Description
Dlit hochgespanntem Wechselstrom geheizter Dampfkessel. Die Heizung von Dampfkesseln mit hochgespanntem Wechselstrom geschieht meist unter Benutzung eines Teiles des Kesselwassers selbst als Heizwiderstand, indem man in einem unter Wasser liegenden, beiderseits offenen Isolierrohr zwei Elektroden anbringt, zwischen denen der Strom durch das Wawer übertritt, wobei sich die stromdurchflossene Wassersäule erhitzt und einen mehr oder weniger raschen Umlauf des flüssigen Kesselinhalts durch das Rohr verursacht. Um nun die Verdampfung des Wassers außerhalb des Isolierrohres im freien Kesselraum stattfinden zu ,lassen, hat man vorgeschlagen, die Strömung des Wasseis durch das Rohr durch eine besondere, einen Überdruck liefernde Umlaufpumpe zu beschleunigen. - . -Es ist ferner vorgeschlagen worden, die Mündung des Rohrs über . die Wasserfläche hervorragen zu lassen und das Wasser in einem Strähl gegen eine schirm- oder glockenförmige Fläche zu spritzen, die aus leitendem-Stoff besteht und mit dem einen Netzpol verbunden ist. Auch hier erfolgt die Verdampfung selbst weniger im Innern des Wasserstrahls als vielmehr im freien Kesselraum.Steam boiler heated by high voltage alternating current. The heating system of steam boilers with high-voltage alternating current is usually done using part of the boiler water itself as a heating resistor by placing it in an under Water lying, on both sides open insulating tube attaches two electrodes, between which the current through the Wawer crosses, whereby the water column through which the current flows heated and a more or less rapid circulation of the liquid contents of the kettle caused the pipe. Now to the evaporation of the water outside the insulating tube It has been suggested that the flow should take place in the open boiler room of the water ice through the pipe by a special circulation pump that provides positive pressure to accelerate. -. -It has also been suggested the mouth of the pipe above . to let the water surface protrude and the water in a stream against To spray an umbrella-shaped or bell-shaped surface made of conductive material and is connected to one power pole. Here, too, the evaporation takes place itself less inside the water jet than in the open boiler room.
Da sowohl dein freien Strahl als auch der schirmförmigen Elektrode Nachteile anhaften, die die Betriebssicherheit gefährden, wird nach der Erfindung das senkrecht stehende, die stromführende Wassersäule enthaltende Isolierrohr, in welches von oben die eine, von unten die andere Elektrode hineinragt, über den Wasserstand des Kessels hinausgefeirt und das Wasser oberhalb des Kesselwasserstandes längs einer Fläche ausgebreitet, um dem Wasser sofort nach seiner größten Er-'hitzung eine möglichst große, freie Oberfläche zu geben und so seine Verdampfung zu fördern. In dem Isolierrohr wird das Wasser durch eine besondere Pumpe, die außerhalb des Kessels angeordnet ist, hochgedrückt. .As both your free beam and the umbrella-shaped electrode Adhering to disadvantages that endanger operational safety, according to the invention the vertical insulating tube containing the current-carrying water column, in which one electrode protrudes from above and the other electrode from below, above the water level of the boiler and the water above the boiler water level lengthways an area spread around the water immediately after its greatest heating to give as large a free surface as possible and thus promote its evaporation. In the insulating tube, the water is drawn by a special pump that is outside the Kessel is arranged, pushed up. .
In der Zeichnung sind zwei Ausführungsbeispiele für die Erfindung dargestellt. Nach Fig. x wird das Wasser dem oberen, wärmsten Teil des Kesselinhalts entnommen und durch die Pumpe c in das im Innern des Kessels a befindliche Rohr b aus elektrisch nicht leitendem Material gedrückt. In. dieses Isolierrohr ragen von unten und oben die Elektroden d und e hinein, deren Abstand mittels Schraubenspindel f von außen einstellbar ist, zum Zweck, die Kesselleistung zu verändern. Das Isolierrohr b ragt über den Kesselwasserstand erheblich hinaus, und ihm gegenüber liegt die glockenförmige Fläche g, an welcher das durch b hochgetriebene heiße Wasser entlang läuft, so daß es eine, verhältnismäßig große Oberfläche bildet.Two exemplary embodiments of the invention are shown in the drawing. According to Fig. X, the water is taken from the upper, warmest part of the boiler contents and pressed by the pump c into the inside of the boiler a tube b made of electrically non-conductive material. In. This insulating tube protrudes from below and above the electrodes d and e, the distance of which can be adjusted from the outside by means of a screw spindle f, for the purpose of changing the boiler output. The insulating tube b protrudes considerably beyond the boiler water level, and opposite it is the bell-shaped surface g, on which the hot water driven up by b runs along, so that it forms a relatively large surface.
Nach Fig. 2 breitet sich das Wasser auf einer tellerartigen Platte h aus, die sich an das ollere Ende des Isolierrohres b anschließt. Diese könnte auch zur Vergrößerung der Oberfläche des abtropfenden Wassers mit Löchern versehen sein.According to Fig. 2, the water spreads on a plate-like plate h from, which connects to the ollere end of the insulating tube b. This could also provided with holes to enlarge the surface of the dripping water be.
Zur Regelung der Kesselleistung kann man auch die Geschwindigkeit des Wasserumlaufs heranziehen, dabei ist jedoch zu beachten, daß die größte Dampfausbeute nicht bei größter Umlaufsgeschwindigkeit erreicht wird, sondern daß es für jeden Elektrodenabstand -eine günstigste Umläufsgeschwindigkeit des Wassers gibt.The speed can also be used to regulate the boiler output the water circulation, but it should be noted that the greatest steam yield is not reached at the highest speed, but that For each electrode distance there is a most favorable circulation speed of the water gives.
Der Kessel nach der Erfindung kann sowohl für einphasigen als auch für mel@rphasigen Wechselstrom gebaut werden. Im letzteren Falle kann die Fläche, längs der sich das Wasser ausbreitet, mehreren Phasen gemeinsam angehören, indem sie sich an die Ausmündung mehrerer Elektroden verschiedener Phasen enthaltender Isolierröhren anschließt.The boiler according to the invention can be used both for single-phase and be built for mel @ rphasigen alternating current. In the latter case, the area along which the water spreads belong to several phases in common, in that they are attached to the junction of several electrodes of different phases Insulating tubes connects.
