PROBLEM TO BE SOLVED: To provide a drain recovery system capable of saving space even when a storable amount of drain is increased.SOLUTION: A closed type drain recovery system 1 recovers and feeds to a boiler 111 drain in a high-temperature and high-pressure state produced by condensing steam generated in the boiler 111 and used in a load device 130. The drain recovery system 1 comprises: an upper side drain tank 10 formed in a cylindrical shape and arranged in such a manner that a height direction is parallel to a horizontal direction; a lower side drain tank 20 formed in a cylindrical shape and arranged below the upper side drain tank 10 in such a manner that a height direction is parallel to a vertical direction; and a first connection part 30 which connects the lower part of the upper side drain tank 10 to the upper part of the lower side drain tank 20. |
