Boiler Maintenance and Boiler Service Tips
Silica in boiler feedwater can also cause hard dense scale with a high resistance to heat transfer. Alkalinity is a measure of the capacity of water to neutralize strong acid. In natural waters, the capacity is attributable to bases, such as bicarbonates, carbonates, and hydroxides; as well as silicates, borates, ammonia, phosphates, and organic bases.

REMOVAL OF SILICA | Water Treatment | Waste Water …
In high-pressure boilers, the amount of silica must be kept very low, since silica dissolves even in steam, thereby the silica going along with the steam deposits on turbine blades, nozzles, etc. At about 40 kg/cm steam pressure, about 5 ppm of silica dissolves in steam and goes along with it.

How To Clean Scale From Your Boiler - Chardon Labs
Continue turning on and off the boiler to maintain the temperature in the range of 100-130F. Check pH every 15 minutes; (should be 1 or 2). If higher, add Scalzo to depress the pH back to 1-2 pH. Continue step 5 until pH remains at 1 or 2 for 120 minutes or more, depending on scale build-up. The system is then as clean as will be with the
