Abstract:
A gas discharging system for a vessel according to the present invention includes: an engine using natural gas as fuel; a gas valve unit (GVU) for controlling the flow rate of the natural gas supplied to the engine; an exhaust line connected to the engine and the gas valve unit to discharge the fuel gas that is inside the engine and the gas valve unit; and an ejector installed on the exhaust line, wherein the exhaust line extends to a space disposed closer to the stern of the vessel than an engine room and ensures that the gas discharged through the exhaust line is discharged from the stern of the vessel into the atmosphere or seawater. Therefore, the length of the exhaust line is remarkably reduced in length compared to the related art. Also, the gas discharging system for a vessel according to the present invention discharges the fuel gas that remains in the engine and the gas valve unit, but may also transfer the fuel gas to a gas supply part through the exhaust line and the fuel gas discharge line in order to recycle the fuel gas.
