成品油轮惰气发生器(IGG)系统原理及管理建议

Work principle and management of inert gas generator(IGG) system on Products tanker

惰性气体发生器(IGG)在成品油轮上主要是向货舱提供一定压力和含氧量的惰性气体,置换出可燃性气体以及在舱内安全作业时提供新鲜空气。本文基于某轮惰气发生器(IGG)系统—挪威Air Products AS,阐述系统的组成、工作原理以及主要部件的作用。同时根据笔者的工作经验,介绍了此系统的典型故障处理以及常规维护保养。

Inert gas generator is designed to process supplies of fuel oil and air into inert gas for cargo tanks, inert gas generator is designed to gas-freed by diluting with fresh air for safety work else. The paper based on Air-Products AS analyzed inert gas generator （IGG） system work principle .process and functions of main components. According to author＇s experience onboard, expounded the measures about inert gas generator （IGG） system＇s troubleshooting and maintenance.
