<p>The invention relates to a method for operating a furnace (1) in a system for processing metal, in particular a strand casting system, wherein exhaust gas (A) from the furnace (1) is conducted along a flow path (S) through at least one recuperator (2), wherein fresh air (F) for the furnace (1) is preheated in the recuperator (2) by means of the thermal energy contained in the exhaust gas (A) and the heated air is supplied to the furnace (1) and wherein the exhaust gas (A) is conducted into a flue (3) downstream of the recuperator (2) in the flow direction. In order to achieve improved use of energy, a heat exchanger (4), to which water (W) is supplied and in which the water is heated, is arranged in the flow path (S) or parallel to the flow path (S), wherein the heated water or the generated steam is used to operate a system for generating electricity (5) or is fed to a consumer of hot water. The invention further relates to a system for processing metal, in particular a strand casting system.</p> |
