A ship exhaust gas waste heat recovery system is disclosed. The ship exhaust gas waste heat recovery system of the present invention comprises: a heat medium circulation line provided on a ship and through which a working fluid circulates; a vaporizer provided in the heat medium circulation line and vaporizing the working fluid through heat exchange with exhaust gas discharged from the engine of the ship; and an expansion turbine provided in the heat medium circulation line and producing axial power by receiving and expanding the working fluid. The engine is supplied with low flash point liquefied gas as fuel. The working fluid uses the low flash point liquefied gas as fuel, changes phase from liquid to gas using the exhaust gas discharged from the engine as a heat source, and circulates in a closed loop heat medium circulation line. Therefore, the energy efficiency of a ship can be improved.
선박의 배기가스 폐열회수시스템이 개시된다. 본 발명의 선박의 배기가스 폐열회수시스템은, 선박에 마련되며 작동유체가 순환하는 열매체순환라인; 상기 열매체순환라인에 마련되며 상기 작동유체가 상기 선박의 엔진에서 배출되는 배기가스와 열교환으로 기화되는 기화기; 및 상기 열매체순환라인에 마련되며 상기 작동유체를 공급받아 팽창시키면서 축동력을 생산하는 팽창터빈:을 포함하고, 상기 엔진은 저인화점 액화가스를 연료로 공급받고, 상기 작동유체는 상기 저인화점 액화가스를 연료로 하여 상기 엔진에서 배출되는 배기가스를 열원으로 액체에서 기체로 상변화되면서 폐루프(closed loop)의 열매체순환라인을 순환하는 것을 특징으로 한다.
