LIQUEFIED NATURAL GAS VAPORIZATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a liquefied natural gas vaporization system recovering waste heat discharged from a dry furnace of an asphalt aggregate using natural gas as burner fuel, and suitable to be effectively utilized as a heat source in a vaporizer of liquefied natural gas.SOLUTION: A liquefied natural gas vaporization system X includes: a vaporizer 2 heating liquefied natural gas with liquid heat medium for vaporization; a dry furnace 3 heating and drying an asphalt aggregate with natural gas vaporized by the vaporizer 2 as fuel; a heat exchanger 4 using exhaust gas, discharged from the dry furnace 3, used in heating of the liquid heat medium; and heat medium lines 63, 64 circulating the liquid heat medium between the heat exchanger 4 and the vaporizer 2.SELECTED DRAWING: Figure 1
