Blowdown Tanks

Blowdown tank or “Blowdown separator” means an ASME-stamped vessel designed to receive discharged steam or hot water from a boiler blowoff or blowdown piping system.Blowing down a boiler refers to the process of removing water from the boiler with any excess bottom sludge and dissolved solids. Companies need to blow down their boilers regularly, since the concentration of dissolved solids from makeup water increase in a boiler after removing pure water as steam.The primary purpose of blowdown is to maintain the solids content of boiler water within certain limits. This may be required for specific reasons, such as contamination of the boiler water. In this case, a high blowdown rate is required to eliminate the contaminants as rapidly as possible.
