Abstract

Ein System enthält mehrere Vielrohr-Brennstoffdüsen (94), die jeweils mehrere Rohre (192) aufweisen, die sich in einer axialen Richtung erstrecken, wobei jedes Rohr (192) von den mehreren Rohren (192) einen Lufteinlass, einen Brennstoffeinlass und einen Brennstoff-Luft-Mischungsauslass aufweist, und ein Brennstoffdüsengehäuse (56) mit einer Aussenwand (120), die sich in Umfangsrichtung um eine Mittelachse (41) erstreckt, mehreren radialen Wänden, die sich von der Aussenwand (120) nach innen zu der Mittelachse hin erstrecken, mehreren Brennstoffdüsenaufnahmen (190), die innerhalb der Aussenwand (120) angeordnet sind, wobei die mehreren radialen Wände die mehreren Brennstoffdüsenaufnahmen (190) voneinander trennen und die mehreren Vielrohr-Brennstoffdüsen (94) in den mehreren Brennstoffdüsenaufnahmen (190) angeordnet sind, einer Befestigungsstruktur, die mehrere radiale Stützarme (124) aufweist, die sich von der Aussenwand (120) nach aussen erstrecken.
