The system comprises at least one combustion chamber, an expansion turbine, an air compressor driven by the expansion turbine, and means for coupling the expansion turbine to at least one external receiver of mechanical energy. The system further includes means for injecting water to constitute a thermal ballast in the combustion chamber, the quantity of compressed air used remaining close to the quantity of oxidizing air required for stoichiometric combustion. These additional water injection means comprise: a) a mass and heat exchanger for exchanging mass and heat between the combustion products from a condensation recuperator placed on the path of the exhaust gases from the expansion turbine and incoming atmospheric air to enable the air to be pre-moistened prior to entering the compressor; and b) devices for injecting steam and liquid water between the outlet from the air compressor and the inlet to the burner, or into the combustion chamber after the combustion zone and before the first blades of the expansion turbine, the injected steam being produced by a steam recuperator-generator-superheater disposed on the exhaust gases immediately after they leave the expansion turbine, and the liquid water being obtained by recycling the condensed water produced in the condensation recuperator.
