Abstract

Die vorliegende Erfindung betrifft einen Brennkammerkopf einer Gasturbine mit einer im Wesentlichen ringförmigen äußeren Brennkammerwand 104 und zumindest einer im Wesentlichen ringförmigen inneren Brennkammerwand 107, mit mehreren um den Umfang verteilt angeordneten Brennern 106, dadurch gekennzeichnet, dass mehrere segmentartige, um den Umfang angeordnete Kopfelemente 201 vorgesehen sind, deren Anzahl der Zahl der Brenner gleich ist und welche sich in radialer Richtung zwischen der inneren Brennkammerwand 107 und der äußeren Brennkammerwand 108 sowie in Umfangsrichtung zwischen durch Brennermittelachsen 208 gebildete Radialebenen 209 erstrecken.
