Happy New Year 2024 **********************【A Decade of Great Development in Chemical Engineering Equipment】Continuous updates and summaries are available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Engineering Forum) ***************** On November 30th, Xi’an Huijin Technology Co., Ltd., a subsidiary of MCC SEDI, held a ceremony to mark the completion of production of its 10kV/10MW high-voltage, high-power molten salt energy storage electric heating device. This device utilizes an internationally innovative technology for efficient induction heating of fluids by connecting directly to the high-voltage power grid, representing a significant breakthrough in the field of fluid electric heating. It will be used in the 100,000-kilowatt solar thermal energy storage project as part of the Yumen “solar thermal energy storage + photovoltaic + wind power” demonstration project. This is the first time such a device has been applied in the field of energy storage, and it will bring about major advancements in molten salt-based energy storage solutions, transforming the landscape of long-term energy storage. It will also accelerate the industrial application of molten salt energy storage in areas such as industrial steam generation during off-peak electricity times and for energy storage in new energy systems. The MCC SDI 10kV/10MW high-voltage, high-power molten salt energy storage electric heating device overcomes the technical limitations of low-voltage and resistive heating in the domestic and international molten salt electric heating industry. It utilizes high-voltage electricity up to 35kV to heat the molten salt with high power, speed, and precision. Its advantages include direct connection to high-voltage power grids, low line losses, high individual power output, long equipment lifespan, uniform heat transfer, high insulation performance, and high heat transfer efficiency. It is therefore a more efficient (overall efficiency ≥97%), energy-saving, stable, and reliable high-voltage heater. On December 1, Xi’an Huijin Technology held a launch event for the 10kV/10MW high-voltage, high-power molten salt energy storage electric heating device. Yu Weijiang, the chairman of Xi’an Huijin Technology, along with representatives from companies involved in energy storage such as China Power Construction and China Energy Engineering Group, as well as officials from the China Industrial Energy Conservation and Clean Production Association, were present to witness the device’s departure from the factory, the announcement of the testing results, the signing ceremony, and to engage in related technical discussions. At the meeting, Director Zhang Yongwu of the **Electric Furnace Quality Supervision and Inspection Center presented the test results for the 10kV/10MW molten salt electric heating energy storage system. It was confirmed that various parameters such as the insulation voltage rating, maximum power output, adjustment range, and power factor all met or exceeded the **standard requirements, indicating that the system has stable performance and excellent quality. At the press conference, Wuchan Zhongda (Zhejiang) Energy Storage Technology Co., Ltd., Hunan China Nuclear Thermal Salt Technology Co., Ltd., Yantai Henghui Energy Saving Group Co., Ltd., and Yantai Jisen Metallurgical Equipment Co., Ltd. each held signing ceremonies for cooperation agreements with Xi’an Huijin Technology Co., Ltd. on stage. The conference invited experts from relevant fields to conduct technical exchanges and share their insights. Dr. Yang Bin from Xi’an Huijin Technology Co., Ltd. discussed the application of electric heating technology in the petrochemical industry, while Dr. Wang Guiquan from Yantai Henghui Energy Saving Group Co., Ltd. talked about the use of efficient heat exchange technologies and equipment in the energy storage sector. Yan Ze, the chairman of Hunan China Nuclear Thermal Salt Technology Co., Ltd., shared his thoughts on the safety management of molten salts. The experts possess extensive experience and in-depth research in their respective fields; they have unique insights into the technical challenges they encounter, and they have contributed to the advancement of technology in their areas of study. The exchanges that took place were highly fruitful. Next, the MECED Molten Salt Electric Heating Equipment Project Team will adopt a highly responsible attitude toward the client, work together as a cohesive unit, organize everything carefully, and deliver the project successfully through enthusiastic and meticulous service.
