摘要： There is provided a drain recovery system with which power for driving a feedwater pump can be reduced and the feedwater pump can be driven at low costs. The drain recovery system includes: a buffer tank; an assist tank disposed below the buffer tank; a first drain supply line that connects a load device and the buffer tank; a second drain supply line that connects the buffer tank and the assist tank; a drain supply valve; a communication line that establishes communication between the assist tank and the buffer tank; a communication valve; a steam supply line that supplies steam from a boiler to the assist tank; a steam supply valve; a feedwater line that supplies drain from the assist tank to the boiler; and a feedwater pump.

摘要： To achieve a downsized drain tank without reducing an effective drain recovery rate. A closed drain recovery system includes: a steam boiler (2); a closed-type drain tank (4); an air-open-type makeup water tank (7); a steam introduction line (10) for introducing a first flush steam within the drain tank (4) to the makeup water tank (7); a surplus drain introduction line (8) for introducing surplus drain to the makeup water tank (7) from the drain tank (4); and condensing units (33) and (39) provided for the makeup water tank (7), and configured to condense one or both of the first flush steam and a second flush steam by bringing the one or both of the first flush steam and the second flush steam into contact with the makeup water within the makeup water tank (7), the second flush steam being generated from the surplus drain.
