pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.

Boiler Chemistry Control and Treatment of Feed Water .

May 05, 2015· It is necessary to treat the boiler water to produce protective coat on the tubes required for good quality water & steam. For this it is necessary that the water shall be low controlled alkaline, very low level of dissolved Oxygen and very low presence of ions like Cl –. Silica from CW is another damaging factor as it deposits on turbine. Silica needs to be controlled at DM plant also.

The Importance of Boiler Water and Steam Chemist

For most dissolved solids found in boiler water, it is negligible by comparison to mechanical carryover at pressures less than 2000 psig (13.8 MPa). An exception is silica for which vaporous carryover can be substantial at lower pressures. Vaporous carryover depends on pressure and on boiler water chemistry. It is not affected by boiler design.

QUIZ: Boiler Water Treatment Chemical Guidelines — Part

able for boiler water treatment, the tetra sodium salt of ethylenediaminetetraacetic acid (EDTA) is typical of the chelating agents being used today. In addition, it is prob- ably the most widely used chelant available. This complex is sufficiently soluble in the concentrations commonly used in boilers so that it effectively holds the calcium in solution. The reaction with magnesium is the same.

The pretreatment system prepares the raw water (or make-up water) before it goes to the boiler. It could involve several pretreatment steps, all acting to reduce the dissolved and suspended solids from the water. Chemical treatment helps you avoid unwanted impurities. • Lime-soda softening — Precipitation chemicals are added to react with

Water used to generate steam contains various impurities, the most typical being compounds of calcium, magnesium, silica and iron. In an system where impurities are allowed to reach excessive concentrations, steam quality can be impaired. In addition, hardness salts can precipitate from the boiler water to form sludge and eventually scale, which deposits on the internal surfaces of the boiler.
