PROBLEM TO BE SOLVED: To provide a vaporization device for liquid gas which can vaporize vaporization target liquid gas to produce product gas having a prescribed temperature or higher even when the temperature of heat source fluid is low and furthermore can be downsized, simplified in structure, and can be energy-saved.SOLUTION: A vaporization device for liquid gas comprises: an intermediate heat medium vaporizer 10 for vaporizing intermediate heat medium LPG by exchanging heat between heat source fluid SW and intermediate heat medium LPG; and a liquid gas vaporizer 20 which is supplied with the intermediate heat medium PG vaporized in the intermediate heat medium vaporizer 10, exchanges heat between the intermediate heat medium PG and the vaporization target liquid gas LNG to condensate the intermediate heat medium PG while vaporizing the vaporization target liquid gas LNG, and the vaporization device for liquid gas is configured to return the intermediate heat medium LPG to the intermediate heat medium vaporizer 10 from the liquid gas vaporizer 20, and further comprises temperature rising means 30 for rising the temperature of the intermediate heat medium PG which is vaporized in the intermediate heat medium vaporizer 10 and is supplied to the liquid gas vaporizer 20.SELECTED DRAWING: Figure 1 |
