FIELD: metallurgy, namely iron production. SUBSTANCE: system for producing iron by means of direct reduction of iron is combined with turbine power generator and, preferably with cryogenic unit for air separation in which exhaust gas of direct reduction process drives turbine. Oxygen from unit for air separation is used for producing synthesis gas for direct reduction. Nitrogen from unit for air separation lowers creation of NOx and increases power production in turbine. EFFECT: possibility for effectively using system in any geographical zone independently upon presence of outer electric energy sources in such zone. 8 cl, 5 dwg _
