The Importance of Boiler Water and Steam Chemistry

Excessive steam impurity concentrations can also be caused by feedwater and boiler water chemistries that favor volatile species formation. Carryover of volatile silica can be problematic at pressures above 1000 psig (6.9 MPa). Vaporous silica carryover at a pH of 10.0 is 88% of that at a pH of 8.8.

However EDTA in excess of that required for contaminant chelation can decompose in the boiler water and large excesses of EDTA and NTA can react with the magnetite (Fe 3 O 4) film protecting the boiler. Other anions present in the boiler water (e.g. phosphate silicate and hydroxide) tend to compete with chelants limiting their effectiveness.

Feed water treatment

Sea water leaks result in progressive contamination of boiler water because of the increasing concentration of salts in the boiler due to the residue of evaporation. Furthermore even then boiler feed water is within its allowed limits of impurities the concentration of salts within the boiler increases in proportion to the rate of evaporation (steaming rate) of the boiler.
