To provide the same cooling capability as an aforementioned conventional evaporative cooling tower having a base diameter of about 400 feet and a height of about 500 feet, a confined vortex cooling tower, using the teachings of this invention, will have a base diameter of about 350 feet and a height of about 200 feet. The invention provides heat or other effluent constituent removal such as heat transfer from a cooling fluid and removal of pollutants when embodied such as in a natural draft cooling tower which is either of the nature of a wet or dry system. Stephens introduces air tangentially, which air is upwardly directed into the tower through the sidewalls, to reduce the necessity of wind ejectors which are embodied as roofs. Further, the resultant effective height of the vapor plume from a mechanical draft tower is closer to ground level than that from a natural draft tower and consequently presents the possibility of ground fogging and icing which is frequently unacceptable.

The present invention provides means for significantly reducing, for example, both the height and diameter of natural draft evaporative or dry cooling towers, for a particular cooling capacity, as compared to conventional natural draft evaporative or dry towers while retaining, and, at times increasing, the effective height of the vapor plume, in the case of evaporative towers. It may provide more effective tower drift removal, elimination of smoke-stack structures and the elimination of reheat requirements for the gases emanating from wet process scrubbers. The evaporative process involves the use of atmospheric cooling air which passes through heat transfer passages in the fill below the chimney portion of the structure and which entrains a small fraction of the condenser circulating water which has evaporated. At least one gaseous fluid stream is introduced through the walls of the chimney structure tangentially, with respect to the said chimney walls, by means of at least one vertical slot, extending for substantially the height of said chimney.

Specifically, the confined vortex core and resulting augmentation of gaseous fluid flow within said fill cavity produce a significantly accelerated axial flow field within the tower structure creating an upward rush of the combined fluid flows which enhance the cooling, for example, of hot condenser circulating water or other coolant moving through heat transfer embodiments in the fill at the base of a wet or dry tower. It will be appreciated that the mass flow of any effluent containing gaseous fluid, such as for example, flue gases in a stack, will similarly be enhanced. A 1,000 MW fossil fuel plant, for example, may require approximately, 500,000 gallons per minute (gpm) of cooling water, while a similarly sized nuclear plant may require 750,000 gpm. These towers require approximately one-fiftieth the amount of water withdrawal from a body of water as is required by an open-cycle type of cooling means for power plant condensers.

Within the last decade, with the advent of large electric generating plants, which range in output from 600 megawatts (MW) for fossil-burning plants to 1,200 MW for nuclear plants and which have large cooling requirements associated therewith, and with the advent of environmental constraints, mechanical and natural draft cooling towers have become a primary means of cooling power plant condensers.

In the case of a cooling tower, such effluent containing gaseous fluid streams will consist essentially of cooling gaseous fluid streams, introduced into said fill cavity, to which heat has been transferred. The orifice permits the low pressure core of said confined vortex to entrain gaseous fluid flow from said fill cavity thus enhancing the flow regime and transfer capability of said effluent transfer or removal gaseous fluid streams, such as cooling gaseous fluid streams in a cooling tower, within said fill cavity. Such confined vortex augments an upward draft effluent flow which enters the chimney from a cavity in the fill and which is entrained by the vortex through an orifice in a floor of the tower.
