Abstract: Support feet of a generator are mounted on foundation columns spaced laterally one from the other, with one column having a block in a recess for receiving the feet on one side of the generator. Guides on a radius and supported by the generator foundation extend through notches on the underside of the block. To locate an end of the generator displaced horizontally from the turbines, the generator is unloaded from the foundation and the block is removed. The generator is then loaded onto the guides and pivoted about a vertical axis to locate at least one end out of alignment with the axis of the turbines enabling removal of the generator rotor in an axial direction.

Abstract: A combined brush/labyrinth tooth seal is provided between a gas shield and the fan tips in the ventilation system of an electrical generator. At least a pair of brush seals straddle a labyrinth tooth providing a close or zero radial clearance with the tips of the fan blades. The brush seals are provided in two double-row bi-directional form. In one embodiment, the brush bristles are slanted toward the fan in a generally axially opposite direction. In a further embodiment, the slanted brush seals engage either the opposite sides of the fan blades or the fan blade tips.

Abstract: In a communications network having at least one server, a plurality of distributed databases communicatively linked to the server, and the distributed databases having installation documents related to power plant equipment stored therein, a plurality of users communicatively linked to the server, a method for providing access to installation documents for assisting at least one user in installing power-plant equipment includes providing at the server an installation software tool for use by the user. The also includes supplying a list correlating source locations of installation documents stored in the plurality of distributed databases with installation software tool destination locations. The installation software tool is populated with links to the installation documents using information from the list, and installation documents are retrieved from the plurality of distributed databases in response to user selection of links using the installation software tool.

Abstract: The method for in situ inspection includes providing a pair of adjacent impingement sleeves forming part of a combustor. A robotic inspection tool carrying an inspection head is inserted through an opening in the outer casing of the gas turbine and manipulated to locate the inspection head between the adjacent impingement sleeves. After inspecting the exterior surface of an impingement sleeve, the inspection tool is withdrawn from the casing. Additionally, a transition piece body forming part of a combustor is inspected by securing a robotic manipulator to an open end of the combustion casing, locating an inspection head on an inspection arm of the manipulator and manipulating the arm to locate the inspection head to inspect interior wall portions of the transition body by displacing the head axially and radially toward wall portions of the transition body.

Abstract: A robotic inspection system for gas turbine combustion components includes an exterior manipulator for visual inspection of the exterior surface of the impingement sleeve, an interior manipulator for visual inspection of the interior of the transition piece body and an annulus manipulator for inspecting the side weld seams of the transition piece body. The exterior manipulator includes an arcuate segment extending about the annular spaced impingement sleeves and a robotic subassembly including a linear rail and an upper arm and forearm mounting an inspection head pivotally coupled to one another for visual inspection of the top, bottom and side external surfaces of the impingement sleeve. The interior manipulator mounts to the open end of the combustion casing and includes an arm mounted for universal pivotal movement to the mount, actuators for pivoting the arm and motors for extending and rotating an inspection head about pan and tilt axes within the interior of the transition piece body.
