Answer / santhosh reddy

Due to the alkalinity, as water evaporates in the boiler,
it leads to the deposition of salts and these salts
deposited act as scales and prevent the transfer of heat to
the water in the tubes of the boiler as scales are bad
conductors of heat. This further increases the heat
consumption and the tube heating and thus lead to bending
of tubes due to overheating.

Answer / k.a.a.m

fouling , this is the result of using high alkaline water ,
then the consequence is : over heating the tubes then tube
failure.
