Power plant
First Claim
1. A power plant, comprising:
- a steam system having;
a heat source for heating a water to generate a steam;
a steam turbine driven by the steam generated by said heat source;
a steam condenser for forming a condensed water by condensing an exhaust of said steam turbine; and
condensed water feeding means for feeding the condensed water produced by said steam condenser to said heat source; and
a mixed medium system having;
heat exchanging means for exchanging heat between the exhaust of said steam turbine and a mixed medium;
high pressure separating means for separating the mixed medium heated by said heat exchanging means into liquid and vapor;
a mixed medium turbine driven by the mixed medium of vapor phase separated by said high pressure separating means;
first medium condensing means for forming a condensed liquid by condensing an exhaust of said mixed medium turbine;
first condensed liquid heating means for heating the condensed liquid formed by said first medium condensing means;
intermediate pressure separating means for separating the condensed liquid heated by said first condensed liquid heating means into liquid and vapor;
first condensed liquid feeding means for feeding the condensed liquid formed by said first medium condensing means to said intermediate pressure separating means;
mixing means for mixing the mixed medium of liquid phase separated by said intermediate pressure separating means with the exhaust of said mixed medium turbine on upstream side of said first medium condensing means;
second medium condensing means for forming a condensed liquid by cooling the mixed medium of vapor phase separated by said intermediate pressure separating means;
second condensed liquid feeding means for feeding the condensed liquid formed by said second medium condensing means to said heat exchanging means; and
first separated liquid feeding means for feeding the mixed medium of liquid phase separated by said high pressure separating means to said intermediate pressure separating means.

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).
