What is hard water how it can be softened before using in boiler?
because hard water contains dissolved salts of magnesium and calcium.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. In due course this layer renders the. boilers useless. so it is softened before boiling .
What is the purpose of softening water?
Advantages of home water softening Prevents build-up of minerals (scale) on the inside of pipes, fixtures, and hot water heaters. Lengthens the life of some appliances. Reduces or prevents mineral spots on glassware. Prevents or reduces soap films and detergent curds in sinks, bathtubs, and washing machines.
What is the effect of hard water on boiler?
The minerals in the hard water can lead to scale building up within your boiler. You may notice that you hear a rumbling sound coming from your boiler. This could be the result of scale building up within the burner, and the water boiling to a rapid bubbling state.
How do I control the hardness of my boiler water?
Phosphates-dispersants, polyphosphates-dispersants (softening chemicals): reacting with the alkalinity of boiler water, these products neutralize the hardness of water by forming tricalcium phosphate, and insoluble compound that can be disposed and blow down on a continuous basis or periodically through the bottom of …
Which type of water is suitable for boiler?
The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water). The make-up water is usually natural water either in its raw state, or treated by some process before use.
How do I control the pH in my boiler water?
Controlling pH pH is controlled by either removing water impurities or adding other chemicals to neutralize the condition. For example, Caustic Soda, an alkaline, is added to neutralize CO3, carbonic acid.
Why do you need a water softener in a boiler?
To avoid scaling, boiler water should be circulated through a water softener before it is fed to the boiler. A water softener removes hard water minerals, like calcium and magnesium, which can cause scaling and damage in the boiler tubes. Acting as an insulator, scale deposits can prevent proper heat transfer,…
How does intermittent softening work in a boiler?
The older method of intermittent softening consists of mixing the chemicals with the water in a tank, allowing time for reaction and forming of sludge, and filtering and drawing off the clear water.
What causes a water softener to go bad?
You hear it first on The Nationwide Boiler Blog! The Water Softener: What, Why, and How? One of the leading causes of poor boiler performance is improper water treatment. Improper water treatment, or not treating your boiler water at all, can cause irreversible boiler tube damage called scaling.
Why is hard water not used in boilers?
One of the leading causes of poor boiler performance is improper water treatment. Improper water treatment, or not treating your boiler water at all, can cause irreversible boiler tube damage called scaling. To avoid scaling, boiler water should be circulated through a water softener before it is fed to the boiler.

Can a softner cause Excellerated corrosion in a boiler?
If you are dealing with a closed loop heating boiler a softner can cause excellerated corrosion. If your make-up water has a high concentration of CaCo3 (calcium carbonate) above 100ppm then the prudent thing to use would be DI water or distilled water to fill the system.

How does hard water affect the efficiency of a boiler?
The efficiency of a boiler can also be negatively affected by hard water. If the presence of calcium and magnesium causes hard scaling, it will have an impact on the heat transfer inside the boiler. A layer of hard scaling as small as 1/8 of an inch on boiler tubes can decrease efficiency as much as 25 percent.
