World's First 650°C High-Efficiency Ultra-Supercritical Coal-Fired Boiler Enters Full Construction Phase

The world's first 650°C high-efficiency ultra-supercritical coal-fired power boiler recently completed its first concrete pouring at Huaneng Yuhuan Power Plant, marking the commencement of full-scale construction. This boiler is the first equipment approved by the State Administration for Market Regulation to enter sandbox testing since the implementation of China's special equipment safety sandbox supervision system.

This breakthrough project achieves the global milestone of elevating coal-fired power unit steam temperature to 650°C - the highest worldwide. By adopting China's independently developed complete series of new high-temperature alloy materials, it overcomes critical technical bottlenecks in high-temperature alloys and achieves complete self-sufficiency in key high-temperature material technology. This represents a major advancement in China's new high-temperature resistant materials and clean, efficient coal power utilization technologies.

Upon completion, the boiler will set new world records for the highest operating parameters and lowest coal consumption in thermal power units, significantly enhancing clean and efficient coal power utilization. It will provide crucial technical support for China's efforts to achieve its "Dual Carbon" goals.

Boilers are China's highest energy-consuming equipment with the largest carbon emissions, accounting for over 40% of national emissions. The research and application of new high-temperature and high-pressure resistant materials serve as the primary pathway for boilers to reduce energy consumption, lower carbon emissions, and consequently contribute to achieving the "Dual Carbon" goals.
