Abstract:
In a method for reducing the NOx emissions of a rotary kiln of a clinker production plant, fuel supplied through a burner of the rotary kiln is burned along with primary air fed through the burner, wherein the primary air has a lower oxygen content and the primary air has an oxygen content reduced relative to that of the ambient air and a temperature increased relative to that of the ambient air, and the primary air is obtained by mixing ambient air with exhaust gas from the rotary kiln or from a heat exchanger connected to the rotary kiln and used for preheating raw meal. The primary air is further obtained by mixing with hot air, in particular waste air from a clinker cooler.

Claim (Index 9):
A device for carrying out the method according to  claim 1 , comprising a rotary kiln with a burner, a heat exchanger connected to the rotary kiln on the exhaust-gas side, and a clinker cooler, wherein a primary gas supply for the burner with a main fan is provided, wherein a mixing device including an ambient air supply, an exhaust gas supply fed with the exhaust gas from the heat exchanger, and a hot air supply fed with the waste air from the clinker cooler are disposed upstream of the main fan.
