The present invention relates to a system and a method for supplying a heat source for vaporizing liquefied gas to a vaporizer and, more specifically, relates to a system and a method for supplying a heat source for vaporizing liquefied fuel to minimize a heat source wasted in a ship and to prevent environmental pollution. The system for supplying a heat source for vaporizing liquefied fuel according to the present invention comprises: a vaporizer which vaporizes liquefied fuel; a steam heater which heats a heating intermediate medium heat-exchanged with the liquefied fuel in the vaporizer by using steam; and an electric heater which heats the heating intermediate medium by using electricity. A heat source which vaporizes the liquefied fuel is selected in accordance with vaporization requirement by control of heating the heating intermediate medium by any one of the steam heater and the electric heater. 본 발명은 액화가스를 기화시키는 열원을 기화기로 공급하는 시스템 및 방법에 관한 것으로, 특히 선박에서 버려지는 열원을 최소화하고 환경오염을 방지할 수 있는 액화연료 기화 열원 공급 시스템 및 방법에 관한 것이다. 본 발명에 따른 액화연료 기화 열원 공급 시스템 및 방법은, 액화연료를 기화시키는 기화기(Vaporizer); 상기 기화기에서 액화연료와 열교환하는 중간매체(Heating Intermediate Medium)를 스팀을 이용하여 가열하는 스팀히터(Steam Heater); 및 상기 중간매체를 전기를 이용하여 가열하는 전기히터(Electric Heater);를 포함하고, 상기 중간매체가 상기 스팀히터 및 전기히터 중 어느 하나에 의해 가열되도록 제어되어 상기 액화연료를 기화시키는 열원이 기화요구량에 따라 선택되는 것을 특징으로 한다.
