摘要： A method and system for controlling fuel in a gas turbine engine including a fuel supply system channeling fuel to a combustor are provided. The system includes a first heat exchanger configured to transfer heat between a working fluid and a first cooling medium. The system also includes a second heat exchanger in series flow communication with the first heat exchanger wherein the second heat exchanger is configured to transfer heat between the working fluid and a second cooling medium. The system further includes a modulating valve configured to control the flow of at least one of the first and the second cooling media to maintain a temperature of the first or second cooling medium substantially equal to a predetermined limit.
