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.
