The present invention provides a dual-pipe ventilation system for supplying fuel gas to a dual-fuel engine which can greatly improve the safety and efficiency of a ventilation system of a ship to which a dual-fuel engine is applied. According to one embodiment of the present invention, the dual-pipe ventilation system for supplying fuel gas to a dual-fuel engine comprises: an engine room in which a plurality of generating engines are arranged; a gas valve unit room in which a plurality of gas valve units are arranged; a fuel preparation room provided to supply the fuel gas to the engine room; and a non-hazardous open area spatially separated from the engine room and the gas valve unit room, and supplying air to the engine room. Air is supplied from the non-hazardous open area to the generating engines through an inlet pipe. The air supplied to the generating engines is supplied to the gas valve unit room through a dual pipe connecting the generating engines and the gas valve unit room. The inlet of the inlet pipe supplying air to the engine room can be arranged in the non-hazardous open area.
이중연료엔진에 연료가스를 공급하는 이중배관의 환기 시스템이 제공된다. 일 실시예에 있어서, 이중연료엔진에 연료가스를 공급하는 이중배관의 환기 시스템에 있어서, 복수의 발전엔진(generating engine)이 내부에 배치되는 엔진룸; 복수의 가스밸브유닛(gas valve unit)이 내부에 배치되는 가스밸브유닛룸; 상기 엔진룸으로 상기 연료가스를 공급하기 위해 마련된 연료준비룸; 및 상기 엔진룸 및 상기 가스밸브유닛룸과 공간적으로 분리되며, 상기 엔진룸에 에어를 공급하는 비위험개방영역(non-hazardous open area);을 포함하고, 에어가 유입배관을 통해 상기 비위험개방영역에서 상기 발전엔진으로 공급되며, 상기 발전엔진으로 공급된 에어는 상기 발전엔진과 상기 가스밸브유닛룸을 연결하는 이중배관을 통해 상기 가스밸브유닛룸으로 공급되고, 에어를 상기 엔진룸으로 공급하는 유입배관입구는 상기 비위험개방영역에 배치될 수 있다.
