At the Binchang Power Plant in Shaanxi, this globally leading clean coal power technology has received authoritative approval, marking a significant breakthrough for China in the field of efficient and clean power generation. On November 28, the world’s first 660-megawatt high-efficiency ultra-supercritical circulating fluidized bed power generation project celebrated its first anniversary of safe operation and passed an authoritative appraisal. All the performance indicators of this project have reached or exceeded the design values; it not only fills a gap in the global industry but also signifies an important breakthrough by our country in the field of clean power generation technology. This major scientific and technological project, guided by the **Energy Administration and led by Harbin Electric Group Boiler Company**, with the participation of over 10 organizations including Shaanxi Binchang Wenjiapo Power Generation Co., Ltd. of Shaanxi Coal Group and Tsinghua University, has successfully resulted in the creation of the world’s first ultra-high-parameter power plant with excellent performance characteristics. 01 Technical breakthroughs: Advanced clean power generation technologies. For thermal power plants, the boiler functions as the \"heart\" – it burns fuel to produce high-pressure, high-temperature steam that drives the turbine to generate electricity; its performance directly determines the efficiency of power production and the level of environmental protection. “\"Ultra-supercritical\" is like the \"ultimate version of a pressure cooker\": at normal atmospheric pressure, water boils at 100°C, but this type of boiler can raise the pressure of water to over 29 megapascals and heat it to above 600°C; at these conditions, the boundary between water and steam becomes blurred, resulting in a significantly higher efficiency in converting heat into electricity. The “circulating fluidized bed” represents a clever approach to “tumbling combustion”: the fuel is crushed to the size of pumpkin seeds, and air currents cause it to tumble, heat up, and burn inside the furnace, just like roasted chestnuts. This method ensures more complete combustion, and it is also possible to add desulfurizing agents at any time to reduce pollution. Since it began generating electricity on November 27, 2024, this project has undergone a full year of operational testing, during which the boiler efficiency reached 93.68%, enabling long-term, continuous, safe, and stable operation. 02 The Path to Localization: A Leap from Catching Up to Leading. As one of the first domestic companies to propose and develop supercritical circulating fluidized bed boilers, Harbin Electric Group Boiler Company conducted in-depth research on the key technical issues related to such boilers during the 10th Five-Year Plan period. Through technical efforts during the 13th Five-Year Plan period and continued research and development during the 14th Five-Year Plan period, China has not only developed the world’s first 660-megawatt high-efficiency ultra-supercritical circulating fluidized bed boiler that can operate stably and efficiently, but also established a theoretical, design, manufacturing, and operation technology framework with entirely independent intellectual property rights. This technology is 100% domestically developed; the main unit, all associated auxiliary equipment, and the control system are all independently designed and manufactured by Chinese companies, and its technical parameters have surpassed those of foreign-made products in every aspect. 03 Multiple Benefits: Dual advantages for energy and the environment. This innovative unit is capable of turning waste into treasure each year, by cleanly converting approximately 2 million tons of coal with low calorific value and low-quality fuels such as slurry and gangue. These “waste materials” that used to occupy land in mining areas and were prone to spontaneous combustion have been reused as resources through this unit. At the same time, this unit also acts as a “stabilizer” for the new power system. It can operate stably within a range from 25% low load to 100% full load, with the temperatures of the main steam and reheat steam always maintained at high levels. This feature makes the unit a \"stabilizer\" for the local power grid in absorbing new energy sources such as wind power, hydroelectric power, and photovoltaic power, thus laying a solid foundation for achieving a green and low-carbon energy transition. 04 Authoritative Certification: Consensus Evaluation by Academicians and Experts. At the site of the Binchang Power Plant project in Shaanxi, an appraisal meeting organized by the China National Machinery Industry Federation brought together numerous authoritative experts, including Academicians Wang Shuangming, Gao Xiang, and Yang Yongping from the Chinese Academy of Engineering. Experts conducted a comprehensive evaluation of this project and concluded that the technology of this world’s first 660-megawatt high-efficiency ultra-supercritical circulating fluidized bed boiler represents an \"internationally leading level\". **A responsible official from the Department of Energy Conservation and Scientific and Technological Equipment of the Energy Bureau attended the meeting to provide guidance, while relevant officials from the Shaanxi Energy Bureau and Shaanxi Coal Group were present at the evaluation meeting. This evaluation result fully demonstrates the overall success of this project, from theoretical innovation to practical engineering implementation. 05 Future Prospects: Guiding the Transformation of Coal Power. The successful construction of the Bichang Power Plant not only provides a reliable technical model for the flexible, peak-shaving, clean, and efficient use of the new generation of coal power plants in China, but it also offers key technical support for the development of a new type of power system in the country. The plant will generate 3.3 billion kWh of electricity per year, providing a more stable and sufficient power supply for the grid. Looking ahead to the 15th Five-Year Plan, high-efficiency ultra-supercritical circulating fluidized bed power generation technology will play an even more important role in the development of China’s energy system. Harbin Electric Group also stated that it will continue to adhere to the innovation-driven approach, closely focusing on **strategic plans, and keep making efforts to develop key core technologies. With the successful application of this innovative technology at the Binchang Power Plant in Shaanxi, clean coal power technology has entered a new era. This globally leading technology not only keeps control over energy security firmly in China’s hands, but also sets a new milestone for the green development of global energy. With this authoritative certification, the technology marks a significant breakthrough for our country in the field of efficient and clean power generation.
