6月30日，华能650℃燃煤发电示范项目技术方案评审会在雄安新区召开，中国工程院院士岳光溪、高翔，来自清华大学、浙江大学、上海交通大学、哈尔滨工业大学、中国科学院、电力规划设计总院等能源与材料领域专家学者共同为项目“把脉定向”。

On June 30th, a technical scheme review meeting for the 650°C coal-fired power generation demonstration project of Huaneng was held in Xiong'an New Area. Academicians Yue Guangxi and Gao Xiang from the Chinese Academy of Engineering, as well as experts from Tsinghua University, Zhejiang University, Shanghai Jiao Tong University, Harbin Institute of Technology, the Chinese Academy of Sciences, and the Electric Power Planning and Design General Institute in the fields of energy and materials, jointly provided guidance and direction for the project.

会议听取了项目研发单位和制造单位关于650℃燃煤发电示范项目技术方案的汇报，并围绕HT700材料工程适配性、锅炉汽轮机主机设计制造难点、全厂热力系统优化三大核心议题开展评审。

The meeting heard the reports from the project research and development unit and the manufacturing unit on the technical plan for the 650℃ coal-fired power generation demonstration project, and conducted reviews on three core issues: the engineering compatibility of HT700 material, the design and manufacturing difficulties of the boiler and turbine main units, and the optimization of the entire plant's thermal system.

与会院士、专家对华能650℃燃煤发电示范项目所取得的成果给予高度评价，一致认为华能650℃燃煤发电示范项目锅炉、汽轮机和项目整体设计方案总体合理可行，HT700系列高温材料研发与工程应用基础扎实，各项主要性能指标先进，这标志着燃煤机组参数、效率以及煤耗迈上新台阶，是推动科技创新与产业创新深度融合的良好示范。

The participating academicians and experts highly praised the achievements of Huaneng's 650°C coal-fired power generation demonstration project. They unanimously agreed that the boiler, turbine and overall design scheme of the Huaneng 650°C coal-fired power generation demonstration project were overall reasonable and feasible. The HT700 series of high-temperature materials had a solid foundation for research and application, and all the main performance indicators were advanced. This marked that the parameters, efficiency and coal consumption of coal-fired power units had reached new levels, and it was a good demonstration for promoting the deep integration of scientific and technological innovation and industrial innovation.

据悉，作为新一代煤电机组的代表性技术，650℃煤电技术可显著提高发电效率、降低机组煤耗、减少碳排放水平，支撑煤电在新型电力系统中更好发挥兜底保障和支撑调节作用。

It is known that the 650°C coal power technology, as a representative technology of the new generation of coal-fired power plants, can significantly enhance power generation efficiency, reduce the coal consumption of the units, and decrease carbon emission levels. This technology can support coal power to better play its role as a backup guarantee and regulatory support in the new power system.

中国华能联合35家单位组建创新联合体，于2010年牵头开启国产铁镍基高温合金创新攻关之路，并在华能玉环电厂率先开展650℃燃煤发电示范项目。全球首台650℃燃煤发电示范项目——华能玉环电厂四期项目于2025年11月8日开工建设，目前已进入关键攻坚阶段。该项目主蒸汽和再热蒸汽温度均达到650℃，设计主蒸汽压力达到35兆帕，是目前全球范围内燃煤机组最高参数。

China Huaneng has jointly formed an innovation consortium with 35 other entities. In 2010, it took the lead in initiating the innovation research on domestic iron-nickel-based high-temperature alloys, and first carried out a 650℃ coal-fired power generation demonstration project at Huaneng Yuhuan Power Plant. The world's first 650℃ coal-fired power generation demonstration project - the fourth phase project of Huaneng Yuhuan Power Plant - started construction on November 8, 2025 and has now entered the critical攻坚stage. The main steam and reheated steam temperatures of this project both reach 650℃， and the designed main steam pressure reaches 35 megapascals， which is the highest parameter for coal-fired units in the world at present.

评审会当天，全球首台650℃燃煤发电示范项目迎来重大突破，项目首件汽轮机高压内杠、中压调门顺利完成铸造，首批高温合金无缝管顺利完成全流程生产与检验验收。这标志着我国已全面掌握650℃高参数煤电核心高温材料成套生产技术，相关产业链关键环节实现自主可控，填补了全球高端煤电特种材料领域空白。

On the day of the review meeting, the world's first 650℃ coal-fired power generation demonstration project achieved a major breakthrough. The first steam turbine high-pressure inner tube and medium-pressure regulating valve of the project were successfully cast, and the first batch of high-temperature alloy seamless tubes were successfully completed throughout the production process and passed the inspection and acceptance. This indicates that China has fully mastered the complete production technology of core high-temperature materials for 650℃ high-parameter coal power, and the key links of the related industrial chain have achieved independent control, filling the gap in the global high-end coal power special materials field.

会议建议，下阶段要以清洁低碳、安全可靠、高效调节、造价领先为目标，进一步完善材料应用优化、主机方案设计、系统优化设计，确保完成示范任务攻关，并以此为基础开展700℃技术研发，推动煤电向更高参数、更高效率迭代升级，全力构建高效、绿色、灵活的新一代煤电体系，助力“双碳”目标实现。

The meeting suggested that in the next stage, the goal should be set as clean and low-carbon, safe and reliable, efficient regulation, and cost leadership. Further improvements should be made in material application optimization, main unit scheme design, and system optimization design to ensure the completion of the demonstration task research and breakthroughs. Based on this, 700℃ technology research and development should be carried out to promote the iterative upgrading of coal power to higher parameters and higher efficiency, and to fully build a new generation of coal power system that is efficient, green, and flexible, thereby helping to achieve the "carbon neutrality" goal.
