Erdemir Steel Plant – Turkey

Total Power 150MW

ASME PTC 22

The unit experienced a sudden lost in power output and TGPS assisted in  testing the gas turbine to identify the potential cause of this power output loss. The gas turbine an MS6001B had gone through a major inspection and after the scheduled maintenance the unit was producing less power and the gas turbine heat rate was significant higher.

TGPS tested the gas turbine, gas turbine control system, gas turbine control instrumentation. The activities conducted on-site allowed to identify the cause of the performance loss and create a plan to try to recover this output in the next outage.

Gas turbine upgrade performance test 50 MW– Westinghouse W251B12.

The purpose of the gas turbine performance test was to determine the power output and heat rate improvement after the Gas Turbine Upgrade.

TGPS conducted the evaluation by bringing testing instrumentation, creating a site-specific gas turbine test procedure, conducting the test and creating a gas turbine performance test report.

During the gas turbine evaluation, gas turbine operational data was retrieve from the gas turbine control system as well from the high-precision instrumentation that TGPS installed in a temporary basis.

Gas Turbine parameters has been tested:

  • Gas Turbine Corrected Power Output
  • Gas Turbine Corrected Heat Rate
  • Gas Turbine Efficiency

In addition, during the gas turbine evaluation, the following parameters were calculated. These values will serve as a reference for future performance evaluations of the unit.

  • Firing Temperature
  • Compressor Efficiency
  • Turbine Efficiency
  • Exhaust Temperature
  • Power Output Degradation
  • Heat Rate Degradation

The ASME PTC 22 – Gas Turbine Performance Test Code was followed.
