FIELD: metallurgy.
SUBSTANCE: invention provides high-speed gas treatment which makes it possible to increase the rate of iron ore reduction and increase gas treatment efficiency of a single effective cross-section of the boiling layer. By means of parallel lines through which the reducing coke gas passes, the volume of gas passing through each individual boiling layer is reduced. The treatment with successive and parallel movement of the reducing coke gas increases the utilisation factor of the coke gas.
EFFECT: invention enables highly efficient reduction of powdered iron ore in the boiling layer at near atmospheric pressure.
