Combustion Dynamics Monitoring System (CDMS)

In recent years, environmental regulations have forced power generation plants to lower NOx emissions by burning a leaner flame in the combustor. As a result, many sites have experienced combustor pulsations that amplify as they move through the turbine. This pressure amplification produces significant vibration that can damage the turbine package.

In order to avoid or minimize the amount of damage to the turbine and peripheral components, it is essential to quickly detect the presence of these combustor pulsations and to alter the combustion process such as changing fuel splits.

AS-250 SpectralMon™ and AS-330R CombustionGuard™ protect your turbine from damage caused by combustion dynamics or pulsations.
