Abstract

Die Erfindung betrifft einen atmosphärischen Brenner mit einer Zufuhreinrichtung (1) für vorzugsweise gasförmigen Brennstoff, die mindestens eine Zufuhröffnung (2) aufweist, welche im we­ sentlichen zentral im Öffnungsbereich (3) eines stirnseitig offenen Rohres (5) angeordnet ist, wobei der Brennstoff unter Druck axial in das Rohr (5) einströmt und dabei Verbrennungs­ luft nach dem Venturiprinzip durch die Rohröffnung (4) ansaugt und gemeinsam mit der Verbrennungsluft aus einer sich am Ende des Rohres (5) anschließenden Brennerdüse (6) austritt.
Um einen Brenner vorzusehen, da trotz hoher Brennraumtempe­ raturen ein Rauchgas erzeugt, welches ohne weitere Behandlung und ohne Rauchgaswäsche deutlich verminderte NOx-Werte im Be­ reich von z.B. 100 mg/m³ erhält, wird erfindungsgemäß vorge­ schlagen, daß eine Rauchgasrückführleitung (16) im Öffnungs­ bereich des Rohres (5) mündet. The invention relates to an atmospheric burner with a feed device (1) for preferably gaseous fuel, which has at least one feed opening (2) which is arranged substantially centrally in the opening area (3) of a tube (5) which is open at the end, the fuel being below Axial pressure flows into the pipe (5) and thereby sucks combustion air through the pipe opening (4) according to the Venturi principle and emerges together with the combustion air from a burner nozzle (6) adjoining the end of the pipe (5).
In order to provide a burner, because despite high combustion chamber temperatures, a flue gas is generated which, without further treatment and without flue gas scrubbing, receives significantly reduced NO x values in the range of, for example, 100 mg / m³, the invention proposes that a flue gas return line (16) in Opening area of the tube (5) opens.
