PURPOSE: A vessel propelled by liquefied fuel gas is provided to effectively utilize vaporized heat with a separately operating refrigeration facility when the vessel is not propelled by the liquefied fuel gas. CONSTITUTION: A vessel propelled by liquefied fuel gas comprises a vaporizer(20), a propeller(30), a propelling heat exchanger(40), a fan cooler(50), a vaporizer connection pipe(60), and a vaporizer valve unit(70). The vaporizer vaporizes the liquefied fuel gas in a liquefied fuel gas tank(10). The vaporized LPG is supplied to the propeller. The propelling heat exchanger absorbs heat generated from the vaporizer when the propeller operates. The propelling heat exchanger exchanges the heat with first working fluid which circulates in the vaporizer. The fan cooler exchanges the heat with the first working fluid in order to utilize the vaporized heat of the vaporizer when the propeller operates. The vaporizer connection pipe connects the fan cooler, the propelling heat exchanger, and the vaporizer to each other. The vaporizer valve unit is installed in the vaporizer connection pipe. The vaporizer valve unit selectively allows and cuts off the flow of the first working fluid to the propelling heat exchanger and fan cooler. |
