LNG船舶燃气双壁管通风系统

The Ventilation System with Double Wall Piping of the LNG Vessels'Fuel Gas System

考虑纯LNG船舶和双燃料船舶燃料系统泄漏率及安全级别的差异,采用燃气双壁管通风系统,通过负压通风,有效排除内壁管及燃料罐泄露的气体,保证整个燃料供气系统的安全性。介绍LNG燃料主机最重要的燃气双壁管通风系统,LNG燃料作为一种清洁、安全、高效的可替代燃料,适应当前市场及环保需求,将在未来船舶及海工项目上广泛应用。

Based on the consideration of security level and leakage rate of the pure LNG vessels and dual fuel vessels’fuel system,the ventilation system with the double wall piping of gas system was adopted.It can extract out the leaking gases from the internal piping and fuel tank,so as to guarantee the security level of the whole fuel supply system,by the ventilation under a negative pressure.The most important ventilation system for the double wall piping of LNG vessels’fuel gas system was introduced.The LNG fuel as a clean,safe and effective alternative fuels,is adapted to the current market and the requirements of environmental protection well,will be widely used in the future vessels and ocean engineering projects.
