Super-polished high-pressure compressor blades
If you’re struggling to maintain compressor performance over time as a result of blade fouling, GE’s super-polished high-pressure compressor blades are configured to markedly reduce fouling rates and boost uptime.
Benefits
Lowered gas turbine engine downtime
Compressor blade and vane fouling is generally due to harsh environmental conditions and inadequate gas turbine air filtration. Our super-polished high-pressure compressor blades let operators extend their offline water-wash intervals and lower engine downtime—resulting in far less fouling to key gas turbine compressor components.
Preserved compressor blade performance
This product introduces new Stage 2 – 14 high-pressure compressor (HPC) blades, Stage 1 – 13 HPC vanes, an outlet guide vane (OGV), and an inlet guide vane (IGV) to improve HPC performance and extend water wash intervals.
Additionally, the Stage 6 – 14 blades have a re-configured tip to help reduce the severity of identified problems if tip rub between the blades and compressor case occurs.
High-resistance mirror finish
All high-pressure compressor blades and vanes are replaced with ones polished to a mirror-like finish. The durable finish resists dirt and debris accumulation, extending gas turbine compressor performance between water wash intervals.
Benefits:
- Extending gas turbine compressor water-wash intervals
- Lower performance degradation between water washes
- Improvements in power output and heat rate
