In a turbine power plant having a closed loop steam turbine system and a closed loop exhaust turbine system;
- a closed loop steam turbine system which comprises the combination of:
- a steam turbine having a fluid inlet and fluid outlet mounted on a shaft;
- a generator means operatively connected to said shaft;
- a condenser having a fluid inlet and a fluid outlet and a cooling means between its inlet and outlet;
- a pump having a fluid inlet and fluid outlet and a pressurizing and circulating means between its inlet and outlet, said pump mounted on a shaft of the exhaust turbine system;
- a heater having a fluid inlet and fluid outlet which uses an external fuel source to superheat fluid flowing between its inlet and outlet;
- a fluid conduit means operatively connecting the following in a closed loop cycle, the outlet of said heater to the inlet of said steam turbine, the outlet of said steam turbine to the inlet of said condenser, the outlet of said condenser to the inlet of said pump, the outlet of said pump to the inlet of said heater;
- said fluid conduit means operatively connecting the outlet of said steam turbine to the inlet of said condenser is designed to provide exhaust heat energy to said exhaust turbine system as the working fluid flows from said steam turbine to said condenser;
- said fluid conduit means operatively connecting the outlet of said pump to the inlet of said heater is designed to receive heat energy from said exhaust turbine system and from the hot exhaust of said steam turbine as the working fluid flows from said pump to said heater;
- a closed loop exhaust turbine system which comprises the combination of:
- a first, second, and third turbines each having a fluid inlet and outlet and each mounted on a common shaft;
