Patent ID: 7665304

Claim:
An apparatus for generating power using a heat stream, the apparatus comprising: an evaporator operable to be disposed within the heat stream; a first turbo-generator that includes a turbine coupled with an electrical generator, the first turbo-generator connected to the evaporator to receive refrigerant from the evaporator; a second turbo-generator that includes a turbine coupled with an electrical generator, the second turbo-generator connected to the evaporator in parallel to the first turbo-generator to receive refrigerant from the evaporator; a condenser connected to the first turbo-generator and the second turbo-generator to receive refrigerant therefrom, the condenser having a first shell-side exit port at a first location, a second shell-side exit port at a second location and a plurality of tubes disposed within a housing, the plurality of tubes configured to permit a flow of coolant to enter the condenser, flow through the plurality of tubes and exit the condenser; a first refrigerant feed pump connected to the first shell-side exit port of the condenser to pump refrigerant from the condenser to the evaporator; and a second refrigerant feed pump connected to the second shell-side exit port of the condenser to pump refrigerant from the condenser to the evaporator.
