Why the silica concentration in a boiler drum increase

The primary concern is avoiding silica/silicate-based deposits which are thermally insulating and significantly reduce heat transfer. Conventional treatment requires limitations on boiler silica

An ever-increasing number of us had co me to use oil for household heat, and even some electrically heated homes were, at the power plant, dependent on oil-fired boilers to supply steam to spin the big generators. The prospect of having no fuel to supply heat was frightenin,g indeed.

silica found in the boiler. Should the concentration of silica in the drum become too high, then a 'blowdown' is initiated. This is the removal of contaminated water from the boiler. Adequate control of the blowdown is very important. If it is allowed to occur too often, it becomes expensive and inefficient. The silica monitoring in the boiler drum is one parameter which can be used to control blowdown. 0 and ! – Steam

Steam Boiler: Silica in Boiler Water

Little aluminum content in feedwater can cause high deposit of silica in boiler water. Therefore feedwater treatment must be controlled to eliminate aluminum and silica. Acmite (Sodium Ferrous Silica - Na2Fe2O3 4SiO2) and crust Fe - Si can be formed from corrosion result.

High-Pressure Steam Cycle and Boiler Water Treatment

The vaporous silica carryover at a pH of 11.0 is 74% of that at 8.8. The only effective method for preventing excessive silica or other vaporous carryover is reduction of the boiler water concentrations. Another common source of excessive impurities in steam is inadequate attemperation spray water purity.

Silica Scaling in Boilers - Lenntech

This can be gained through external treatment equipment for make up water or monitorning and controlling the condensate contmination. After silica enters the boiler water, the usual corrective action is to increase boiler blowdown and then to correct the condition that caused the silica contamination.
