Abstract

Ein Vormischbrenner (11), besteht im wesentlichen aus mindestens zwei in Strömungsrichtung ineinandergeschachtelten Teilkegelkörpern (12, 13), deren jeweilige Kegelachsen gegenüber einer Mittelachse (10) versetzt sind. Dadurch werden tangentiale Schlitze (16) für die Verbrennungsluft (9) gebildet.
Ausgehend von der Spitze der Teilkegelkörper (12, 13) ist eine sich stromabwärts ins Innere des Vormischbrenners (11) erstreckende Speiselanze (1) angeordnet, welche im wesentlichen symmetrisch zur Mittelachse (10) verläuft. Am stromabwärtigen Ende der Speiselanze (1) ist mindestens eine Brennstoffdüse (8) angeordnet.
