Blowdown Tanks
A Blowdown Tank is a tank incorporated into a boiler system to safely discharge blowdown. Blowdown refers to boiler water which has an elevated level of dissolved solids. Over time, makeup feedwater is introduced to the boiler to maintain an appropriate water level as water vapor leaves the system through steam leaks, etc. This is the source of additional dissolved solids into the system. These dissolved solids must be periodically removed from the boiler system as they adversely effect efficiency and service life of the boiler. A Blowdown Tank allows the blowdown to be safely brought down to appropriate pressure and temperature before disposal.
