Its caustic concentration can be as high as 10,000-100,000 ppm. Careful control of boiler water chemistry can prevent caustic gouging. If the "free hydroxide alkalinity" is set too high or uncontrolled, then caustic gouging may result. Prevention of porous deposit formation (such as iron oxide) eliminates a place for caustic gouging to occur.

Considerations for High Pressure Boiler Chemical

2018-8-22 · Considerations for High Pressure Boiler Chemical Treatment – Equipment and boiler pressure range is 1500 to 2000 psig (104 to 140 bar) as this is the typical HP steam range <30 ppb (ųg/l) TDS, < 10 ppb (ųg/l) Na, <20 ppb (ųg/l) SiO2, and it should be essentially oxygen free.

Effects of High TDS Levels in Feed Water to Boiler

If TDS concentration in feed water is maintained at 1000 ppm, steam dryness will reduce to 85% so this will lead to increase blowdown frequency to maintain the TDS levels under desired operating limits and inturn increases heat losses.
