Abstract:
A turbine shroud block removal apparatus. In one embodiment, the apparatus includes a first base plate including a first armature. The first base plate may be releasably coupled to a first shroud block. The apparatus also may also include a second base plate including a second armature. The second base plate may be releasably coupled to a second shroud block positioned adjacent the first shroud block. Additionally, the apparatus may include an actuator coupled to the first armature of the first base plate and the second armature of the second base plate. The actuator may change a distance between the first shroud block and the second shroud block.
Abstract:
A remote turbine component replacement apparatus for a turbine assembly includes an arm having a first end and a second end, the first end configured to be positioned at a user accessible region and the second end configured to extend to a remote location of the turbine assembly, the remote location in close proximity with a turbine material zone to be removed. Also included is a base portion proximate the second end, the base portion configured to engage a turbine component located at the remote location. Further included is a material removal tool disposed proximate the base portion. Yet further included is a debris removal component disposed proximate the base portion.
Abstract:
An apparatus and method for a more time efficient measurement of backlash in one or more variable guide vanes of a gas turbine system are provided. A mounting structure, with an indicator attached thereto, may be provided. Further, a guide structure may be provided to allow the mounting structure to be moved adjacent to two or more variable guide vanes without moving the guide structure.
Abstract:
A turbomachine rotor blade milling machine system includes a fixture having a body including first and second opposing surfaces and a slot. The fixture is configured and disposed to connect with first and second rotor blade sections mounted in a rotor wheel. A mounting system includes at least one mounting element coupled to one of the first and second opposing surfaces of the body at the slot. A milling machine is coupled to the one of the first and second opposing surfaces through the at least one mounting element. The milling machine includes a cutter and is configured and disposed to form an opening extending axially through a dovetail portion of a third rotor blade section arranged between the first and second rotor blade sections.
Abstract:
An inlet guide vane removal assembly includes a support frame with a support plate. At least one force device is coupled to the support plate. A puller bracket is attached to the at least one force device. The puller bracket has an open-ended slot defined therethrough, and a plurality of flanges positioned to engage an installed inlet guide vane. When the force device is actuated, the puller bracket is displaced relative to the support frame to facilitate removing the inlet guide vane.
Abstract:
Various embodiments include apparatuses for performing maintenance on a gas turbine (GT) nozzle, along with related methods. One apparatus can include: a nozzle engagement sled for releasably engaging the nozzle, the nozzle engagement sled including: a sled body; a locking member coupled with the sled body, the locking member sized to complement a slot in the nozzle; a sled slot within a side of the sled body, the sled slot for engaging a rail within the GT; and at least one wheel for transporting the sled body within the GT.

Abstract:
Various embodiments include approaches for installing a flow sleeve relative to a gas turbine transition piece. Some embodiments include an apparatus for coupling a gas turbine transition piece with a flow sleeve, the installation apparatus having: a radially inner ring; a plurality of expander segments extending radially outward from the radially inner ring, the plurality of expander segments each having an axially ramped segment sized to gradually expand the flow sleeve to couple with the gas turbine transition piece as the flow sleeve is moved along the plurality of expander segments; and a circumferentially disposed space separating each pair of adjacent expander segments in the plurality of expander segments.
Abstract:
An apparatus for cleaning an inner surface of a slot includes a first block segment that has an outer perimeter that conforms to and fits inside the inner surface of the slot. A first cleaning pad is connected to the first block segment and extends beyond at least a portion of the outer perimeter of the first block segment.
Abstract:
Combustor maintenance assemblies, tools and methods for manipulating cross-fire tubes in combustor assemblies are provided. A tool includes a base and an arm pivotally connected to the base. The arm includes an effort portion and a load portion, the load portion extendable into a passage defined by the compressor discharge casing. The tool further includes a contact member extending from the load portion to contact the cross-fire tube. The contact member includes a head end for contacting a second end of the cross-fire tube, and a joint disposed between the head end and the load portion, the joint allowing movement of the head end relative to the load portion. The arm is movable such that the contact member contacts the cross-fire tube and applies a force to the cross-fire tube generally along a longitudinal axis of the cross-fire tube.
