Beschreibung
Zusammenfassung:	A method for burning material, such as carbonate rocks, in a parallel-flow regenerative shaft kiln having two shafts which are operated alternately as a burning shaft and as a regenerative shaft and are connected to one another by means of a connecting channel, wherein the material flows through a material inlet into a preheating zone for preheating the material, a burning zone for burning the material and a cooling zone for cooling the material to a material outlet, wherein a cooling gas is admitted into the cooling zone, wherein exhaust gas is discharged from one of the shafts via an exhaust gas outlet, wherein the exhaust gas discharged from the shaft via the exhaust gas outlet is at least partially introduced into at least one of the shafts.
