Definitions

  • components are exposed to direct contact with a flame. This applies in particular to burner and combustion chamber components of a gas turbine. Although the direct contact of the burner or combustion chamber components with the flame should ideally not occur, it can not be avoided, for example, when a flashback occurs. In direct contact of the flame with burner components or combustion chamber surfaces, the materials of the burner are exposed to such high thermal loads that the material can be damaged.
  • hitherto high-temperature resistant materials such as Hastelloy X
  • Hastelloy X are used.
  • these materials provide a longer shelf life of the burner components, but provide no protection against temperatures of up to 1,400 0 C.
  • ceramic coatings and air film cooling are used. In the latter case, a boundary layer is created by air inflow, in which the fuel-air mixture is diluted so much that the fuel content is below the ignition limit and thus the risk of spreading of the flame is reduced to the burner or combustion chamber components.
  • the inventive method for protecting a surface from contact with a flame is characterized in that the surface to be protected is coated with an inert gas.
  • the surface to be protected may be the surface of a burner component or of a combustion chamber component of a gas turbine. Above all, the combustion chamber wall of a gas turbine can be effectively protected with the present method.
  • An interte gas is a gas which is very inert, meaning that it only takes part in a few chemical reactions.
  • the inert gas used in the present process may be, for example, water vapor, nitrogen, carbon dioxide or a noble gas such as helium, argon, neon, krypton, radon or xenon.
  • the inert gas used in the context of the present invention may also be a mixture of the gases mentioned.
  • the use of nitrogen or carbon dioxide is advantageous since their use is associated with the least cost.
  • the surface to be protected may be coated with the inert gas such that the inert gas is directed onto the surface through openings located in the surface to be protected.
  • the openings may be bores which extend at right angles to the surface to be protected or, in particular, at an angle thereto, at an angle to the latter.
  • the inert gas in the direction of flow of this fluid along the surface to be protected. This can be done in particular by openings in the form of obliquely arranged to the surface holes.
  • the fluid may be, for example, fuel or a Act fuel-air mixture.
  • the fuel can be hydrogen.
  • Fuel-air mixture a flow direction predetermined. It is therefore useful to protect the surface of the combustion chamber wall against direct contact with the burner flame in such a way that the inert gas is injected into the combustion chamber along the surface of the combustion chamber wall in the direction of this flow direction.
  • possibly existing film cooling holes can be used as injection openings.
  • the coating according to the invention of the endangered components or the endangered surfaces with a boundary layer of an inert gas means that oxygen is not present as oxidizer.
  • oxygen is not present as oxidizer.
  • An air film cooling is due to the large ignition range of hydrogen not suitable for this purpose.
  • Another advantage of the present invention is that it reduces the thermal stress on the components and thus extends their life.
  • FIG. 1 shows schematically a section through a part of a combustion chamber wall or a burner wall of a gas turbine.
  • FIG. 1 shows schematically a Section through a part of a combustion chamber wall or burner wall 1 of a gas turbine.
  • a fuel-air mixture 2 Inside the combustion chamber is a fuel-air mixture 2.
  • the flow direction of this fuel-air mixture 2 is indicated by an arrow 3.
  • the directed to the inside of the combustion chamber surface 7 of the combustion chamber wall 1 has an opening 6 which extends obliquely to the surface 7.
  • an inert gas 4 is passed into the interior of the combustion chamber.
  • the flow direction of the inert gas 4 is indicated by arrows 5.
  • an interface 8 is formed between the inert gas 4 introduced into the combustion chamber and the fuel-air mixture 2 located in the combustion chamber.
  • the fuel-air mixture 2 is burned via one or more flames.
  • a direct contact of the flame with the surface 7 of the combustion chamber wall 1 should be avoided.
  • an inert gas 4 is introduced into the combustion chamber via the opening 6, which is located in the combustion chamber wall 1.
  • the direction of flow 3 of the fuel-air mixture 2 causes the inert gas 4 to flow parallel to the flow direction 3 along the surface 7, thereby covering the surface 7 with a protective layer. Since the inert gas 4 is very inert and in particular contains no oxidizer such as oxygen, the flame in the combustion chamber can not reach the surface 7.
  • the opening 6 may be, for example, a film cooling hole. Moreover, as shown in FIG. 1, the opening can run obliquely to the surface 7, but also perpendicularly or at any other angle.
  • the inert gas 4 introduced into the combustion chamber through the opening 6 may be, for example, water vapor, nitrogen, carbon dioxide or a noble gas. As noble gases helium, argon, neon, krypton, radon or xenon are considered.
  • the presented in the present invention method provides effective protection of the surfaces of particular burner or combustion chamber components of a gas turbine against direct contact with a flame The thus caused protection against high temperatures reduces the thermal load on the components and thus extends their life.
