Water hardness - Corrosion

Water Hardness. The hardness of a water supply is determined by the content of calcium and magnesium salts. Calcium and magnesium can combine with bicarbonates, sulfates, chlorides, and nitrates to precipitate as solids Mineral salts make water more basic and corrosion aggressive on many materials.

Basics of Marine Engineering: BOILER WATER

Nov 29, 2012 · Prevention of Condensate Loss - Condensate water is very pure and free from hardness causing minerals. Make up water on the other hand has impurities. As learnt before Boiler Feed Water is the sum of make up water and condensate water. So lesser the amount of make up water we add lesser the quantity of impurities being introduced to the system.

The Importance of Boiler Water and Steam Chemistry

Even where steam purity requirements are not imposed by the application, dissolved solids concentrations less than 1.0 ppm are recommended at pressures up to 600 psig (4.1 MPa), less than 0.5 ppm at 600 to 1000 psig (4.1 to 6.9 MPa), and less than 0.1 ppm above 1000 psig (6.9 MPa).

Total Dissolved Solids - TDS

When the concentration of impurities becomes higher, foam is generated and the volume of the boiling water starts to increase. As a result - more and more low quality wet steam will be generated. The concentration of impurities is often termed TDS - Total Dissolved Solids (ppm) and can be measured using a conductivity or density method.
