  • SYSTEMS RELATING TO GEOTHERMAL ENERGY AND THE OPERATION OF GAS TURBINE ENGINES
    Publication number: 20110132571
    Abstract: A geothermal heat exchange system for use in a gas turbine power plant that includes an inlet plenum that directs a flow of air to a compressor that compresses a flow of air that is then mixed with a fuel and combusted in a combustor such that the resulting flow of hot gas is directed through a turbine, the geothermal heat exchange system comprising means for exchanging heat between a ground and the flow of air moving through the inlet plenum.

  • Mixer for cooling and sealing air system for turbomachinery
    Patent number: 7698898
    Abstract: A system for mixing flows from a compressor is provided. The system comprises an ejector that combines a first flow and a second flow, from the compressor, into a third flow. A bypass flow is connected between the first flow and the third flow. A mixer combines the bypass flow and the third flow into a fourth flow. The fourth flow has a pressure and temperature intermediate the respective pressures and temperatures of the bypass flow and the third flow.

  • Variable motive nozzle ejector for use with turbine engines
    Patent number: 7536864
    Abstract: A gas turbine engine system. The system includes a compressor with a first compressor stage and a second compressor stage, a turbine with a first turbine stage and a second turbine stage, a first flow path connecting the first compressor stage and the first turbine stage, a second flow path connecting the second compressor stage and the second turbine stage, a crossover flow path connecting the first flow path and the second flow path, and an ejector positioned about the crossover flow path and the first flow path. The ejector may be a variable motive nozzle ejector.
