Sri Lankan & Singapore Scientist have found proper solution, for the barnacle issue  of  the Norochcholai  coal power plant

 

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.
