Systems and methods for implementing the systems includes aeroderivative gas turbine subsystem and an energy extraction subsystem extracting energy from an exhaust of the aeroderivative gas turbine subsystem, where the energy extraction subsystem includes a heat exchange subsystem, a dual pressure turbine subsystem, and a condensation-thermal compression subsystem and where an intercooler portion of the heat recovery and vapor generator subsystem permits a working fluid flow rate to be increased to relative to a flow of the exhaust stream resulting in a bottoming cycle gross output increase of at least 23% relative a dual pressure Rankine cycle bottoming cycle, a bottoming cycle net output increase of at least 25% relative a dual pressure Rankine cycle bottoming cycle, a combined cycle net output increase of at least 5.5% relative a dual pressure Rankine cycle bottoming cycle, and a combined cycle efficiency increase to at least 54% relative to 51.1% for a dual pressure Rankine cycle bottoming cycle. |

1. A method for utilizing aeroderivative gas turbine exhaust comprising the steps of:
burning a fuel in an aeroderivative gas turbine subsystem to form an aeroderivative gas turbine exhaust stream, transferring a portion of heat or thermal energy from the aeroderivative gas turbine exhaust stream and an intermediate pressure working fluid stream in a heat recovery and vapor generator subsystem to an increased pressure condensed working fluid stream to form a spent aeroderivative gas turbine exhaust stream and a fully vaporized and superheated increased pressure working fluid stream, converting a portion of heat or thermal energy in the fully vaporized and superheated increased pressure working fluid stream into a first portion of a usable form of energy in a higher pressure turbine unit of a dual pressure turbine subsystem to form the intermediate pressure working fluid stream, forwarding the intermediate pressure working fluid stream into an intercooler portion of the heat recovery and vapor generator subsystem providing additional heat to fully vaporize and superheat the increased pressure condensed working fluid stream to form a cooled intermediate pressure working fluid stream, converting a portion of heat or thermal energy in the cooled intermediate pressure working fluid stream into a second portion of a usable form of energy in a lower pressure turbine unit of the dual pressure turbine subsystem to form a lower pressure spent working fluid stream, transferring heat from the lower pressure spent working fluid stream to a condensed higher pressure working fluid stream in a first heat exchange unit to form a cooled lower pressure spent working fluid stream and a heated condensed higher pressure working fluid stream, condensing the cooled lower pressure spent working fluid stream in a recuperative condenser using a cooling media to form a condensed lower pressure working fluid stream, increasing a pressure of the condensed lower pressure working fluid stream to form the condensed higher pressure working fluid stream, and increasing a pressure of the heated condensed higher pressure working fluid stream to form the increased pressure condensed working fluid stream, where the intercooler portion of the heat recovery and vapor generator subsystem permits a working fluid flow rate to be increased relative to a flow rate of the exhaust stream resulting in a) a bottoming cycle gross output increase of at least 23% relative to a dual pressure Rankine cycle bottoming cycle, b) a bottoming cycle net output increase of at least 25% relative to a dual pressure Rankine cycle bottoming cycle, c) a combined cycle net output increase of at least 5.5% relative to a dual pressure Rankine cycle bottoming cycle, and d) a combined cycle efficiency increase of at least 54% relative to 51.1% for a dual pressure Rankine cycle bottoming cycle. |
