Abstract

Die Erfindung betrifft einen Vormischbrenner (10) für eine Gasturbine, in Form eines Doppelkegelbrenners, welcher zwei ineinander verschachtelt angeordnete Teilkegelschalen (11, 12) umfasst, die zwischen sich Lufteintrittskanäle (18, 19) bilden, durch die von aussen Verbrennungsluft (20) in einen kegelförmigen Innenraum (30) des Vormischbrenners (10) einströmt, wobei an den Aussenwänden der Lufteintrittskanäle (18, 19) quer zur Strömungsrichtung der Verbrennungsluft (20) verlaufende, lineare Lochreihen von Eindüsungsöffnungen (21) angeordnet sind, durch welche ein gasförmiger Brennstoff (22) in die quer dazu vorbeiströmende Verbrennungsluft (20) eingedüst wird.The invention relates to a premix burner (10) for a gas turbine, in the form of a double - cone burner, which comprises two sub - cone shells (11, 12) arranged in a nested arrangement, which form between them air inlet channels (18, 19) through which combustion air (20) flows from outside a conical interior (30) of the premix burner (10) flows in, wherein on the outer walls of the air inlet ducts (18, 19) transverse to the flow direction of the combustion air (20) extending, linear rows of injection holes (21) are arranged, through which a gaseous fuel ( 22) is injected into the combustion air (20) flowing past transversely thereto.

Eine Verbesserung in der Durchmischung von Brennstoff und Verbrennungsluft und eine Reduktion der Schadstoffemissionen werden dadurch erreicht, dass die Eindüsungsöffnungen (21) jeweils ein Durchmesserverhältnis von Durchmesser der Eindüsungsöffnung zu effektivem Austrittsdurchmesser des Vormischbrenners aufweisen, der zwischen 0.011 und 0.015 liegt.An improvement in the mixing of fuel and combustion air and a reduction in pollutant emissions are achieved in that the injection openings (21) each have a diameter ratio of diameter of the injection port to effective exit diameter of the premix burner, which is between 0.011 and 0.015.

Die Erfindung betrifft weiter ein Verfahren zum Nacharbeiten von derartigen Vormischbrennern
