Title (EN) PILOT BURNER WITH AXIAL SWIRLERS FOR A GAS TURBINE
(FR) BRÛLEUR À FLAMME PILOTE À COUPELLES DE TURBULENCE AXIALES POUR TURBINE À GAZ
Abstract:
(EN) It is described a pilot burner (1) for a gas turbine (12), comprising an annular base body (2) with a fuel inlet pipe (5), an air inlet pipe (6) and a mixture outlet pipe (3) connected at a connection section (7). Said fuel inlet pipe (5) and said air inlet pipe (6) comprise separate means (8, 9) for axially swirling of the transported media, e.g. embodied as helical grooves and/or fins (8) in the inlet pipes (5, 6) or embodied as a helically shaped part (9) of said inlet pipes (5, 6). Furthermore, a gas turbine (12) comprising a compressor (13), a combustion chamber (14), a turbine (15) and a pilot burner (1) of the kind above is disclosed.
(FR) La présente invention concerne un brûleur à flamme pilote (1) destiné une turbine à gaz (12), comprenant un corps de base (2) annulaire muni d'un tuyau d'admission (5) de carburant, d'un tuyau d'admission (6) d'air et d'un tuyau de sortie (3) de mélange raccordé au niveau d'une section de raccordement (7). Ledit tuyau d'admission (5) de carburant et ledit tuyau d'admission (6) d'air comprennent des moyens séparés (8, 9) permettant de soumettre à une turbulence axiale les milieux transportés, adoptant par exemple la forme de rainures et/ou d'ailettes (8) hélicoïdales dans les tuyaux d'admission (5, 6) ou adoptant la forme d'une partie de forme hélicoïdale (9) desdits tuyaux d'admission (5, 6). La présente invention concerne en outre une turbine à gaz (12) comprenant un compresseur (13), une chambre de combustion (14), une turbine (15) et un brûleur à flamme pilote (1) du type susmentionné.
