Zwischen den nebeneinander angeordneten Brennerelementen 10 ist ein nicht dargestellter Spalt vorhanden, durch den zusätzlich Sekundärluft in eine sich oberhalb der Brennerplatte 15 ausbildende Brennzone strömt.The mixing tubes 13 each have an air inlet opening 21, each a gas nozzle, not shown assigned. The gas nozzles direct fuel gas into the Mixing tubes 13, which via the air inlet openings 21st Primary air entrains in the mixing tube 13, so that in the Mixing tubes 13 forms a fuel gas-air mixture. Between the burner elements 10 arranged side by side is a gap, not shown, available through the additional Secondary air in a above the burner plate 15th forming combustion zone flows.

An die Mischrohre 13 schließen sich jeweils Diffusorabschnitte 24 an, die in eine gemeinsame Verteilkammer 25 münden. Zur gleichmäßigen Verteilung des Brenngas-Luft-Gemischs ist der Strömungskanal des Diffusorabschnitts 24 mit einer deltaförmigen Verengung 27 ausgebildet. Im Bereich der Verteilkammer 25 bilden die Blechhälften 17, 18 einen umlaufenden, gehäuseseitigen Wandabschnitt 29 aus (Figur 5).The mixing tubes 13 are each connected Diffuser sections 24 at a common Distribution chamber 25 open. For even distribution of the Fuel gas-air mixture is the flow channel of the Diffuser section 24 with a delta-shaped constriction 27 educated. In the area of the distribution chamber 25 form the Sheet metal halves 17, 18 a circumferential, housing-side Wall section 29 from (Figure 5).

Die zu den Gasdurchtrittsöffnungen 16 weisenden oberen Sicken 38, 39 weisen dabei eine geringere Höhe auf als die von den Gasdurchtrittsöffnungen 16 entfernt angeordneten unteren Sicken 38', 39', wobei das Verhältnis der beiden Höhen zueinander maximal 1:2 betragen kann. Dieses Verhältnis ist bei Mischkörper 12 und Brennerplatte 15 gleich. Eine sichere Dichtung wird außerdem dadurch erzeugt, wenn die obere Sicke 38 der Brennerplatte 15 auf Nennmass mit einer positiven Toleranz und die untere Sicke 38' der Brennerplatte auf Pressung ausgelegt ist. Dadurch sind die Sicken 38, 38', 39, 39' derart aufeinander abgestimmt, dass diese im Zusammenwirken eine definierte Linienpressungen erzeugen, die jeweils Dichtkanten ausbilden. Dadurch wird in allen Betriebszuständen die geforderte Brenngasdichtheit gewährleistet.The beads 38, 38 ', 39, 39' have in the direction of insertion Burner plate on the mixing tube of different heights. The to the gas passage openings 16 facing upper beads 38, 39 have a lower height than that of Gas passage openings 16 located lower Beads 38 ', 39', the ratio of the two heights can be a maximum of 1: 2 to each other.
