Abstract
An apparatus for generating thermal and electrical energy includes an internal combustion engine connected to and adapted to drive a generator for providing electrical power and a brake for generating thermal energy. In one embodiment, a heat carrier flows through appropriate conduits for absorbing heat energy from the brake, from the combustion chamber of the engine, and from the engine exhaust gases and delivers the heat energy to a end-use heat exchanger, for example, a room or space heater. In a second embodiment, the engine exhaust gas flow is used to drive a gas turbine that, in turn, drives a compressor in a thermal cycle to provide additional heat transfer capability.
Claims9
An apparatus for generating thermal energy and electrical energy, said apparatus comprising:
- an internal combustion engine having a power take-off shaft means, said internal combustion engine having at least one combustion chamber and means for conducting a cooling fluid in heat exchange relationship with said combustion chamber for receiving thermal energy therefrom, the thermal energy provided from said combustion chamber constituting a first source of thermal energy;
- generator means for generating electrical energy connected to said power take-off shaft means;
- a brake means connected to said power take-off shaft means for generating thermal energy in response to power applied thereto from said internal combustion engine, means for conducting a cooling fluid in heat exchange relationship with said brake means for receiving thermal energy therefrom, the thermal energy provided from said brake means constituting a second source of thermal energy;
- an exhaust gas line leading from said combustion chamber of said internal combustion engine and means for conducting a cooling fluid in heat exchange relationship with the exhaust gases for receiving thermal energy therefrom, the thermal energy provided from the exhaust gases constituting a third source of thermal energy;
- and
- conduit means for connecting said sources of thermal energy in a closed circuit with an end-use heat exchanger, said brake means connected into said closed circuit across a shunt line portion of said closed circuit.
