header and the velocity of steam leaving the boiler are, therefore, important elements in boiler design. As the rate of steam production goes up, so does the tendency for steam contamination.The sudden opening of a steam valve or the cutting in of a boiler too quickly speeds up the production of steam, which can cause violent bubbling and carryover.

Boiler problems caused by hard water, How does hard water

Scale and Sludge Formation In industries, steam is used for the generation of electricity. Steam in turn is produced in boilers. When hard water is used for production of steam concentration of dissolved salts increases progressively due to the evaporation of water. When their concentration reaches beyond saturation point, the dissolved salts start precipitating out and get settled on the inner walls of the boiler.

The most common boiler scales are hardness scales made of calcium or magnesium combined with carbonate, phosphate, or silica. Iron can also form scales commonly, and silica can form scales made only of oxygen and silica. Less common is a scale that forms from evaporation to dryness.
