Personnel in charge of relevant departments at Dongfang Boiler, the Sichuan Special Equipment Inspection and Research Institute, Hengshui Zhongke Hengfa Power Equipment Co., Ltd. and other organizations attended the evaluation meeting. The Hengshui Zhongke supercritical CO₂ boiler is a project that provides a heat source for the development of complete CO₂ Brayton cycle power generation units. Compared with traditional supercritical boilers that use water as the working fluid, this boiler features a different working fluid, as well as changes in the boiler design and the arrangement of the heating surfaces resulting from this change in working fluid. The supercritical CO₂ boiler for this project was independently developed by Dongfang Boiler. After its construction, tests related to heat transfer, flow dynamics, and materials of supercritical CO₂ boilers were carried out using the Zhongke Hengfa experimental unit. As a result, the principles and methods for a new type of high-efficiency power generation system based on the supercritical CO₂ cycle were established, thereby promoting the application of the supercritical CO₂ Brayton cycle in the field of power generation. Supercritical carbon dioxide power generation technology is still in its infancy in China. Dongfang Boiler actively explores new technological directions in the field of power generation equipment, leading the trends in this industry; it is one of the first companies and institutions in the country to conduct research on supercritical carbon dioxide power cycles. In recent years, Dongfang Boiler has undertaken numerous research projects related to supercritical carbon dioxide power generation technology, and has collaborated with various enterprises and universities on studies in this field. The supercritical carbon dioxide boiler that has passed the evaluation is one of the outcomes of these research efforts. It represents a response to the urgent need for efficient and clean power generation, taking advantage of the key technological development opportunities associated with S-CO₂ in order to achieve rapid progress and meet the strategic goals for power generation technology in the medium to long term. Since its establishment, the project team at Zhongke Hengfa has been committed to diligent research and development. In 2018, they successfully developed and assembled China’s first megawatt-class supercritical carbon dioxide compressor; in 2019, they established the only megawatt-class general testing platform for supercritical carbon dioxide fluid machinery in the country; and in 2021, a demonstration unit for supercritical carbon dioxide power generation was completed and put into operation. Achievements in related technologies such as printed circuit board heat exchanger design and additive manufacturing, as well as air-source heat pumps, have also been initially commercialized.
