据东方电气消息，11月25日，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完工发运。 项目预计在2026年实现"双投"，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。 ...

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].
