Design and Fabrication of Cooling Tower

A cooling tower is a heat rejection device which extracts waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed ...

COOLING TOWERS - University of Alabama

cooling towers, but do affect the rate of water evaporation in the cooling tower. A psychromehic analysis of the air passing through a cooling tower illustrates this effect (Figure 2). Air enters at the ambient condition Point A, absorbs heat and mass (moisture) from the water. and exits at Point B in a saturated condition (at verv light d "

Cooling Tower Performance

cooling towers, air density differences play a role in determining the air flow. The approach of a cooling tower varies directly with the heat load of a process. Heat load is defined as the total heat to be removed from the circulating water by the cooling tower per unit time

by fans into the cooling tower and up through the flow of falling water in the cooling tower. Drift eliminators are installed to prevent water entrained in the air from leaving the system. 1.3.3 INDUCED-DRAFT TOWERS. The term "induced draft" denotes that air is drawn by fans through the flow of falling water and up and out of the cooling tower.

Cooling Tower Efficiency Calculations Cooling Tower …

Cooling tower efficiency is limited by the ambient wet bulb temperature. In ideal case the cold water temperature will be equal to the wet bulb temperature. This is practically not possible to achieve. This . requires very large tower and results in huge evaporation and windage or drift loss resulting in a

Design and Analysis of Cooling Tower

Cooling towers are an essential part of Power plants. The primary job of a cooling tower is to discard heat into the environment. Hot water from Condenser is sent to the cooling tower. The water exits the cooling tower and is sent back to the boiler for further process. In cooling towers, air is passed alongside or counter at present with water.

Natural Draught Cooling Tower Artistic to Scientific Design of Cooling Towers The art of evaporative cooling is quite ancient, although it is only relatively recently that it has been studied scientifically. Merkel developed the theory for the thermal evaluation of …

THE BASICS OF COOLING TOWER WATER TREATMENT

Cooling is accomplished through the latent heat of vaporization. For each pound (.121 gallons) of water that a cooling tower evaporates it removes about 1,000 BTU's from the liquid that remains. As evaporation increases more heat is removed. Water vapor evaporates, leaving dissolved or suspended solids in the re-circulating cooling water.

7. COOLING TOWER - Bureau of Energy Efficiency

Cooling towers fall into two main categories: Natural draft and Mechanical draft. Natural draft towers use very large concrete chimneys to introduce air through the media. Due to the large size of these towers, they are generally used for water flow rates above 45,000 m3/hr. These types of towers are used only by utility power stations.

What is a Cooling Tower - Cooling Tower Basics

A cooling tower is a device that rejects heat to the atmosphere by cooling a working fluid (typically water) to a lower temperature. In a chiller plant, this water is part of the condenser water loop, and is responsible for removing …
