Abstract

The invention relates to a method and a plant for reducing oxidic material, while simultaneously generating a gas suitable for the recovery of thermal energy. A reduction gas (18) is produced containing mainly carbon monoxide and hydrogen from carbonaceous or hydrocarbon-containing material by means of thermal energy from at least one plasma generator (10) in a separate gas- generating shaft (11). The reduction gas thus produced, after optional sulphur separation (22) and after temperature adjustment, is conducted to a reduction shaft (1) containing the oxidic material. The partially spent reduction gas (4) withdrawn from the shaft is freed (5) from water and dust-like particles, after which a part-flow (6) of the return-gas is used for recovering thermal energy, while a part-flow is returned to the process (via 8).
