RCC Cooling Tower
The Cooling Towers are designed by construction of two types. They are Field-Erected and Factory-Assembled. Rcc Cooling Tower is cement concrete based cooling towers. The maintenance of rcc cooling towers is low compared to timber cooling towers.
The Rcc cooling towers are categorized into two segments as Cross flow and counter flow.
Cross flow is designed in which the air flow is directed perpendicular to the water flow. Air flow enters one or more faces of the cooling tower to meet the filling requirement. Water flows through the fill by gravity. A hot water basin consisting of a deep pan with nozzles in its bottom is placed near the top of a crossflow cooling tower.
Counter flow is designed in which the air flow is opposite to the water flow. The water is sprayed through pressurized nozzles near the top of the tower, and flows down throught the fill, opposite to the air flow.
The advantages of these cooling towers is both cross flow and counter flow designed cooling towers can be used in natural draft and in mechanical draft cooling towers. A cold water basin is used to collect and contain the cooled water after its interaction with air flow.
