超级赛道，爆发！“超碳一号”如何发电？

Core Viewpoint - The successful operation of the world's first commercial supercritical carbon dioxide power generation unit, "Super Carbon No. 1," marks a significant advancement in efficient power generation technology, utilizing supercritical carbon dioxide as a new working medium, which has broad commercial prospects [1][3]. Group 1: Technology and Performance - "Super Carbon No. 1" has transitioned from traditional steam power generation to using supercritical carbon dioxide, enhancing power generation performance metrics [1]. - The technology achieves over 85% improvement in waste heat utilization and more than 50% increase in net power generation compared to existing steam power generation technologies [3]. - The supercritical carbon dioxide power generation process involves compressing, heating, expanding, and cooling, which allows for a more efficient energy conversion compared to conventional methods [15]. Group 2: Economic Impact - The project is expected to generate an annual cash flow increase of nearly 50 million yuan, allowing for investment cost recovery within three years [5]. - The market potential for retrofitting existing waste heat recovery systems in the steel metallurgy industry is estimated to be around 100 billion yuan, with over 300 sets of traditional sintering machines eligible for modification [23]. Group 3: Future Applications - Future applications of supercritical carbon dioxide power generation technology include integration with molten salt energy storage systems, particularly in wind and solar energy scenarios, with a demonstration project set to begin in Xinjiang in 2026 [19]. - The technology is also anticipated to be beneficial in offshore oil and gas drilling platforms and large vessels, where space-saving equipment is crucial, potentially reducing equipment size to one-fourth of conventional systems [21].
