Boiler Blowdown Tanks Home / General Process Tanks / Boiler Blowdown Tanks Boiler Blowdown Tanks Features Heavy ware plate Built to ASME code Section Viii, Div. 1 1 coat of shop primer Custom sizes available Boiler Blowdown Tanks are an essential part of a steam heating system. As water turns to steam in these systems, small amounts of solids are collected in the boiler as evaporation of steam dissolve impurities from the water and piping. Left untreated, these impurities can reach significant levels and potentially cause damage to the steam boiler. Blowdown tanks accept and retain discharge steam and water from the boiler and remove particles. Over time water collected in the blowdown tank cools, as the next discharge happens, the new discharge forces the cooler water back to the boiler system where the cycle begins again.
