Abstract

A DC furnace for generation of reduction gas for use in connection with direct reduction of metallic oxides and materials containing such oxides, comprising: a reactor provided with carbonaceous electrodes connected to the poles of a DC source, an arc being formed between said two electrodes; and means for supplying a gas containing carbon dioxide into said arc whereby carbon monoxide is formed according to C + CO2?2 CO. A single outlet for the formed gas is arranged in the form of a hollow channel in one of said electrodes. And a process for the generation of such reduction gas.
