The present invention relates to a fuel supply system for a liquefied petroleum gas (LPG) fuel ship and a method thereof, which can effectively supply LPG fuel to an LPG fuel engine of a ship using LPG as fuel. To this end, the fuel supply system for an LPG carrier according to the present invention comprises: an LPG storage tank storing LPG; an engine using the LPG as fuel; a high-pressure pump which compresses the LPG discharged by the LPG storage tank at a pressure required by the engine; and a fuel heating unit which heats the LPG which is to be supplied as the fuel of the engine. The fuel heating unit comprises: a fuel return line which collects the LPG fuel of a high temperature and a high pressure which includes impurities and is returned from the engine; and an auxiliary heater which heats the LPG to be supplied to the engine by using the surplus LPG, which is returned from the engine along the fuel return line, as a heating medium.

    본 발명은 LPG를 연료로 사용하는 선박의 LPG 연료 엔진으로 LPG 연료를 효과적으로 공급할 수 있는 LPG 연료 선박의 연료 공급 시스템 및 방법에 관한 것이다. 본 발명에 따른 LPG 운반선의 연료 공급 시스템은, LPG(Liquefied Petroleum Gas)를 저장하는 LPG 저장탱크; LPG를 연료로 사용하는 엔진; 상기 LPG 저장탱크로부터 배출된 LPG를 상기 엔진에서 요구하는 압력으로 압축시키는 고압펌프; 및 상기 엔진의 연료로 공급할 LPG를 가열하는 연료 가열부;를 포함하고, 상기 연료 가열부는, 상기 엔진으로부터 회수되는 불순물을 포함하는 고온고압의 LPG 연료를 회수하는 연료 회수라인; 및 상기 연료 회수라인을 따라 상기 엔진으로부터 회수되는 잉여의 LPG를 가열매체로 하여, 상기 엔진으로 공급할 LPG를 가열하는 보조히터;를 포함한다.
