LIQUEFIED GAS SUPPLYING DEVICE

PROBLEM TO BE SOLVED: To provide a liquefied gas supplying device suppressing the rise of the concentrations of hydrocarbon content with high boiling point and sulfur content in a gaseous phase liquefied gas. SOLUTION: This liquefied gas supplying device comprises a container 3 storing the liquefied gas, a gas pipe 7 communicating with the gaseous phase part 5 of the container 3, a heater 11 heating the liquefied gas in the container 3, a detection means 9 detecting pressure in the container 3, and a heat medium supply means supplying a heated medium to a heater 11. The heat medium supply means comprises heat medium flow passages 19a, 19b supplying the heated heat medium to the heater 11, a pump 17 circulating the heat medium to the heat medium flow passages 19a, 19b according to a pressure detected by the detection means 9, and a heat exchanger 21 heating the heat medium. The heater 11 comprises a tank 49 having a flow passage formed for the heat medium flowing into the heater from its central portion or its portion along the central axis in the horizontal direction toward at least its edge portion facing that portion. Since convection occurs at a liquid phase part 25 in the container 3, the concentrations of the hydrocarbon with high boiling point and the sulfur in the liquid phase part 25 can be leveled.
