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.
