Abstract

PURPOSE: To easily thaw the frozen portion inside the heating pipe of a multi-pipe type heat exchanger in which a liquefied gas is vaporized by a method in which outlet and inlet nozzles for an outside-pipe fluid are enclosed and a heat medium is passed through a heating pipe for the heat medium.
CONSTITUTION: In case where the inside of a heating pipe 1 is frozen, a control valve 9 is closed and a switch valve 10 is opened. then, a steam pipe is connected to a through pipe 12 and an outside-pipe fluid is heated by steam. The outside-pipe fluid naturally circulates through a connection pipe 11 to heat and thaw the frozen portion of the heating pipe.
