Definitions

  • the invention relates to a burner with fuel mixing vortex generators and in particular the local improvement ⁇ tion of the mixture of air and fuel.
  • the uniform interference fuel into the Burn ⁇ voltage air is the central design task in the development of burners that operate mixed combustion in the area of so-called lean forward.
  • the temperature range of lean premix combustion is particularly useful in gas turbines because of the material-related limitation of the combustion chamber outlet temperature for controlling nitrogen oxide emissions.
  • the difficulty of premix combustion, especially under pressure, is the avoidance of uncontrollable combustion phenomena / self-ignitions within the premix, which are generally associated with the destruction of the premix.
  • the object of the invention is to provide a burner of the type mentioned, which is an improved mixture of air and fuel, in particular in the radially outer lie ⁇ the areas of Vormischumble enabled.
  • the invention solves this problem by providing that in such a burner with a substantially annular in cross-section, in the operation of air and fuel flow through the air supply and Vormischkanal formed by an outer shell and a hub and in the more

  • the invention proceeds from the realization that the locally present turbulence intensity represents an additional influence ⁇ parameter to the interference of the fuel in the air. Increasing the turbulence intensity acts mi ⁇ research demanding.
  • the turbulence is then locally increased in the form of a vortex street because of the shear.
  • the swirl blades are at least partially designed as hollow blades with outlet openings for fuel.
  • the air supply and premixing channel concentrically surrounds a central pilot burner system.
  • the local application demanding mixture by turbulence against each other "entangled" blade ends improves the Mi ⁇ research quality in the outdoor section without loading the inner richly influence. Furthermore, the mixing quality is more independent of the operating conditions.

Abstract

L'invention concerne un brûleur (1) pourvu d'un canal d'amenée d'air et de pré-mélange (4) sensiblement annulaire en section transversale et traversé pendant le fonctionnement par de l'air et un combustible. Ledit brûleur est formé par une enveloppe extérieure (5) et un moyeu (6), et plusieurs aubes de tourbillonnement (7) s'étendant dans la direction radiale du moyeu (6) à l'enveloppe extérieure (7) et présentant une surface de déviation (11) y sont agencées. Dans une zone extérieure radiale des aubes de tourbillonnement (7), un angle de fuite (alpha) par rapport à une direction d'écoulement principal (13) à une extrémité d'écoulement (12) de la surface de déviation (11) augmente au moins une fois et diminue au moins une fois dans la direction radiale.
