Abstract: A system is provided including a current sensor arranged to sense current drawn by an electric motor of a powered device through an AC power line from a power supply and provide current data related to the powered device; a monitoring device arranged to receive the current data from the electrical sensor, the monitoring device including a controller processing the current data to obtain performance data associated with the powered device, the performance data relating to load applied to the electric motor; a data communication device communicating with the monitoring device and arranged to receive the performance data associated with the powered device; and a computing device including a graphical user interface, the computer device receiving a user's selection of the powered device from a list of powered devices and presenting the performance data to the user via the graphical user interface in response to the user's selection.

Abstract: A gas turbine engine includes a combustor system including a lean premix combustor and a water delivery system. The combustor is operable with a fuel/air mixture equivalence ratio less than one and the water delivery system is configured to supply at least one of water or steam to the gas turbine engine such that either the water or the steam is injected into the combustor to control emissions generated by the combustor. As a result, nitrous oxide emissions for specified turbine operating power levels are lowered.

Abstract: A gas turbine engine includes a compressor rotor assembly including a first rotor, a combustor configured to operate with a fuel/air mixture equivalence ratio less than one, and a water injection assembly. The water injection assembly includes a water delivery system including a first plurality of spray nozzles to supply water upstream from the first rotor. The water being supplied to the first rotor is atomized with the first plurality of spray nozzles prior to being supplied to the engine to lower the emissions generated by the combustor.

Abstract: A technique for indirectly determining the temperature of a fluid includes directing at least a portion of the fluid around the outside of a thermally conductive body so as to produce a substantially uniform temperature therein. The fluid temperature is then determined by measuring the resulting temperature within the body. In one embodiment, the fluid is directed around the body by enclosing the body in a shell which has an inlet opening, an outlet opening, and at least one passageway connecting the inlet opening to the outlet opening. In an embodiment which is particularly useful for gas turbine applications, the body is located inside of the outer casing of the turbine and is connected to a guide tube which extends through the outer casing in such a manner that the means employed for measuring the temperature within the body is insertable into and removable from the body through the guide tube.

Abstract: A sensor guide tube for bridging a plenum between a turbine housing and a nozzle assembly includes an offset portion whose offset is substantially equal to half the distance which the nozzle assembly is displaced upstream for clearance restoration. After clearance restoration, the guide tube is rotated 180 degrees to align its lower end with an opening in the nozzle assembly without requiring a sharp bend in the axis of the sensor guide tube.

Abstract: Cooling air from turbine nozzle vanes of a hot gas turbine engine is collected from the vanes by an air connector. A conduit connects to the connector and terminates adjacent a turbine wheel so that air flows through the vanes and through the conduit to be emitted from the end thereof in a jet stream directed against the turbine wheel. A vaned swirl nozzle is inserted in the conduit and adjacent a turbine wheel to impart a turning impetus to the air flow stream being emitted from the nipple. The emitted air stream is then directed tangentially against or adjacent the turbine wheel in the direction of rotation thereof.

Abstract: A flow control body in the aft end of a hollow core of a turbine vane provides localized increased velocity cooling air flow in a wide portion which is otherwise difficult to cool. The flow control body includes lands and grooves with the cooling air being constrained to flow through the grooves and provide localized cooling while conductive heat transfer through the lands to the flow control body provides substantial temperature uniformity along the length of the vane. Turbulence chambers may be formed in the flow control body to further control cooling and the shape or other parameters of the flow control body may be modified to accommodate uneven end-to-end heating of the vane.
