Abstract
An energy supply system includes a gas turbine which drives an air compressor. Heat generated by adiabatic compression of air in the air compressor is recovered by a heat exchanger. The air from which the heat has been recovered is used to operate an air turbine. The air turbine drives a generator. Adiabatic expansion of the air in the air turbine produces air at low temperature. Thermal energy at low temperature of the air is recovered by another heat exchanger. The waste heat from the gas turbine is recovered by a boiler system of a heat recovery type.
