Provided is a device for vaporizing a liquefied gas, with which, even if a heat source fluid has a low temperature, a liquefied gas intended to be vaporized can be vaporized to produce a produced gas of a predetermined temperature or higher, and it is possible to simplify the configuration and conserve energy. The device for vaporizing a liquefied gas is provided with: an intermediate heat medium vaporizer (10) for exchanging heat between a heat source fluid (SW) and an intermediate heat medium (LPG), and vaporizing the intermediate heat medium (LPG); and a liquefied gas vaporizer (20) to which an intermediate heat medium (PG) vaporized at the intermediate heat medium vaporizer (10) is supplied, and which exchanges heat between the intermediate heat medium (PG) and a liquefied gas (LNG) intended to be vaporized, condenses the intermediate heat medium (PG), and vaporizes the liquefied gas (LNG) intended to be vaporized. The device is configured such that the intermediate heat medium (LPG) is returned from the liquefied gas vaporizer (20) to the intermediate heat medium vaporizer (10), wherein the device is provided with a temperature-raising means (30) for raising the temperature of the intermediate heat medium (PG) that is vaporized at the intermediate heat medium vaporizer (10) and supplied to the liquefied gas vaporizer (20). |
