Recently, the installation work of two high- and low-temperature molten salt storage tanks for the **Energy Group’s Dunhuang ‘Thermal Energy +’ 100MW molten salt linear Fresnel solar thermal project**, which was constructed by Lansi Heavy Equipment, was successfully completed. The system is now ready for preheating, and all performance parameters meet the design requirements precisely; as a result, **Energy Longyuan Power Longyuan (Dunhuang) New Energy Development Co., Ltd. sent a letter of praise. This project is a **large-scale wind and solar power base project that utilizes the \"linear Fresnel concentration + molten salt heat storage\" technology. Among them, the core supporting facility is the heat storage island system, which consists of two high and low temperature molten salt storage tanks. These tanks are made of 347H stainless steel and high-temperature resistant carbon steel respectively, with a diameter of 33.8 meters and a height of 15 meters. The design and manufacturing requirements for these tanks are high, and their construction is challenging. Lanshi Heavy Equipment formed a technical task force, developed specialized construction plans, defined 128 quality control points, and organized the work meticulously with scientific methods to advance the project construction in a high-quality and efficient manner. During this period, facing various challenges such as the special operating conditions of the molten salt storage tanks, stringent quality standards, precise inspection requirements, and a tight schedule, the project team remained focused on its goals and overcame these difficulties. Through three-shift operations, enhanced implementation of the three-stage inspection process, safety briefings, and practical drills, the construction progress, project quality, and safety standards were all improved simultaneously. Not only were all construction tasks completed to high standards, but an accident-free record was also achieved, laying a solid foundation for the safe and stable operation of the project’s production facilities. This performance earned high recognition and praise from the client.
