Blowdown Separators for Boilers

The purpose of blowdown separators for boilers is to cool off the intermittent boiler blowdown flow so the waste water can be safely discharged into a public sewer system and so that the flash steam can be safely vented into the atmosphere. All Madden boiler blowdown separators are pressure vessels made to ASME Section VIII, Divison 1 standards.

Function

High temperature and high pressure blowdown water impacts the striking plate instide the separator. Flash steam is created and the remaining 212°F hot water drains into the aftercooler. The Flash steam exits to the atmosphere through the vent connection. In the aftercooler the hot water is mixed with cooling water to instantaneously cool the blowdown to a safe temperature. A baffle is placed to assist the mixing of the two liquids. Both the blowdown and cooling water are then sent off to the public sewer.
