Abstract
Apparatus for production of metal sponge or pig iron from metal oxide containing material in piece form using a reduction gas. A reduction reactor shaft (1); reduction gas inlet lines into the interior of the reduction reactor shaft (1); a reduction gas channel body (11) passes through the interior of the reduction reactor shaft (1) for distributing reduction gas; a reduction gas supply line for reduction gas and located below the reduction gas channel body (11) at at least one inner-wall end of the reduction gas channel body (11). The reduction gas channel body (11) has a carrier tube through which a cooling medium can flow. A first portion of the reduction gas is introduced into the bed by reduction gas inlet lines which end in the interior of the reduction reactor shaft. A second portion of the reduction gas is distributed into the bed by the reduction gas channel body. The second portion is supplied essentially vertically below the reduction gas channel body into the interior of the reduction reactor shaft.
