Abstract: A system for cooling a load coupling coupled to a gas turbine and disposed within an exhaust housing is provided. The system includes a shroud configured to be mounted about the load coupling, the shroud defining an inlet passage between the shroud and the load coupling and an outlet passage between the exhaust housing and the shroud. The system also includes a set of blades configured to couple to the load coupling. The set of blades are angled to draw air into the inlet passage as the set of blades rotate with the load coupling.

Abstract: A turbine ventilation system includes a controller that is coupled to an actuator that is coupled to a vane that is disposed across an intake port between a gas turbine enclosure and the turbine ventilation system. The controller can cause the actuator to change a position of the vane to alter an air flow from the turbine ventilation system into the gas turbine enclosure based upon feedback from one or more sensors disposed within the gas turbine enclosure.

Abstract: A gas turbine system includes a plenum that includes an inlet and an outlet. The inlet is configured to receive a flow of oxidant and the outlet is configured to direct the flow of oxidant in a downstream direction. Additionally, a support system is coupled to the plenum and to a cone. The support system enables the cone to move along the support system from a first position to a second position. The cone includes an upstream end and the upstream end is removably coupled to the outlet of the plenum in the first position. When the cone is in the first position, the cone is configured to direct the flow of oxidant in the downstream direction to a gas turbine engine. The upstream end is disposed upstream of the outlet and is decoupled from the outlet when the cone is in the second position.

Abstract: A system includes a modularized air inlet system. The modularized air inlet system includes an air filter house section configured to receive air via an air inlet. The modularized air inlet system also includes a transition/silencer section configured to direct the air from the modularized air inlet system, via an air outlet, into an air inlet plenum coupled to a gas turbine engine enclosure. The modularized air inlet system is configured to couple directly to the air inlet plenum and the gas turbine enclosure without an expansion joint disposed between the modularized air inlet system and the air inlet plenum.

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. These cooling systems are designed to increase the efficiency of ventilating the turbine and rotary shaft, prevent misalignments of the rotary shaft, which may result in thermal stresses, and allow the use of the gas turbine systems in higher ambient temperature environments.

Abstract: A system includes an inlet pipe configured to convey a fluid and a buffer volume configured to buffer the fluid. The buffer volume includes a smallest diameter tube having a smallest diameter, a first inlet end, and a first outlet end. The first inlet end is configured to receive the fluid from the inlet pipe. The buffer volume also includes an intermediate tube surrounding the smallest diameter tube having a first capped end and a second outlet end. The first capped end is positioned next to the outlet end of the smallest diameter tube. The buffer volume also includes a largest diameter tube surrounding the intermediate tube second capped end and a third outlet end. The second capped end is positioned next to the second outlet end of the intermediate tube. The system also includes an outlet pipe configured to convey the fluid from the buffer volume.
