Abstract
The present invention relates to a natural draft cooling tower that employs an air cooled condenser. The aforementioned cooling tower operates by natural draft and achieves the exchange of heat between two fluids such as atmospheric air, ordinarily, and another fluid which is usually steam. The aforementioned cooling tower utilizes a central steam duct riser supplying steam to perimeter ducting via radial ducting.

A natural draft cooling tower that cools an industrial fluid that comprises an air cooled steam condenser, comprising:
- a shell having a perimeter that extends vertically about a vertical axis, wherein the air cooled steam condensers are disposed approximate to said shell;
- a horizontal duct that receives the industrial fluid to be heated;
- a central riser duct in fluid communication with said horizontal duct;
- a radial manifold in fluid communication with the central riser duct.
- at least one radial duct that extends radially from said radial manifold;
- a terminal duct in fluid communication with said at least one radial duct;
- a peripheral manifold in fluid communication with said terminal duct;
- and
- at least one finned tube bundle in fluid communication with said peripheral manifold.
A method for cooling an industrial fluid using a natural draft cooling tower, the method comprising:
- flowing the industrial fluid to be cooled through a horizontal duct;
- flowing the industrial fluid to be cooled through a central riser duct supported by a fixed point;
- flowing the industrial fluid to be cooled through a radial manifold;
- flowing the industrial fluid to be cooled through at least one radial duct and a terminal duct to a peripheral manifold;
- flowing the industrial fluid to be cooled through the peripheral manifold to at least one finned tube bundle;
- and
- passing an airflow over the finned tube bundles and inducing heat exchange on the industrial fluid via said airflow.
A natural draft cooling tower that cools an industrial fluid that comprises an air cooled condenser of the dry-type, comprising:

- a horizontal duct that receives the industrial fluid to be cooled;
- a central riser duct in fluid communication with said horizontal duct;
- a radial manifold in fluid communication with the central riser duct;
- at least one radial duct that extends radially from said radial manifold;
- a terminal duct in fluid communication with said at least one radial duct;
- a peripheral manifold in fluid communication with said at least one radial duct;
- at least one finned tube bundle in fluid communication with said peripheral manifold;
- and
- a cooling tower support structure, comprising:
- a chimney section,
- a base section, wherein said base section comprises a first airflow inlet at a first vertical position;
- a second airflow inlet located at second vertical position, wherein said second airflow comprises an air regulating means that translate between an open and closed position.
A system, comprising:
- means for flowing an industrial fluid to be cooled through a horizontal duct;
- means for flowing the industrial fluid to be cooled through a central riser duct;
- means for flowing the industrial fluid to be cooled through a radial manifold;
- means for flowing the industrial fluid to be cooled through at least one radial duct and a terminal duct to a peripheral manifold;
- means for flowing the industrial fluid to be cooled from the peripheral manifold to at least one finned tube bundle;
- and
- means for passing an airflow over said at least one finned tube bundle and inducing heat exchange on the industrial fluid via said airflow.
