Abstract

Mischeinrichtung (10) für einen Brenner (100), die ein Brennerrohr (20), ein sich an das Brennerrohr (20) anschließendes Flammrohr(30) und einen in dem Brennerrohr (20) angeordneten Düsenstock (40) aufweist, wobei koaxial in dem Brennerrohr (20) axial fixiert eine Luftdüse (60) angeordnet ist, die sich in das Flammrohr (30) hinein erstreckt und Verbrennungsluft aus dem Brennerrohr (20) in das Flammrohr (30) führt, und wobei in einem Übergangsbereich zwischen dem Brennerrohr (20) und dem Flammrohr (30) Rezirkulationsöffnungen (85) angeordnet sind, wobei das Rezirkulationsmittel (70) vorgesehen sind, welche axial fixiert und um ihre Längsachse drehbar innerhalb des Übergangsbereichs angeordnet sind und ausgebildet sind, bei Drehung um ihre Längsachse einen Durchtrittsquerschnitt (86) der Rezirkulationsöffnungen (85) zu variieren.

Figure imgaf001
A mixing device (10) for a burner (100), which has a burner tube (20), a flame tube (30) adjoining the burner tube (20) and a nozzle rod (40) arranged in the burner tube (20), wherein coaxial in the Burner tube (20) axially fixed an air nozzle (60) is arranged, which extends into the flame tube (30) and combustion air from the burner tube (20) into the flame tube (30) leads, and wherein in a transition region between the burner tube (20 ) and the flame tube (30) recirculation openings (85) are arranged, wherein the recirculation means (70) are provided which are axially fixed and rotatable about its longitudinal axis within the transition region and are formed, upon rotation about its longitudinal axis a passage cross-section (86) the recirculation openings (85) to vary.
