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. In a burner of the double-cone type for burning liquid (12) and gaseous fuels (16), the at least two partial cone bodies (1, 2) overlap at least partially, the overlap angle (δ) increasing in the flow direction of the burner and at the same time as the overlap angle ( δ) the distance of the fuel injectors (15) from the air inlet plane (21) into the burner increases. As a result, the air inlet level (21) and the fuel injection level (22) no longer coincide. The invention achieves a better premixing of the gaseous fuel (16) with the combustion air, which leads to lower NOx emissions from the burner and to a lower thermal load on the burner front.
