Scaling in boilers - Lenntech

This ratio depends on two factors: boiler pressure and boiler water pH. The value of the ratio increases almost logarithmically with increasing pressure and decreases with increasing pH. If the silica enters the boiler water, the usual corrective action is to increase boiler blowdown, to decrease it to acceptable levels and then to correct the condition that caused the silica contamination.

The blow down is used to remove dissolved and undissolved solids that build-up over time in the boiler when it is used. The blow down water can be put through a heat exchanger to warm the incoming feed water and then sent for treatment to neutralise the highly alkaline chemical content (pH 10+) back to pH 6 – 8 before discharging it in a contained evaporation pond.
