Natural Draft Cooling Towers

Additional Details

The Natural draft cooling towers are particularly pretty as a cost-saving solution for power plants and other industrial plants requiring larger quantities of cooling water. Natural Draft cooling tower operates without fans and Fills, the large amount of electric power or else required for large cooling tower systems is not required. The mandatory cooling air is pass on through the tower by natural draft henceforth neither fan nor fan power is required for these kind of Cooling Solution. No maintenance required like other Wet (or) Dry Cooling Towers. By using of Non clock nozzle are easy to cleaning reduce spillage and evaporation loss. Hot Dipped Galvanized Structural's and S.S.fasteners increase the lifetime as well as the efficiency of the cooling tower it can be installed for any range of cooling application.

Structure: Is made from heavy M.S.Angle/Tee/Channel sections and Hot Dipped Galvanized or lined with FRP for corrosion resistance.

Louvers: Are made from Fiberglass Reinforced Plastics which ensures corrosion resistance and good mechanical properties.

Water Distribution Headers: Are made from "c" class galvanized pipe/PP FRP coated pipes.

Nozzles: Are made from Rigid PVC (or) Brass Nozzle to give good corrosion resistance.

Nuts and Bolts: Are made from Stainless Steel (or) HDG Bolt and Nuts.

Features and Functions of Natural Draft Cooling Towers:-

Natural Draft Cooling Tower especially hold attraction as solution for saving costs for large industrial plants and power stations; that require large amounts of cooling water.The needed cooling air is transported to the tower with the help of natural draft. Hence there is no necessity for fan or fan power. This is co-current cooling tower. Air and water both travel together in the same direction from top to bottom. Hot water is allowed to spray through specially designed nylon/pp nozzles at minimum 0.5 kg./ sq. cm pressure. Water enters nozzle tangentially at top and is given spiral action in spiral chamber. This spiral action increases as water approaches the discharge orifice and comes out centrally from discharge orifice with fine droplets in umbrella shape. Air around the nozzle is sucked because of air displacement at a lower level near discharge orifice and fresh dry air takes its place.This assures better contact of air and water and the high cooling efficiency.

The Fanless, Filless Induced Draft design has been developed after a detailed research and analysis of the engineering design. This design allow as a substantantial saving in power consumption.Also, the common problems of breakdown and maintence of cooling tower are eliminated to a large extent with this design. It is also used for the release of treated exhaust gas. It also implies that there is no need of gas reheating or chimney. PVC Fills, motor, fan are not required by Natural Draft Cooling Towers. FRP Louvers that are specially designed aerodynamically, minimize evaporation loss and spillage.
