Description

Verfahren zum Betrieb von Flammöfen unter Anreicherung der Verbrennungsluft mit Sauerstoff. Die Anreicherung von Verbrennungsluft . mit Sauerstoff ist bekannt. .Desgleichen ein Verfahren, die Frischwirkung durch Zufuhr von Sauerstoff zu steigern.Process for operating flame furnaces with enrichment of the combustion air with oxygen. The enrichment of combustion air. with oxygen is known. Also a process to increase the freshness effect by adding oxygen.

Gemäß vorliegender Erfindung werden die beiden angeführten Wirkungen bei dein Betrieb eines Flammofens vereinigt. 1'K ach der Erfindung wird so verfahren, daß die Regelung der Stärke der chemischen Einwirkung des Sauerstoffes auf das Metallbad durch Veränderung des Zeitpunktes der Mischung von Gas und Luft bzw. Sauerstoff erfolgt. Hierdurch findet eine Erhöhung der Temperatur und gleichzeitig eine Beeinflussung der I metallurgischen Vorgänge statt. Werden z. B. Gas und Luft unvermischt in den Ofen gebracht, so entsteht durch den freien Sauerstoff eine starke Frischwirkung, selbst wenn im übrigen ohne Luftüberschuß gearbeitet wird. Erfolgt aber eine vollständige Verinischung schon vor dem Eintritt in den Ofen, so verbindet sich der gesamte Sauerstoff der Verbrennungsluft mit den verbrennbaren Bestandteilen des Heizgases, bevor er mit dem Bad in Berührung kommen kann, und die Frischwirkung wird infolgedessen geringer. Diese Wirkung hängt wesentlich von dem "Leitpunkt der Vermischung von Gas und Luft ab, so daß hierdurch ein Rlittel gegeben ist, um die chemische Einwirkung des Sauerstoffes auf. das Metallbad in einfacher Weise zu regeln.According to the present invention, the above two effects are achieved united in your operation of a flame furnace. According to the invention, the procedure is that the regulation of the strength of the chemical action of oxygen on the metal bath by changing the point in time at which gas and air or oxygen are mixed he follows. This increases the temperature and has an influence at the same time the metallurgical processes take place. Are z. B. Gas and air unmixed in the Brought to the oven, the free oxygen creates a strong freshness effect, even if the rest of the work is carried out without excess air. But if there is a complete Mixing before entering the furnace, so all the oxygen is combined the combustion air with the combustible components of the heating gas before it can come into contact with the bath, and the freshness effect is reduced as a result. This effect depends essentially on the "control point of the mixing of gas and air so that this gives a third to the chemical action of the oxygen on. to regulate the metal bath in a simple manner.
