The invention relates to a nitrogen inerting method for a B-type fuel cabin, which is divided into three working states, namely nitrogen inerting at an initial stage, nitrogen inerting after fuel leakage and air gasification for maintenance and inspection. Nitrogen inerting in the initial stage is divided into nitrogen inerting in the annular space in the initial stage and nitrogen inerting in the fuel cabin in the initial stage, and nitrogen inerting after fuel leakage is divided into nitrogen inerting in the annular space after fuel leakage and nitrogen inerting in the fuel cabin after fuel leakage. The air formation of the maintenance inspection includes the air formation at the fuel compartment. The device is safe, reliable, suitable for three working states and high in universality, the space of the ship is fully utilized, and arrangement is optimized; and the pipeline combination form is fully utilized, the design requirement of the maintenance system of the LNG B type fuel cabin is effectively met, and the practical value is very high.

    本发明涉及一种B型燃料舱的氮气惰化方法,它分为三个工作状态,分别为初始阶段的氮气惰化、燃料泄漏后的氮气惰化和维护检查的空气化;初始阶段的氮气惰化分为初始阶段的环形空间氮气惰化和初始阶段的燃料舱处所氮气惰化,燃料泄漏后的氮气惰化分为燃料泄漏后的环形空间氮气惰化和燃料泄漏后的燃料舱处所氮气惰化,维护检查的空气化包括燃料舱处所的空气化。本发明安全可靠,适用于三个工作状态,通用性强,充分利用船舶的空间,优化布置;充分利用管路的组合形式,有效解决了LNG B型燃料舱的维护系统设计需求,具有很高的实用价值。
