1 MW
  • Increased gas turbine power output of up to 11 MW in simple cycle duty

  • Higher combined cycle power output.

General Product Information

Increased mass flow for higher output

One of the innovative solutions offered by Siemens Power Service to help you improve the performance of your gas turbine and your competitiveness is the Compressor Mass Flow Increase upgrade.

The Compressor Mass Flow Increase includes the 3D airfoil profile modification of the first four rows of compressor blades and vanes including the inlet guide vane and instrumentation and control adaptations. This upgrade has been designed to increase mass flow for higher power output and exhaust energy from your gas turbine.

Your benefits

The Compressor Mass Flow Increase upgrade can be a cost-effective means to help you improve the overall performance of your gas turbine and combined cycle power plant.

Benefits may include: 

  • Increased gas turbine power output of up to 11 MW in simple cycle duty *
  • Higher combined cycle power output

The modified airfoil profile is state-of-the-art for new Siemens gas turbines of all V-frames manufactured since July 2005.

* Actual results may vary

Scope of Supply

The Compressor Mass Flow Increase upgrade from Siemens is just one of the many innovative modernization packages available.

 

The scope of this upgrade includes for SGT5-4000F: 

  • Replacement of the first five stages of compressor blades and vanes
  • New inlet guide vane position sensor
  • Instrumentation and control modification
  • Optional: Modified blades of the fourth turbine row for optimization of higher mass flow
  • Optional: Replacement of middle hollow shaft by torque disk and additional rotor disk stages 1-4
     

The scope of this upgrade includes for SGT6-4000F: 

  • State-of-the-art CDA-profiles (Controlled Diffusion Airfoils)
  • Replacement of
    - inlet guide vane
    - compressor blades and vanes stages 1-2
  • New inlet guide vane position sensor
