Description

Verfahren zur Nutzbarmachung von Gichtstaub, Kiesabbränden oder anderen eisenhaltigen Stoffen. ach dem Verfahren des Hauptpatents 4i8ioi kann (las in den in der Kohlenstaubflamine zum Schmelzen gebrachten eisenhaltigen Stoffen enthaltene Eisen durch Hinzufügen von festem Kohlenstoff iln L;berschuß unmitt-2lbar zu metallischem Eisen reduziert «-erden. Da diese Reduktion ein endothermischer Vorgang ist, so ist es zur Durchführung eines ununterbrochenen Verfahrens erforderlich, die durch die Reduktion gebundene Wärme durch Hinzufügung fühlbarer Wärme zu ersetzen.Process for the utilization of gout dust, gravel burns or other ferrous substances. After the procedure of the main patent 4i8ioi (read in the ferrous substances contained in the coal dust flames melted Iron by adding solid carbon in the oil; excess immediately to metallic Iron reduced «earth. Since this reduction is an endothermic process, so it is required to carry out an uninterrupted process carried out by replace the reduction in bound heat by adding sensible heat.

Dies kann wie inl Hauptpatent durch Ersatz der fühlbaren Wärme aus der Strahlungswärme der Kohlenstaubflamme geschehen. Gemäß der Erfindung @@-;xd dieser Wärmezusatz dadurch erzeugt, daß in den unteren Teil des Verbrennungsraumes eine aus Koks, Kohle o. dgl. bestehende Schicht von festem Kohlenstoff eingebracht und kalte oder vor-(rhitzte Luft eingeblasen wird. Hierdurch wird ein Teil des Kohlenstoffes verbrannt und die frei werdende Wärme hält die Kohlenstoffschicht (lauernd auf der für die Durchführung des Reduktionsvorganges erforderlichen Reduktionstemperatur. Hierbei wird die Höhe der Kohlenstoffschicht so reichlich bemessen, daß den niederrieselnden, flüssigen, eisenhaltigen Stoffen genügend Zeit zur ollständigen Reduktion gegeben wird.As in the main patent, this can be done by replacing the sensible heat the radiant heat of the pulverized coal flame. According to the invention @@ -; xd this addition of heat is generated in that in the lower part of the combustion chamber a layer of solid carbon made of coke, coal or the like is introduced and cold or preheated air is blown in. This releases some of the carbon burned and the heat released holds the carbon layer (lurking on the reduction temperature required for carrying out the reduction process. Here, the height of the carbon layer is dimensioned so generously that the trickling down, liquid, ferrous substances given enough time for complete reduction will.
