<p>PROBLEM TO BE SOLVED: To provide a technique for heating a working fluid in a working fluid storage tank by a heat exchanger using waste heat of a ship engine, controlling a vaporization quantity of LNG vaporized in the working fluid storage tank under a working fluid flow volume control, and quickly respond to a request output from the ship engine.SOLUTION: A working fluid storage tank 200 includes: a casing 210 that is hermetically sealed by a bottom plate 211 and a top plate 212, and in which a working fluid inlet port 213 and a working fluid outlet port 214 are formed; an inlet-side tube sheet 220 coupled to a first supply line coupled to an LNG fuel tank; an outlet-side tube sheet 230 coupled to a fuel supply line to be distanced from the inlet-side tube sheet 220; a main tube 240 for allowing LNG to be vaporized; and an auxiliary tube 250 configured such that the LNG flowing via a second supply line connected to the LNG fuel tank can be supplied into an internal space of the LNG fuel tank along a recirculation line after the LNG is vaporized.</p> |
