Title: Method and system for providing cooling for turbine components

Abstract

A system for providing cooling for a turbine component that includes an outer surface exposed to combustion gases is provided. A component base includes at least one fluid supply passage coupleable to a source of cooling fluid. At least one feed passage communicates with the at least one fluid supply passage. At least one delivery channel communicates with the at least one feed passage. At least one cover layer covers the at least one feed passage and the at least one delivery channel, defining at least in part the component outer surface. At least one discharge passage extends to the outer surface. A diffuser section is defined in at least one of the at least one delivery channel and the at least one discharge passage, such that a fluid channeled through the system is diffused prior to discharge adjacent the outer surface.

  • The invention discloses a cooling system for a superconductive exciter winding in a turbogenerator rotor, the exciter winding having winding coils formed of a multiplicity of individual windings that are received in slots formed at the outer periphery of a solid support cylinder and retained therein by a bracing cylinder shrink-fitted on the support cylinder, includes coolant distribution channels disposed radially in teeth located between and defining the slot formed in the support cylinder and in filler members located between winding head coils, the coolant distribution channels surrounding the individual windings over the entire length thereof and being connected inmore » peripheral direction on both sides thereof with coolant channels extending substantially parallel to one another in radial direction with the individual winding coils and surrounding the same at the bottom of the slots; and method of production.« less
  • A cooling system having one or more pin fins with reduced mass for a gas turbine engine is disclosed. The cooling system may include one or more first surfaces defining at least a portion of the cooling system. The pin fin may extend from the surface defining the cooling system and may have a noncircular cross-section taken generally parallel to the surface and at least part of an outer surface of the cross-section forms at least a quartercircle. A downstream side of the pin fin may have a cavity to reduce mass, thereby creating a more efficient turbine airfoil.
  • This patent describes a containment for a boiling water nuclear reactor, a stainless steel containment, the containment having a deposit of a metal of the platinum group of metals on the surfaces thereof exposed to high temperature, high pressure water of the boiling water nuclear reactor.
  • This patent describes a steam turbine monitoring and control system for a steam turbine having a base, a rotor, a cover and an interfacing plant piping system including turbine inlet pipes and exhaust pipes, drain lines, extraction lines, valves such as isolation valves and non-return or check valves and feed water heaters. It comprises a plurality of water detectors located in the interfacing plant piping system, a plurality of heat blankets covering the cover and base of the steam turbine; temperature detector means, coupled to the base and cover of the steam turbine, a detector controller coupled to the pluralitymore » of water detectors; and monitor/alarm means coupled to the detector controller, the plurality of heater blankets, the temperature detector means, the plurality of water detectors.« less
  • An energy control system is described for selectively controlling permissible temperature ranges in a plurality of remote zones from a central control location where the zones each have a heat transfer unit for controlling temperature in the zone. The system is intended for use where the zones are interconnected by pairs of conductors, preferably telephone circuits, with the control location. The system includes a switching arrangement for selectively controlling voltages on the conductors, as by reversing the polarity of normal dc voltage across a conductor pair. Voltage responsive circuits at each zone are interconnected with such conductors. Heat transfer controlmore » switching circuits in each zone are associated with the voltages responsive circuits for altering normal operation of the heat transfer unit in the zone in response to a detected change in voltage on the conductor by the voltage responsive circuit. Operation is altered, as by shutting off the heat transfer unit, in a sense tending to require less energy for heating or cooling the zone thereby conserving energy.« less
