•SILICA -- coming thru the makeup water to the feedwater that may be used for attemperation can cause problems in the turbine area. Especially if colloidal silica is present in the makeup water. •Recommend maintaining close limits of allowable silica in the boiler water to keep sat steam silica < …
COLLOIDAL SILICA IN BOILER WATER Liked by Brad Crocker. A few thoughts about #IndustrialWaterWeek. A few thoughts about #IndustrialWaterWeek. Liked by …
Silica Scaling in Boilers. Silica, 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.
Silica: The presence of silica in boiler water can rise to formation of hard silicate scales. It can also associate with calcium and magnesium salts, forming calcium and magnesium silicates of very low thermal conductivity.
Jun 17, 2012 · Good Answer: As 911 posted, confirm your water treatment upstream of the boiler is working correctly, then problem should go away. But are you sure it is Silica Have you had this tested, did the tests show any
Although a demineralizing plant existed for the boiler feed water make up, the ion exchange resins were not able to retain the colloidal silica. Also, the First Unit operation was held at 25% of its rated capacity; in trying to raise the output to 50%, the silica concentration in the boiler water …
Oct 01, 2018 · A colloidal silica slip will significantly increase the SiO2 levels in the boiler water, well above typical values of 2-20 ppm (for pressures > 900 psig).
De mineralised water to be produced for the High Pressure Boilers at Sterlite Industries. Project comprises of handling high reactive silica, colloidal silica and TDS of 7000 mg/L . During the tendering stage to execution phase, Scheme was framed by keeping the stringent inlet and outlet characteristics.
Despite advances in conventional deposit control technologies, high-silica boiler water (>150 mg/L as SiO2) continues to have a major impact on the operation and efficiency of boilers
Mar 31, 2021 · This makes colloidal silica very hydrophilic and capable of forming numerous hydrogen bonds. Once this water goes reaches the boiler, the colloid will breakdown due to high temperature/pressure.
The current DT is incapable of removing colloidal silica from the raw water due to the lack of charge on the colloidal silica molecules. If allowed to enter the boilers, colloidal silica can lead
Boiler system components, and the mechanisms by which deposits form and corrosion occurs, are varied and complex. A complete boiler water treatment program may include: 1. Chemicals to react with feedwater hardness 2. Sludge conditioners to prevent suspended solids from sticking to the boiler metal 3. Oxygen scavengers to prevent corrosion 4.

Apr 30, 2012 · The tight molecular weight cut-off of 10,000 daltons of the membranes offers a colloidal silica removal rate of 99.8%. By efficiently removing the colloidal silica, Pentair X-Flow provides an alternative for silica removal. The high-pressure boilers are protected from scale deposits, which maximizes performance and prevents turbine failure.
Development of technique for online monitoring of colloidal silica in steam water cycle Colloidal silica is difficult to be analysed and causes severe problems in boilers and turbines. NETRA is developing an online method for detection of colloidal silica in DM water so that preventive measures can be taken.
