Routine and preventative maintenance activities
Concentrator plants require ongoing maintenance to sustain reflectivity, tracking accuracy, and thermal system integrity. A structured maintenance program minimizes downtime and ensures design performance over the plant lifetime.
Typical maintenance tasks:
- Mirror cleaning and inspection: remove dust and check for coating degradation.
- Drive and bearing servicing: lubricate and replace drive components to maintain tracking accuracy.
- Receiver checks: inspect seals, tubes, and absorber coatings for corrosion or fatigue.
- Fluid handling: monitor and replace heat transfer fluids and check pumps and valves.
Additional activities:
- Structural inspections after storms or high winds.
- Calibration of sensors, encoders, and control systems.
- Preventive replacement of high-wear parts and alignment corrections.
A mix of scheduled, condition-based, and predictive maintenance reduces unexpected failures and extends system life while controlling operating costs.
