Abstract (en)

[origin: EP1158258A2] Recovering the waste gas energy of a metallurgical process from a melting vessel comprises branching a partial amount of the energy contained in the process gas from the waste gas line; and feeding to the metallurgical process mixed with fresh air or transferred to fresh air to reduce the energy requirement. An Independent claim is also included for a device for recovering the waste gas energy of a metallurgical process from a melting vessel comprising an annular line (5) arranged around the casing (2) of the vessel so that a gas and/or fresh air line (6) is connected to the annular line. Injection openings (7) are arranged over the periphery of the casing and open out in the inside of the vessel through the lining of the vessel.
