General Product Information

3D design to power up the performance

One of the innovative solutions offered by Siemens to help you improve your operating plant competitiveness and profitability are the Siemens innovative 3-dimensional blades and vanes for the turbine stages.

Siemens innovative 3-dimensional blades and vanes are characterized by an aerodynamic blade and vane design with optimal efficiency as well as ability for retrofitting during service life. This generation of turbine stages blades and vanes has a new, optimized aerodynamic airfoil designed with enhanced material, coatings, an improved cooling air path and a reduction of parasitic losses.

 

The Siemens innovative 3-dimensional blades and vanes provide significant performance advantages and offers attractive financial payback options.

Siemens innovative 3-dimensional blades and vanes are state-of-the-art for new Siemens gas turbines of the SGT5-2000E (V94.2) and SGT6-2000E (V84.2).

 

* Actual results may vary.

Scope of Supply

Siemens innovative 3-dimensional blades and vanes for the turbine stages modernization include the following new designed profiles and additional turbine parts:

 

Turbine stages 1 and 2:

  • Turbine vane 1 (including riffle seals)
  • Turbine blade 1
  • Turbine vane 2 (including riffle seals and U-shaped seal ring segments)
  • Turbine blade 2
  • Cooling air throttle for vane 2
  • Control optimization of corrected turbine outlet temperature

The upgrade includes execution of the following field work:

  • Machining of the turbine vane carrier in vane 2 section inserting the cooling air throttle.

Turbine stages 3 and 4:

  • Turbine vane 3 (including riffle seals and U-shaped seal ring segments)
  • Turbine blade 3 (including new damper)
  • Turbine vane 4 (including riffle seals)
  • Turbine blade 4

 

Siemens innovative 3-dimensional blades and vanes can potentially be implemented in a row-by-row replacement. A major outage for the installation of this modernization is estimated. We offer a full range of field service capabilities to help you manage your maintenance and outage schedules.
