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.

Boiler feedwater - Wikipedia

2019-7-28 · Boiler feedwater treatment. Boiler water treatment is used to control alkalinity, prevent scaling, correct pH, and to control conductivity. The boiler water needs to be alkaline and not acidic, so that it does not ruin the tubes. There can be too much conductivity in the feed water when there are too many dissolved solids.

Boiler Carryover – Cause, Effect and Prevention

In low/medium pressure boilers (<100 bar) entrained boiler water is the most common cause of steam contamination. Both mechanical factors such as boiler design, high water levels, load characteristics and chemical factors such as high solids concentration, excessive alkalinity, presence of contaminants contribute to the creation of carryover.

Foaming and priming in boilers - Lenntech

Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain types of
