spaced from the surface, so that the injector is in direct contact with the combustion chamber wall only in a section passing through the combustion chamber wall.
  • helical is also understood to be helical, for example helices of decreasing diameter, wherein the diameter of the helix may be essentially circular or elliptical.
  • the fact that the injector is at least partially helically disposed with respect to the longitudinal axis of the combustion chamber along the outer surface also includes such injectors that at least partially follow a portion of such a spiral or helical path.
  • a number of corresponding injectors are arranged on the combustion chamber wall in the region of the secondary zone.
  • the combustion chamber is preferably a tube combustion chamber. At least one burner may be arranged at the end of the combustion chamber.
  • the primary zone is determined by the area in which the fuel supplied via the burner is primarily burned within the combustion chamber.
  • the secondary zone is characterized by the fact that in it the hot gas generated in the primary zone is further burned out as completely as possible.
  • the secondary zone can in principle be arranged at any desired position between the primary zone and the combustion chamber exit.
  • the airborne axial stage itself has several advantages. By premixing fuel and air outside the combustion chamber as with conventional burner technology, the resulting peak temperatures and thus NOx emissions can be reduced. Lower residence times in the secondary zone and turbine entry continue to result in lower overall NOx emissions. In addition, no additional media are needed, but an operation takes place only with the originating from the compressor outlet air, which are treated with fuel in the axial stage to a mixture. Therefore, the resulting system is robust and stable available.
  • the Airborne axial stage therefore equally serves to expand the operating range of the combustion system to lower and higher loads.
  • the combustion chamber wall may comprise an outer surface. At least one injector may be disposed at least partially along the outer surface. This has the advantage that good utilization of the available installation space around the combustion chamber results in a large premix length in the injectors despite the compact design. Furthermore, emissions are reduced and thermoacoustic tuning is possible by adapting deadtime elements in flame transfer functions.
  • the present invention also has the following special advantages: Due to the helical arrangement, a long mixing length can be achieved in the injectors or scoops despite their compact design.
  • the swirl generation provides for the generation of additional gradients and shear layers and thus for a better mixing with the main flow.
  • a smoother turbine entry profile reduces emissions.
  • a simple and inexpensive construction of the guide vanes of the first turbine stage (TLe 1) is made possible.
  • the present invention opens up great potential for saving cooling air and possibly saving potential by dispensing with the vanes of the first turbine stage (TLe 1).
