Natural Draft Cooling Tower

[Janisrossa]

Hello
I am engineer on a Coal Power Station. Currently I am working on a project about a Natural Draft Cooling Tower that will be used to replace a wet cooling tower and a stack. Although I could not find any information about it.
If somebody have a clue about this system or a tip where I can find it (books, papers or other biography), I would be grateful.
thanks a lot.

I don't quite understand your terminology. Most natural draft cooling towers I have ever seen were wet unless you mean that you are going to a dry tower.

I am looking for technical information about Natural Draft Cooling Towers (please see

http://www.nucleartourist.com/images/ct-natur.jpg).

These tower types don't use fans to create the air flow and their geometry is based on a hyperbolic. I am most interstated on wet towers.
Thanks rmw by link.

OEMs would also be a good source of info.

Google the words "hyperbolic cooling tower" without the "-".

Here are some of the first hits I got.

Precision Cooling Towers in KY apparently do these. I checked one or two other major tower vendor websites and didn't see any obvious reference to natural draft towers.

I recall that about 4 yrs ago the journal "modern power systems" had reported on a dry hyperbolic cooling tower ( in Turkey?) for a large coal fired unit. see <
