The invention relates to a method for producing hot working gases for a gas turbine system. In a burner, combustion that generates hot combustion waste gas takes place. A portion of the combustion waste gas branches off and feeds into an oxygen separation device. A heat exchanger produces a heated oxygen-containing gas from oxygen-containing gas. The heated oxygen-containing gas feeds to the oxygen separation device. The oxygen separation device includes an oxygen separation means that removes oxygen from the heated oxygen-containing gas and feeds it to the branched-off waste gas. Oxygen-reduced hot gas then leaves the oxygen separation device. Oxygen-enriched branched-off waste gas as well as fuel feed to the burner and form a combustion mixture that bums in the burner while forming the hot combustion waste gases. In order to improve the efficiency of the device, the oxygen-enriched branched-off waste gas heats the oxygen-containing gas.
