System Degradation Monitoring

Every system has a certain degree of degradation, as a result of thermal and mechanical stresses, impurities, system faults, ageing etc. With time, a system or its components reach a point in operation where its maintenance is necessary and economically justified. If no maintenance is provided, a system or a component will be affected in a way that will decrease its efficiency, therefore yielding considerable economic losses in relatively short time. Moreover, a rather fast degradation of a component may result in a component or system faults.

JS energy Team developed a solution that monitors a system and/or component performance in conjunction with technical and economic factors. Based on a system’s critical parameters and economic analysis, a point in performance characteristics is identified, from which the system will no longer operate at its optimal point – hence, higher economic losses can be expected. The system degradation monitoring thus triggers an alarm giving information about maintenance needed and about the type of required maintenance. This enables the operator to act in timely manner, ensuring proper maintenance and, in a long term, ensuring that a system will continuously operate in an optimal way, both with respect to the technical as well as economic perspectives.

Application areas

The system degradation monitoring can be applied on the system and/or a component levels. Common applications are found in the following components:

  • Steam turbines
  • Gas turbines
  • Gas turbine compressors
  • Condensers
  • Regenerative air and water heaters
  • Coal mills
  • Heat exchangers
  • Cooling towers
  • Internal combustion engines
