A power plant and a method for operating a power plant with a CO2 process is shown. The power plant includes a compressor, a turbine, a generator, a recuperator, and a burner unit with an oxygen separation device and a burner. Oxygen-containing gas, CO2 medium from the CO2 process, and fuel are supplied to the burner unit. The oxygen separation device removes oxygen from the oxygen-containing gas and adds it to the CO2 medium. To improve the efficiency of the burner unit, the burner unit is provided with an additional burner. A portion of the oxygen-enriched CO2 medium as well as fuel is fed to the additional burner. Hot CO2 medium formed by the combustion in the additional burner is mixed with the heated CO2 medium at the input of the oxygen separation device.
