Assessment of solid wastes and by-products as solid particle materials for concentrated solar power plants


Publication Highlights

  1. CSP Advancements: Utilizing steel by-products and natural materials as solid particles in Concentrated Solar Plants (CSP) offers cost savings and sustainable progress by reducing reliance on synthetic materials.
  2. Materials Selection: Electric arc furnace dust, black slag, and gossan ore possess favorable properties for CSP applications, including composition and solar absorption.
  3. Thermal Ageing Study: The research involves subjecting these materials to thermal ageing at 900°C for varying durations (0 h, 300 h, and 500 h) to replicate CSP conditions.
  4. Property Evaluation: Physico-chemical, morphological, thermal, and optical properties are assessed to determine stability and suitability for CSP use.
  5. Optimal Candidate: Electric arc furnace black slag emerges as the most suitable choice for CSP due to its superior absorptance, thermal conductivity, and chemical stability following thermal ageing.
