ASP Upgrade for Fossil LP Rotor IMPROVE TURBINE OUTPUT AND PARTS RELIABILITY


Extend your parts and component reliability, even as your steam turbine experiences different load levels, with GE’s fossil LP rotor replacement and upgrade. Delivering up to a 2.5% improvement in turbine output—due to recovered aging losses, increased annulus area, and better steam path flow—this upgrade can reduce outage duration by 21 days compared to rotor FineLine* weld repairs during unplanned outages. This upgrade is available for large fossil steam turbines with a double-flow LP that would benefit from an increased annulus area.


The LP rotor replacement is applicable to all units that are experiencing reliability issues due to SCC or other similar phenomena. The upgraded LP rotor mentioned above makes reference to a larger annulus. This LP rotor has limited application space if not replacing the LP inner casing. The fossil LP rotor upgrade:


• Offers advanced steam path technology • Provides longer latter stage blades and diaphragms • Includes advanced brush seals • Provides integral cover blades • Increases annulus area • Provides improved reliability to mitigate SCC
