Description

Zündvorrichtung für mit flüssigem Brennstoff betriebene Drehzerstäuberbrenner Die Erfindung bezieht sich auf eine Zündvorrichtung mit elektrischem Glühdraht für mit flüssigem Brennstoff betriebene Drehzerstäuberbrenner. Als Zündvorrichtung für diesen Brennertyp wurden mit Ausnahme der Funkenzündung, die mehr für größere Brennerleistungen in Betracht kommt, lediglich Glühdrähte verwendet. Diese Vorrichtungen besitzen je- doch den Nachteil, daß sie mit verhältnismäßig hoher Leistung betrieben werden müssen, damit beim Start ein Kaltblasen der Drahtspirale vor Eintreten der Zündung verhindert wird. Nachdem insbesondere bei Fahrzeugheizgeräten nur eine beschränkte Leistung zur Verfügung steht, treten, insbesondere bei niedrigen Außentemperaturen, häufig Störungen auf, die sich nur schwer beseitigen lassen.Ignition device for rotary atomizer burners operated with liquid fuel The invention relates to an ignition device with an electric glow wire for rotary atomizer burners operated with liquid fuel. With the exception of spark ignition, which is more suitable for larger burner outputs, only filaments were used as the ignition device for this type of burner. These devices have JE but the disadvantage that they must be operated at a relatively high power so that the ignition is prevented when starting a cold blowing the wire spiral before entering. Since only a limited power is available, especially in the case of vehicle heaters, malfunctions often occur, especially at low outside temperatures, which are difficult to eliminate.

Mit der Erfindung soll nunmehr eine Zündvorrichtung mit geringem elektrischem Strombedarf geschaffen werden, die genauso einfach wie die bisher verwendeten Glühdralitzündungen ist.With the invention is now an ignition device with little electrical Electricity requirements are created that are just as easy as the glowdralite ignitions previously used is.

Diese Aufgabe wird durch den erfindungsgemäßen Vorschlag gelöst, nach dem man einen mit 8 bis 1.2 Volt betriebenen Glühdraht mit einer bei Zündvorrichtungen für andere Brennertypen an sich bekannten Mantelhülle umgibt, wobei diese im Sprühbereich des Drehzerstäubers angeordnet ist. Wie sich in eingehenden Versuchen herausgestellt hat, setzt sich auch nach längeren Betriebszeiten an der gegenüber der Drahtspirale großen Mantelfläche trotz der bei Drehzerstäubern gegebenen gröberen Zerstäubung kein Ruß an.This object is achieved by the proposal according to the invention, according to which a glow wire operated at 8 to 1.2 volts is surrounded by a casing known per se in ignition devices for other types of burners, which is arranged in the spray area of the rotary atomizer. As has been found in detailed tests, even after long periods of operation, no soot builds up on the outer surface, which is large compared to the wire spiral, despite the coarser atomization that occurs with rotary atomizers.

Für die Mantelhülle wird am zweckmäßigsten die Form eines Zylinders gewählt.The shape of a cylinder is most expedient for the jacket shell chosen.

In der Zeichnung ist schematisch die Anordnung und Form der erfindungsgemäßen Zündvorrichtung dargestellt.In the drawing, the arrangement and shape of the invention is schematically Ignition device shown.

Die im Zerstäubungsbereich des Drehzerstäubers 1 liegende Zündvorrichtung wird hier durch einen an eine nicht dargestellte Batterie angeschlossenen Glühdraht 2 gebildet, der von einer Mantelhülle 3 abgedeckt ist, die in besonders vorteilhafter Weise gleichzeitig eine der Zuleitungen des GlUhdrahtes 2 darstellt. Der den Drehzerstäuber 1 antreibende Elektromotor 4 treibt gleichzeitig ein Verbrennungsluftgebläse 5 an, so daß neben dem vom Drehzerstäuber 1 abgesprühten Brennstoff auch Verbrennungsluft gegen die Zündvorrichtung geführt wird. Die Zündvorrichtung wird dabei am zweckmäßigsten an einer Stelle angeordnet, die von dem durch die Projektion der Endkante des Drehzerstäubers 1 auf die Brennkammer gebildeten Kreis nicht mehr als der 1,5fache Durchmesser des Drehzerstäubers entfernt ist.The ignition device located in the atomization area of the rotary atomizer 1 is formed here by a glow wire 2 connected to a battery (not shown), which is covered by a jacket 3 which, in a particularly advantageous manner, simultaneously represents one of the supply lines of the glow wire 2. The electric motor 4 driving the rotary atomizer 1 simultaneously drives a combustion air blower 5 so that in addition to the fuel sprayed by the rotary atomizer 1 , combustion air is also directed towards the ignition device. The ignition device is most expediently arranged at a point which is not more than 1.5 times the diameter of the rotary atomizer away from the circle formed by the projection of the end edge of the rotary atomizer 1 onto the combustion chamber.
