Abstract

Bei einem Brenner der Doppelkegelbauart zum Verbrennen von flüssigen (12) und gasförmigen Brennstoffen (16) überlappen sich die mindestens zwei Teilkegelkörper (1, 2) zumindestens teilweise, wobei der Überlappungswinkel (δ) in Strömungsrichtung des Brenners zunimmt und gleichzeitig mit Zunahme des Überlappungswinkels (δ) der Abstand der Brennstoffinjektoren (15) von der Lufteintrittsebene (21) in den Brenner zunimmt. Dadurch fallen die Lufteintrittsebene (21) und die Brennstoffinjektionsebene (22) nicht mehr zusammen. Mit der Erfindung wird eine bessere Vormischung des gasförmigen Brennstoffes (16) mit der Verbrennungsluft erreicht, was zu geringeren NOx-Emissionen des Brenners und zu einer geringeren thermischen Belastung der Brennerfront führt.
