Refurbishing a Sea Water Corroded Hammerhead Filter: Possible or Not?
The power generation industry has come a long way since Thomas Edison introduced power stations to the UK in 1882.
We no longer rely exclusively on coal to generate energy. Instead, we can draw electricity from a variety of different sources, including hydraulics, wind power, and even the sun. However, while many of the resources that human beings can use to generate power are evolving, there are parts of the power plant that must always be preserved, such as a reliable filtration system. Unlike coal and steam-powered mechanisms, filters arent a facet of manufacturings past. While many of the filters that we use today are more advanced and efficient, filtration still places a crucial role in the efficient running of plants, both traditional and modern. Like any aspect of machinery, filters require maintenance and care to ensure that they can continue delivering the performance that power stations need. So, how can power plants preserve their filters? Thats where Croft comes in.
Power Stations and Water Cooling
Preserving the longevity of a power station requires extensive planning and strategy. Aside from creating the power that we need to run our homes and cities, these stations also produce a lot of excess energy over time, often in the form of noise and heat. When mechanical components are regularly exposed to continuous heat, they quickly begin to break down, disrupting the entire plant. To eliminate this issue, power generation companies need a dependable way to keep machinery cool. One of the most common options is water. While many power stations today utilise freshwater and wastewater for cooling purposes, salt water has also been a face of power plant production for many years. The ocean covers more than 70% of the planet, making seawater an abundant resource. For coastal power plants, like the now decommissioned Deeside Power Station, saltwater can be an obvious choice.
Tackling the Challenge of Sea Water Corrosion
While sea water cooling provides many benefits, including easy access, the salt in the water also corrodes the metal used in filtration and mechanical systems much faster than fresh water. Salt adds a mild abrasive to the water cooling process, which accelerates damage. Additionally, filters placed in the sea are also exposed to various elements of sea life, including crustaceans. Several years ago, Croft Filters was approached by the Deeside Power Station to repair their hammerhead filter. Exposure to seawater had utterly corroded the system and left it covered in debris and barnacles. Despite the dire condition of the hammerhead filter, our experienced team of refurbishment experts was able to remove much of the corrosion, through a multi-step process. We began by removing the barnacles from the filter, we then repaired the main body of the filter, and replaced various components with copper-nickel to reduce future risk of corrosion. In cases where refurbishment isnt an option following seawater corrosion, Croft Filters can still offer expert support to power stations. We take great pride in our ability to Thermoelectric power plants, for instance, boil water to create steam. The steam then spins turbines, which generates electricity. Once steam passes through the turbine, it needs to be cooled again to move back into the machinery as water. Thermoelectric plants close to the coast may experience a similar problem to Deeside, with corrosion. Alternatively, the Dinorwig Power Station, known to locals as Electric Mountain, uses a pumped-storage hydroelectric strategy to generate power. Water is stored at a high altitude in a reservoir and discharged through turbines during times of peak demand to keep the machinery cool. Even a station like this that dont need to worry about saltwater corrosion will still require ongoing maintenance of their filtration system. No matter the kind of power station, or the cooling methods it uses, filters will always be a crucial component of the industry. The right, well-maintained filters support excellent ongoing performance for the power generation industry, ensuring they can perform safely, and according to the highest regulatory standards. No matter what kind of support or maintenance a filtration system needs, Croft is always on-hand.
