Abstract
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 streams through oxygen nozzles into the solid bed. At least one oxygen nozzle has a single gas supply and introduces at least two gas streams. Using plural gas streams from a nozzle reduces the risk of fluidization of the solid bed because the number of gas raceways in materials in the gasifier is increased.
