Brenner mit flammenloser VerbrennungFlameless burners

Die Neuerung betrifft einen Brenner mit flammenloser Verbrennung, bei dem ein brennbares Gas-Luft-Gemisch durch eine perforierte keramische Platte hindurchgedrückt und an deren Oberfläche entzündet wird. Hinter dieser keramischen Platte befindet sich der Zuführungskanal für das brennbare Gas-Luft-Gemisch. Der Vorteil dieser Anordnung sind die flammenlose Verbrennung und ein homogenes Strahlungsfeld, welches durch Glühen der keramischen Lochplatte erzeugt wird.The innovation concerns a burner with flameless combustion, in which a combustible gas-air mixture passes through a perforated ceramic plate is pushed through and ignited on the surface. Behind this ceramic plate is the supply channel for the combustible gas-air mixture. Of the The advantages of this arrangement are the flameless combustion and a homogeneous radiation field, which is created by glowing the ceramic Perforated plate is generated.

Der Nachteil dieser Anordnung ist eine beschränkte Anwendungstemperatur , das die Wärmeleitfähigkeit der keramischen Platte mit zunehmender Temperatur besser wird uäd das von hinten mit konstantem Druck und konstanter Geschwindigkeit nachströraende Gas-Luft-Gemisch bei einer Stsahlungstemperatur von über 900° nicht mehr in der Lage ist, die in entgegengesetzter Richtung nach hinten wandernde Wärme abzuführen. Dies führt zu einem Rückschlagen der Flamme, d. h. an der Hinterseite der keramischen Lochplatte entsteht eine die Zündtemperatur des im Zuführungskanal befindlichen Gas-Luft-Gemisches entsprechende Temperatur. Abgesehen von der hierdurch entstehenden Explosionsgefahr in der Gas-Luft-Zuführung, sinkt die Strahlungsleistung der Oberfläche der keramischen Lochplatte.The disadvantage of this arrangement is a limited application temperature, which affects the thermal conductivity of the ceramic plate with increasing temperature, the flow from behind with constant pressure and constant speed improves Gas-air mixture at a steel temperature of over 900 ° is no longer able to dissipate the heat moving backwards in the opposite direction. This leads to a Flashback of the flame, d. H. at the back of the ceramic Perforated plate creates a temperature corresponding to the ignition temperature of the gas-air mixture in the feed channel. Apart from the resulting risk of explosion in the gas-air supply, the radiant power of the surface decreases the ceramic perforated plate.

Diese und andere Mängel werden gemäß der Neuerung bei einem wie eingangs erläuterten Brenner behoben durch ein in Strömungs-These and other deficiencies will be in accordance with the innovation at a as explained at the beginning, remedied by a flow

Auf diese Weise wird ein "negatives Wärmepotential" geschaffen, das durch das fortlaufende Durchströmen des Siebes mit dem noch unverbrannten Gas-Luft-Gemisch hervorgerufen wird. Es können dadurch höhere Temperaturen angewendet werden, während es ferner möglich ist, den Flammendurehschlag von der Hinterseite der Brennerplatte in den Zuführungskanal zu vermeiden.before
metal sieve arranged in the direction of «texsteXB of the ceramic plate. In this way, a "negative heat potential" is created, which is caused by the continuous flow of the still unburned gas-air mixture through the sieve. As a result, higher temperatures can be used, while it is also possible to prevent the flame from leaking into the feed channel from the rear of the burner plate.

Bei einer Ausführungsform der Neuerung ist vorgesehen, daß die offene Siebfläche größer ist als der freie Durchlaß der keramischenIn one embodiment of the innovation it is provided that the open screen area is larger than the free passage of the ceramic

In den Figuren 1 bzw. bedeuten 1 den Zuführungskanal für das brennbare Gas-Gemisch, mit einem Verteilerraum vor dem neuerungsgemäß vorgesehenen Metallsieb 3» das in Strömungsrichtung vor der perforierten keramischen Platte 4 angeordnet ist.An embodiment of the innovation is shown schematically in FIG attached drawing, reproduced.
