Method and installation for producing cement clinker

A method for producing cement clinker comprising the steps of:

• preheating cement raw meal in a preheater and producing preheated cement raw meal and preheater exhaust gas;
• calcining and sintering the preheated cement raw meal, thus producing exhaust gases which are used in said step of preheating;
• drying replacement fuel to produce dried replacement fuel and drying exhaust gas, wherein the dried replacement fuel is used in said calcining and sintering step;
• quenching the preheater exhaust gases upstream of an SCR catalytic convertor using said drying exhaust gas and/or exhaust vapour condensate thereof, wherein said drying exhaust gas and/or exhaust vapour condensate contain carbon-containing odorous substances and/or ammonia-containing compounds from said replacement fuel;
• and
• cleaning the preheater exhaust gas and the drying exhaust gas and/or exhaust vapor condensate in the SCR catalytic converter, the carbon-containing odorous substances and/or ammonia-containing compounds in the drying exhaust gas and/or exhaust vapour condensate being converted in the SCR catalytic convertor.
