System for the generation of mechanical and/or electrical energy

摘要

A system for the generation of energy includes a further chain of units coupled with a gas turbine plant and at least one compressor consuming mechanical energy and/or at least one generator generating electrical energy. The further chain of units comprises a closed circuit having a work fluid and at least one heat exchanger, at least one expander for expanding the work fluid and for subsequently obtaining mechanical energy for the compressor and/or generator, at least one condenser for condensing the expanded work medium, and at least one pump for conveying the work fluid. The coupling of the gas turbine plant to the further chain of units is carried out by means of the heat exchanger which is fed with heat by means of the compressor air of the compressor and starts the closed circuit through the work fluid.
