摘要： For a steam generator comprising a combustion chamber fired with a fossil fuel and/or with particulate fuel containing carbon and at least one burner level comprising several burners (1) and/or at least one level comprising nozzles in the form of upper air nozzles and/or side wall nozzles, each having connected feed means (9, 10, 11, 12) and/or feed lines (2, 4, 5, 9a-9d, 10a-10d, 11a-11d, 12a-12d) through which/by means of which gas flows conveying combustion and/or oxidation oxygen can be fed to burners (1) and/or the nozzles (13) and/or the combustion chamber, a solution should be created by means of which undesired oxygen contents in the flue gas can be avoided during oxyfuel operation of the steam generator in the partial-load range. This is achieved in that the feed means (9, 10, 11, 12) and/or the feed lines (2, 2a-2d, 4, 5, 9a-9d, 10a-10d, 11a-11d, 12a-12d) are designed in such a way that at least one burner (1) or some of the burners (1) independently of the other burners (1) and/or a nozzle (13) or some of the nozzles (13) independently of the other nozzles (13) can be exposed to a gas flow providing the desired oxygen content or the desired oxygen concentration and/or the desired oxygen mass flow.
