Brennermundstück für Gas- and Ölbrenner sowie für kombinierte Gas-ÖlbrennerBurner mouthpiece for gas and oil burners as well as for combined gas-oil burners

Bei Gas- und Örbrennern besteht für den Konstrukteur immer die "besondere Aufgabe, dafür zu sorgen, daß sich die Flamme nicht abheben kann.In the case of gas and oil burners, the designer always has the "special task to ensure that the flame cannot be lifted out.

Bei Gasbrennern tritt das Problem vor allem bei Gasen mit niederen Zündgeschwindigkeiten auf. So ist z.B. bei Erdgas, das mit einem normalen Druck von 2oo mmWS aus der Leitung kommt, die Zündgeschwindigkeit wesentlich kleiner, als die Ausströmgeschwindigkeit. Die Aufgabe der Flammenstabilisierung besteht sowohl für die Konstruktion von atmosphärischen, als auch Gebläsegasbrennern, ebenso auch bei Ölbrennern.In the case of gas burners, the problem occurs above all with gases with low ignition speeds. For example, with natural gas that with a normal pressure of 2oo mm water column comes out of the line that Ignition speed much lower than the outflow speed. The task of flame stabilization exists both for the construction of atmospheric, as well as Blower gas burners, as well as oil burners.

Bei Gasbrennern und bei Ölbrennern gibt es verschiedene Systeme, um die Flamme am Brennermundstück zu halten, z.B. Stauscheiben, Stauringe, Drallscheiben u.a., aber auch Halteflammen, die getrennt mit geringer Austrittsgeschwindigkeit um die Wurzel der | Hauptflamme angeordnet werden.There are different systems for gas burners and oil burners, to keep the flame on the burner mouthpiece, e.g. baffles, baffle rings, swirl disks, etc., but also holding flames that separate around the root of the | Main flame can be arranged.

Alle diese Einbauten sind umständlich oder erzeugen Widerstände .All of these internals are cumbersome or create resistance .

Die nachstehend beschriebene Ausbildung des Brennerkopfes ist außerordentlich einfach und eignet sich gleichermaßen für alle Gase und für öl.The design of the burner head described below is extremely simple and is equally suitable for all gases and for oil.

Sie besteht darin, daß der von der Aerotechnik her bekannte und oft beschriebene Coanda-Effekt nun auch für die Flammenstabili- ■ierung an Gaa- und ölbrennern auegenützt wird.It consists in the fact that the Coanda effect, known and often described from aerotechnology, is now also used for flame stabilization on gas and oil burners.

Die Strömung des austretenden Brenngas-Gemisches muß möglichst laminar sein. Deshalb sind DrallfTügel und ähnliche Turbulenz erzeugende Einbauten mit Ausnahme der unbedingt notwendigen Zündelektroden, der Ölleitung ,a.ä. zu vermeiden.The flow of the exiting fuel gas mixture must be as laminar as possible. That is why swirl wings and Similar turbulence-generating internals with the exception the absolutely necessary ignition electrodes, the oil line, etc. to avoid.

An dem nach außen gewölbten Hand (a ) der Brennermündung besteht nach diesem Effekt die Haftneigung des in der äußeren Zone austretenden turbulenzarmen Brenngases. Es wird schon brennend nach außen umgelenkt und beschleunigt, bis es abreißt und Wirbel bildet und um die Wurzel der Hauptflamme herum einen turbulenten Hing brennenden Gasgemisches erzeugt.On the outwardly curved hand (a) of the burner muzzle According to this effect, there is a tendency for the low-turbulence fuel gas exiting in the outer zone to adhere. It is already burning deflected outwards and accelerated until it breaks off and forms eddies and around the root of the Main flame around a turbulent hung-burning gas mixture generated.

Die Flamme des Brenners entsteht in der Zone (b), etwa in Höhe der Pfeilspitzen der Abbildung. Die von (b) bis (c) reichende Flammenzone wirkt wie eine Halteflamme und verhindert mit Sicherheit jedes Abheben der Hauptflamme. Der Coanda-Effekt wird um. so stärker, je glatter der gewölbte Rand der Brennermühdung ist.The flame of the burner arises in zone (b), approximately in Height of the arrowheads in the figure. The flame zone from (b) to (c) acts like a holding flame and prevents with certainty every lifting of the main flame. The Coanda Effect is around. the stronger, the smoother the arched one The edge of the burner fatigue is.
