DEVICE FOR THE CLOSED-LOOP CONTROL OF PROCESS GASES IN A PLANT FOR PRODUCING DIRECTLY REDUCED METALS ORES |
摘要 |
A device for closed-loop control of process gases (11) in a plant (8) for producing directly reduced metal ores includes at least one reduction unit (10), an appliance upstream of the reduction unit (10) for separating gas mixtures (18), a gas purification appliance (13) connected downstream of the reduction unit (10) for rate control of process gases (11). Process gases (11) are obtained by recycling from the production process itself and from a plant for pig iron generation (1) via a supply conduit (16). An open-loop pressure control appliance (15) upstream of a junction of the supply conduit (16) into a return conduit (14) for the process gases (11) such that a pressure level for the appliance for separating gas mixtures (18) is kept constant and the process gases (9,11) are controlled in a closed-loop manner in a plant for producing directly reduced metal ores (8). |
