Keep Aging Gas Turbines Competitive with Coatings and Material Upgrades – Combined Cycle Journal

Keep Aging Gas Turbines Competitive with Coatings and Material Upgrades

By modifying and improving gas-turbine components with coatings and upgraded materials, owner/operators can cost-effectively maintain the value of their legacy frame machines—and in some cases increase the value of those assets.

Presented by Garret Haegelin, HICoat Division Superintendent, Sulzer Turbo Services Houston.

Presentation Takeaways

This presentation will use a case-study approach to outline the options available to you and how they can be combined to improve reliability and parts life. Case studies will illustrate how coatings and material upgrades can achieve the following:

  • Minimal cost upgrades to maximize repair value.
  • Repairs to avoid major asset replacement.
  • Improved operating efficiency.
  • Longer run cycles.
  • Slower degradation of parts, translating to:
    o Reduced repair costs.
    o Reduced repair lead times.
    o Shorter outages.
  • Increased component life.
