Power Generation

The harsh environments in the machinery used to generate electric power are particularly challenging for the accurate measurement of critical operating parameters. SCS provides a sensor coating technology which obtains accurate information of operating temperatures in the power turbine.  This temperature knowledge can be used to facilitate predictive maintenance scheduling, reducing unnecessary downtime. Further, the technology can be employed to support the design stage for enhanced plant performance, in particular, for industrial gas turbines.

The range of technologies offered by SCS has applications over the whole spectrum of power generation plants. The robust sensor coatings give the operator reliable temperature measurements in the most challenging environments while paint embodiments suit wider applications where peak temperature knowledge is required such as pipework. The measurement data gives quantitative assessments of component degradation and operating conditions, enabling accurate predictions of remaining service life and adoption of new, more productive, monitoring strategies.

The SCS Thermal History technology has been demonstrated over thousands of hours on a Siemens gas turbine in a UK industrial power plant. It gives the operator the opportunity to record temperature profiles so that critical areas of the plant can be effectively monitored and the plant can be operated to maximum efficiency. Furthermore, unlike thermal imaging technologies, our sensor coatings are immune to emissivity variations so that the temperature information is accurate. They can, therefore, support the development of new machinery designs to achieve the most advanced product.

In addition to electric power plants, the technology can be implemented in the design and operation of solar power plants where operating and storage temperatures are crucial parameters for the running of the plant and its maintenance.

SCS’s Thermal History coatings provide:

  • Accurate temperature profiles for medium and high temperature applications (300C to 900C)
  • Quantitative degradation assessment
  • For extreme thermal and mechanical loads
  • Enhanced test data for novel designs
