Description

Verfahren zur Erzielung von Koksersparnissen beim Schachtofenbetrieb. Beim Schrottschmelzen im Martinofen war es bisher bekannt, als Kohlungsmittel oder als Roheisenersatz Koks zu verwensen, der mit einem verschlackbaren, ihn vor dem .Verbrennen schützenden Überzug versehen war. Aucli hat man vorgeschlagen, Brennstofibrikeite, die zum Brennen von Zement oder zum Schmelzen von Eisen dienen sollen, mit einem Überzug zu versehen, der ganz oder teilweise aus Flubmitteln für Zement oder Eisen besteht.Process for achieving coke savings in shaft furnace operation. In the case of scrap smelting in the Martin furnace, it was previously known as a carbon agent or to use as a pig iron substitute coke, which with a slageable, him before the .Burning protective coating was provided. Aucli it has been suggested that fuel manufacturers, which are to be used for burning cement or for melting iron, with a To provide a coating which is wholly or partly made of fluidizing agents for cement or iron consists.

Der Erfinder hat nun erkannt, daß Brennstoffe, wie Koks oder Holzkohle, in der Säule eines Schachtofens durch die aus der Schmelzschicht aufsteigenden Gase, Kohlensäure und Sauerstoff, die: nach den Formeln C+CO_@2COundC+O-CO mit dem Brennstoff in Reaktion treten, nicht oder nur wenig angegriffen werden--, wenn der Brennstoff mit einem verschlackbaren, dünnen, den Zutritt der Gase abhaltenden l;Tberzug versehen ist. Durch die Verhinderung der Kohlenoxydbildung gelangt mehr Brennstoff als bisher z. B. in die Schrrielzschicht eines Kupolofens. Der Aufwand an Brennstoff kann also um diese Menge verringert- werden. Auch wird infolge des Fehlens' von Kohlenoxyd in den Gichtgasen die aus der Gicht des Ofens herausschlagende, äußerst lästige Flamme beseitigt.-The inventor has now recognized that fuels, such as coke or charcoal, in the column of a shaft furnace through the gases rising from the melt layer, Carbonic acid and oxygen, which: according to the formulas C + CO_ @ 2COandC + O-CO with the fuel react, not or only slightly attacked - if the fuel provided with a slageable, thin cover that prevents the entry of gases is. By preventing the formation of carbon oxides, more fuel gets through than before z. B. in the Schrrielzschicht of a cupola furnace. So the amount of fuel used can be be reduced by this amount. Also, as a result of the absence of carbon monoxide in the gout gases the extremely troublesome one leaping out of the gout of the furnace Flame eliminated.
