General Product Information

Significant Performance Advantages

The Advanced Compressor Mass Flow Increase Upgrade (CMF++) for the SGT5-4000F fleet is inspired by the proven SGT5-8000H compressor hardware design and was well received in the market.

The upgrade consists of the aerodynamic re-design of the first six stages of the compressor blades and vanes and incorporates the latest Siemens design improvements resulting in a major simple and combined cycle performance increase.  

Your benefits

As a cost-effective means, the Advanced Compressor Mass Flow Increase Upgrade can help you improve the overall performance of your gas turbine and combined cycle power plant and thus helps you remain competitive in the market. The Advanced Compressor Mass Flow Increase Upgrade offers you a clearly technical and monetary quantifiable benefit.

Your technical benefits may include:

  • Increased gas turbine power output of up to 17 MW in simple cycle operation
  • Improved power output of up to 22,5 MW in combined cycle (1x1) operation

The Advanced Compressor Mass Flow Increase Upgrade is a state-of-the-art feature for all new SGT5-4000F machines manufactured since 2011.

* Benefits based on a unit equipped with the Compressor Mass Flow Increase CMF+ and subject to specific technical plant evaluation, expected values with test tolerances @ ISO condition.

Scope of Supply

The Advanced Compressor Mass Flow Increase Upgrade is just one of the many innovative upgrade packages available from Siemens. Each upgrade step undergoes different test methods to optimize reliable engine operation.

The scope of this upgrade includes:

  • Aerodynamic re-design of the compressor stages one to six
  • State-of-the-art controlled diffusion airfoil profiles
  • Adapted flow path of the first compressor disc to the new scoop design
  • Instrumentation and control modification

We recommend the installation of this upgrade at a major outage. Siemens offers a full range of field service capabilities to help you manage your maintenance and outage schedule.

The Advanced Compressor Mass Flow Increase Upgrade with the above mentioned scope of supply is applicable for the SGT5-4000F (V94.3A) / SGT6-4000F(V84.3A) frame and may be combined with other modernizations.
