Abstract
An improved power system that recovers heat energy from the exhaust of internal combustion utilizing an internal combustion engine in combination with a Brayton bottoming system. Heat from a thermal battery drives the bottoming system to create electrical power that supplements the engine power. Sources of heat for the thermal battery include hot engine exhaust gasses, electrically generated heat, and residual heat from motor/generators.
Claims15
An energy efficient combined cycle power system, comprising:
- an internal combustion engine driving a first motor/generator;
- a heat exchanger;
- means connecting the engine and heat exchanger for providing heat generated by the engine to the heat exchanger;
- a first expander driving a second motor/generator;
- means connecting the heat exchanger and the first expander for providing heat from the heat exchanger to the first expander;
- a third motor/generator;
- and
- means for providing power between at least one of the first and second motor/generators to the third motor/generator.
