Abstract

PURPOSE: To take out a significant difference between temperature of a low boiling point medium and an exhaust of a gas turbine as an effective power by combining the gas turbine, a steam turbine, and a low boiling point medium turbine in a cascade connection, thereby enabling a highly efficient operation.
CONSTITUTION: A gas turbine 1, a steam turbine 4, and a low boiling point medium turbine 7 are respectively connected to generators 25-1W3 and combined in the form of a cascade. The air to be sucked by a compressor 2 of the gas turbine 1 is cooled by an air cooling LNG carbureter 9 to reduce the power required by the compressor 2 and atomize the LNG19. A steam 15 is generated in a boiler 3 by using a hot exhaust gas of the gas turbine 1 to heat a low boiling point medium liquid 18 in an evaporator 5. Steam 17 is further heated, due to medium temperature exhaust gas 12' of the gas turbine, into a hot low boiling point medium steam 24. The low boiling point medium steam being used in the turbine 7 is condensed by a low temperature of the LNG19 into a carbureter 8.
