Rankine cycle device having multiple turbo-generators

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.
