Abstract
Process for treatment of gases which are exhausted through a sinter bed in a sintering plant, wherein a distinction can be made between a cold zone of the sintering plant with relatively low gas temperatures and a hot zone of the sintering plant with substantially higher gas temperatures. The gases from the cold zone of the sintering plant and the gases from the hot zone of the sintering plant are exhausted and treated as separate partial flows.
