12月4日，记者从东方电气集团东方汽轮机有限公司（以下简称"东方汽轮机"）获悉，由该公司制造的 世界首台套630℃超超临界二次再热国家电力示范项目主设备，日前在四川德阳下线发运。 同时，机组中自主研发的C630R转子，由钢铁研究总院有限公司、中国第二重型机械集团有限公司、东 方汽轮机等单位联合攻关。研发团队突破国外高压转子传统技术路径，采用全新成分设计思路，使性能 指标全面优于国外同类产品，其中630℃外推10万小时持久强度达到122兆帕。 同时，该机组采用的带功率平衡发电机双机回热系统，通过显著提高回热抽汽能级利用效率，精准解决 了高参数机组高加换热温差增大引发的换热不可逆损失问题，在提升机组整体效率的同时，进一步增强 了运行的可靠性与经济性。 据了解，该示范项目投产后，年发电量可达100亿千瓦时，较常规机组年节约标煤35万吨、减排二氧化 碳94.5万吨。 该示范项目配置两台由东方汽轮机研制提供的100万千瓦机组。该机组拥有4项全球纪录：一次及二次再 热进汽温达631℃、主蒸汽压力达35.5兆帕、发电热效率突破50%、供电煤耗低至256.28克/千瓦时，是 目前全世界"温度最高、压力最高、效率最高、煤耗最低 ...

Core Viewpoint - The world's first 630℃ ultra-supercritical secondary reheating power generation equipment, developed by Dongfang Electric Group's subsidiary, has been successfully manufactured and is set to be delivered to the Datang Yuncheng National Power Demonstration Project in Shandong, showcasing significant advancements in thermal power technology [1][2]. Group 1: Project Overview - The project features two 1 million kilowatt units with a primary and secondary reheating steam temperature of 631℃, a main steam pressure of 35.5 MPa, a power generation thermal efficiency exceeding 50%, and a coal consumption rate as low as 256.28 grams per kilowatt-hour, making it the highest in pressure, temperature, efficiency, and lowest in coal consumption globally for a single-shaft million-kilowatt secondary reheating thermal power unit [1]. - The project is expected to achieve dual investment in the first half of 2026, with an annual power generation capacity of 10 billion kilowatt-hours, saving 350,000 tons of standard coal and reducing carbon dioxide emissions by 945,000 tons compared to conventional units [1]. Group 2: Technological Innovations - The development team utilized titanium alloy materials instead of traditional steel to withstand the immense centrifugal forces generated by long blades, achieving a significant leap in steam flow and energy conversion efficiency through innovative aerodynamic designs [2]. - The C630R rotor, developed through collaboration among several institutions, surpassed traditional foreign high-pressure rotor technologies, achieving a long-term strength of 122 MPa at 630℃ for 100,000 hours [2]. - The project employs a dual-machine regenerative system with power balance generators, representing the forefront of thermal power technology, which enhances overall efficiency and reliability while addressing heat exchange losses [3].
