Abstract

Brenner, insbesondere Hochgeschwindigkeitsbrenner, für einen Schachtofen, insbesondere einen Kupolofen, mit einer zentralen Austrittsöffnung und konzentrisch um die zentrale Austrittsöffnung angeordnete, im wesentlichen ringförmige Austrittsöffnungsbereiche.Burners, in particular high-speed burners, for a shaft furnace, in particular a cupola furnace, with a central outlet opening and concentric around the Central outlet opening arranged, substantially annular outlet opening areas.

Erfindungsgemäß sind wenigstens drei ringförmige Austrittsöffnungsbereiche vorgesehen. Die zentrale Austrittsöffnung und/oder wenigstens einer der ringförmigen Austrittsöffnungsbereiche sind vorzugsweise absperrbar ausgebildet.According to the invention there are at least three annular outlet opening areas intended. The central outlet opening and / or at least one of the annular ones Exit opening areas are preferably designed to be shut off.

Der Brenner ermöglicht eine Vielzahl von Verfahrensvarianten hinsichtlich der Zuführung von Sauerstoff und Brenngas in einen Schachtofen.The burner enables a large number of process variants with regard to the feed of oxygen and fuel gas in a shaft furnace.

Schachtofen, insbesondere Kupolofen, sowie Verfahren zum Betreiben eines Schachtofens zur Erzeugung von Metallen, insbesondere von Gußeisen, und Metalllegierungen, mit einem Ofenschacht, der mit einem entsprechenden Einsatz befüllt ist bzw. andauernd oder periodisch befüllt und aus dem bodenseitig die Gußeisensehmelze entnommen wird, sowie mit einer Zuführeinrichtung, über die der Ofenschacht, insbesondere in seinem unteren Bereich, mit Sauerstoff oder einem Sauerstoff-haltigen Gasgemisch versorgt wird.Shaft furnace, in particular cupola furnace, and method for operating a Shaft furnace for the production of metals, in particular cast iron, and Metal alloys, with a furnace shaft, with a corresponding insert is filled or filled continuously or periodically and the cast iron melt from the bottom is removed, as well as with a feed device via which the Furnace shaft, especially in its lower area, with oxygen or a Oxygen-containing gas mixture is supplied.

Erfindungsgemäß ist die Zuführvorrichtungen als wenigstens ein erfindungsgemäßer Brenner und/oder als wenigstens eine Sauerstofflanze mit wenigstens einem aufgesetzten Brenner ausgebildet.According to the invention, the feed devices are at least one according to the invention Burner and / or as at least one oxygen lance with at least one attached burner trained.
