  • 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.
