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.A premix burner (11) consists essentially of at least two nested in the direction of flow Partial cone bodies (12, 13), their respective cone axes opposite a central axis (10) are offset. This will tangential slots (16) for the combustion air (9) are formed.

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.

Figure 00000001
Starting from the tip of the partial cone body (12, 13) is arranged a feed lance (1) which extends downstream into the interior of the premix burner (11) and runs essentially symmetrically to the central axis (10). At least one fuel nozzle (8) is arranged at the downstream end of the feed lance (1).
