Abstract (en)
[origin: WO2015144651A2] The invention relates to a method for cooling dust-laden exhaust gas from a metallurgical installation. The problem addressed by the invention is that of creating a method and a device for cooling dust-laden hot exhaust gas from a metallurgical installation by means of indirect heat transfer. The problem is solved by means of a method in which the exhaust gas is cooled by a cooling gas by means of indirect heat transfer and the exhaust gas is fed to the cooling process at a temperature above 650°C. The flow direction of the cooling gas is changed at least once. Preferably, the flow direction is reversed. The exhaust gas is cooled in accordance with the counterflow principle.
