Abstract
Aufgabe der Erfindung ist es, einen Kegelbrenner für gasförmige und/oder flüssige Brennstoffe zu schaffen, der eine verringerte NOx- und Co-Emission aufweist. Erfindungsgemäss wird das dadurch erreicht, dass die Teilkegelkörper (1, 2) an ihrem stromabwärtigen Ende einen gemeinsamen Auslassdiffusor (27) besitzen. Sie weisen einen Übergangsbereich (28) zum Auslassdiffusor (27) auf, in dem die Grösse der Lufteintrittschlitze (7, 8) in Strömungsrichtung (3) kontinuierlich abnimmt. Der Auslassdiffusor (27) ist kreisrund und ohne Lufteintrittschlitze (7, 8) ausgebildet. The object of the invention is to provide a cone burner for gaseous and / or liquid fuels, which has a reduced NOx and Co emission. This is achieved according to the invention in that the partial cone bodies (1, 2) have a common outlet diffuser (27) at their downstream end. They have a transition area (28) to the outlet diffuser (27), in which the size of the air inlet slots (7, 8) decreases continuously in the direction of flow (3). The outlet diffuser (27) is circular and has no air inlet slots (7, 8).
