అవలోకనం

Indian industrial sector needs both power and thermal energy for their manufacturing processes. For the past few years, Indian industries are showing interest in exploring renewable energies, especially solar energy, due to their economic and environmental-friendly advantages. In this regard, Centre for Solar Energy Materials, ARCI has developed a cost-effective selective absorber coating to convert solar radiation into a heat which can be used for low, medium & high temperature industrial process heat applications. We followed a facile wet chemical route using a combination of novel chemical oxidation, sol-gel and nanoparticle coating methods to develop cost-efficient receiver tubes.

Key Features

  • Suitable for low to medium temperature industrial process heat applications (non-evacuated environment)
  • Solar absorptance: ≤ 94%; Spectral emittance: 0.12
  • Low heat loss property: 0.14 at 250 °C 
  • Thermal stability: ≤ 250 °C 
  • High corrosion resistance ( > 500 hrs withstand in the salt spray test (ASTM B117))
  • High mechanical stability (>5H pencil hardness)            
  • Cost-effective and easily scalable for industrial application
