摘要
在船舶动力系统能量转换和利用过程中,实现烟气余热的最大效率回收是降低船舶能效设计指数(EEDI)的有效途径。超临界二氧化碳(sCO_2)发电系统在船舶余热循环利用方面所具有的技术优势已引起全球船舶行业的高度关注,而如何将其与船舶动力系统有机集成并实现高效、稳定联合循环运行发电,正是当前制约该新型技术实船应用的瓶颈。概述了sCO_2布雷顿循环发电的基本原理、典型技术特点及循环结构,分析了国内外研究机构针对sCO_2发电系统在船舶余热循环利用方面的研究现状,探讨了现阶段面向船舶主机余热发电工程化应用所存在的关键技术问题,从而为推进sCO_2布雷顿循环发电技术在船舶烟气余热回收利用领域的基础理论研究和工程方案设计提供理论参考。
In the processes of energy conversion and utilization of ship power systems, the realization of the maximum efficiency recovery of flue gas waste heat was an effective way to reduce the EEDI of the ships. sCO 2 power generation system had the technical advantages of the ship’s waste heat recycling, which caused the global shipbuilding industry’s attention. How to organically integrate sCO 2 power generation system with the ship’s power system to achieve high-efficiency and stable combined-cycle operation of power generation was the bottleneck that currently restricted the applications of the above-mentioned new technology on-board ships. The basic principles, typical technical features and cyclic structure of the sCO 2 Brayton cycle power generation technology were outlined, and the research status of the sCO 2 power generation system for the waste heat recycling of ships at home and abroad was analyzed herein. The key technical problems existing in the engineering applications of waste heat power generation for shipbuilding at the present stage were discussed, which may provide a theoretical reference for the promotion of basic theoretical research and engineering design of sCO 2 Brayton cycle power generation technology in the field of waste heat recovery and utilization of ship flue gas.
