These are the large towers you will see at a coal fired power station amongst numerous other applications. e.g. In a coal fired power station, burning the coal heats water to produce steam which is in turn used to generate electricity. The water is usually taken directly from an adjacent river and then returned to the river. If the water was not cooled first then the temperature of the river water would rise and completely change the eco-system within. Therefore, the waste hot process water is passed through cooling towers. The shape of the cooling tower draws heat from the water, expelling it to the atmosphere before returning it to the river to minimise the rise in river temperature.

What are the advantages of induced draught cooling tower over forced draught cooling tower?
When a project is originally designed, the designer must decide whether a natural draft or mechanical draft tower offers the best economic result. Mechanical draft towers are substantially less costly to purchase, but have the disadvantage of having a continuous auxiliary power draw. They are also physically smaller and shorter. Natural draft towers consume no auxiliary power, but are very expensive to purchase and erect. They are very large and tall. Often times, plants do not have enough "real estate" to fit such a large structure. One must do an economic analysis to establish which option is the best choice, economically. They are also simpler, not having any moving parts
Where we can install the cooling tower And There is a company in which cooling tower is installed?
The Cooling tower is installed where the continuous heat rejection is required. Like process plants. Type is depends up on use & water property.
How cooling tower height is significant for cooling tower design?
There's quite multitude of things that impact a cooling performance. Specifically the height of the tower impacts on the the drafting air through the tower. See "Air Cooled Heat Exchangers and Cooling Towers" by Kroger for something more indepth.
What is cross flow cooling tower?
air will flow through across cooling tower
Is forced draft has negative pressure drop?
No, the forced draft fan has positive pressure as it just forces yhe air into the combustion chamber.only the induced draft fan has negative pressureas it removes the flue gases & exhaust gases is stacked up
Types of cooling tower?
There are dfferent types of cooling towers available in Industry. Some of the commonly is used cooling towers are Round Cooling Towers Square Cooling Towers Dry Cooling Tower Wooden Cooling Tower Cross Flow Cooling Tower Modular Cooling Towers Evaporative Cooling Towers Natural Cooling Towers Counter Flow Cooling Towers Get a highly durable cooling tower according to your industry.

What type of cooling is used in dry atmospheres in transformer?
forced air and draft oil dissipate
What is the difference between induced and forced draft cooling tower?
Induced draft --- A mechanical draft tower with a fan at the discharge (at the top) which pulls air up through the tower. 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/fin arrangement is also known as draw-through. (see Image 3)Forced draft --- A mechanical draft tower with a blower type fan at the intake. The fan forces air into the tower, creating high entering and low exiting air velocities. The low exiting velocity is much more susceptible to recirculation. With the fan on the air intake, the fan is more susceptible to complications due to freezing conditions. Another disadvantage is that a forced draft design typically requires more motor horsepower than an equivalent induced draft design. The benefit of the forced draft design is its ability to work with high static pressure. Such setups can be installed in more-confined spaces and even in some indoor situations. This fan/fill geometry is also known as blow-through.

Why Cooling tower are hyperbolic in shape?
Contrary to popular belief, the shape of a hyperbolic natural draft cooling tower has nothing to do with the airflow through it. The airflow through the tower is generated by the difference in density of the warm, humid air inside the tower, versus the relatively cool, dense ambient air outside the tower. This density difference causes a natural "draft" also known as the chimney or stack effect. If the temperature of the air outside the cooling tower is less than the temperature of air inside the cooling tower, the dense air outside forces the hot, humid air inside to travel upwards and thus provides the natural ventilation. For this reason you can see openings at the bottom of the hyperbolic cooling towers (Natural Draft Cooling Towers). Plant cooling water is sprayed over "fill" which is usually a grid of thin PVC sheets arranged in a honeycomb, placed near the lower end of the tower, just above the air openings at the bottom. The water is cooled by the natural draft of the ambient air traveling up through the fill, while the water cascades down the fill. Originally, natural draft cooling towers were cylindrical in shape. As the design of these types of towers evolved, and the towers were made increasingly larger, the cylindrical shape was changed to hyperbolic, since a hyperbolic shape offers superior structural strength and resistance to ambient wind loadings. For a structure of the size of some of these towers, the wind loading can be substantial.
How draft is produced in Cooling tower?
Two ways acting together:cool water is sprayed over the grid of hot pipes at the base of the tower, producing a cloud of water vapor which begins rising up the tower slowlythe constriction roughly two thirds the way up the tower forces the rising water vapor to accelerate, which greatly increases the draft
What are the causes of vibration in a induced draft cooling tower?
Causes of vibration in an induced draft cooling tower may include unbalanced fans, loose or worn fan belts, misaligned motor or fan shafts, or structural issues like loose bolts or deteriorating support structures. Regular maintenance, such as checking and adjusting fan components, aligning motor and fan shafts, and inspecting the tower's structural integrity, can help prevent vibration issues.
