Sri
Lankan & Singapore Scientists have
found proper solution, for the barnacle issue
of the Norochcholeii coal power plant. They have introduce
Ultra-low frequency which was the core
technology developed by “Ecospec” (http://www.ecospec.com/)
research & development team in
Singapore. Senior research scientist who Lalindra(SL), Aravinda(SL), Sathyajith(SL),
Louis(Sin),Chew(Sin) has develop the new applicable system for barnacle issue, which was directly effect to the cooling
process of norochcholeii coal power
plant & they ‘ll make a huge
profitable out put for electrical generating process of coal plant. According
to the payback calculation, this process will make to save more than 25 million USD for Sri Lankan economy .
Puttalam Coal Power Plant named after the location where
it is located in the Puttalam District of the Northwestern Province in
Sri-Lanka. An important national asset as symbolically it is not only the very
first coal fired power plant in Sri-Lanka but also the largest in terms of
capacity with a total output of 900MW that incorporated and operational as early
as in 2010.
Among which cooling or
condenser water is paramount importance in part of the power generation
process. Strategically power plants are commonly located by the sea or coastal
area to take advantage of the abundant of seawater source as cooling water.
Puttalam power plant is no exception and it is taking huge amount of seawater
to cater for the cooling purpose considering its scale. To achieve this,
purposely built seawater transferring channel is required and in the context of
Puttalam Power Plant, seawater is transferred via concrete culverts measuring
3m x 3m and run approximately 400m long before it reaches the pump house. There
are 3 separate culverts serving each power station.
However, whenever seawater is involved biological fouling can
happen inevitably and this implies that separate fouling control mechanism has
to be in placed along the seawater intake channel to prevent the growth of
marine organisms that could potentially disrupt the power generation process.
Commonly the disruption arises due to constricted flow when the channel is
fouled hence reduce the net cross-sectional area of flow transferring channel
or worse it can lead to the choking of condenser heat exchanger tubes when
there is a lapse in fouling control attributed to ineffective treatment. At
times, biofouling can lead to more complex issue like under deposit corrosion
which can cause leakages of process flow and exacerbate the condition further.
Consequently, this may even lead to abrupt plant shut down that could have
detrimental effect to the macro-economy but also the associated cost of
maintaining and restoring to working condition can be exorbitant.
In view of the occurrences of bio-fouling and its severity it
might be, Puttalam Coal Power Plant is therefore seeking a more cost effective
solution that is not only effective and consistent in controlling bio-fouling
but also environmentally friendly to address the bio-fouling issue to their
seawater intake channel made of concrete culverts. To meet this objectives,
proprietary BioMag system encompasses the ultra low frequency
electromagnetic wave technology is being proposed.
