The primary purpose of a stationary gas turbine is to generate power, and diagnostics will only be implemented when it is necessary for reliable power production. However, monitoring of the combustion process and related phenomena in large gas turbines is still limited. Combustion monitoring is being increasingly recognized as a necessary component for safely operating ultra low-NOx gas turbines.

Key features of Combustion Monitoring

  • EZY-CM connects the sensory components and provides TMOS SCADA to process the evaluated data.
  • Combustion Monitoring will collect the raw-measurements, and performs various mathematical operations such as FFT analysis and bandwidth calculation.
  • Real-time feedback of the combustor to adjust the fuel regulation system.
  • It enables the operator to optimize the exhaust emission continuously.
  • And of course all our EZY Basics.

The primary purpose of Combustion Monitoring

  • To raise the alarm, if the acoustics in a specified band is too high.
  • To monitor the relation of data provided by the turbine control and the combustion dynamics.
  • To calculate an auto-tuning mechanism for the installed hardware.
  • To prevent the turbine from substantial damage.

Why is Combustion Monitoring so important

  • Combustion instabilities deteriorate the engine performance and reliability and increase the frequency of required service.
  • Combustion instability can cause flashback, flame blowout due to an increase in the LBO limit mixture ratio, starting problems, damage to combustor hardware, switchover problems, High Cycle Fatigue (HCF) of hot gas path components, and Foreign Object Damage (FOD) to turbine components.
  • In the worst case, a system failure can occur due to extensive structural damage and loss of control.

“EZY Combustion Monitoring offers a unique analytical accuracy level with a joint view and evaluation.”

Typical installation on site

  • The sensor is mounted in a stainless steel block. The whole unit is fixed by using assembly bolt holes from the combuster.
  • The sensor block provides a second adapting connector (NPT 1⁄2”) to support the original tuning pipes.
  • This can be used as reference measurement points during sensor validation.
