  Verfahren zum Entleeren der ölführenden Brennerelemente bei   Ileizölfeuerungen.   



   Die Erfindung bezieht sich auf Heizölfeuerungen und betrifft ein Verfahren, um die der strahlenden Hitze des glühenden Schamottematerials der Feuerung ausgesetzten ölführenden Brennerelemente nach Abstellen der Feuerung zu entleeren. 



   Bekanntlich ist es bei allen Heizölfeuerungen, insbesondere beim Verfeuern des Heizöles mittels   Druckdüse,   von grosser Wichtigkeit, dass das Zerstäuberorgan stets sauber bleibt, da dessen Verschmutzen ein häufiges Reinigen bedingt und die Betriebssicherheit sowie die Betriebsbereitschaft beeinträchtigt. 
 EMI1.1 
 verursacht Verunreinigungen. 



   Ein weiterer Übelstand ist darin gelegen, dass das in der Heizschlange eingeschlossene Öl nach Abstellen der Feuerung bzw. nach Schliessen des Absperrventils nicht mehr zirkulieren kann und der strahlenden Hitze des glühenden Schamottematerials der Feuerung ausgesetzt ist. Dieses in der Heizschlange befindliche Öl zersetzt sich aber bei Überschreitung einer   Höchsttemperatur,   wird dabei fest und verlegt den Rohrquerschnitt. 



   Damit nun alle diese, die häufigsten Betriebsstörungen verursachenden Mängel nicht vorkommen können, wird nach Beendigung des Heizens   erfindungsgemäss,   wie folgt, verfahren :
Nach Abstellen der   Öldruckpumpe   1 der in der Zeichnung im Schnitt beispielsweise veranschaulichten Heizölfeuerung, wird die   ÖldruckpumFe   bei offenem Absperrventil 2 eine ganz kurze Zeit, etwa eine halbe Minute, in der dem Arbeitsgang entgegengesetzten Richtung angetrieben und dann erst das Absperrventil 2 geschlossen. Bei diesem Vorgang entsteht in der Heizschlange 3 und in dem Düsenrohr 4 eine Saugwirkung, durch welche der Olinhalt der beiden Brennerelemente 3,4 vollkommen entleert und so die ganze Anlage von unangenehmen Betriebsstörungen freigehalten wird. 



   PATENT-ANSPRÜCHE :
1. Verfahren zum Entleeren der ölführenden Brennerelemente bei Heizölfeuerungen, dadurch gekennzeichnet, dass das Öl nach Abstellung der Feuerung aus den der strahlenden Wärme ausgesetzten Brennerelementen (Heizschlange 3 und   Düsenrohr   4) abgesaugt wird.

  Procedure for emptying the oil-carrying burner elements in ileizölfurnungen



   The invention relates to heating oil firings and relates to a method for emptying the oil-carrying burner elements exposed to the radiant heat of the glowing fireclay material of the furnace after the furnace has been switched off.



   As is well known, in all heating oil systems, especially when burning the heating oil by means of a pressure nozzle, it is of great importance that the atomizer always remains clean, since its soiling requires frequent cleaning and impairs operational safety and readiness for use.
 EMI1.1
 causes pollution.



   Another disadvantage is that the oil trapped in the heating coil can no longer circulate after the furnace has been switched off or the shut-off valve has been closed and is exposed to the radiant heat of the glowing fireclay material of the furnace. However, this oil in the heating coil decomposes when a maximum temperature is exceeded, becomes solid and shifts the pipe cross-section.



   So that all of these defects, which cause the most frequent malfunctions, cannot occur, the procedure according to the invention after the end of heating is as follows:
After switching off the oil pressure pump 1 of the heating oil furnace illustrated in section in the drawing, the ÖldruckpumFe is driven for a very short time, about half a minute, in the direction opposite to the operation and only then is the shutoff valve 2 closed. During this process, a suction effect arises in the heating coil 3 and in the nozzle pipe 4, by means of which the oil content of the two burner elements 3, 4 is completely emptied and the entire system is thus kept free from unpleasant operational disturbances.



   PATENT CLAIMS:
1. A method for emptying the oil-carrying burner elements in heating oil systems, characterized in that the oil is sucked out of the burner elements (heating coil 3 and nozzle tube 4) exposed to the radiant heat after the combustion system has been switched off.

2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die Öldruckpumpe selbst zur Absaugung des Öles aus den Brennerelementen (3, 4) benutzt wird, indem diese nach Abstellung der Feuerung bei offenem Absperrventil (2) eine kurze Zeit in der dem Arbeitsgang entgegengesetzten Richtung angetrieben und hierauf erst das Absperrventil geschlossen wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. 2. The method according to claim 1, characterized in that the oil pressure pump itself is used to extract the oil from the burner elements (3, 4) by this after switching off the furnace with the shut-off valve (2) open for a short time in the direction opposite to the operation driven and only then the shut-off valve is closed. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
