Description

Elektrodendampfkessel, dessen Elektroden als zylindrisch ineinandergreifende Hohlkörper Elektrodendampfkessel für Heizung mit Wechselstrom durch Elekiroden- unter Zuhilfenahme von die Rolle des Heizwiderstandes spielenden Flüssigkeitsstrahlen, die von einer Elektrode zur andern fließen, sind bekannt. Auch ist hierbei schon vorgeschlagen worden, außer einer primären Regelung des Flüssigkeitskreislaufes eine zusätzliche Regelung in der Weise erfolgen zu lassen, daß ein oben offenes, mit gestuftem Auslauf versehenes Gefäß vorgesehen ist, dessen Wasserstand und somit auch elektrischer Widerstand sich entsprechend der primären Regelung des Flüssigkeitskreislaufs einstellt. Während aber bei dieser bekannten Einrichtung die zusätzliche Regelung (ebenso wie die primäre) mittels frei laufender stromführender Flüssigkeitsstrahlen erfolgt, wobei nicht selten ein Verspritzen der Flüssigkeit gegen die Kesselwandung eintritt, erfolgt hier die zusätzliche Regelung in ruhendem Benetzkontakt an einer der beiden zur primären Regelung dienenden konzentrischen Elektroden, zwischen denen die aus der inneren Elektrode herausgedrückten Flüssigkeitsstrahlen für die primäre Widerstandsbildung maßgebend sind. Erfindungsgemäß ist nun die Einrichtung so getroffen, daß. die innere, als Zuführung des in der Menge regelbaren Elektrolyten dienende Elektrode mit einem sie konzentrisch umgebenden zylindrischen Aufnahmegefäß für den Elektrolyten verbunden ist, in dessen Mantel in verschiedener Höhe Auslauföjffnungen angeordnet sind, und daß auch in der inneren Elektrode in verschiedener Höhe Zulauföffnungen angebracht sind, die teilweise durch einen Regelkolben abdeckbar sind.Electrode steam boiler, the electrodes of which are cylindrically interlocking Hollow body electrode steam boiler for heating with alternating current through electrode with the aid of jets of liquid that play the role of heating resistance, which flow from one electrode to the other are known. Also here is already has been proposed, except for a primary control of the fluid circuit to allow an additional regulation in such a way that an open top, provided with a stepped outlet vessel is provided, its water level and thus electrical resistance also changes according to the primary regulation of the fluid cycle adjusts. But while in this known device, the additional regulation (as well as the primary one) by means of freely running current-carrying liquid jets occurs, whereby it is not uncommon for the liquid to splash against the boiler wall occurs, the additional regulation takes place here in dormant wetting contact on one of the two concentric electrodes used for primary regulation, between them the jets of liquid pressed out of the inner electrode for the primary Resistance formation are decisive. According to the invention, the device is now made so that. the inner one, serving as a feed for the electrolyte, which can be regulated in quantity Electrode with a concentrically surrounding cylindrical receptacle for The electrolyte is connected, in the jacket of which there are discharge openings at different heights are arranged, and that inlet openings are also in the inner electrode at different heights are attached, which can be partially covered by a control piston.

In der Zeichnung ist ein Ausführungsbeispiel eines solchen Heizkessels dargestellt.In the drawing is an embodiment of such a boiler shown.

a, b sind die den Heizstrom leitenden Elektroden, die im Dampfraum des Kessels liegen und die bei rohrförmiger Ausbildung gleichachsig zueinander angeordnet sind. Diese Elektroden sind mit einer Flüssigkeitsfördervorrichtung s in einen Flüssigkeitskreislauf geschaltet. Die innere Rohrelektrode a ist geloclit und mit einem Regulierschieber d versehen, der die Austrittsmenge des Wassers an der Elektrode a zu regeln hat. Die austretenden Wasserstrahlen spielen dabei in bekannter Weise die Rolle eines regelbaren elektrischen Heizwiderstandes, indem sie in mehr oder weniger großer Zahl gegen einen Kranz dachförmiger, sich übergreifender Ringe treffen, welche um die Elektrode a herum im Oberteil der Elektrode b vorgesehen sind und das Wasser zum gYoßen Teil auf-ihrer dachförmigen Mantelfläche herunterrieseln lassen. Die Elektrode b taucht mit ihrem unteren Endteil in ein oben offenes Wassersammelgefäß c ein, das mit der Elektrode a fest zusammenhängt und dessen Mantel mit einer Anzahl von Ausströmöffnungen c versehen ist. Dadurch wird erreicht, daß sich der Wasserstand w im Gefäß c in einem ganz bestimmten Verhältnis zu der mittels des Regulierschiebers d veränderlichen Wassermenge je nach der Anzahl und Größe der kataraktartig wirkenden Ausströmöffnungen e einstellt, wodurch an der Elektrode b und der Seitenwandung des Gefäßes c die wasserbenetzte, stromführende Oberfläche in mehr oder weniger großem Maße verändert wird und damit eine zusätzliche Widerstandsregelung zustande kommt. Das Wasser wird zudem gleichzeitig gezwungen, die Elektrode b gemäß der Pfeilrichtung unten zu umspülen, wodurch das Anhaften von Dampfblasen und damit eine unkonstante Stromaufnahme vermieden wird. a, b are the electrodes which conduct the heating current and which are located in the steam space of the boiler and which, if they are tubular, are arranged coaxially to one another. These electrodes are connected in a liquid circuit with a liquid delivery device s. The inner tubular electrode a is geloclit and provided with a regulating slide d, which has to regulate the amount of water discharged at the electrode a. The exiting water jets play the role of a controllable electrical heating resistor in a known manner by meeting a wreath of roof-shaped, overlapping rings in more or less large numbers, which are provided around the electrode a in the upper part of the electrode b and the water to Let the part trickle down on its roof-shaped outer surface. The lower end part of the electrode b is immersed in a water-collecting vessel c which is open at the top and which is firmly connected to the electrode a and the jacket of which is provided with a number of outflow openings c. This ensures that the water level w in the vessel c is set in a very specific ratio to the amount of water that can be changed by means of the regulating slide d, depending on the number and size of the cataract-like outflow openings e, whereby the electrode b and the side wall of the vessel c die water-wetted, current-carrying surface is changed to a greater or lesser extent and thus an additional resistance control comes about. The water is also forced at the same time to wash around the electrode b in the direction of the arrow below, whereby the adhesion of vapor bubbles and thus an inconsistent current consumption is avoided.
