Abstract
The disclosed power plant can attain an extremely high thermal efficiency, as compared with that of the conventional power plant. The power plant comprises a steam system and a mixed medium system. The steam system comprises a heat source (1) for generating steam; a steam turbine (3) driven by the steam generated by the heat source; a steam condenser (81) for forming condensed water by condensing exhaust of the steam turbine; and a condensed water feeding pump (9) for feeding the water condensed by the steam condenser to the heat source. The mixed medium system comprises a heat exchanger (83) for exchanging heat between the exhaust of the steam turbine and a mixed medium; a separator (85) for separating the mixed medium heated by the heat exchanger (83) into liquid and vapor; a mixed medium turbine (95) driven by the mixed medium of vapor phase separated by the separator (85); a mixer (97) for mixing the exhaust of the mixed medium turbine with the mixed medium of liquid phase separated by the separator (85); a medium condenser (99) for forming condensed liquid by condensing the mixed medium mixed by the mixer; and a liquid feeding pump (102) for feeding the condensed liquid formed by the medium condenser to the heat exchanger (83).
