LIQUIFIED FUEL GAS PROPULSION SHIP

摘要

PURPOSE: A ship propelled by liquefied fuel gas is provided to efficiently utilize vaporized heat generated when the liquefied fuel gas is vaporized. CONSTITUTION: A ship propelled by liquefied fuel gas comprises a liquefied fuel supply line (105), a vaporizer (110), a first heat exchanger (120), a fuel heater (130), and a second heat exchanger (140). The liquefied fuel supply line connects a liquefied fuel tank (101) and a thruster (102). The vaporizer is connected to the liquefied fuel supply line to vaporize the liquefied fuel gas. The first heat exchanger circulates first working fluid to the vaporizer. The fuel heater is installed in the liquefied fuel supply line between the vaporizer and the thruster to heat the liquefied fuel gas vaporized by the vaporizer. The second heat exchanger circulates second working fluid to the fuel heater.
