Abstract:
1. A method of using a turbine generator system, comprising: pumping a working fluid in a Rankine cycle from a low pressure reservoir toward at least one compressor interstage cooler; heating the working fluid from heat energy recovered from one or more compression stages of the compressor interstage cooler, at least a portion of the working fluid being pressurized and heated to a gaseous state; directing the heated and pressurized working fluid toward a turbine generator apparatus, the turbine generator apparatus including an inlet conduit to direct the working fluid toward a turbine wheel that is rotatable in response to expansion of the working fluid; and generating electrical energy from the rotation of the turbine wheel, the turbine wheel being coupled to a rotor of an electrical energy generator that rotates within a stator of the electrical energy generator.
