摘　　要：介绍采用蒸汽动力装置的液化天然气(Liquefied Natural Gas,LNG)运输船燃料的应用概况和相关政策背景,阐述船舶中可进行LNG冷能开发利用的客观条件。对LNG冷能发电的几种方法进行优劣分析,设计出LNG冷能发电系统。给出、效率和相对效率的计算模型,运用流程模拟计算软件得出不同条件下可发电的功率、效率和相对效率。计算结果表明:采用冷能发电系统后,船舶每年可产生大量电能和节约大量营运费用,可获得非常好的经济效益。The application profiles and relevant policy background of LNG carrier fuel steam power plant are introduced and the objective conditions for the development and utilization of LNG cold energy is described. Several methods of LNG cold energy power generation are compared in their advantages and disadvantages and the LNG cold energy system is designed for generating electricity. The computational models of exergy, exergy efficiency and relative exergy efficiency are given and the power generation, the exergy efficiency and the relative exergy efficiency under different conditions are obtained by means of process simulation software. The calculation result shows that the cold energy generation system on LNG carrier will produce great amonunt of electric energy and reduce ship operating costs, which has significant economic benefits.
