The energy radiations emitted by these salts prevent scale formation. (viii) Complex metric method involves addition of 1.5 % alkaline (pH = 8.5) solution of EDTA to feed-water. The EDTA binds to the scale-forming cations to form stable and soluble complex. As a result, the sludge and scale formation in boiler is prevented.

Chemistry Assignment Help, Scale formation and sludge formation in boilers, Q. Explain scale formation and sludge formation in boilers. How are they formed? Ans Boilers are used for steam generation. When hard water is evaporated, progressively the concentration of dissolved salt is increased. When their saturati

Difference between scale and sludge in boilers? On the other hand if the inner walls of the boiler is not made up of such non sticking material then the salts would stick on them resulting a formation of a thick layer of salts on the walls, this is known as What is the difference between steam boiler and hot water boiler?

Hard Scale(Scale) - Forms in steam boiler -Has the appearance of a white and brown concentration -smooth texture Soft Scale(Sludge) -Forms in the hot water heaters -Appears as a thick ,brown or ...

As a good operator of Boiler we should know the causes for Boiler Scale formation .In this article we can see the scale formation in boilers it gives you a clear idea how to avoid it . The scale formation is one of the major problem in Boiler which effect the heat transfer in boiler.

As of now, we are clear that in every boiler, scale/deposit formation is going to take place. As we cannot bear the losses mentioned above, it is necessary that these scales and deposits are either prevented from being formed and also boilers are regularly monitored for their levels and cleaned when the layers are formed. ... Sludge is normally ...

Water contain minerals in oxide form. These salts at higher steam temperature stick to boiler tubes from inside. This is scaling. Further they keep depositing and keep reducing flow area. Salts mainly get deposited in curved tubes. So water used i...
