    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. For further information check our web page about silica scaling in boilers.

    The conditions under which vapour silica carryover occurs have been investigated and documented. It has been demonstrated that for any given set of boiler conditions using demineralized or evaporated quality make up water, silica is distributed between the boiler water and the stream in a definite ratio.
