The invention relates to the technical field of ships, in particular to a gas supply system with a recondensation function and a working method.The gas supply system comprises a fuel cabin used for storing LNG; a first gas supply pipeline which comprises an LNG supply pump, a first-stage heat exchanger, a high-pressure pump, a second-stage heat exchanger and a high-pressure vaporizer which are sequentially communicated, the LNG supply pump is communicated with the fuel cabin, and the high-pressure vaporizer is communicated with high-pressure fuel gas equipment; a second gas supply pipeline which comprises a BOG compressor, an inlet of the BOG compressor is communicated with the upper end of the fuel cabin, and an outlet of the BOG compressor is communicated with low-pressure fuel gas equipment; and a condensation pipeline, one end of the condensation pipeline is communicated with an outlet of the BOG compressor, and the other end of the condensation pipeline is communicated with the fuel cabin and an inlet of the BOG compressor. According to the system, the efficiency of cooling and recycling BOG can be ensured while the equipment investment is reduced.

    本发明涉及船舶技术领域,尤其涉及一种具有再冷凝功能的供气系统和工作方法,其包括燃料舱,所述燃料舱用于存放LNG;第一供气管路,所述第一供气管路包括依次连通的LNG供给泵、一级换热器、高压泵、二级换热器和高压气化器,所述LNG供给泵与所述燃料舱连通,所述高压气化器与高压燃气设备连通;第二供气管路,包括BOG压缩机,所述BOG压缩机的进口与所述燃料舱的上端连通,所述BOG压缩机的出口与低压燃气设备连通;冷凝管路,所述冷凝管路的一端与所述BOG压缩机的出口连通,另一端与所述燃料舱和所述BOG压缩机的进口连通。本发明能够降低设备投资的同时,保证对BOG进行冷却回收的效率。
