HOT WATER TYPE LIQUEFIED GAS VAPORIZER

摘要

PROBLEM TO BE SOLVED: To provide a hot water type vaporizer in which change of an outlet gas composition hardly occurs at restart time. ! SOLUTION: A hot water type liquefied gas vaporizer includes: a shell body 10 installed in a vertically long manner; a tube 11 having a plurality of reversed U-shaped curve parts 11A which are arranged in the shell body 10, and a pair of straight line parts 11B along the shell body 10; a hot water inflow part 12 which is arranged below the shell body 10 and which communicates with one of open ends of the pair of straight line parts 11B; a hot water outflow part 13 which is arranged below the shell body 10 and which communicates with the other open end of the pair of straight line parts 11B; a liquid inflow part 15 which allows a liquid of a liquefied gas to flow into the shell body 10; and a gas outflow part 16 which allows a gas vaporized in the shell body 10 to flow out. A curvature radius of the curved part 11A is set in such a manner that, when hot water flows in the
