Where blowdown lines connect into an inlet manifold on the vessel, each must be fitted with either a screw down non-return valve or, a non-return valve and an isolating valve. This is to prevent the possibility of steam and pressurised hot water being blown from one working boiler into another (inside which personnel may be working) during maintenance.

Selection of Blowdown Systems - Industrial steam

The Blowdown Separator receives the hot water from the boiler. The separator is sized to operate at 1 -2 psig in order to force the blowdown water to the drain. As the water enters the separator, the pressure of the water drops to the operating pressure of the separator. The excess energy in the water is given up as some of the water flashes to
