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.
COOLING TOWER SYSTEM • The water pumped from the tower basin is the cooling water routed through the process coolers and condensers in an industrial facility. • The cool water absorbs heat from the hot process streams which need to be cooled or condensed and the absorbed heat warms the circulating water (C).
A cooling tower is a heat removal device that uses water to transfer process waste heat into the atmosphere. All cooling towers operate on the principle of removing heat from water by evaporating a small portion of water that is recirculated through the unit. The mixing of warm water and cooler air releases latent heat of vaporization, causing ...

The area of ribbed tubes is used for the heat transfer where the cooling air flows outside the tubes, and the condensing medium, steam, flows inside the tubes. Forced air flow is provided by a propeller fan. The fan is driven by an electric motor with gearbox. The air cooler (AC) is used for cooling the heat transferring media. In principle, it ...

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.
Cooling tower Wikipedia Industrial cooling towers can be used to remove heat from various sources such as machinery or heated process material. The primary use of large, industrial cooling towers is to remove the heat absorbed in the circulating cooling water systems used in power plants, petroleum refineries, petrochemical plants, natural gas ...
As a result drift losses can now be as low as 0.003 – 0.001%. 4.4 Cooling tower fans The purpose of a cooling tower fan is to move a specified quantity of air through the system. The fan has to overcome the system resistance, which is defined as the pressure loss, to move the air.

Pumps & Cooling Towers • Fixed speed primary, condenser and variable speed secondary pumping • Trend towards variable primary flow • Power consumptions less than 0.2 KW/TR • Chiller - Cooling Tower Optimization • Select with the best approach
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 ...
Cooling towers can be small- scale roof-top installations, medium-sized packaged units, or very large structures sometimes associated with industrial processes or power stations with their characteristic plume of water vapour in the exhaust air. These large cooling towers can be up to 200 metres (660 ft) tall and 100 m (320 ft) in diameter.
tower performance. For example, a cooling tower sized to cool 4540 m3/hr through a 13.9 °C range might be larger than a cooling tower to cool 4540 m3/hr through 19.5 °C range. Therefore other design parameters are also needed. 4.1.2 Range Range is determined not by the cooling tower, but by the process it is serving. The range at the
For large Cooling towers (especially power plants), water treatment is the key area for energy conservation. Efficient System Operation of a Cooling tower . Drift loss •Should be less than 0.02% of the circulation rate •With technological development, incorporation of
Cooling Tower Build Type . Cooling towers can differ by build as well as heat transfer and air generation methods. When it comes to cooling tower build, there is the: Package type. These are small, compact, and pre-fabricated cooling towers used for smaller industries, such as hospitals or schools. These are factory fabricated and ship on trucks
a) Induced Draft Cooling Tower : In this type of mechanical cooling tower a powerful fan is installed unit at the top of the tower. Due to this when this fan is get on produces low entering and high exiting air velocities just like a powerful exhaust fan. The presence of this powerful exhaust fan eliminates the risk of re-circulation.
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.
The cooling component of this new electricity station is a natural draft cooling tower 200 m high, the tallest cooling tower and the largest shell structure in the world.

Cooling capacity. The cooling capacity of a tower is the heat rejected [kcal/h or TR (refrigeration tons; 1. TR = 12,000 Btu/h = 3,025.9 kcal/h)], and is determined by the product of mass flowrate of water, times. the specific heat times the temperature difference. Theory — the Merkel equation.
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.

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.
