SUBJECT: Steam Boiler Water Treatment

If chemical treatment is not used, drain and refill the boiler when the chloride level is above 400 ppm, or the total dissolved solids (TDS) are above 1000 ppm. After refilling the boiler, bring the boiler to pressure for 15 minutes per the boiler manual to drive off excess oxygen.

Guide to Steam Systems Part 1 Steam Generation

As steam is evaporated the concentration of total dissolved solids (TDS) increases in the boiler water. If the TDS concentration is allowed to get too high then carryover of boiler water will occur. This carryover can cause serious damage to the steam and condensate systems through corrosion and deposition on heat transfer surfaces.
