Definitions

  • the disclosure relates generally to installation apparatuses for turbine systems, and more particularly, to installation apparatuses for load-couplings of turbine systems, and methods of installing load-couplings within turbine systems using installation apparatuses.
  • frames or diffusers are typically attached or coupled to an outlet of a turbine component. These diffusers are attached to the turbine component to safely direct gases passing through and/or from the turbine component into the environment surrounding the turbine system, or alternatively, to direct the gases to another component that may utilize the gases for additional processes (e.g., a heat recovery steam generator).
  • the diffusers are positioned directly adjacent to, and downstream from generators of the turbine system.
  • the clearance between the diffusers and generators of the turbine system may be minimal (e.g., 2-3 meters) to improve efficiency of the turbine system and/or to reduce the risk of undesirable exposure and/or undesirable operation of a load-coupling section of the rotor that may couple a turbine section of the rotor with the generator section of the rotor.
  • one conventional process of replacing the load-coupling includes removing/disassembling the diffuser and/or generator of the turbine system to provide access to the load-coupling.
  • This conventional process is labor intensive, requires the removal/disassembling of large components (e.g., diffuser formed as single, unitary component) and/or a large number of components, and requires the turbine system to be non-operational for an extend period of time.
  • a crane is used to both remove, support, and install the load-couplings with the turbine system.
  • the crane is positioned above the diffuser and generator and the load-coupling is rotated to be substantially vertical and then lowered into the space or clearance between the diffuser and the generator.
  • the load-coupling may then be rotated to be substantially horizontal and simultaneously positioned or inserted into the diffuser on the side adjacent the generator to be coupled to the turbine section of the rotor with the generator section of the rotor, respectively.
  • this conventional process is also time consuming, and increases the risk of the load-coupling, the diffuser, and/or the generator from being damaged if the load-coupling is not perfectly passed or threaded through the minimal clearance between the diffuser and the generator.
  • this conventional process for installing the load-coupling may only work when the load-coupling includes a length that is smaller than a predetermined length. That is, in some instances the load-coupling for the turbine system may be too long to install using the crane because there may not be enough space or clearance between the diffuser and the generator to allow the load-coupling to rotate to be substantially horizontal before being coupled to the turbine section and generator section of the rotor.
  • Patent Application EP 0 051 178 A1 discloses methods and apparatus for assembling and disassembling the impeller rotor and blades of a rotary machine.
  • the apparatus comprising a support frame for supporting an end of the impeller rotor, said support frame being movable on rails located on a base plate adjacent the rotary machine.
  • a first aspect of the disclosure provides an installation apparatus for a load-coupling of a turbine system, as set forth in claim 1.
  • a second aspect of the disclosure provides a method of installing a load-coupling in a turbine system using an installation apparatus, as defined in claim 9.
  • downstream and upstream are terms that indicate a direction relative to the flow of a fluid, such as the working fluid through the turbine engine or, for example, the flow of air through the combustor or coolant through one of the turbine's component systems.
  • the term “downstream” corresponds to the direction of flow of the fluid, and the term “upstream” refers to the direction opposite to the flow.
  • forward and “aft,” without any further specificity, refer to directions, with “forward” referring to the front or compressor end of the engine, and “aft” referring to the rearward or turbine end of the engine. Additionally, the terms “leading” and “trailing” may be used and/or understood as being similar in description as the terms “forward” and “aft,” respectively. It is often required to describe parts that are at differing radial, axial and/or circumferential positions.
  • the “A” axis represents an axial orientation.
  • the terms “axial” and/or “axially” refer to the relative position/direction of objects along axis A, which is substantially parallel with the axis of rotation of the turbine system (in particular, the rotor).
  • radial and/or radially refer to the relative position/direction of objects along an axis "R” (see, FIG. 1 ), which is substantially perpendicular with axis A and intersects axis A at only one location.
  • circumferential refers to movement or position around axis A (e.g., axis "C").
  • the following disclosure relates generally to installation apparatuses for turbine systems, and more particularly, to installation apparatuses for load-couplings of turbine systems, and methods of installing load-couplings within turbine systems using installation apparatuses.
