Silica Scaling in Boilers - LenntechSilica, in amounts ranging from less than 1 to over 100 ppm, is found in all natural water supplies.In rain hail and snow, silica content range from 1 to 2.8 ppm. In the analyses of various surface and ground waters, silica content range from 1 to 107 ppm.This refers to soluble silica content and not to the silica that may be present in the suspended matter.Steam Boiler: Silica in Boiler WaterThe deposit of silica in boiler water which occurs is as follow: Analcite (Sodium alumina silicate - Na 2 O.Al 2 O 3.4SiO 2.2H 2 O) is formed as result of the aluminum content in boiler water through feedwater. Aluminum which is usually delivered is aluminum that is used in pre-treatment in which less supervision occurs in its implementation.Prediction of silica carry-over and solubility in steam of The presence of silica in boiler water can rise to formation of hard silicate scales. It can also interact with calcium and magnesium salts, forming calcium and magnesium silicates of very low thermal conductivity.
