Boiler Water Treatment - Hartford Steam Boiler Inspection

water softener. In a water softener, boiler makeup water flows through a bed of resin beads that have high sodium (salt) content. This bed is also called a cation exchange bed. The sodium in the exchange bed replaces the calcium and magnesium in the water. This leaves higher sodium content in the boiler water. Sodium stays in solution at high

Boiler Blowdown

As mentioned earlier, insufficient blowdown may cause carryover of boiler water into the steam or the formation of deposits on boiler tubes. Excessive blowdown wastes energy, water and treatment chemicals. The blowdown amount required is a function of boiler type, steam pressure, chemical treatment program, and feedwater quality.
