boiler softened water containing chloride ion

Boiler Feedwater Treatment (Part I): Why Water Treatment ...

The feedwater (make-up water) from outside needs to be treated for the reduction or removal of impurities by first filtration and then followed by softening evaporation deariation ion exchange etc. Internal treatment is also required for the conditioning of impurities within the boiler system to control corrosion as reactions occur in the ...

Boiler Water Treatment - An overview - MarinersPoint

Apr 29 2020 · Answer: The water enters the boiler from the cascade tank will evaporate .Produced steam is very fine and will contain so chloride as it is heavier .So the chloride will remain in the water drum. As more feed water will enter the boiler the chlorides will be added .This process is continuous and if the chlorine id not blown down regularly it will go beyond limit though using distilled water.

Therefore to give new sodium ions to the Resin the cheapest and easiest means would be to pass the solution of Sodium chloride (common-salt) through the Resin. The same resin can be used over and over again to produce the soft water a- periodic dosage of Sodium chloride (common salt) solution.

Effect of chloride and sulfate ions in simulated boiler ...

Jul 01 2015 · Abstract The pitting corrosion behavior of 13Cr steel was investigated in simulated boiler waters containing chloride ions (Cl ) and sulfate ions (SO 42) using potentiodynamic and potentiostatic polarization tests in addition to pit morphology analysis. The presence of 100 ppm Cl in the water caused pitting corrosion of the steel.

Boiler fill-soft or hard water Heating Help: The Wall

Mar 28 2021 · Absolutely do not use water softened with ion exchange softeners. Yes the hardness minerals are stripped out. But it is "ion exchange" -- and the exchanged cation is sodium. Some but by no means all of the chloride is rinsed -- but there is as much chloride left as there is sodium added. So basically ion exchange softened water is dilute seawater.

Water for the Boiler | Spirax Sarco

This is the simplest form of ion exchange and also the most widely used. The resin bed is initially activated (charged) by passing a 7 - 12% solution of brine (sodium chloride or common salt) through it which leaves the resin rich in sodium ions. Thereafter the water to be softened is pumped through the resin bed and ion exchange occurs.

Water Handbook - Boiler Blowdown Control | SUEZ

In plants with sodium zeolite softened makeup water the percentage is commonly determined by means of a chloride test. In higher-pressure boilers a soluble inert material may be added to the boiler water as a tracer to determine the percentage of blowdown.
