1.1 Cooling Tower A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water's temperature. As this occurs, a small volume of water is evaporated, reducing the temperature of the water being circulated through the tower.
Unlike conventional oil / gas fired and also other solar-thermal power plants, Solar Updraft Towers do not need cooling water. This is a key advantage in many sunny countries that already have major problems with water supply. Electricity from Solar Updraft Towers is the cheapest when compared with other solar power plants.
Hybrid wet/dry cooling systems use some combination of wet and dry cooling to reduce water consumption. Several recent plants built to conserve water have used a parallel cooling system (PCS), which uses both an air cooler (typically smaller than that us air-cooled-only plant) and a small wet cooling tower operating in parallel for us

Nov 28, 2012· CT effectiveness of my cooling tower = 100 x (41-31) / (41-27.4) = 73.53% Cooling Capacity This is the heat rejected in kCal/hr, given as product of mass flow rate of water, specific heat and temperature difference.
certified loss prevention products including evaporative water cooling towers. An FM Approved cooling tower is one that has satisfied the historic testing protocol or one that has satisfied the requirements and acceptance criteria of the Modern Approval Standard for Cooling Towers (Class 4930).
Dec 25, 2011· A cooling tower is an equipment used to reduce the temperature of a water stream by extracting heat from water and emitting it to the atmosphere. This figure shows a cooling tower. Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere.
Factors affecting Cooling tower performance Capacity utilization Amount of water circulated Range Determined by the process it is serving Determined by heat load and water circulation rate Thus Range: f (Heat load & water circulation rate) Wet Bulb temperature: design range is specified at certain WBT The closer the approach to the WBT, the more expensive the
L = Mass flow of water entering the cooling tower — lb/min t. 1 = Hot water temperature entering the cooling tower — °F w = Cold water temperature leaving the cooling tower — °F This derives from the fact that a Btu (British thermal unit) is the amount . of heat gain or loss necessary to change the temperature of 1 pound of water by 1°F.

Drift loss of the cooling tower is normally provided by the cooling tower manufacturer based on the Process design. If it is not available it may be assumed as For Natural Draft Cooling Tower D = 0.3 to 1.0 * C /100 For Induced Draft Cooling Tower D = 0.1 to 0.3 * C /100 For Cooling Tower with Drift Eliminator D = 0.01* C /100
Cooling towers are usually designed for specific purposes. Not all cooling towers work for all applications or industrial processes. Here we help you understand the various types of cooling towers, there advantages/disadvantages and determine which cooling tower …
Jul 15, 2018· • A cooling tower is an enclosed tower like structure through which atmospheric air circulates to cool large quantities of warm water by direct contact. • Cooling towers are a very important part of many plants. • Cooling tower is to reject heat into the atmosphere. • Removing low-grade heat from cooling water.

The thermal capability of a cooling tower used for air condition- ing is often expressed in nominal cooling tower tons. A nominal cooling tower ton is defined as cooling 3 gpm of water from 95°F to 85°F at a 78°F entering air wet-bulb temperature. At these condi- tions, the cooling tower rejects 15,000 Btuih per nominal cooling tower ton.

Mar 29, 2018· Cooling towers are a distinct sort of heat exchanger, which permits water and air to get in connection with each other to reduce the temperature of the boiling water. Through the process of a cooling tower, tiny quantities of water tend to evaporate which help to drop the temperature of the water that has been sustained in the cooling water.

cooling tower performance. Other factors, which we will see, must be stated along with flow rate m3/hr. For example, a cooling tower sized to cool 4540 m 3/hr through a 13.9°C range might be larger than a cooling tower to cool 4540 m3/hr through 19.5°C range. Range Range is determined not by the cooling tower, but by the process it is serving.
the cooling tower. The number 500 is a constant, therefore is independent of the cooling tower. The circulating water flow is determined by the number of pumps running and the pressure drop in the overall circulating water system. Therefore, it likewise is independent of the cooling tower.
Feb 06, 2020· An Induced draft cooling tower is a mechanical draft tower with a fan at the discharge to pull air through it. The fan induces hot moist air out the discharge. This produces low entering and high exiting air velocities, reducing the possibility of recirculation in which discharged air flows back into the air intake.This fan/fill arrangement is
Dec 20, 2019· Forced Draft. A forced draft cooling tower has a fan at the cooling tower’s air intake. The fan blows air into the cooling tower. Pros: Able to work with high static pressures, so can be installed in tight spaces where airflow may be restricted. Cons: Airflow exiting the cooling tower is low velocity, so it can be prone to recirculating back into the tower, reducing the tower’s efficiency.
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
