Beschreibung
Zusammenfassung:	The present invention relates to a shaft furnace (10) for burning material, in particular material containing carbonate, said furnace comprising a shaft (12) which has, in the direction of flow of the material: a material inlet (22); at least one burning zone (26) for burning the material having at least one fuel line (14, 16) for admitting fuel into the burning zone (26); a cooling zone (28) having a cooling air inlet (36) for cooling the burned material; and a material outlet (30) for discharging the material from the shaft furnace (10); wherein the shaft furnace (10) has an exhaust gas discharge line (24) for discharging exhaust gas from the shaft (12), and wherein the shaft furnace (10) has a cooling gas discharge device (38) for discharging cooling air from the shaft (12), said device extending from the cooling zone (28) into the burning zone (26) and from the burning zone (26) out of the shaft (12), wherein the cooling gas discharge device (38) is connected to a control element (40) for controlling the amount of gas flowing through the cooling gas discharge device (38).
