Process for pyrometallurgical processing, in a furnace chamber, of metal-containing waste with steam and/or oxygen-rich gas injected

摘要

In addition to a reducing gas being blown into the furnace, steam and/or an oxygen-rich gas is/are injected parallel to the surface of the smelt. Additionally the total amount of oxygen used in the furnace chamber is lower than the amount required stoichiometrically for complete combustion of organic material in the furnace together with the fuel.
