Disclosed are a system and a method for supplying fuel gas using the waste heat of engine-cooling water in a ship. The system for supplying fuel gas using the waste heat of engine-cooling water in a ship according to the present invention comprises: a cooling water circulating part having a main flow path where the heat source of cooling water for cooling an engine flows; a liquefied gas vaporizing part including a vaporizer for vaporizing liquefied gas into fuel gas and a heat exchanger for heating heat-exchanging fluid discharged from the vaporizer; and a transmission part of the heat source of cooling water for transmitting the heat source of the cooling water, which is supplied from the cooling water circulating part, to the liquefied gas vaporizing part, and allowing the heat source of the cooling water to exchange heat with the heat-exchanging fluid. The transmission part of the heat source of cooling water supplies the heat source of the cooling water, which is discharged from an engine, to the heat exchanger if the temperature of the heat-exchanging fluid discharged from the heat exchanger is lower than or equal to a preset temperature, and returns the heat source of the cooling water to a main flow path by bypassing the heat exchanger if the temperature of the heat-exchanging fluid is higher than the preset temperature.

    선박의 엔진 냉각수의 폐열을 이용한 연료가스 공급시스템 및 방법이 개시된다. 본 발명의 선박의 엔진 냉각수의 폐열을 이용한 연료가스 공급시스템은, 엔진의 냉각을 위한 냉각수 열원이 흐르는 메인유로를 갖춘 냉각수 순환부; 액화가스를 연료 가스로 기화시키는 기화기와, 기화기에서 배출되는 열교환 유체를 가열시키는 열교환기가 구비된 액화가스 기화부; 및 냉각수 순환부로부터 제공되는 냉각수 열원을 액화가스 기화부로 전달하여 열교환 유체와 열교환시키는 냉각수 열원 전달부를 포함하며, 냉각수 열원 전달부는, 열교환기에서 배출되는 열교환 유체의 온도가 미리 설정된 온도 이하인 경우 열교환기로 엔진에서 배출되는 냉각수 열원을 공급하고, 열교환 유체의 온도가 미리 설정된 온도를 초과하는 경우 열교환기를 바이패스하여 냉각수 열원을 메인유로로 복귀시키는 것을 특징으로 한다.
