Water impurities and their harmful effects on boiler

Today we discussed  about the water impurities and their harmful effect on the boiler. rain water is the biggest resource for drinking water for the leaving organism

Rainwater is the closest thing to pure water when it starts falling from the cloud. It picks up gaseous impurities mainly oxygen and carbon-di-oxide from the atmosphere and when it falls down to earth picks up impurities from ground. The surface water (river, lake, sea) contains impurities like mud, dirt and turbidity. It also contains dissolved impurities leached from the earth and rocks. Organic matter and color are mainly due to sewage, industrial waste

and decaying vegetation. The underground water may be free from suspended impurities due to filtering action during percolation through earth. Under ground water contains more dissolved impurities – such as calcium and magnesium salts, iron and manganese, leached from the rocks. It has low organic impurities.

Harmful effects of water impurities

Water has the ability to dissolve every naturally occurring substance on the earth to certain degree. Water is therefore known as universal solvent. Water finds universal application as industrial fluid on account of it’s abundance in nature. Presence of impurities limits it’s application and warrants treatment before water can be used in it’s natural state. These impurities if not removed from water can cause.

1) Scales in Boilers and Heat exchangers.

2) Poor quality boiler steam.

3) Corrosion of boilers, heaters and piping.

4) Stains, discoloration, spots.

5) Off flavor and taste in food and drinks.

6) Destruction and waste of various chemicals such as soaps and alkalies

used in washing and dyeing.
