Disclosed is an exhaust gas waste heat recovery system for a ship. The exhaust gas waste heat recovery system for a ship according to the present invention comprises: a heat medium circulation line through which a working fluid circulates, the heat medium circulation line being provided on the ship; a vaporizer which is provided in the heat medium circulation line and in which the working fluid is vaporized by exchanging heat with exhaust gas discharged from the engine of the ship; and a turbo expander provided in the heat medium circulation line and producing shaft power while receiving and expanding a working fluid, in which the engine receives a low flash point liquefied gas as a fuel and the working fluid circulates in the heat medium circulation line of a closed loop, meanwhile, a phase change from liquid to gas is caused by using, as a heat source, exhaust gas discharged from an engine by using a low-flash-point liquefied gas as a fuel.
公开一种船舶的废气余热回收系统。本发明的船舶的废气余热回收系统包括:热介质循环管线,设置于船舶上且工作流体经由所述热介质循环管线循环;气化器,设置于热介质循环管线中,且在气化器中,工作流体通过与从船舶的发动机排出的废气进行热交换而被气化;以及透平膨胀机,设置于热介质循环管线中,且在接收工作流体且使工作流体膨胀的同时生产轴功率,其中发动机发动机接收低闪点液化气体作为燃料,且工作流体在闭合回路的热介质循环管线中循环,同时使用通过使用低闪点液化气体作为燃料从发动机排出的废气作为热源而引起从液体到气体的相变。
