Supercharged gas turbine with the steam turbine of a power generator plant of combined cycle

摘要

Supercharged gas turbine with the steam turbine of a power generator plant of combined cycle.In the combined cycle, the gas turbine activates an electric generator and the exhaust gases transfer thermal energy to the liquid of the steam cycle that activates another electric generator or the previous one. At the present time, the only liquid-thermal connection between the gas turbine and the steam generator plant corresponds to the steam generator.The invention introduces two new liquid-thermal connections between both. In the first, the steam turbine activates an air compressor to supercharge the gas turbine. In the second, a heat exchanger transfers the thermal energy of the previously compressed air to the liquid of the cycle of steam coming from the pump.Both connections increase the density of the air in the gas turbine, its specific power and its total energy efficiency.
