Water Handbook - Preboiler & Industrial Boiler Corrosion

In high-purity systems, raw water in-leakage (e.g., condenser leakage) lowers boiler water pH when magnesium hydroxide precipitates, resulting in corrosion, formation of atomic hydrogen, and initiation of hydrogen attack. Coordinated phosphate/pH control can be used to minimize the decrease in boiler water pH that results from condenser leakage.

Boiler Water Tests | Viking Water Technology, Inc.

May 04, 2016 · Boiler pH should be kept between 10.5 and 12.5. Below 10.5, there is insufficient protection from corrosion and hardness compounds are not precipitated in the desired, free-flowing form. Above 12.5 there is the possibility of caustic embrittlement and carryover. Condensate pH should be kept between 8.0 and 8.6.

Understanding alkalinity in steam and cooling systems

High boiler alkalinity increases the pH and therefore can contribute towards foaming in the boiler. This leads to boiler water carryover into the steam causing wet steam which will reduce steam efficiency and may contribute to corrosion of the condensate if the materials of construction do not like high pH…

Inferred pH in Steam Plant Water Chemistry Monitoring

Common boiler water treatment chemicals are sodium hydroxide and sodium phosphate salts. They are used to adjust boiler water pH to reduce corrosion and buffer the water against acid-forming contaminants. Boiler water chemicals by and large remain in the boiler. However, vaporous and mechanical carryover do introduce trace amounts into the steam.
