Description

Dampfkessel mit elektrischer Beheizung durch Elektroden, bei dem zur Regelung des Widerstandes zwischen Elektrode und Gegenelektrode ein Isolierrohr vorgesehen ist und die im Innern des Isolierrohrs angeordnete Elektrode durch einen Flüssigkeitsstrahl gekühlt wird Dampfkessel mit elektrischer Beheizung durch Elektroden, bei dem zur Regelung des Widerstandes zwischen Elektrode und Gegenelektrode ein Isolierrohr vorgesehen ist und die im Innern des Isolierrohrs angeordnete Elektrode durch einen Flüssigkeitsstrahl gekühlt wird.Steam boiler with electrical heating by electrodes, in which for Regulation of the resistance between the electrode and the counter electrode an insulating tube is provided and the arranged inside the insulating tube electrode by a Liquid jet is cooled steam boiler with electrical heating by electrodes, for regulating the resistance between the electrode and the counter-electrode Insulating tube is provided and the electrode arranged in the interior of the insulating tube is cooled by a jet of liquid.

Die Erfindung bezieht sich auf einen Dampfkessel mit elektrischer Beheizung durch Elektroden, bei dem zur Regelung des Widerstandes zwischen Elektrode und Gegenelektrode ein Isolierrohr vorgeßehen ist und die im Innern des Isolierrohrs angeordnete Elektrode durch einen Flüssigkeitsstrahl gekühlt wird.The invention relates to a steam boiler with electric Heating by electrodes, in which to regulate the resistance between the electrode and the counter electrode is provided with an insulating tube and inside the insulating tube arranged electrode is cooled by a jet of liquid.

Bei Dampfkesseln dieser Art muß die im Innern des Isolierrohrs angeordnete Elektrode, weil diese nur einen geringen Umfang und daher eine große Flächenbelastung aufweist, durch einen Flüssigkeitsstrahl an> geströmt werden, um eine wirksame Kühlung und Spülung zu erzielen. Bisher wurde dieser Kühlstrahl so auf die Elektroden gerichtet, daß die dem größten Stromüborgang abgekehrte Seite angestrahlt wurde. Die stark belastete Seite war somit im Schatten des Kühlstromes, so daß die Kühlung an den meist beanspruchten Flächen nicht wirksam werden konnte.In the case of steam boilers of this type, the must be arranged inside the insulating tube Electrode, because this has only a small scope and therefore a large surface loading has to be flowed to> by a jet of liquid in order to provide effective cooling and to achieve flushing. So far, this cooling jet was directed at the electrodes in such a way that that the side facing away from the largest current transfer was illuminated. The strong loaded side was thus in the shadow of the cooling flow, so that the cooling on the mostly stressed areas could not be effective.

Dieser Nachteil wird nach der Erfindung dadurch vermieden, daß der Flüssigkeitsstrahl durch ein unmittelbar an der Elektrode mündendes Rohr auf die durch den Stromübergang belastete Seite der Elektrode gerichtet ist und daß zur Vermeidung von Kurzschlüssen mindestens der im Bereich von Elektrode und Gegenelektrode befindliche Teil des Strahlrohrs aus Isolierstoff besteht. Dadurch, daß der im Bereich von Elektrode und Gegenelektrode befindliche Teil des Strahlrohrs aus Isolierstoff besteht, werden Kurzschlüsse vermieden.This disadvantage is avoided according to the invention in that the Liquid jet through a tube opening directly at the electrode onto the by the current transfer loaded side of the electrode is directed and that to Avoidance of short circuits at least in the area of the electrode and counter electrode located part of the radiant tube is made of insulating material. By being in the area Part of the radiant tube made of insulating material from the electrode and counter-electrode short circuits are avoided.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch dargestellt. Im Elektrodenkessel i befindet sich die Tauchelektrode z, deren Stromzuführung 3 isoliert ist. Die Elektrode 2 ist durch einen nach unten oder oben verschiebbaren, aus Isolierstoff bestehenden Mantel q. von der Gegenelektrode 5 abgeschirmt. Zur Kühlung der Elektrode 2 wird dem Kessel entnom= mene Flüssigkeit durch die Pumpe 6 und die Leitung 7 von unten an die Elektrode herangeführt. Dadurch wird auch der an der Elektrode entstehende Dampf rascher abgeführt.The drawing shows an embodiment of the subject matter of the invention shown schematically. The immersion electrode is located in the electrode tank i z, whose power supply 3 is isolated. The electrode 2 is through one down or sheath that can be slid at the top and is made of insulating material q. from the counter electrode 5 shielded. Liquid is withdrawn from the boiler to cool the electrode 2 brought up to the electrode from below by the pump 6 and the line 7. Through this the vapor generated at the electrode is also dissipated more quickly.

Um die Kühlwirkung noch zu erhöhen, ist das Rohr 7, welches wegen Kurzschlußgefahr nicht zu nahe an die Elektrode :2 herangeführt werden kann, mit einer aus Isolierstoff bestehenden Verlängerung 8 versehen, deren Mündung sich unmittelbar an der Elektrode 2 befindet, so daß der Flüssigkeitsstrahl in unverminderter Stärke auf diese auftrifft.In order to increase the cooling effect, the pipe 7, which is because of Risk of short circuit not too close to the electrode: 2 can be brought with an extension 8 made of insulating material, the mouth of which extends directly located on the electrode 2, so that the liquid jet in undiminished strength meets this.

Durch die beschriebene Ausbildung, welche in ähnlicher Weise auch bei einem durch Mehrphasenstrom gespeisten Kessel angewendet werden kann, wird eine erhöhte Belastungsfähigkeit der Elektroden erreicht.By the training described, which in a similar way can be applied to a boiler fed by multiphase electricity, a increased load capacity of the electrodes achieved.
