A method for operating a gas turbine engine including a compressor, a combustor, and a turbine, coupled together in serial flow arrangement, and a fuel system including a heat exchanger and an economizer. The method includes channeling fuel through the heat exchanger, channeling a working fluid through the the exchanger to facilitate regulating the operating temperature of the fuel and the operating temperature of the working fluid, and channeling the fuel and the working fluid into the gas turbine engine combustor to facilitate increasing a fuel efficiency of the gas turbine engine. |
