Ofenanlage, insbesonders zur Eisen-und Stahlerzeugung.
Die Erfindung betrifft eine Ofenanlage, die in erster Linie zur Eisen-und Stahlerzeugung bestimmt ist. Kennzeichnend für diese Anlage ist bei gleichbleibender Flammenrichtung und Abzug der Verbrennungsgase nach unten die Einschaltung eines Schlackenofens zwischen Schmelz-

angewendet worden ; die einseitige Flammenführung ermöglicht es erst, die Schlacke dauernd flüssig zu erhalten, d. h. einen Schlackenofen anzuwenden.
In dem Schlackenofen treffen die von oben kommenden heissen Abgase senkrecht auf das Schlackenbad und streichen dann wagrecht über das Bad hinweg. Die Schlacke wird also gut durchwärmt, so dass sie dünnflüssig bleibt. In diesem Ofen wird die Schlacke entweder mit Zusätzen versehen, um sie als Düngemittel oder zur Erzeugung von Pflastersteinen zu verwenden. Man kann auch die Schlacke aus dem Ofen heraus granulieren. Für letztere Behandlung der Schlacke ist es wichtig, dass der Ofen einen Ausgleicher bildet, d. h. die während des Schmelzvorganges zu verschiedenen Zeiten verschieden stark fliessende Schlacke wird im Ofen gesammelt und kann aus ihm in konstantem Strahle entnommen werden. Vornehmlich beim Roheisenerzprozess ist die Ausgleichswirkung des Ofens von Bedeutung.
Man kann auch im Schlackenofen einzelne Bestandteile bestimmter Schlacken, z. B. Titan, durch Reduktion gewinnen. Hiezu ist allerdings eine besonders hohe Temperatur notwendig, die man mit den Abgasen allein nicht erzielen kann. Deshalb wird der Schlackenofen nach der Erfindung noch mit Brennern versehen, welche die für diesen Fall nötige Temperaturerhöhung erzeugen. Mit Hilfe der Brenner könnte man auch den Schlackenofen bei wechselnder Flammenrichtung anwenden.
Die einseitige Flammenführung ermöglicht es, den Brenner des Schmelzofens so auszubilden, dass entweder der Gasstrom aussen und innen von Luft umgeben ist oder umgekehrt.
Man erhält so eine Flamme mit zwei Verbrennungspunkten, einem inneren und einem äusseren,

Furnace plant, especially for iron and steel production.
The invention relates to a furnace system which is primarily intended for iron and steel production. Characteristic of this system is the switching on of a slag furnace between the smelting furnace, with the flame direction remaining the same and the combustion gases being drawn off downwards.
EMI1.1
been applied; The one-sided flame guidance makes it possible to keep the slag permanently liquid, d. H. to apply a slag furnace.
In the slag furnace, the hot exhaust gases coming from above hit the slag bath vertically and then sweep horizontally across the bath. The slag is therefore well heated so that it remains thin. In this furnace, the slag is either made with additives in order to use it as fertilizer or to make paving stones. You can also granulate the slag from the furnace. For the latter treatment of the slag it is important that the furnace form a leveler, i.e. H. the slag, which flows at different times during the melting process, is collected in the furnace and can be removed from it in a constant stream. The compensating effect of the furnace is particularly important in the pig iron ore process.
You can also in the slag furnace individual components of certain slags, z. B. titanium, win by reduction. For this, however, a particularly high temperature is necessary, which cannot be achieved with the exhaust gases alone. Therefore, the slag furnace according to the invention is also provided with burners which generate the temperature increase required for this case. With the help of the burner one could also use the slag furnace with changing flame direction.
The one-sided flame guidance makes it possible to design the burner of the melting furnace in such a way that either the gas flow outside and inside is surrounded by air or vice versa.
You get a flame with two combustion points, an inner and an outer,
