Patent ID: 7043917

Claim:
An efficient turbine system that utilizes nuclear thermal energy in a unique combined Carnot cycle and Rankine cycle in a closed cogenerative and regenerative cycle, comprising: a multi-stage gas turbine having multiple turbine stages; a condensible working fluid, heated by a thermal energy source to a superheated gas and delivered in a main path to the internals of the multi-stage gas turbine and in an auxiliary path to each stage of the multi-stage gas turbine as a superheated steam for isothermal expansion, wherein a portion of the condensed working fluid is injected as a liquid into the multi-stage gas turbine before and between the turbine stages for a regenerative cogeneration expansion as a gas that supplements and combines with the primary working fluid in the multi-stage gas turbine; and a multi-stage recovery turbine wherein the combined working fluid is delivered to the multi-stage recovery turbine with a final adiabatic expansion in the multi-stage recovery turbine with work extracted by electric generators connected to at least one of the turbines.
