Abstract

Bei einem Brenner zum Betrieb einer Brennkammmer mit einem flüssigen und/oder gasförmigen Brennstoff (12, 16) wird die dazu benötigte Verbrennungsluft (7) durch tangentiale Lufteintrittskanäle (5, 6) in einen Innenraum des Brenners geführt. Durch diese Strömungsführung entsteht im Innenraum eine Drallströmung, welche am Ausgang des Brenners eine Rückströmzone induziert. Um die sich dort bildende Flammenfront zu stabilisieren, wird bei jedem den Brenner bildenden Teilkörper (1, 2) mindestens eine Zone (27) vorgesehen, innerhalb welcher Eintrittsöffnungen (29) für die Eindüsung einer Zusatzluft (32) in die Drallströmung (7a) vorgesehen sind. Durch diese Eindüsung bildet sich an der Innenwand der Teilkörper (1, 2) einen Film, welcher verhindert, dass die Flamme entlang der Innenwand der Teilkörper (1, 2) in den Innenraum des Brenners zurückschlagen kann.

In the case of a burner for operating a combustion chamber with a liquid and / or gaseous fuel (12, 16), the combustion air (7) required for this purpose is conducted through tangential air inlet ducts (5, 6) into an interior of the burner. This flow control creates a swirl flow in the interior, which induces a backflow zone at the burner outlet. In order to stabilize the flame front formed there, at least one zone (27) is provided in each partial body (1, 2) forming the burner, within which inlet openings (29) are provided for the injection of additional air (32) into the swirl flow (7a) are. As a result of this injection, a film forms on the inner wall of the partial bodies (1, 2), which prevents the flame from striking back into the interior of the burner along the inner wall of the partial bodies (1, 2).
