1. A gas turbine driven powerplant, comprising:

  • (a) compressor means for producing a downstream flow of air;

    (b) heat exchanger means for cooling said downstream flow of air from said compressor means, said heat exchanger means positioned downstream of said compressor, said heat exchanger means including a fuel carrying coil;

    (c) a regenerator positioned downstream of said heat exchanger means;

    (d) cooling means for carrying a side stream of cooled air from said heat exchanger means to hot section components and/or auxiliary equipment, said cooling means positioned downstream of said heat exchanger means and upstream of said regenerator;

    (e) a combustor positioned downstream of said regenerator, said combustor including a fuel inlet coupled to said fuel carrying coil of said heat exchanger means; and

    (f) a turbine positioned downstream of said combustor.
