摘　　要：超临界二氧化碳(S-CO_(2))循环系统发电效率比同参数蒸汽循环高3%~5%,是未来面向与可再生能源共存的化石燃料发电领域重要发展方向.本文从S-CO_(2)循环发电系统产业现状和关键问题等角度,总结了国内外研究进展.有研究表明,通过锅炉模块化设计可将锅炉压降降低到与水蒸气锅炉相当甚至更低的水平,而且复合循环可解决锅炉余热利用问题.在此基础上,不同功率等级的S-CO_(2)循环示范系统为S-CO_(2)锅炉质量评价技术体系研究奠定理论和技术基础.The power generation efficiency of supercritical carbon dioxide(S-CO_(2))cycle is 3%~5%higher than that of steam cycle with the same parameters,which is an important development direction in the field of fossil fuel power generation in the future.This paper summarizes the research progress of S-CO_(2)cycle power generation system from the perspective of industry status and key issues.Some studies have shown that through the modular design of boiler,the pressure drop of boiler can be reduced to the same or even lower level as that of steam boiler,and the connected-top-bottom-cycle can solve the waste heat utilization problem.On this basis,the demonstration S-CO_(2)power system in different power scales lays a theoretical and technical foundation for the research of S-CO_(2)boiler quality evaluation technology system.
