  • Boiler System - Bond Water Technologies, Inc.

    While sulfite and bisulfite increase boiler water total dissolved solids (TDS) content, increasing blowdown demand, DEHA does not add solids to the boiler water. In addition, DEHA is volatile, so the excess over that needed for oxygen removal in the boiler carries off with the steam and is available to prevent oxygen corrosion in the condensate Learn More

  • Water softener use for a steam boiler - good idea

    Mar 21, 2012 · However, as has been said, water softeners work by swapping sodium (salt) for calcium (hardness). Softened water, then is more corrosive than unsoftened water. Treated (NOT softened) water is required for power boilers, or boilers where there is a consumptive use of steam, such as ships and steam locomotives.Learn More

    If the boiler is over cycled, treatment chemicals are overfeed, or alkalinity is too high, carryover may occur. Fluctuating boiler water levels can be a cause too. Boiler carryover is just as likely to have a mechanical cause as it is a chemical cause. Mechanical carryover causes include: Excessive movement of water in the steam drum.Learn More

  • Boiler Water Quality

    Always use a softener to ensure good Boiler Water Quality. Chemicals are designed to polish away small amounts of hardness that by-passes the softener. Silica in boiler feedwater can be a problem in larger steam boiler systems. You must maintain a Total OH alkalinity ratio of 3:1 in high pressure boilers to prevent plating of silica.Learn More
