Description

Kupolofen. Bei Kupolöfen ist es bereits bekannt, außer der gegebenenfalls vorerhitzten Verbrennungsluft Wasserdampf in den Innenraum des Ofens einzuführen.Cupola. In the case of cupolas, it is already known, except where appropriate Preheated combustion air to introduce steam into the interior of the furnace.

Gegenstand der Erfindung ist ein Kupolofen dieser Art, dessen Besonderheit darin besteht, daß der dem Ofen zuzuführende Wasserdampf einem oberhalb des Ofenschachtes angeordneten, durch die Abgase beheizten Dampferzeuger entnommen wird, was gestattet, dem Ofen wieder einen Teil der Wärme zuzuführen, die sonst verloren ginge. Kupolöfen mit einem über dem Ofenschacht angeordneten, durch die Abgase beheizten Dampferzeuger sind zwar schon bekannt. Der durch den Dampferzeuger hervorgebrachte Dampf dient aber nicht zur Erzeugung von Wassergas im Ofeninnern, sondern zum Ansaugen der Luft durch die Luftzuführungsöffnungen nach der Esse hin.The invention relates to a cupola furnace of this type, its special feature consists in the fact that the water vapor to be supplied to the furnace is above the furnace shaft arranged steam generator heated by the exhaust gases is removed, which allows to return some of the heat to the furnace that would otherwise be lost. Cupolas with a steam generator located above the furnace shaft and heated by the exhaust gases are already known. The steam produced by the steam generator is used but not to generate water gas inside the furnace, but to suck in air through the air supply openings towards the forge.

Ein weiteres Merkmal der Erfindung besteht darin, daß der Dampferzeuger und ein zum Überhitzen des in letzterem erzeugten Dampfes dienender überhitzer sowie der durch die Ofenabgase beheizte Winderhitzer zum Vorwärmen der Verbrennungsluft oberhalb der Ofengicht so zusammengruppiert sind, daß der Dampferzeuger über und der Dampfüberhitzer unter dem Wind'hitzer sich befindet, wobei die den überhitzen Dampf führende Leitung in das Innere des die vorgewärmteVerbrennungsluft führenden Rohres verlegt sein kann.Another feature of the invention is that the steam generator and a superheater for superheating the steam generated in the latter, as well as the stove, heated by the furnace exhaust gases, to preheat the combustion air are grouped together above the furnace top so that the steam generator above and the steam superheater is located under the wind heater, with the overheating Line leading to steam into the interior of the preheated combustion air Rohres can be laid.

Auf der Zeichnung ist eine Ausführungsform des Erfindungsgegenstandes beispielsweise dargestellt.The drawing shows an embodiment of the subject matter of the invention for example shown.

Die Gicht z des Kupolofens a ist durch den Luftvorwärmer 3 beliebiger Bauart abgedeckt. Durch ein Rohr ,4 wird diesem Vorwärmer Frischluft zugeführt, die in erhitztem Zustande durch das Rohr 5 in das Innere des Kupolofens geleitet wird. Über dem Vorwärmer ist der beispielsweise aus einem Röhrenbünde- -bestehende Dampferzeuger 6 angeordnet, der mit einem. Überhitzer 7 in Verbindung k@lit, Welcher unterhalb des Vorwärmers 3, also an der Stelle höchster Temperatur, sich befindet. Eine Prallplatte 8 sorgt für einigermaßen gleichmäßige Verteilung der aus dem Schacht aufsteigenden Gase.The top z of the cupola furnace a is more arbitrary due to the air preheater 3 Covered design. Fresh air is supplied to this preheater through a pipe 4, which is passed in the heated state through the tube 5 into the interior of the cupola furnace will. Above the preheater is, for example, made of a tube bundle -Existing steam generator 6 arranged with a. Superheater 7 in connection k @ lit, which is below the preheater 3, i.e. at the point of highest temperature, located. A baffle plate 8 ensures a fairly even distribution the gases rising from the shaft.

Der erzeugte Dampf wird durch eine vom Überhitzer abgezweigte Leitung 9 in das Ofeninnere geleitet, wo er Wassergas erzeugt, hierbei dem Ofen einen Teil der Wärme wieder zuführend, da er ja einem durch die Ofenabgase beheitzen Dampferzeuger entnommen wird.The steam generated is passed through a pipe branched off from the superheater 9 passed into the furnace interior, where it generates water gas, here part of the furnace the heat again, since it is heated by the furnace exhaust gases in a steam generator is removed.

Zur Vermeidung von Wärmeverlusten durch Ausstrahlung ist die den überhitzten Dampf führende Leitung 9 in das Innere des die vorgewärmte Verbrennungsluft führenden Rohres 5 verlegt.To avoid heat loss through radiation, the is overheated Steam leading line 9 into the interior of the preheated combustion air leading Pipe 5 laid.
