(57) The invention relates to a method for reducing pollutants in exhaust gases during thermal material treatment, in particular for clinker production, in which the exhaust gases have a temperature greater than or equal to 150°C when entering the dust removal device. The invention also relates to corresponding systems and to the use of the calorific energy content of the furnace exhaust gas guided through a mill bypass for heating other exhaust gas flows, in particular the exhaust gas exiting from a raw mill.
