Description
Einrichtung zum Entzünden von Heizöl an der Ausspritzdüse von Ölheizungsanlagen. Gegenstand der vorliegenden Erfindung ist eine Einrichtung zum Entzünden von Heizöl an der Ausspritzdüse von Ölhei- zungsanla.gen, welche dadurch gekennzeichnet ist, dass eine aus Widerstandsdraht beste hende Heizwendel, welche unter der Einwir kung einer elektrischen Spannung von höch stens 8 Volt glüht, an der Ausspritzdüse an geordnet ist.
Dadurch, dass eine niedere oltige Heiz wendel angestrebt wird, ergibt es sich notwen digerweise, dass ein entsprechend dicker Wi derstandsdraht verwendet werden muss, um eine vorbestimmte Heizleistung verrichten zu können.
Deshalb wird eine derartige Heiz wendel entsprechend weniger leicht durch die Wirkung der entstehenden Ölflamme beschä digt, so dass die Einrichtung betriebssicher ist, während bei früher schon v orgeschlage- nen hoehohmigen Heizspiralen und Heizwen- deln stets Beschädigungen der Heizspiralen hzw. Heizwendeln eintraten. Auch die Ent zündung des Öls scheint nach den vorliegen den Ergebnissen durch eine niederolimige Heizwendel. besser gewährleistet zu sein.
In der Zeichnung ist ein Ausführungsbei spiel der Erfindung schematisch dargestellt. Das Rohr 1 ist an eine ölförderpumpe an geschlossen und endigt in einer Ausspritzdüse 2, aus welcher ein Öltropfenkegd 3 aus gespritzt wird.
In der Nähe der Düsenöffnung ist ein Transformator mit dem Eisenkern 4, der Pri- tnärwicklung 5 und der aus nur wenigen dik- ken Windungen bestehenden Sekundärwiek- hing 6 angeordnet. An den Klemmen 7 der. Sekundärwicklung ist eine Heizwendel 8 aus einem Draht aus einer Legierung, welche Chrom enthält, z.
B. Kanthaldraht , als Wi derstandsdraht von mindestens 1 mm Durch messer angeschlossen, welche in den Ölkegel 3 hineinreicht und unter @,irkung einer Spannung von 2 bis 4 Volt glühend wird und das Öl entzündet. Ein Schutzblech 9 dient zum Schutz der Wendel. An die Hochspan- nimgäeite ist. eine Heizwicklung 10 zur Vor heizung des Öls angeschlossen.
Device for igniting fuel oil at the nozzle of oil heating systems. The subject of the present invention is a device for igniting heating oil at the injection nozzle of oil heating systems, which is characterized in that a heating coil consisting of resistance wire, which glows under the influence of an electrical voltage of at most 8 volts, starts the injection nozzle is arranged on.
As a result of the fact that a lower, oily heating coil is sought, it is necessary that a correspondingly thick resistance wire must be used in order to be able to provide a predetermined heating output.
Therefore, such a heating coil is correspondingly less easily damaged by the action of the resulting oil flame, so that the device is operationally safe, while with previously proposed high-resistance heating coils and heating coils, the heating coils are always damaged. Heating coils entered. According to the available results, the ignition of the oil also appears to be caused by a low-molecular heating coil. to be better guaranteed.
In the drawing, a Ausführungsbei game of the invention is shown schematically. The pipe 1 is closed to an oil feed pump and ends in an injection nozzle 2, from which an oil droplet kegd 3 is injected.
A transformer with the iron core 4, the primary winding 5 and the secondary cradle 6 consisting of only a few thick turns is arranged in the vicinity of the nozzle opening. At terminals 7 of the. Secondary winding is a heating coil 8 made of a wire made of an alloy which contains chromium, for.
B. Kanthal wire, connected as a resistance wire of at least 1 mm diameter, which extends into the oil cone 3 and is glowing under a voltage of 2 to 4 volts and ignites the oil. A protective plate 9 serves to protect the coil. On the high voltage side is. a heating coil 10 connected for heating the oil before.
