What is calgon conditioning why it is used?

– Addition of calgon to boiler water to prevent sludge & limescale formation is called calgon conditioning. – This prevents damage to heating element, pipes & drums of washing machine. – At higher temperature, calgon converts calcium salts into soluble complexes so they are easily removed.

What is calgon conditioning in Engineering Chemistry?

Engineering Chemistry Questions and Answers – Calgon Conditioning. Explanation: Calgon converts the scale forming impurity like CaSO4 into soluble complex compound which are harmless to boiler.

What is used for calgon conditioning?

Calgon conditioning: Calgon = sodium hexa meta phosphate The process involves the addition of calgon to boiler water.

How does colloidal conditioning work?

In chemistry, a colloidal conditioning is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. To qualify as a colloid, the mixture must be one that does not settle or would take a very long time to settle appreciably.

What is calgon conditioning How is it better than phosphate conditioning?

In calgon Conditioning, the added calgon forms soluble complex compound with CaSo4, thereby it prevents the scale and sludge formation in water. this soluble complex does not cause any problem in boilers. 2Na₃PO4 + 3 CaSO4 —> Ca₃(PO4)₂↓ + 3 Na2 SO4. Hence calgon conditioning is better than phosphate conditioning.

Is calgon conditioning applicable to low or high pressure boilers or both?

c) Calgon conditioning: Calgon is the trade name of sodium hexa meta phosphate- Na2 [ Na4 (PO3)6]. With calcium ions it forms a soluble complex and prevents scale and sludge formation. It is used for high and low pressure boilers.

What is calgon conditioning Slideshare?

Internal Treatment: 4) Calgon Conditioning :  It involves the addition of calgon or sodium hexametaphosphate to boiler water.  This substance reacts with calcium ions and forms highly soluble complex and thus prevents the precipitation of scale forming salt.

What are scales and sludges?

If the precipitation takes place in the form of loose and slimy precipitate, it is called sludge. On the other hand, if the precipitated matter forms a hard, adhering crust/coating on the inner walls of the boiler, it is called scale.

What is calgon conditioning example?

Calgon conditioning: It is the process of addition of calgon or sodium hexametaphosphate to boiler feed water. The calcium ions (responsible for scale / sludge formation) are complexed by calgon to form a soluble complex and hence prevented from their scale forming action.

Why is calgon treatment better than phosphate conditioning?

In calgon Conditioning, the added calgon forms soluble complex compound with CaSo4, thereby it prevents the scale and sludge formation in water. 2Na₃PO4 + 3 CaSO4 —> Ca₃(PO4)₂↓ + 3 Na2 SO4. Hence calgon conditioning is better than phosphate conditioning.

What is internal conditioning?

Internal Treatment (Internal Conditioning) of Boiler Water. Internal treatment involves the addition of chemicals directly to the water in the boilers for removing scale forming substances which were not completely removed in the external treatment. The chemicals added for this purpose are called Boiler compounds.

What is priming and foaming?

Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. Priming may be caused by improper construction of boiler, excessive ratings, or sudden fluctuations in steam demand.

How does Calgon conditioning work in boiler water?

Calgon conditioning involves the addition of Calgon or sodium hexametaphosphate to boiler water. this substance interacts with calcium ions forming a highly soluble complex and thus prevents the precipitation of scale-forming salt – Sodium metaphosphate is called calgon.

What kind of product is Calgon bath softener?

Calgon is a brand registered trademark of water softener, and bath and beauty products.

What was the original use of Calgon for?

Originally promoted for general use in bathing and cleaning, it gave rise to derivative products which have diverged from the original composition.

What was the original product of Calgon soap?

The original product consisted of powdered sodium hexametaphosphate (amorphous sodium polyphosphate), which in water would complex with ambient calcium ion and certain other cations, preventing formation of unwanted salts and interference by those cations with the actions of soap or other detergents.
