PROBLEM TO BE SOLVED: To provide a drain recovery system capable of measuring the usage of steam in a load device with higher accuracy.SOLUTION: A drain recovery system 16 includes: a flash tank 23; a first pressure sensor 31; a second pressure sensor 32; a third pressure sensor 33; a water level detector 34; a temperature sensor 35; a controller 36; an output part 37; a steam discharge line L21; a drain discharge line L22; a blow drainage line L23; a steam control valve V21; a drain discharge valve V22; and a blow drainage valve V23. The controller 36 obtains an amount of drain 22 discharged from the flash tank 23 and an amount of flash steam 28 and calculates an amount of the drain 22 discharged from a first load device 13 on the basis of the obtained drain amount 22 and the obtained flash steam amount 28 to calculate the steam usage in the first load device 13. The output part 37 displays the steam usage. |
