The present invention relates to a method and an apparatus for the production and the melting of liquid pig iron or of liquid steel intermediate products in a melt-down gasifier, with the introduction of oxygen-containing gas through oxygen nozzles into the solid bed. According to the invention, in the case of at least one oxygen nozzle, at least two gas streams are introduced. As a result, the risk of the fluidization of the solid bed is reduced, and the number of raceways is increased.
La présente invention concerne un procédé et un dispositif de fabrication et de fusion de fonte brute liquide ou de demi-produits d'acier liquide dans un gazéificateur de fusion avec introduction d'un gaz contenant de l'oxygène dans le lit fixe par le biais de buses à oxygène. Selon l'invention, au moins deux flux de gaz sont introduits pour au moins une buse à oxygène. On réduit ainsi le risque de fluidisation du lit fixe et on augmente le nombre de chemins.
