Recently, the Gansu Provincial Science and Technology Major Special Project "Research and Demonstration of Key Technologies for High-temperature Molten Salt Concentrated Power Generation and Thermal Storage Peak Shaving" (Project No.: 20ZD7GF011), of which Shouhang is the project leader, successfully passed the acceptance.
Among them, the first project, "Key technologies and industrial applications of high-temperature solar absorption coatings for tower molten salt solar thermal power generation", was jointly participated by Dunhuang Shouhang Energy Saving New Energy Co., Ltd., Lanzhou Institute of Chemical Physics of the Chinese Academy of Sciences, and Shouhang Energy Saving Solar Thermal Technology Co., Ltd. This project was recently accepted by experts.
The project was led by Dr. Gao Feng, a technical team of Shouhang and dozens of researchers from the Lanzhou Institute of Chemical Physics of the Chinese Academy of Sciences. They published 6 papers, obtained 5 national invention patents, and trained several outstanding talents including doctoral and master's students.
Dunhuang Shouhang Energy Saving and New Energy Co., Ltd. is mainly responsible for:
1、Heat absorber manufacturing and preparation and process research of tube panel surface absorption coating
2、Responsible for carrying out the 100MW CSP power station coating application demonstration, providing the financial, human, material and other conditions involved in the application demonstration process to ensure the smooth progress of this project
3、Assist the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences to complete all tasks involved in this project
This project has developed a nano high-entropy solar absorption coating with a high absorption rate of 0.975, good spectral selectivity, excellent adhesion, thermal shock resistance and extremely low optical attenuation rate, which can effectively reduce the average cost of electricity and increase the revenue of power stations.
The research team, in collaboration with the Xi'an Thermal Engineering Research Institute, completed the thermal performance evaluation of the absorber coating of a 100-megawatt solar thermal power station for the first time at home and abroad and established a test method. The test results show that the overall performance of the SolarShot1108 high-temperature solar absorption coating is better than that of the Pyromark2500 coating; the overall heat absorption rate of the SolarShot1108 high-temperature solar absorption coating is about 3.9% higher than that of the Pyromark2500.
The project also achieved breakthroughs in key technologies such as preparation of absorption coatings for large absorber tube screens, high-altitude in-situ repair of coatings, solar concentrating solidification, and high-altitude optical performance testing, and can provide technical support for the entire life cycle of materials. The research results of the project were successfully demonstrated and applied in the Shouhang Dunhuang 100MW tower-type solar thermal power station, and met multiple assessment index requirements. SolarShot1108 has become the only product in China that has achieved performance in solar thermal power stations, raising key common technical indicators in the solar thermal field, such as heat absorption rate, to international advanced levels.
