  • Patent number: 9897003
    Abstract: A method of operating a turbine assembly is provided. The method includes receiving a flow of air at a filter house that includes a first heat exchanger. The temperature of the air is controlled with the first heat exchanger by one of selectively cooling the air and by selectively heating the air. The air is then channeled from the first heat exchanger to a second heat exchanger to facilitate cooling the air.

  • Patent number: 9446342
    Abstract: The cylindrical or conical shaped particle separator operates based on cyclone-induced flow sweeping the face of the cylindrical separator screen, creating inertial separation of suspended particles. The separator screen comprises of multitude of parallel, evenly spaced, asymmetrically profiled, linear, screen elements arranged in a cylindrical or conical grid-like shape parallel with the axis of the cylinder or cone. The cyclone effect is created by the rotational, helical path of the fluid inside or outside of the cylindrical or conical separator screen. The spinning, rotating fluid sweeps the inner or outer side of the stationary or rotating screen, passing approximately perpendicularly over the linear grid-like elements and gaps between the elements. The screen elements may be wires, bars, narrow strips, airfoil vanes or other similar linear elements with a flow separation edge on the trailing end of the profile of the element.

  • Patent number: 8468830
    Abstract: A heating and cooling system for inlet air of a turbine compressor. The heating and cooling system may include a fluid coil positioned about the turbine compressor and a thermal energy storage tank. The fluid coil and the thermal energy storage tank are in fluid communication such that fluid is both provided to the fluid coil from the thermal energy storage tank for exchanging heat with the inlet air and returned to the thermal energy storage tank without further heat exchange.

  • Patent number: 8266910
    Abstract: An application and process that incorporates an external heat source to increase the temperature of the airstream entering a compressor section of a combustion turbine. The application and process may perform an anti-icing operation that may not require an Inlet Bleed Heat system (IBH) to operate. Additionally, the application and process may perform an anti-icing operation that may allow for the IGV angle to remain nearly constant. The application and process may increase the output and efficiency of a combustion turbine operating at partload by delaying IBH operation and delaying the closing IGVs.
