Abstract

Die Erfindung bezieht sich auf eine Kraftstoffeinspritzdüse für eine Gasturbinenbrennkammer, mit einem Filmleger 1, in dem mehrere Kraftstofföffnungen 2 ausgebildet sind. Die Erfindung zeichnet sich dadurch aus, dass die Mittelachsen 5 der Kraftstofföffnungen 2 durch den Filmleger 1 bezüglich ihrer radialen Ausrichtung im Wesentlichen parallel zur Hauptströmungsrichtung 6 der Luft angeordnet sind.

Figure imgaf001
The invention relates to a fuel injection nozzle for a gas turbine combustor, with a film former 1, in which a plurality of fuel openings 2 are formed. The invention is characterized in that the center axes 5 of the fuel openings 2 are arranged by the film feeder 1 with respect to their radial orientation substantially parallel to the main flow direction 6 of the air.
