Abstract

Die Erfindung bezieht sich auf einen Gasturbinenbrenner für eine Gasturbine mit einer Kraftstoffdüse, welche mit mehreren Kraftstoffaustrittsbohrungen (23) versehen ist, welche jeweils mit einer Kraftstoffleitung verbunden sind, durch welche selektiv Kraftstoff durchleitbar ist, dadurch gekennzeichnet, dass zwischen einzelnen Kraftstoffaustrittsbohrungen (23) unterschiedliche statische Drücke der Luftströmung zwischen Kraftstoffleitung mit Kraftstoffdurchfluss und Kraftstoffleitungen ohne Kraftstoffdurchfluss ausgebildet sind.
