Ferro Steel - Nitrate Salts
Project example high-temperature corrosion
• Materials testing
• Development and qualification of corrosion-resistant coating concepts
Issue
- In concentrated solar power plants, the heat generated is transferred via a transport and storage medium to a heat exchanger and converted into electrical energy via a turbine
- The transport and storage medium, the so-called solar salt, consisting of sodium and potassium nitrate, increases the efficiency of the plant compared to steam, however, new types of corrosion problems arise
Approach
- Isothermal heat treatments in solar salt (5000 h, 600 °C) to determine the suitability of various materials
- Investigation of corrosion resistance and understanding of corrosion mechanisms
Customer Benefit
- Application-oriented corrosion investigations for material suitability on a wide range of materials
- Material selection based on corrosion resistance and cost considerations
