Figur 1 zeigt ein Brennerelement 10 eines nicht näher
dargestellten atmosphärischen Gasbrenners. Der
atmosphärische Gasbrenner besteht aus einer Anzahl von
parallel nebeneinander angeordneten Brennerelementen 10.
Über die Anordnung einer entsprechenden Anzahl von
Brennerelementen 10 läßt sich die Brennerleistung beliebig
erhöhen.FIG. 1 shows a
Das Brennerelement 10 hat ein aus zwei schalenförmigen
Blechhälften 11, 12 gebildetes Gehäuse 14 sowie
brennraumseitig eine als Firstleiste ausgebildete
Brennerplatte 16 mit Gemischaustrittsöffnungen 18, wobei im
Ausführungsbeispiel gemäß Figur 1, 2 und 3 die Brennerplatte
16 gewölbt ausgebildet ist.The
Jedes Brennerelement 10 weist zwei Mischrohre 20
(Injektoren) mit jeweils einer Lufteintrittsöffnung 21,
einem Strömungskanalabschnitt 23 und einem Diffusorabschnitt
25 auf. Der Strömungskanalabschnitt 23 weist an einer Stelle
35 den engsten Querschnitt des Mischrohres 20 auf. Die
Lufteintrittsöffnungen 21 dienen zum Einleiten von
Primärluft, wobei jeder Lufteintrittsöffnung 21 eine Gasdüse
27 zugeordnet ist. Über die Gasdüse 27 wird das Brenngas in
das Mischrohr 20 eingedüst.Each
Ab der Stelle 35 erweitert sich der Strömungskanalabschnitt
23 zum Diffusorabschnitt 25 hin leicht konisch. An den
Strömungskanalabschnitt 23 schließt sich in
Strömungsrichtung des Brenngas-Luft-Gemischs der
Diffusorabschnitt 25 an. Die Diffusorabschnitte 25
verbreitern sich jeweils symmetrisch zu einer durch die
Mittellinie der Mischrohre 18 verlaufenden Ebene 28 in
Richtung der Breitseite des Brennerelements 10
kontinuierlich in Form einer parabelähnlichen Erweiterung
29. Die Erweiterung 29 des einen Mischrohres vereinigt sich
mit der Erweiterung 29 des benachbarten Mischrohres an einer
Stelle 31, so dass beide parabelähnlichen Erweiterungen 29
in eine gemeinsame Verteilkammer 30 münden. Die
Verteilkammer 30 ist der Brennerplatte 16 und den
Gemischaustrittsöffnungen 18 vorgeschaltet und erstreckt
sich im Wesentlichen über die Ausdehnung der Brennerplatte
16.From the
Die Diffusorabschnitte 25 weisen jeweils gemäß Figur 3 eine
den Querschnitt in Bezug auf die Schmalseite des
Brennerelements 10 verengende Einschnürung 32 auf, die im
Wesentlichen symmetrisch zu einer durch die Mittellinie
verlaufenden Ebene 33 ausgebildet ist. Links und rechts von
der Einschnürung 29 bilden sich zwei Diffusorkanäle 40 aus,
deren Strömungsquerschnitte größer sind als der
Strömungsquerschnitt der Einschnürung 29 an einer beliebigen
Stelle. Dadurch wird eine gleichmäßige Gemischverteilung in
der Verteilkammer 30 über die gesamte Erstreckung der
Gemischaustrittsöffnungen 18 erzielt. The
Wesentlich ist, dass die Fläche der
Gemischaustrittsöffnungen 18 und die Strömungsverhältnisse
des Brenngas-Luft-Gemischs in den beiden Mischrohren 20 so
aufeinander abgestimmt sind, dass die Wärmebelastung an den
Gemischaustrittsöffnungen 18 der Brennerplatte 16 ≤ 300
W/cm2 beträgt. Zur Erzielung der geringen Flächenbelastung
bzw. Wärmebelastung an den Gemischaustrittsöffnungen 18 der
Brennerplatte 16 wurden die Gemischaustrittsöffnungen 18 und
die Mischrohre 20 entsprechenden dimensioniert, wobei die
Fläche der Gemischaustrittsöffnungen 18 etwa dem 3-5fache
der gesamten Querschnittsfläche der Mischrohre 20 an der
engsten Stelle 35 entspricht. Durch diese geometrischen
Bedingungen wird Einfluß auf die Strömungsgeschwindigkeit
des Brenngas-Luft-Gemisches in den Mischrohren 20 genommen,
wobei eine höhere Strömungsgeschwindigkeit des Brenngas-Luft-Gemisches
eine höhere Flächenbelastung bzw.
Wärmebelastung bedeutet. Außerdem beträgt bei dem in Figur 1
dargestellten Brennerelement 10 die Breite B etwa dem 1,5-2fache
der Höhe H. Die Auslegung ermöglicht zudem ein
deutlich geringere Gesamthöhe H gegenüber vollvormischenden
GasbrennernIt is essential that the surface of the mixture outlet openings 18 and the flow conditions of the fuel gas-air mixture in the two
Es wurde weiterhin ermittelt, dass eine homogene Mischung
von Brenngas und Primärluft vom Verhältnis von
Mischrohrlänge L und Mischrohrquerschnitt abhängt, wobei die
Mischrohrlänge L etwa das 4-5fache des Durchmessers an der
engsten Stelle 35 des Mischrohres 20 beträgt.It was further determined that a homogeneous mixture
of fuel gas and primary air from the ratio of
Mixing tube length L and mixing tube cross-section depends, with the
Mixing tube length L about 4-5 times the diameter at the

Brennerelementen 10 zeigt Figur 4. Zwischen den
Brennerelementen 10 ist ein Spalt zur Zuführung von
Sekundärluft mit einer Breite X ausgebildet, wobei die
Breite X etwa 1/2 bis 1/5 der Tiefe Y der Brennerplatte 16
beträgt. Aufgrund dieser Dimensionierung wird über den
gesamten Modulationsbereich des atmosphärischen Gasbrenners
eine ausreichende Sekundärluftzuführung erzielt, wodurch
eine vollständige Verbrennung gewährleistet wird. Über die
Sekundärluftzuführung findet außerdem eine Kühlung des

Ausführungsbeispiel gemäß Figur 7 ist der den Querschnitt im
Bereich der Erweiterung 29 verengende Abschnitt von der
Schmalseite des Brennelements 10 betrachtet als ein
verengender Kanal 36 ausgebildet, der symmetrisch zu der
