Abstract

Beschrieben wird ein Brennersystem mit einem Vormischbrenner (1), in dem wenigstens ein Wirbel-Generator (2) vorgesehen ist, der von einer den Vormischbrenner (1) axial durchströmenden, Luft enthaltenen, gasförmigen Hauptströmung (ZL) durchsetzt wird, in die stromab des Wirbel-Generators (2) gasförmiger und/oder flüssiger Brennstoff als Sekundärströmung zur Erzeugung eines Brennstoff-/Luft-Gemisches eingedüst wird, sowie mit einer Brennkammer (5), die sich stromab des Vormischbrenners (1) an diesen anschließt und einen Brennkammerquerschnitt (C2) aufweist, der größer ist als der, durch den Vormischbrennner (1) begrenzten Strömungsquerschnitt (C1) unmittelbar stromauf zur Brennkammer (5).A burner system with a premix burner (1) is described in which at least one vortex generator (2) is provided, which is one of the Premix burner (1) which contains gaseous air flowing axially Main flow (ZL) is penetrated into the downstream of the vortex generator (2) gaseous and / or liquid fuel as a secondary flow for generation a fuel / air mixture is injected and with a combustion chamber (5), which connects downstream of the premix burner (1) and one Combustion chamber cross section (C2) which is larger than that through which Premix burner (1) limited flow cross-section (C1) immediately upstream to the combustion chamber (5).

Die Erfindung zeichnet sich dadurch aus, dass zwischen dem Vormischbrenner (1) und der Brennkammer (5) ein Strömungskanal (10) vorgesehen ist, der von Seitenwände begrenzt ist, die einen graduellen Übergang zwischen dem Strömungsquerschnitt (C1) und dem Brennkammerquerschnitt (C2) schaffen, und dass wenigstens eine Strömungsabrissstruktur (11) stromauf, innerhalb und/oder stromab des Strömungskanals (10) vorgesehen ist, durch die das durch den Strömungskanal (10) hindurchtretende Brennstoff-/Luft-Gemisch lokal von der Seitenwand des Strömungskanals (10) abgelöst wird.

Figure 00000001
The invention is characterized in that a flow channel (10) is provided between the premix burner (1) and the combustion chamber (5), which is delimited by side walls that allow a gradual transition between the flow cross section (C1) and the combustion chamber cross section (C2) create, and that at least one flow stall structure (11) is provided upstream, inside and / or downstream of the flow channel (10), through which the fuel / air mixture passing through the flow channel (10) locally from the side wall of the flow channel (10) is replaced.
