【Ten Years of Great Progress in Chemical Engineering Technology】059 – China’s first demonstration project for peak shaving and frequency regulation using coal-fired power units coupled with steam-salt thermal storage, 2023

Thread Content

Ten years of rapid development in chemical engineering technology; praise for the prosperous and strong China. This is just a starting point to encourage more participation from everyone. HaiChuan becomes even better with your involvement – we welcome all to join in the forum discussions. Everyone should focus on safety and know how to handle emergencies. ********************************************* China’s first demonstration project featuring coal-fired power units combined with steam-salt thermal storage for peak shaving and frequency regulation has been successfully put into operation – the first of its kind in the country! The 660,000-kilowatt coal-fired power unit demonstration project incorporating steam-salt thermal storage for peak shaving and frequency regulation was successfully put into operation. On May 15, 2023, the first such project in China – developed independently by China Huaneng Group Co., Ltd. – was launched at Huaneng Weijiamao Coal Power Company. The project has a heat storage capacity of 80 megawatt-hours; the unit can be adjusted to a minimum of 20% of its rated load, and the load response rate can increase by more than 0.5% of the rated load per minute, thereby significantly enhancing the unit’s frequency regulation capability. This project fills the technical gap in China regarding the use of \"molten salt heat storage + hot water heat storage\" to assist coal-fired power plants in peak shaving and frequency regulation, providing a new approach for such plants to undergo flexibility upgrades and enhance their capabilities in these areas.
