Description of FRP Natural Draft Towers
The traditional natural draft cooling towers made of FRP or timber, commonly known as fanless or fill-less cooling towers, do not require the use of fans or fills to cool the water. In the case of timber atmospheric/fanless cooling towers, treated wooden louvers are utilized as side walls to prevent water spillage and allow for the passage of outside wind, which serves as the cooling medium.
In fanless cooling towers, hot water is sprayed at the top with spray nozzles, forming small droplets that are cooled by the atmospheric wind flow. This same technique is applied in FRP fanless/natural draft/fill-less cooling towers, using FRP louvers instead of expensive timber ones. These cooling towers are highly cost-effective, as they do not require a fan or electric motor, resulting in minimal operating and maintenance expenses.
The primary purpose of FRP cooling towers is to maintain a specific temperature level of process hot water by cooling it down. Ascent Machineries & Engg. Services fabricate these towers using the latest technology, making them robust and durable. Designed for use in commercial and industrial settings, they are highly resistant to wear and tear. Additionally, FRP cooling towers are lightweight, corrosion-resistant, compact, portable, and easy to install and maintain, making them a customer favourite.
Natural Draft Cooling Tower Working
FRP (Fiber Reinforced Plastic) Natural Draft Towers, also known as atmospheric cooling towers, work on the principle of natural convection. These towers use the difference in temperature between the hot water entering the tower and the cooler ambient air to transfer the heat and cool the water.
The FRP Natural Draft Towers have a large vertical column or chimney that is open at the top and bottom. The hot water from the industrial process is pumped to the top of the tower and then sprayed onto the fill material inside the tower. The fill material is designed to increase the surface area of the water, which allows for more efficient heat transfer to the ambient air.
As the water flows downward through the fill material, it is exposed to the ambient air, which is cooler than the hot water. The heat from the water is transferred to the air through the process of evaporation. The evaporated water rises, creating a natural draft of air inside the tower, which pulls in cooler air from the surroundings and continues the cooling process.
The cooled water is collected at the bottom of the tower and then pumped back to the industrial process to maintain the required temperature. The FRP cooling tower function without the need for any external power source or fan, making them highly energy-efficient and cost-effective.
Overall, the working principle of FRP Natural Draft Towers relies on the natural convection process, utilizing the difference in temperature between the hot water and ambient air to transfer heat and cool the water.
