Core Viewpoint - The world's first 650°C ultra-supercritical coal-fired power generation unit is under construction at Huaneng Yuhuan Power Plant, marking a significant advancement in coal power technology aimed at improving efficiency and reducing emissions [1]. Group 1: Project Overview - The Huaneng Yuhuan Power Plant Phase IV project involves the construction of a 1 million kilowatt 650°C ultra-supercritical once-through coal-fired power generation unit [1]. - The design parameters include a main steam pressure of 35 MPa and both main and reheated steam temperatures reaching 650°C, representing the highest specifications for coal-fired units globally [1]. Group 2: Efficiency and Environmental Impact - The new 650°C ultra-supercritical coal-fired unit is expected to enhance power generation efficiency by approximately 4 percentage points compared to existing units [1]. - The coal consumption per kilowatt-hour is projected to decrease by about 10%, leading to an annual reduction of approximately 450,000 tons of carbon dioxide emissions [1]. Group 3: Technological Innovation - This project is a major national scientific and technological initiative, utilizing high-temperature alloy materials developed by China Huaneng, which possess independent intellectual property rights [1]. - The project aims to overcome traditional thermal efficiency limitations in coal-fired power generation, enabling the production of more electricity with less coal [1]. Group 4: Strategic Importance - Upon completion, the project will significantly enhance the clean and efficient utilization of coal power and promote the upgrade of domestic high-end equipment manufacturing capabilities [1]. - It will provide crucial support for China's energy security and the achievement of dual carbon goals [1].
