Boiler tube metal corrosion can add to this deposit, but with good boiler operation and proper water treatment practices, tube metal corrosion is not usually significant.

Boiler Water Treatment

For a low pressure boiler, simple soft water may suffice. Therefore, the water treatment technology needed also varies with the type of boilers and with the nature of source water. However, with better water quality, it is easier to operate and maintain the steam–water system with minimum deposition- and corrosion-related problems.

Chapter 10 Boiler Feedwater Deaeration

In order to deaerate the boiler feedwater, water is sprayed into a steam atmosphere. This heats the water to within a few degrees of the temperature of the saturated steam. Because the solubility of oxygen in water is very low under these conditions, 97 to 98% of the oxygen in the incoming water is released to the steam and is purged from the ...
