Abstract
Abstract In air-cooled condensation apparatus having a natural-draft cooling tower, condensation elements are disposed not only at the outer periphery of the cooling tower but also in at least one ring located in the interior of the cooling tower coaxially to the condensation elements at the outer periphery, the cooling elements located in the interior of the cooling tower being operable in winter dephlegmatorically, i.e., with steam flowing into the cooling tower from below.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
In air-cooled condensation apparatus for steam power plants, a natural-draft cooling tower having at least two groups oF condensation elements, a first of said groups being disposed at the base of the cooling tower along the outer periphery thereof, a second of said groups being disposed along a circle located within the cooling tower and coaxial to the outer periphery of the cooling tower, means for disposing said first of said group of condensation elements at an elevation parallel to a cooling air flow passing through said condensation elements at the outer perphery, thereby enabling an additional flow of cooling air directed to said first group of condensation elements disposed in the interior of the cooling tower to pass beneath said first group of condensation elements at the outer periphery.
Claim 2
Dependent Claim
130 words
In air-cooled condensation apparatus for steam power plants, a natural-draft cooling tower having at least two groups oF condensation elements, a first of said groups being disposed at the base of the cooling tower along the outer periphery thereof, a second of said groups being disposed along a circle located within the cooling tower and coaxial to the outer periphery of the cooling tower, means for disposing said first of said group of condensation elements at an elevation parallel to a cooling air flow passing through said condensation elements at the outer perphery, thereby enabling an additional flow of cooling air directed to said first group of condensation elements disposed in the interior of the cooling tower to pass beneath said first group of condensation elements at the outer periphery.
Claim 3
Dependent Claim
26 words
Apparatus according to claim 1 wherein said disposing means comprise support members whereon said first group of condensation elements located at the outer periphery are mounted.
Claim 4
Dependent Claim
34 words
Apparatus according to claim 1 including flow guide surface means mounted in the cooling tower for guiding the additional cooling air flow to said condensation elements disposed in the interior of the cooling tower.
Claim 5
Dependent Claim
28 words
Apparatus according to claim 1 wherein a plurality of steam lines extend from a steam distributor to said first of said condensation elements in a downwardly inclined position.
Claim 6
Dependent Claim
21 words
Apparatus according to claim 1 including control means for selectively operating said outer condensation elements and said inner condensation elements dephlegmatorically.
Claim 7
Dependent Claim
54 words
Apparatus according to claim 5 including a steam distributor disposed within the cooling tower and a plurality of steam lines extending from said distributor to said condensation elements, said control means comprising a cylindrical ring disposed within said steam distributor, said ring being displaceable so as to close respective inlets to said steam lines.
Claim 8
Dependent Claim
34 words
Apparatus according to claim 6 including hydraulic means disposed in said steam distributor for displacing said cylindrical ring into and out of positions wherein inlets to said steam lines are selectively opened and closed.
