Abstract

An apparatus and a method for reducing harmful substances, particularly nitrogen oxides, in combustion exhaust gases in a combustion process performed with an oxygen-nitrogen-air mixture (atmosphere). At least one conduit (chamber 48) that conducts the oxygen-nitrogen-air mixture is provided and associated with an exhaust gas conduit (34) that is connected to a combustion chamber, with the conduit being provided with an intermediate wall (44) that separator the chamber is permeable to the oxygen or stores it. Of the oxygen-nitrogen-air mixture, only the oxygen is supplied to a combustion waste gas that is conducted to a combustion chamber.
