Jun 24, 2014 · It comes into play with steam boilers because a pH between 7 and 9 (slightly alkaline) is just right. If the pH is lower than that, the water will start eating the pipes. If it's higher than that, the water won't corrode metal, but it may begin to foam, and that's not good.

The Importance of Boiler Water and Steam Chemistry

The safe pH range for steam boilers is between 8.5pH & 12.7pH, whilst the recommended level is between 10.5pH & 12.0pH. Boiler water with a pH of 10.5 contributes 12.6mg/l towards the boiler TDS, whilst at a pH of 12.0 it increases to 400mg/l and at 12.5pH the value is 1264.9 mg/l a 100 fold increase.

Boiler pH. Natural water is usually between 6.5 and 7.5 pH. A common recommendation is to maintain boiler water at 8.5 pH. Acidic water is corrosive. Alkalinic water is more prone to scaling.

Ph And Phosphate Concentration In Bfw And Steam Drum

Steam Chemistry Target Values •Silica –normal saturated steam should be < 20 ppb in most boilers. High pH in the boiler water will reduce silica carryover from the boiler water. Monitor the steam because: •Precipitation of silica forms silicate deposits on the cold end of the turbine that are not water soluble and are very difficult to remove.

What will happen if pH value increases in a boiler? - Quora

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.
