Boilers are key machinery for any industrial power plant, and the
quality of feed water greatly affects the performance and lifespan of these
equipment. For an industrial plant to operate more efficiently, it is important
for feed water to undergo pre-treatment. Thus, the owner must invest in an
advanced water treatment system capable of purifying water in great volumes and
at speeds capable of keeping up with boiler demand.
Natural water contains various amounts and types of dissolved and
suspended matter. These include dissolved minerals, corrosion byproducts, water
contaminants, and solid sediments. The impurities that cause the most damage to
boilers and turbines are silica, sodium, chlorine, oxygen, iron, and magnesium
scales. Because the medium for heat transfer is water, the rate of impurities
deposit can be extremely high. Accumulation of these elements in a boiler
causes it to operate less efficiently, which may eventually lead to equipment
failure. Reliable purification is needed to avoid untimely shutdown and decline
in productivity.
One advanced purification system, which can be used along with other
pre-treatment equipment, is industrial reverse osmosis (RO). Using pressure to
force water through a special semi-permeable membrane, RO is able to remove a high
percentage of impurities. This helps the plant avoid costly downtime and the
repair or replacement expenses that come with shutdowns. The technology also
promotes longer lifespan not only for the boiler but also for other parts such
as the condenser, the turbines, and the pumps.
