Description
Bei der Ausführung der Erfindung nach dem Hauptpatent 173688 hat sich herausgestellt, daß sich der Sinterungsvorgang zweckmäßig ■ in zwei Stufen zerlegen läßt, von welchen nur die letzte mit einer Wassergasflamme ausgeführt wird. Die Wassergasflamme ist notwendig, um die hohe Hitze zu erzeugen, die zu der Sinterung ohne Zuschläge notwendig ist.When carrying out the invention according to the main patent 173688 it turned out that that the sintering process can expediently ■ be broken down into two stages, only the last of which is carried out with a water gas flame. The water gas flame is necessary to generate the high heat that leads to sintering without additives necessary is.
Zur Erhitzung des Erzes bis in die Nähe der Sinterungstemperatur können jedoch zweckmäßig andere Heizmittel verwendet werden. Hieraus ergibt sich ein Verfahren, bei welchem in einem verhältnismäßig langen Drehofen die Erhitzung des Erzes bis nahe an die Sinterungstemperatur vorgenommen wird, während in einem verhältnismäßig kurzen Ofen und einer verhältnismäßig kleinen Wassergasflamme die Sinterung selbst durchgeführt wird. Im besonderen eignet sich zu der Beheizung der ersten Trommel Generatorgas.However, it is possible to heat the ore up to the vicinity of the sintering temperature other heating means can expediently be used. This results in a procedure in which in a relatively long rotary kiln the ore is heated to near is made to the sintering temperature, while in a relatively short furnace and a relatively small water gas flame the sintering is carried out itself. Particularly suitable generator gas to heat the first drum.
Auf der Zeichnung ist eine Anlage, die zur Ausführung des Verfahrens geeignet ist, dargestellt.The drawing shows a system that is suitable for carrying out the process, shown.
Das zu sinternde Erz gelangt durch den Trichter F in die Vorwärmetrommel D, deren unteres Ende in einem Anbau des Siemensgaserzeugers E ruht. In diesen wird bei a der Unterwind eingeblasen, während durch die Düse b das Generatorgas in geeigneter Richtung in die Trommel D geblasen wird. Bei c tritt Luft in die Kanäle c, c\ c"2, cs des Gaserzeugers ein, wird dort stark vor-The ore to be sintered passes through the funnel F into the preheating drum D, the lower end of which rests in an extension of the Siemens gas generator E. In these, the lower wind while through the die b, the generator gas in a suitable direction in the drum D is blown is blown in a. At c air enters the channels c, c \ c " 2 , c s of the gas generator, is there strongly for-
gewärmt und tritt aus der Öffnung d aus, um sich mit dem Generatorgas zu mischen. Das vorgewärmte Erz fällt aus dem unteren Ende der Vorwärmetrommel in das obere Ende der Wassergastrommel A, welche unterhalb in dem Kopf B gelagert ist und in welcher durch den Brenner C in der durch das Hauptpatent angegebenen Weise eine Wassergasflamme erzeugt wird.warmed and exits the opening d to mix with the generator gas. The preheated ore falls from the lower end of the preheating drum into the upper end of the water gas drum A, which is stored below in the head B and in which a water gas flame is generated by the burner C in the manner indicated by the main patent.
