Abstract:
1. A power recovery system comprising: a Stirling engine having a hot heat exchanging portion and a cold heat exchanging portion and generating power by supply of hot heat to the hot heat exchanging portion and supply of cold heat to the cold heat exchanging portion; and a vaporization device including a liquid storage portion which stores therein a liquid having cold heat in such a manner that the liquid is kept in contact with the cold heat exchanging portion, an outer member which embraces the liquid storage portion and defines a peripheral space portion around the liquid storage portion, and an exhaust portion which is located at a position away from the liquid storage portion and exhausts gas vaporized in the liquid storage portion from the outer member, the vaporization device being configured to vaporize the liquid by supplying the cold heat of the liquid to the cold heat exchanging portion, wherein the peripheral space portion communicates with the liquid storage portion and the exhaust portion to allow the gas vaporized in the liquid storage portion to pass between the liquid storage portion and an outer wall surface of the outer member during passage thereof from the liquid storage portion to the exhaust portion, and the peripheral space portion includes a region formed between an inner surface of the liquid storage portion and the outer wall surface of the outer member, and between a top level of the liquid stored in the liquid storage portion and a bottom level of the liquid stored in the liquid storage portion.
