Definitions

  • Disclosed embodiments are generally related to a fuel nozzle for use in a combustion turbine engine, such as a gas turbine engine and, more particularly, to a pre-mixing type of fuel nozzle that in one non-limiting application may be used in a distributed combustion system (DCS) injection system.
  • DCS distributed combustion system
  • the means to aerodynamically reduce the flow recirculation in a respective pre-mixing conduit 20 may comprise an inter-conduit passageway 24 arranged to provide fluid communication between the respective pre-mixing conduit 20 and a corresponding air flow conduit 22. It will be appreciated that the geometry of pre-mixing conduits 20 may be optionally configured to reduce flow recirculation in combination or in lieu of inter-conduit passageways 24.

Abstract

L'invention concerne un type de prémélange d'un injecteur de carburant (10) destiné à être utilisé dans un moteur à turbine à combustion. L'injecteur comprend un ensemble de conduits de prémélange (20) qui s'étendent entre une extrémité d'entrée (14) et une extrémité de sortie (16) d'un corps (12) de l'injecteur. L'injecteur peut en outre comprendre un ensemble de conduits d'écoulement d'air (22) disposés radialement vers l'intérieur par rapport à l'ensemble de conduits de prémélange. L'injecteur peut comprendre un passage entre les conduits (24) agencé de sorte à réduire de manière aérodynamique une recirculation d'écoulement dans l'ensemble de conduits de prémélange. Une structure de guidage de carburant (26) peut comprendre des éléments sans turbulence (28) pour diriger l'écoulement de carburant dans une direction radiale, chaque élément sans turbulence comprenant au moins un orifice (32) pour injecter l'écoulement de carburant dans la direction radiale dans un conduit de prémélange respectif pour prémélanger l'air et le carburant.
