Title (EN) MULTI-FUEL INJECTOR HAVING SEPERATE AIR - PREMIXING STRUCTURES FOR THE PLURALITY OF FUELS AND A CONSEQUENT COMMON MIXING STRUCTURE BEFORE THE NOZZLE OUTLET
(FR) PROCÉDÉ ET APPAREIL POUR ISOLER DES PASSAGES DE FLUIDE INACTIFS
Abstract: front page image
(EN)A system includes a turbine engine having a fuel injector (100). The fuel injector (100) includes fluid ducts (103,105,107), each having a fuel inlet (108,110,212) coupled to a distinct fuel source. The system includes a compressed air source that provides compressed air simultaneously to the fluid ducts (103,105,107), and a convergence point (106) where combined fuel and air streams from the ducts are mixed. The fuel inlets (108,110, 112) are in a parallel flow arrangement such that no fuel from one fuel inlet (108,110,212) is present at another fuel inlet (108,110,212)
(FR)L'invention porte sur un système qui comprend un moteur à turbine ayant un injecteur de carburant. L'injecteur de carburant comprend des conduits de fluide présentant chacun une entrée de carburant accouplée à une source de carburant distincte. Le système comprend une source d'air comprimé qui fournit de l'air comprimé simultanément aux conduits de fluide, et un point de convergence où des courants combinés de carburant et d'air arrivant des conduits sont mélangés. Les entrées de carburant sont dans un arrangement d'écoulement parallèle de telle sorte qu'aucun carburant provenant d'un injecteur de carburant n'est présent dans un autre injecteur de carburant.
