1. A plant for the generation of mechanical energy by using a fluid, the plant comprising:

  • (a) a gas turbine;

    (b) a plurality of compressor units;

    (c) a plurality of compressor turbines for driving the compressor units, the compressor turbines being connected in series with the compressor units;

    (d) a combustion chamber connected with the gas turbine, the expanded air from the compressor turbines being directed into the combustion chamber;

    (e) a main heat exchanger being disposed between the compressor turbines and the compressor units, the exhaust from the gas turbine being directed through the main heat exchanger;

    (f) an interim heat exchanger being disposed between the compressor units;

    (g) a first external heat exchanger being disposed downstream of the main heat exchanger; and

    (h) a second external heat exchanger being disposed between the last compressor turbine and the combustion chamber of the gas turbine;

    wherein the first and the second external heat exchangers enable a predetermined h/p ratio to be achieved between the thermal power given off in the interim and the external heat exchangers and the mechanical power delivered to the gas turbine.
