cooling tower

Stretch it back again.

We're not gonna give you another cooling tower until you explain how you broke this one.

Are you a cooling tower designer, or are you doing homework? Any road, here's a site that helps students with cooling tower questions.

Add a fan to push more air through it

Make it bigger around.

Add a VSD and 1 or 2 of the following:

spray pump

damper w/ actuator that is proportional to temperature

or all 3, but you must not interfere w/ motor windings or cause misting/ flow pattern that would make existing air flow pattern inefficient.

Hi..

"if a hyperbolic cooling tower turns into cylinderical cooling tower of lesser height" What do you mean by lesser height. Today a 25000Cum/hr normal flow cooling tower for a 210MW coal fired power station is about 120 meter height. Similarly a 500MW Nuclear power station will need a 100000Cum/hr capacity cooling tower of 165 meter height. What heights are you speaking of?

It is the hyperbolic shape which induces the natural draught. No energy is expended to run them although quite a bit is consumed in building these monsters.

During the initial years there were short height cylinderical cooling towers which were of forced draught design i.e. you had to pump air through the bottom part of the cylinder in order to create the draught. These were later discarded as more efficient induced draught cooling towers were developed & natural draught cooling tower construction took off properly.

Add packing to the tower so as to increase mass transfer rates.
