Water Cooled Blowdown System

The Blowdown Separator receives hot water from the boiler. The separator is sized to operate with a boiler and the blowdown water overflows to the drain. As the water enters the separator, the pressure of the water drops to the operating pressure of the separator which is near atmospheric. The excess energy in the water is given up as some of the water flashes to steam. The steam leaves the vessel through the vent & is discharge to a safe location outside of the building.

The blowdown separator will reduce the water temperature to approximately 212F by allowing the steam to flash. The local
environmental codes require that the water temperature be lowered further to 140F before it is discharged to the sewer system. An “aftercooler” is required to mix cooling water with the 212F water to meet this requirement. If the cooling water available is 60F, approximately 1 gallon of cooling water will be required to reduce the temperature of the blowdown water to 140F.

Reimers has many options available for boiler sizes.  Optional water cooling as shown is suggested to meet code.
