FIELD: metallurgy.
SUBSTANCE: invention relates to a device for controlling process gases in an apparatus for producing metal by direct reduction of ore. Device has reducing reactor, a device mounted upstream of reducing reactor for separation of gas mixtures with coupled pressure device, a gas-cleaning device arranged downstream of reducing reactor configured to adjust amount of process gases, and a device for pressure control, which is arranged ahead of connection of supply pipeline to bypass pipeline for process gases, particularly so-called exhaust gas pressure level is maintained constant in device for separation of gas mixtures with coupled discharge device.
EFFECT: invention ensures reduction of capital costs and operating costs, in particular to electric power.
