Abstract
Abstract A forced-air cooled condenser system having a plurality of roof-shaped heat exchange elements of finned tubes, to which cooling air is supplied via fans, and to which the steam which is to be condensed is supplied via a steam distribution line which forms the ridge of the elements. The heat exchange elements, which are located directly adjacent to the turbine housing, are disposed next to one another or side by side. The ridges of the heat exchange elements are disposed parallel to one another. In order to prevent the danger of a recirculation of the warm air which leaves the heat exchange elements, that heat exchange element which is spaced the furthest from the turbine housing is disposed higher than the heat exchange elements which are located therebetween. This is preferably accomplished via higher supports than exist for the heat exchange elements located therebetween.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
181 words
In a forced-air cooled condenser system having a plurality of roof-shaped heat exchange elements of finned tubes, to which cooling intake air is fed via fans, and to which steam which is to be condensed is fed via steam distribution lines, each of which forms a ridge of a given one of said heat exchange elements; the heat exchange elements are disposed directly by a turbine housing, and are disposed next to one another or consecutively, with the ridges of said heat exchange elements being disposed parallel to one another; the improvement therewith which comprises having that heat exchange element, which is spaced the furthest from said turbine housing, arranged structurally higher than the heat exchange elements located therebetween so that, on one hand, in-flow losses of intake air can be reduced thereby having a favorable effect upon power required for cooling, and on the other hand, considerably reducing danger of recirculation of warmed air from the heat exchange elements due to inclined upwardly directed direction due to higher arrangement of that heat exchange element spaced furthest from said turbine housing.
Claim 2
Dependent Claim
181 words
In a forced-air cooled condenser system having a plurality of roof-shaped heat exchange elements of finned tubes, to which cooling intake air is fed via fans, and to which steam which is to be condensed is fed via steam distribution lines, each of which forms a ridge of a given one of said heat exchange elements; the heat exchange elements are disposed directly by a turbine housing, and are disposed next to one another or consecutively, with the ridges of said heat exchange elements being disposed parallel to one another; the improvement therewith which comprises having that heat exchange element, which is spaced the furthest from said turbine housing, arranged structurally higher than the heat exchange elements located therebetween so that, on one hand, in-flow losses of intake air can be reduced thereby having a favorable effect upon power required for cooling, and on the other hand, considerably reducing danger of recirculation of warmed air from the heat exchange elements due to inclined upwardly directed direction due to higher arrangement of that heat exchange element spaced furthest from said turbine housing.
Claim 3
Dependent Claim
44 words
A condenser system according to claim 1, which includes supports for said heat exchange elements; the supports for said heat exchange element which is spaced the furthest from said turbine housing being structurally higher than the supports for the heat exchange elements located therebetween.
Claim 4
Dependent Claim
23 words
A condenser system according to claim 2, in which said supports increase incrementally in height as distance thereof from said turbine housing increases.
Claim 5
Dependent Claim
19 words
A condenser system according to claim 3, in which said heat exchange elements are individually disposed on said supports.
Claim 6
Dependent Claim
32 words
A condenser system according to claim 3, in which said heat exchange elements are disposed on said supports in groups comprising several heat exchange elements which are disposed next to one another.
Claim 7
Dependent Claim
51 words
A condenser system according to claim 3, which includes vertical planes between individual heat exchange elements for intake air for said fans; said vertical planes having cross-sectional areas which vary in conformity with the varying heights of said supports, and which are adapted to the air requirements of the respective fans.
