POWER RECOVERY SYSTEM

摘要

A power recovery system is provided which is capable of stabilizing the power recovery rate thereof. The power recovery system 1 includes: a Stirling engine 10 that generates power by supply of cold heat to an upper portion 16a of a cylinder 16; and a vaporization device 20 that stores a liquid therein in such a manner that the liquid is kept in contact with the upper portion 16a of the cylinder 16 and vaporizes the liquid by supplying the cold heat of the liquid to the upper portion 16a of the cylinder 16. The vaporization device 20 includes a liquid container 21 which stores the liquid therein in such a manner that the liquid is kept in contact with the upper portion 16a of the cylinder 16, and an outer container 22 embracing the liquid container 21 and defining a space portion 30 around the liquid container 21. The space portion 30 communicates with the liquid container 21 and an exhaust vent 22a. Gas vaporized in the liquid container 21 passes between the liquid container 21 and an outer wall surface 23 a of a heat insulating material 23 during passage thereof from the liquid container 21 to the exhaust vent 22a through the space portion 30.
