Effect Of Conductivity In Boiler Water

Effect of chloride and sulfate ions in simulated boiler

The pitting corrosion behavior of 13Cr steel was investigated in simulated boiler waters containing chloride ions (Cl −) and sulfate ions (SO 4 2−) 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. Pit initiation was inhibited by the addition of 50 ppm or 100

Boiler water treatment - Lenntech

Chemical treatment of water inside the boiler is usually essential and complements external treatment by taking care of any impurities entering the boiler with the feed water (hardness, oxygen, silica, etc.). In many cases external treatment of the water supply is not necessary and the water can be treated only by internal methods. Internal

The Electrical Conductivity of Water

While the electrical conductivity is a good indicator of the total salinity, it still does not provide any information about the ion composition in the water. The same electrical conductivity values can be measured in low quality water (e.g. water rich with Sodium, Boron and Fluorides) as well as in high quality irrigation water (e.g
