Description

Elektrischer Ofen mit Gasabsaugung. Vorliegende 1'_rfindung betrifft eine weitere Ausgestaltung derErfindung nach Patent356424 und besteht darin, daß die durch die Gasab:eitungsrohre gebildetenDampfkessel bzw. auch die an die Absaugungsstutzen anschließenden Gasableitungsrohre lotrecht oder nahezu lotrecht angeordnet sind. Hierdurch wird erreicht, daß der Staub, der in die Ableitungsrohre gelangt, sich darin nicht festsetzen und die Wärmeübertragung nicht behindern kann. Dies macht auch die häufige Reinigung der Rohre entbehrlich. Um die Staubansammlung selbst in den Stutzen zu verhindern und den Staub in den Ofen zurückzuführen, können die Stutzen noch innerhalb des Schachtes lotrecht und die Leitungsrohre und Kessel zu diesen achsial angeordnet sein: Es können aber auch nur die Stutzen vertikal, die Kessel hingegen wagerecht oder geneigt angeordnet sein.Electric oven with gas extraction. The present invention concerns a further embodiment of the invention according to patent 356424 and consists in that the steam boilers formed by the gas discharge pipes or the ones on the suction nozzles subsequent gas discharge pipes are arranged vertically or almost vertically. This ensures that the dust that gets into the discharge pipes, is cannot get stuck in it and cannot hinder the heat transfer. This makes Frequent cleaning of the pipes is also unnecessary. Around the dust accumulation itself to prevent the dust in the nozzle and to return the dust to the furnace, the The nozzle is still perpendicular within the shaft and the pipes and boiler shut this be axially arranged: But it can also only the nozzle vertically, the Boiler, however, can be arranged horizontally or inclined.

Bei vertikaler Anordnung der Kessel ist es von Vorteil, diese mit Beschickungsbehältern zu umgeben, welche auf der dem Ofen zugekehrten Seite offen sind oder Öffnungen besitzen, durch welche die Beschickung in den Schacht abgleitet. Die die Kesselwand umgebende Beschickung bildet dann einen Wärmeisolator für die Kessel, verhütet also eine nutzlose Ausstrahlung der Wärme, wobei sie auch die Bedienungsmannschaft vor lästiger Hitze schützt, die jetzt dem die Kessel umgehenden Beschickungsgut zugute kommt.If the boiler is arranged vertically, it is advantageous to use it with To surround loading containers, which are open on the side facing the oven or have openings through which the feed slides into the shaft. The charge surrounding the boiler wall then forms a heat insulator for the Boiler, thus preventing a useless radiation of heat, whereby it also prevents the operating crew protects against annoying heat that now affects the load bypassing the boiler benefits.

In der Zeichnung sind mehrere Ausführungsformen der Erfindung beispielsweise zur Darstellung gebracht, und zwar zeigt: Abb. i einen Ofen in lotrechtem Längsschnitt, dessen beidseitige Kessel in verschiedener. Weise an den Ofen angeschlossen sind, Abb. 2 den Grundriß dieser Anlage, Abb. 3 in lotrechtem Längsschnitt eine Ofenanlage finit lotrecht angeordneten Kesseln und Stutzen.In the drawing, several embodiments of the invention are for example shown, namely: Fig. i a furnace in vertical longitudinal section, its two-sided boiler in different. Connected to the furnace, Fig. 2 shows the floor plan of this system, Fig. 3 in a vertical longitudinal section of a furnace system finitely vertically arranged vessels and nozzles.

In der Zeichnung bezeichnet i die Ofenwand, 2 den Beschickungsschacht, 3 die Elektroden, 4 die Beschickungsbühnen, 5 die Gasabsaugungsstutzen, 6 die Gasleitungsrohre, 7 die Dampfkessel, 8 die Frischluftdüsen.In the drawing, i denotes the furnace wall, 2 the charging shaft, 3 the electrodes, 4 the loading platforms, 5 the gas suction nozzles, 6 the gas line pipes, 7 the steam boiler, 8 the fresh air nozzles.

Die lotrecht angeordneten Gasabsaugungsstutzen (Abb. 3) sind zweckmäßig so angeordnet und gestaltet, daß sie gleichzeitig die Abgrenzung der Gasfassungsräume bilden.The vertically arranged gas suction nozzles (Fig. 3) are useful arranged and designed in such a way that they also delimit the gas holding spaces form.

Die Gasableitungsrohre können zur Abführung des Staubes entweder unten offene Verlängerungen g (Abb. 'i rechts) oder verschließbare Fangsäcke (Abb. i links) besitzen.The gas discharge pipes can either be below to remove the dust open extensions g (Fig. 'i right) or lockable collecting bags (Fig. i left) own.

Die Dampfkessel können entweder einzeln von Beschickungsbehältern oder Silos umgeben sein, die in den Ofenschacht münden (Abb. Y links), oder es können auch mehrere Kessel von den Behältern umfaßt werden.The steam boilers can either be taken individually from feed tanks or silos that open into the furnace shaft (Fig. Y left), or it can several boilers are also included in the containers.
