The Importance of Boiler Water and Steam Chemistry

Steam blanketing is a condition that occurs when a steam layer forms between the boiler water and the tube wall. Under this condition, insufficient water reaches the tube surface for efficient heat transfer. The water that does reach the overheated boiler wall is rapidly vaporized, leaving behind a concentrated caustic solution, which is corrosive.

The Importance of Boiler Water and Steam Chemistry. Steam Purity. Purity or chemistry requirements for steam can be as simple as a specified maximum moisture content, or can include maximum concentrations for a variety of chemical species. Often, for low pressure building or process heater steam, only a maximum moisture content is specified.

During the operation of the boiler, the boiler water was analyzed for alkalinity and electrical conductivity. The alkalinity of boiler water for phenolphthalein (A ph) is 20 mg-eq/l, for methyl orange (A mo) is 2.0 mg-eq/l. Total alkalinity is 22.0 mg-eq/l. The boiler water conductivity – 7798 μS/cm.

Water Handbook - Preboiler & Industrial Boiler Corrosion

Jun 24, 2014 · It comes into play with steam boilers because a pH between 7 and 9 (slightly alkaline) is just right. If the pH is lower than that, the water will start eating the pipes. If it's higher than that, the water won't corrode metal, but it may begin to foam, and that's not good. Hold that thought for a moment.

The total alkalinity of boiler water includes all dissolved components that are capable of reacting with acid: These are most commonly hydroxide (OH-), carbonate (CO-2), bicarbonate (HCO-), phosphate (PO-3), and silicate (SiO-2). Among these alkaline components, the hydroxide is most important from a chemical control standpoint; it is measured directly by pH determination or by titration.

Alkali Boil Out of Steam Boilers – Collaton Consultancy

Aug 26, 2013 · Alkalinity in steam-generating boilers is a problem because under heat the alkalinity breaks down to carbon dioxide, which passes with the steam. When the steam becomes condensate, the carbon dioxide becomes carbonic acid, which is corrosive to the steam lines. Water contains alkalinity. The amount depends on the source of the water, be it surface water (lakes and rivers) or groundwater …

The alkalinity of boiler water should be sufficiently high enough to protect shell and plates against acidic corrosion, but not high enough to produce carryover. A minimum value for alkalinity for adequate protection is 200 PPM. High boiler alkalinity, which is in excess of 700 PPM, should be avoided. Values higher than this can lead to

Because of an alkalinity that delivers twice as much CO2 formed from HCO3- by CO32- due to interference of bicarbonate is the sum of reactions above. Carbonic acid is usually neutralized with chemical treatment at each steam directly or indirectly through boiler to produce pH around 8.5 to 9.0. Reduction of alkalinity in the boiler feed water is necessary to minimize the formation of CO2 and …
