A part of the circulating gas is extracted and fed to the afterburner after passing in heat exchange relation with a part of the burnt gas. The heat produced in the burner is fed to the plant either by feeding the burnt gas back to the plant or through heat exchange between the burnt gas and the gas in the plant.
