Abstract: Embodiments provide a method and apparatus to lower the temperature and heat content of the ambient air at the inlet to a gas combustion turbine to enhance power generation. Embodiments can use multiple, staged direct contact air chillers, variable flow secondary water chilling systems, constant flow primary water chilling systems with water chilling units arranged for parallel chilled water flow, and a coolant water circulation system used for heat rejection with open cooling towers. Alternatives can use a chilled water thermal storage system, and/or waste heat to drive at least part of the water chilling process. With the included apparatus a method to allow adiabatic air chilling is available for operation during periods of lower ambient air conditions when needs for power augmentation may not be as great.

Abstract: A gas turbine engine includes a fan located at a forward portion of the gas turbine engine, a compressor section and a turbine section arranged in serial flow order. The compressor section and the turbine section together define a core airflow path. A rotary member is rotatable with at least a portion of the compressor section and with at least a portion of the turbine section. An outlet guide vane assembly includes multiple outlet guide vanes located in an exhaust airflow path downstream of the turbine section. The multiple outlet guide vanes being spaced-apart circumferentially from each other over an angular range of about 360 degrees, and each multiple outlet guide vane defining a radial extent. At least one of the multiple outlet guide vanes includes a cold fluid passageway extending at least partially radially therethrough through which a fluid coolant flows and another of the multiple guide vanes includes a heated fluid passageway extending at least partially radially therethrough through which the fluid coolant flows and receives heat from exhaust airflow from the core airflow path.

Abstract: A system includes an air manifold, a fuel manifold, and a plurality of fuel injectors. At least one of the fuel injectors includes a heat exchanger portion for supplying compressed, cooled air form the heat exchanger portion to the air manifold. An air valve is operatively connected to an outlet of the air manifold for controlling release of air from the air manifold. A controller is operatively connected to the air valve, wherein the controller includes machine readable instructions configured to control the air valve to regulate flow of air through the air valve based on fuel temperatures in the fuel channel. The machine readable instructions can be configured to cause the controller to flow air through the air valve in a heat exchange mode if a fuel temperature in the fuel injectors is below a predetermined fuel temperature.
