摘要
为实现当今国际对于提高能源利用率、节能减排的目标,介绍了超临界二氧化碳(sCO_2)的基本特点,描述了其在发电领域的4大应用方向(含碳原料火力发电、核反应堆、太阳能光热和余热回收),概括了sCO_2用于发电领域的现阶段研发、试验、示范状况,并总结了sCO_2用于电力行业的现有瓶颈、技术挑战和研究方向。结果表明:不同的sCO_2循环系统中都存在还未完全解决的核心问题:如sCO_2对材料的腐蚀特性、sCO_2系统设计和设备选型、高效微通道换热器的设计及制造、新型sCO_2透平、压缩机和燃机的研发。在材料、循环系统高效设计以及关键设备设计制造等瓶颈有所改善或突破后,sCO_2会在民用发电、军工、舰船等行业得到广泛应用。
In order to realize the global goals of adjusting, optimizing the industrial structure, enhancing the energy efficiency, saving energy and reducing emission,the basic characteristics of sCO2 were overviewed. Four aspects,i, e. , electricity generation using carbonaceous ma- terial, nuclear reactor, solar power and waste heat recovery, concerning the sCO2 ＂s application in power field were described. The current research, experiment and demonstration were summarized. The bottle-neck, technical challenge and future research aspects of developing sCO2 were proposed. Results show that all different sCO2 cycling systems have critical problems that have not been totally solved, such as corrosion of sCO2 to materials, system design and type-choosing of sCO2 cycling system, design and manufacture of high-efficiency micro- channel circuit heat exchanger, research and development of new-type sCO2 turbine, compressor and gas turbine. The sCO2 is able to be widely used in power industry, military and ship project after improvement and breakthrough of material, design of high efficiency cycling system, fabrication of key equipment.
