Description

Elektrisch beheizter Dampfkessel. Die Erfindung betrifft einen elektrisch beheizten Dampfkessel, bei welchem das zu verdampfende Wasser durch eine Rohrleitung den aus Rohren mit geringem Fassungsvermögen bestehenden Heizkörpern zugeführt wird, welche durch die elektrischen Widerstandsdrähte beheizt werden.Electrically heated steam boiler. The invention relates to an electric heated steam boiler, in which the water to be evaporated through a pipe is fed to radiators made of small-volume pipes, which are heated by the electrical resistance wires.

Bei den bisher bekannten Bauarten dieser Kessel stand der Dampfraum des Kessels in unmittelbarer offener Verbindung mit dem Wasservorratsraum, der noch dazu außerhalb des eigentlichen Kessels angeordnet war. Im Gegensatz hierzu ist bei der vorliegenden Erfindung- der Dampfraum gegen den Wasservorratsraum völlkommen abgeschlossen. Dieser abgeschlossene Dampfraum, in dem die röhrenförmigen Heizkörper angeordnet sind, bildet also einen in sich geschlossenen Behälter, der innerhalb des Wasserraumes angeordnet ist, so daß Strahlungsverluste vermieden werden. Die Zuführung des Speisewassers zu den Heizkörpern erfolgt durch eine mit selbsttätig wirkenden Absperrorganen versehene Rohrleitung, die sich öffnet, sowie der Dampfdruck in dem Kessel nachläßt.In the previously known designs of these boilers, the steam room stood of the boiler in direct open connection with the water storage room, which is still this was arranged outside the actual boiler. In contrast to this is in the present invention - the steam space against the water storage space completely closed. This closed steam room in which the tubular radiator are arranged, so forms a self-contained container, the inside of the water space is arranged so that radiation losses are avoided. the The feed water is supplied to the radiators automatically by a with acting shut-off devices provided pipeline, which opens, as well as the steam pressure subsides in the boiler.

Die Zeichnung stellt einen Längsschnitt durch einen elektrischen Heizkessel dar. Der Heizkessel besteht aus dem äußeren, mit Wasser gefüllten Kessel a und dem inneren Zylinder b, der die Heizkörper c aufnimmt. Die Heizkörper sind bekannter und beliebiger Bauart und mit Hilfe der Muttern g leicht auswechselbar in dem Boden d befestigt. Die Heizkörper tragen in der Mitte ein Rohr h, das durch die Leitungen l und m mit dem Wasserraum des Kessels a in Verbindung ,steht. Am unteren Ende des Rohres h ist das Kugelventil n angebracht. Die Zahl der Heizkörper kann beliebig sein. Bei Drehstrom wird man zweckmäßig die Schaltung so vornehmen, wie sie auf der Zeichnung dargestellt ist, d. h. zwei Phasen an einen Heizkörper anschließen. Die Ein- und Ausschaltung der Heizkörper geschieht durch den Regler o, die Dampfentnahme durch den Stutzen p am oberen Ende des Zylinders b. Der Durchmesser des letzteren richtet sich nach der Zahl und der Anordnung der Heizkörper und wird zweckmäßig so gewählt, daß noch eine Wärmeübertragung von den Heizkörpern auf das den Zylinder b umgebende Wasser stattfindet, um dieses vorzuwärmen. Der Zufluß des Wassers erfolgt bei r.The drawing shows a longitudinal section through an electric boiler. The boiler consists of the outer, water-filled boiler a and the inner cylinder b, which receives the radiators c. The radiators are known and of any design and are fastened in the floor d in an easily replaceable manner with the aid of the nuts g. The radiators carry a pipe h in the middle, which is connected to the water space of the boiler a through the lines l and m. The ball valve n is attached to the lower end of the tube h. The number of radiators can be any. With three-phase current it is advisable to make the circuit as shown in the drawing, ie connect two phases to a radiator. The heating element is switched on and off by the controller o, the steam extraction through the nozzle p at the upper end of the cylinder b. The diameter of the latter depends on the number and arrangement of the radiators and is expediently chosen so that there is still heat transfer from the radiators to the water surrounding the cylinder b in order to preheat it. The inflow of water takes place at r.

Nach Inbetriebsetzen des Kessels wird da's Ventil s geöffnet, und es tritt dadurch etwas Wasser unter öffnen der Kugelventile n in die Leituhg h ein. Das Wasser beginnt sofort zu verdampfen, und der Raum über den Heizkörpern wird mit Dampf angefüllt. Dadurch entsteht allmählich auch ein Druck in dem Zylinder b. Das Wasser muß also unter einem gewissen Druck den Heizröhren 1a zugeführt werden.After the boiler has been started up, the valve s is opened, and as a result, some water enters the duct h when the ball valves n are opened. The water immediately begins to evaporate, and the space above the radiators becomes filled with steam. This gradually creates pressure in the cylinder b. The water must therefore be fed to the heating tubes 1a under a certain pressure.
