Hard water is not used in boilers?

Hard water is not used in boilers?

Answer:

Hard water is water that has a high mineral content (water with a low mineral content is known as soft water). This content usually consists of high levels of metal ions, mainly calcium (Ca) and magnesium (Mg) in the form of carbonates, but may include several other metals as well as bicarbonates and sulfates. While it is not generally dangerous to safety or health, it does generally cause potentially costly nuisance problems in the home and in industry. On the other hand, hard water is considered to be ideal for brewing certain styles of beer. Kentucky's distinctive Bourbon whiskey owes its flavor in part to the high calcium content of its groundwater (compared to the pilsener style of beer, the brewing of which requires very soft water). Some hard water chemicals, particularly silicates and calcium carbonate, are also effective corrosion inhibitors, and can prevent damage to pipes or contamination by potentially toxic corrosion products. The simplest way to determine if water is hard or soft is the lather/froth test. If the water is very soft, soap will tend to lather up easily when agitated, whereas with hard water it will not. Toothpaste will also not froth well in hard water. More exact methods of hardness detection use a wet titration method to determine hardness. For many uses, including drinking (aside from the taste), it does not matter whether water is hard or soft. For instance, to put out fires, water a lawn, or wash the mud off the streets, water would have to be very hard to cause a problem. But for bathing, washing dishes and clothes, shaving, washing a car and many other uses of water, hard water is not as efficient or convenient as soft water. Hard water can cause limescale deposits in kettles, washing machines and pipes.
because it forms layer of scale as it contain calcium carbonates .. and that can cos overheating inside the boilers
Hard water is not used in boiler is false. LOL
hard water contains considerable amount of dissolved corbonates of magnesium Calcium in room temperature. When they are boiled inside boilers the decomposed calcium magnesium corbonates (solids) blocks the pipe lines inside them which leads the presure inside the boiler to increase rapidly without control. This will cause the boilers to explode... This blocking inside the pipes doesnot suddnly happen in a day or two... It happens very slowly. But even if it happens slowly its quite a messy a very expensive task to clean them regularly... Therefore hard water isnot used inside boilers...
1)Hard water Contains dissolved salts of calcium and magnesium. 2) When such water is heated in boilers it decomposes and a hard layer of calcium and magnesium carbonate is deposited at the bottom of boilers. 3)In due course this layer renders the boilers useless.
