The gas turbine system comprises a combustor adapted to combust a fuel and an oxidant and generate pressurized hot combustion gas and a turbine fluidly coupled to the combustor and rotated by expansion of the pressurized hot combustion gas from the combustor. A heat exchanger is fluidly coupled to the turbine and adapted to cool expanded combustion gas exhausted from the turbine. A main oxidant supply line is adapted to supply oxidant to the combustor through the heat exchanger. The oxidant streaming through the heat exchanger is in heat exchange relationship with combustion gas exhausted from the turbine. A fuel supply line supplies fuel to the combustor. A secondary oxidant supply line is adapted to supply oxidant in the fuel supply line upstream of a fuel control valve. Also disclosed is a method of operating the system.
