Question

When boilers are used for very long time then white layers get deposited on inside of these boilers what is the cause and remedy?

Answer 1

The white layer is fluorine that is present in water.It shows the pureness of the water. If it is less than water is pure and vuce-versa

Answer 2

Boilers are actually large metal containers which are generally used to boil large amount of water in an industrial scale.

During the prolonged usage of these boilers,a white layer gets deposited in the internal surface of that particular boiler.

This white layer is nothing but a layer of fluorine which is an impurity of the water.

To clean is layer we can simply use some cleaning acids which will dissolve and clean this flourine layer in the boiler.
