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.

U.S. Pat. No. 3,498,590 to Furlong (1970) discloses the introduction of air, about the periphery of the lower portion of a tower, whereby the air so directed has a substantial direction parallel to the circumferential direction of the periphery as guided by partitions. Pipes are arranged about the outer circumference of the stack mouth to deliver compressed air, which is directed upwardly.

418,320 as being arranged within the tower near its mouth and further disclosed the introduction of air, of suitable temperature, towards or away from the axis of the tower. The Navier-Stokes equations describe a vortex formed in the chimney whereby the velocity of the air mass within the chimney structure is accelerated parallel to the vortex axis by the pressure differential within the vortex. The driving air force is introduced through and directed by means of vertically extending vanes which define a tower-like structure, to create a vortex flow, which draws ambient air into the bottom of the structure, to drive a horizontal turbine.
It can also be seen that the vortex core axis and the orifice axis will be coincident.
The fluid streams so introduced may be ambient air, or forced air, or flue gas effluent from a power plant, or a combination thereof. Such slots may be adjustable if desired, to provide that the fluid stream introduced at any point therethrough will enter the chimney structure approximately tangentially, with regard to the chimney walls. Analysis of the vortex fluid flow provides an indication of the dimensional relationships which will sustain a stable confined vortex with a desired flow within the cooling tower. It can also be seen that the vortex core axis and the orifice axis will be coincident. The diameter of orifice 22 through floor 20, centrally disposed through said floor 20 with regard to the central vertical axis of said chimney 12, is smaller than the diameter of said chimney sidewalls 16 at the point at which said sidewall communicates with fill 14. The size and positioning of orifice 22, which is thereby concentrically aligned in series with chimney mouth 32, is more fully explained in the Example.
It will be further appreciated that a tower having the aforementioned spiral type of configuration, may have only one slot whereby said slot is extended by confining sidewalls which circularly, rather than tangentially, direct a gaseous fluid flow towards the central axis of the chimney and the inner chimney core. 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. No. Dolor de pie en la planta . 4,070,131 to Yen, an embodiment designed to provide means for driving a wind turbine generator, by means of the tangential admission of air is disclosed.
FIG. 3 illustrates a sectional top view of an alternative embodiment of the chimney of FIG. DESCRIPTION OF THE DRAWINGS AND PREFERRED EMBODIMENT Referring now to the drawings and in particular to FIG. Of course, it may be desired that only one surface lip of orifice 22 be shaped as a venturi, in which case it is preferred that the lower lip be so shaped for the reason stated above. The walls of the chimney may somewhat aid in directing the formation of the vortex, but it is preferred that the walls only passively confine the vortex. FIG. 4 illustrates a tower 10 utilizing the teachings of the present invention and auxiliary means to supply forced gaseous fluid streams to augment the creation of or the efficient control of the vortex. Alternatively, as seen in FIG. The size of the resulting structure may be considered to be a severe visual impact which is further compounded when there are several plants at a given site, each with its own cooling tower.

No. 3,749,379 (1973), found that by increasing the cross-sectional area of the exhaust port, in conjunction with auxiliary fans within the tower sidewalls, a substantial increase in the height of the plume could be achieved. 4, or in combination with such aforementioned auxiliary means, as secondary directional means, forced gaseous fluid streams can be supplied by a forced draft fan supplying the same through duct 60 via a plenum chamber 62 which may encircle cooling tower 10 at or above fill 14. Ducts 64, which enclose and encompass slots 18 serve as conduits to provide said forced gaseous fluid streams to and through said slots 18. Nozzles 66, or other directional means, may be utilized to properly distribute the forced gaseous fluid streams to create said vortex such that the forced fluid streams traveling through ducts 64 are translated circumferentially and thereafter are directed tangentially into said chimney to create and maintain the vortex.
