Concentrated Solar Power
High-temperature insulation for concentrated solar power — receivers, molten-salt tanks and piping, and fire-safety systems using ceramic fiber and calcium silicate.
Concentrated solar power runs at very high temperatures — molten salt around 565°C and receivers far higher — so insulation must survive sustained heat and resist salt corrosion. Receiver towers can exceed 200 m, making lightweight, durable high-temp materials essential for both efficiency and safety.
Material Comparison
| Material | Best fit | Service temp | Key advantage |
|---|---|---|---|
| Ceramic fiber | Receivers, salt tanks, piping | 800-1200°C | High-temp, corrosion resistant |
| Calcium silicate | Equipment, fire-safety systems | 600-1000°C | Structural, integrated fire+insulation |
Application Scenarios
Concentrated Solar Power Application Scenarios
- CSP receivers — ceramic fiber insulates tower and trough receivers operating under intense concentrated flux (tower receivers can stand over 200 m high).
- Molten-salt tank insulation — ceramic fiber resists salt corrosion while limiting standby heat loss.
- High-temperature molten-salt piping — ceramic fiber on salt lines withstands heat and corrosion.
- Equipment insulation — calcium silicate on various plant equipment.
- Fire-safety systems — calcium silicate in integrated fire-and-insulation packages for the plant.
