双燃料大型集装箱船LNG燃料供气系统设计
|
摘要
液化天然气(LNG)以低温常压形式储存,喷入主机燃烧之前需经过供气系统进行处理,将其转换成具有合适温度压力的气体燃料。燃料供气系统性能的好坏直接影响燃气质量,进而影响设备运行效率。以20 000箱LNG/柴油双燃料远洋大型集装箱船为研究对象,对LNG气体燃料供气系统进行深入研究。结合供气系统工作流程,充分分析供气系统组成及各部分功能,并对方案中关键设备进行选型研究,提出供气系统完整设计方案,设计方案满足实际使用需求并可为相关设计提供参考。
Liquefied natural gas(LNG) is stored in the form of low temperature and normal pressure. Before being injected into the host, LNG needs to be processed by the gas supply system to convert it into gas fuel with a suitable temperature and pressure. The performance of the fuel gas supply system directly affects the gas quality, which in turn affects the equipment operating efficiency. Taking 20 000 cases of LNG/diesel dual-fuel ocean-going large-scale container ships as research objects, the LNG gas fuel gas supply system was further studied in depth. Combined with the work process of the gas supply system, the composition of the gas supply system and the functions of each part were fully analyzed, the selection of key equipment in the plan was studied, and a complete design scheme for the gas supply system was proposed. The design meets actual need and provides a reference for related design.
