Abstract

Bei einer Brennkammer einer Gasturbogruppe, welche im wesentlichen aus einer Mischstrecke (2) zur Vormischung eines Luft/Brennstoff-Gemisches (16) und einem nachgeschalteten Brennraum (3) besteht, wird am Uebergang zwischen den beiden genannten Durchflussstrecken (2/3) ein Querschnittssprung (5) vorgesehen. Dieser induziert den Durchflussquerschnitt des Brennraumes (3) und bildet zugleich äussere Rezirkulationszonen 10) im Brennraum (3). In der Endphase der Mischstrecke (2) zweigen Durchflusskanäle (4) ab, welche dann in die äusseren Rezirkulationszonen (10) münden. Durch diese Durchflusskanäle (4) strömt ein Teil (9) des Luft/Brennstoff-Gemisches aus der Mischstrecke (2) in die äusseren Rezirkulationszonen (10), wobei es hier mit einem zusätzlichen Brennstoff (6) angereichert wird. Dieser Brennstoff (6) wird über eine mit Bohrungen (18) versehene Ringleitung (19) eingebracht. Das abgezweigte Gemisch (9) stellt in den äusseren Rezirkulationszonen (10) eine selbstzündende Pilotflamme dar, welche die Flammenfront (20) wesentlich stabilisiert.
