船舶动力装置选型及经济性研究

Research on type selection and economy of marine power plant

介绍核动力装置、燃气轮机、汽轮机和柴油机等动力装置的技术特点及其在船舶领域的应用,并对其经济性进行研究,重点对船舶动力装置的未来发展方向进行展望。在中小型船舶中,柴油机仍将占据主要地位;在中型船舶中,汽轮机、燃气轮机和柴油机各自占据一席之地;在大型船舶中,动力装置多以汽轮机和燃气轮机为主。考虑技术成熟度和安全性等方面的原因,核动力装置在民用船舶领域的应用相对较少,主要被应用于破冰船等特殊领域。

Introduce the technical characteristics of nuclear power plant,gas turbine,steam turbine,diesel engine and other power plants and their applications in the field of ships,study their economics,and look forward to the future development direction of marine power plants.In small and medium-sized ships,diesel engines will still play a major role.In medium-sized ships,steam turbines,gas turbines and diesel engines will occupy their respective places.While in largesized ships,steam turbines and gas turbines are mainly used.Considering the reasons of technical maturity and safety,nuclear power devices are relatively less used in the field of civil ships,mainly in special fields such as icebreakers.
