  • Patent number: 11578621
    Abstract: One or more cooling systems for ventilating a turbine and rotary shaft of a gas turbine system is provided. The gas turbine system includes a gas turbine engine and a turbine exhaust collector in separate enclosures. A first cooling system includes an educator that sucks exhaust gas through a diffuser and directs it out of the turbine exhaust collector enclosure based on suction pressure created from the high velocity of exhaust gas. A second cooling system include struts that enable the exhaust gas to flow from the diffusers to a ventilation flow stack. A third cooling system includes exhaust gas sucked from an opening to a top duct based on suction pressure created from the rotation of the rotary shaft disposed about a coupling. A guideway associated with the third cooling system also directs the exhaust gas to flow to the top duct.

  • Patent number: 11473495
    Abstract: A system includes a clutchless synchronous condensing coupling configured to couple a turbine shaft of a gas turbine system to a generator shaft of a synchronous generator of a power generation system. The clutchless synchronous condensing coupling includes a first coupling portion configured to couple to the turbine shaft, and a second coupling portion configured to couple to the generator shaft. The clutchless synchronous condensing coupling is configured to allow the power generation system to operate in an active power mode and a reactive power mode without a clutch assembly.

  • Publication number: 20180347398
    Abstract: A system includes a gas turbine engine, including a compressor, a combustor, and a turbine. The system includes an intercooler configured to receive a discharge air from the compressor and to cool the discharge air. The system includes a first conduit to divert a portion of the cooled discharge air from the intercooler or a location downstream of the intercooler to a bearing located within the turbine to pressurize the bearing to block leakage of fluid from the bearing.

  • Patent number: 9909499
    Abstract: Embodiments of the present disclosure are directed toward a system and method to drain a fuel manifold wherein a fuel drainage and purge system includes a fuel manifold and a drainage line extending from the fuel manifold. The drainage line is configured to flow a liquid-gas mixture from the fuel manifold. The fuel drainage and purge system also includes a drain valve disposed along the drainage line, a vent line extending from the drainage line upstream of the drain valve, a vent valve disposed along the vent line, and a drainage trap arranged along the drainage line downstream of the drain valve. The drainage trap is configured to separate the liquid-gas mixture into a liquid stream and a gaseous stream.

  • Patent number: 6334746
    Abstract: A trailer mounts a turbine and a generator for transport to a power generation site. The mount for the turbine includes a sub-base mounted for pivotal movement adjacent a rear end thereof proximate the forward end of the generator. The forward end of the sub-base is secured to the trailer by an isolator mount. The two mounts constitute a 3-point mounting system for the sub-base and turbine carried thereby whereby during transport, the sub-base and turbine are enabled for limited angular deflection of the turbine axis relative to the generator rotor axis. The pivotal mounting adjacent the interconnection between the turbine and generator rotors lies along discrete opposite sides of the trailer. Torque is transmitted from the turbine to the generator base through the pivotal mountings. At the power generation site, the sub-base is locked down and minimal adjustment is required to align the turbine and generator rotors.
