VAPORIZATION METHOD AND VAPORIZATION APPARATUS USED FOR VAPORIZATION METHOD, AND VAPORIZATION SYSTEM PROVIDED WITH VAPORIZATION APPARATUS

摘要

Disclosed is a vaporization method comprised of a preparatory process for preparing a vaporization tube which covers at least a part of a heat exchange unit for cold energy of a Stirring engine and which can form an upward flow of liquid from the bottom to the top of the heat exchange unit for cold energy; and a vaporization process for forming an upward flow by flowing liquid within the vaporization tube, to bring the liquid into contact with the Stirring engine to vaporize the liquid. In the preparatory process, the direction of the upward flow is adjusted to suppress occurrence of separated flows of liquid and gas within the vaporization tube. In the vaporization process, the liquid flows at a flow rate at which a gas-liquid two-phase flow wherein liquid and gas are mixed, is formed within the vaporization tube.
