Title:
DRAIN RECOVERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/170564
Kind Code:
A1
Abstract:
The purpose of the present invention is to prevent the pressure of a boiler from decreasing when the load on the boiler is high in a drain recovery system including a recovery tank where drain produced in a steam-using device is recovered and supplied to the boiler. This drain recovery system (10) comprises: a recovery tank (21) that stores drain produced by the condensation of steam in a steam-using device (4), and that supplies the stored water to a boiler (2); and a control unit (40) that controls the amount of water supplied from the recovery tank (21) to the boiler (2) such that the level of the stored water in the recovery tank (21) does not drop below a tank reference water level which has been set in advance. When the load on the boiler (2) increases to a predetermined load, the control unit (40) lowers the tank reference water level by a predetermined amount.
