Delivering up to a 2.5 percent improvement in turbine output—due to recovered aging losses,increased annulus area, and better steam pathflow—this upgrade can reduce outage duration by 21 days when compared to rotor FineLine* Weld Repairs during unplanned outages. This upgrade is available for large fossil steam turbines with a double flow LP and a 43-inch LSB stage bucket that would benefit from an increased annulus area.
- Offers advanced steam path design
- Provides longer latter stage buckets and diaphragms
- Includes advanced brush seals
- Provides integral cover buckets (ICBs)
- Improves inlet/exhaust
- Increases annulus area
