Description

  

      Elektrisch    beheizte     Nesselanlage.       Die Erfindung bezieht sich auf eine Kessel  anlage, in welcher der Nutzdampf mit Hilfe  eines elektrisch beheizten, in einem geschlosse  nen     Kreislauf    strömenden Wärmeträgers er  zeugt wird.  



  Kesselanlagen dieser Art haben den Nach  teil, dass in dem geschlossenen Kreislauf  system infolge Dissoziation und Elektrolyse  Gase entstehen, die nicht     kondensierbar    sind  und den Kreislauf des Wärmeträgers stören.  



  Dieser Nachteil wird durch die Erfindung  vermieden. Sie besteht darin, dass das Kreis  laufsystem mit einer Entlüftungsvorrichtung  versehen ist, mittelst der die den Kreislauf  störenden Gase entfernt werden.  



  Ein Beispiel des     Erfindungsgegenstandes     ist auf der Zeichnung schematisch dargestellt.  Der mittelst der Elektroden 1 beheizte       Dampfkessel    2 erzeugt Dampf, welcher durch  die Leitung 3 zur Erzeugung von Nutzdampf  aus dem Speisewasser in den Nutzdampf  erzeuger 4 strömt. Aus diesem fliesst das  Kondensat des Heizdampfes durch die Lei  tung 5 wieder zurück zum Kessel 2. Die    Speisepumpe 7 fördert das für die Erzeugung  des Nutzdampfes notwendige Speisewasser  aus der Leitung 6 durch die Leitung 8 in  den     Nutzdampferzeuger    4, in welchem das  Wasser im Sinn der Pfeile 9 durch das  mittlere Rohr 10 abwärts strömt, um her  nach im Sinn der Pfeile 11 und 12 im In  nern der Rohre 13 wieder nach oben zu  steigen.

   Das Rohr 10 ist am obern Ende  trichterförmig erweitert, um das Wasser nur  mit einer geringen Geschwindigkeit einströ  men zu lassen, so dass keine Dampfblasen  in das Rohr 10 mitgerissen werden.  



  Der die äussere Seite der Rohre 13 um  gebende Heizdampf überträgt seine Wärme  an das im Innern der Rohre 13 befindliche  Wasser, kondensiert dabei und erzeugt im  Innern der Rohre den Nutzdampf, welcher  durch die Leitung 14 zu den Verbrauchs  stellen strömt.  



  Der     Nutzdampferzeuger    4 ist an der  höchsten Stelle des den Heizdampf enthal  tenden Raumes durch die Leitung 15 mit  der Entlüftungsvorrichtung 16 verbunden.      Dem diese Entlüftungsvorrichtung umgeben  den Kühlmantel 17 wird durch die Leitung  18 ein Kühlmittel zugeführt; das durch die  Leitung 19 wieder abgeführt wird. Das in  der Entlüftungsvorrichtung entstandene Kon  densat strömt durch die Leitung 20 in den       Heizdampferzeuger    2 zurück, während die  nicht     kondensierbaren    Gase durch die     mit-          telst    des Organes 21 verschliessbare Leitung  22 der Entlüftungsvorrichtung entnommen  werden.

   Verluste, welche sich im Kreislauf  des Wärmeträgers ergeben, werden durch  Hinzufügen von frischer Flüssigkeit durch die  mittelst des Organes 24 abschliessbare Lei  tung 23 wieder ersetzt.  



  Die Entnahme der nicht     kondensierbaren     Gase aus der Entlüftungsvorrichtung kann  auch selbsttätig durch besondere Vorrich  tungen,     beisuielsweise    in Abhängigkeit vom    Druck oder von einer andern Zustandsgrösse  des     Heizmittelkreislaufes    erfolgen. Als Wärme  träger für den     Reizmittelkreislauf    können  Wasser, in besonderen Fällen aber auch andere  Stoffe verwendet werden. Ebensogut können  zur Erzeugung von Nutzdampf ausser Wasser  auch andere     Stoffe    verwendet werden.



      Electrically heated nettle system. The invention relates to a boiler system in which the useful steam with the help of an electrically heated, in a closed circuit flowing heat carrier it is generated.



  Boiler systems of this type have the disadvantage that in the closed circuit system, as a result of dissociation and electrolysis, gases arise that are not condensable and disrupt the circuit of the heat carrier.



  This disadvantage is avoided by the invention. It consists in that the circulation system is provided with a venting device, by means of which the gases that interfere with the circulation are removed.



  An example of the subject matter of the invention is shown schematically in the drawing. The steam boiler 2 heated by means of the electrodes 1 generates steam which flows through the line 3 to generate useful steam from the feed water into the useful steam generator 4. From this, the condensate of the heating steam flows through the Lei device 5 back to the boiler 2. The feed pump 7 conveys the feed water necessary for the generation of the useful steam from the line 6 through the line 8 into the useful steam generator 4, in which the water in the sense of Arrows 9 through the middle tube 10 flows downwards to her after in the sense of arrows 11 and 12 in the nern of the tubes 13 to rise again.

   The tube 10 is widened in a funnel shape at the upper end in order to allow the water to flow in only at a low speed so that no steam bubbles are entrained into the tube 10.



  The heating steam around the outer side of the tubes 13 transfers its heat to the water located inside the tubes 13, condenses in the process and generates the useful steam inside the tubes, which flows through the line 14 to the consumption points.



  The useful steam generator 4 is connected to the ventilation device 16 through the line 15 at the highest point of the space containing the heating steam. To which this ventilation device surrounds the cooling jacket 17, a coolant is fed through the line 18; which is discharged again through line 19. The condensate produced in the venting device flows back through the line 20 into the heating steam generator 2, while the non-condensable gases are removed through the line 22 of the venting device, which can be closed by means of the organ 21.

   Losses that arise in the circuit of the heat carrier are replaced by the addition of fresh liquid through the line 23 which can be closed by means of the organ 24.



  The non-condensable gases can also be withdrawn from the venting device automatically by special devices, for example as a function of the pressure or another variable of the heating medium circuit. Water, but in special cases also other substances, can be used as heat carrier for the irritant circuit. Substances other than water can just as well be used to generate useful steam.
