破解火电厂供热发电“两难” 我国最大“火电熔盐储热”项目投运

Core Insights - The largest "thermal power molten salt heat storage" project in China has been fully operational at the Suzhou Power Plant in Anhui, effectively addressing the dual challenges of heating and power generation in thermal power plants [1] Group 1: Project Overview - The molten salt heat storage system acts like a "thermal battery" for thermal power units, storing excess heat during low demand and releasing it during peak demand, thus preventing energy waste [1] - The project utilizes two molten salt storage tanks operating at high temperatures of 390°C and low temperatures of 190°C, with a designed heat storage capacity of 1,000 MWh [1] Group 2: Technical Achievements - The successful operation of the molten salt heat storage project signifies a breakthrough in combined heat and power technology, allowing the unit to provide continuous heating for 4 hours at full load and 5 hours at 30% load [1] - The external heating capacity has increased to 410 tons per hour, an improvement of 260 tons per hour compared to previous capabilities [1]
