Abstract
Abstract A wet cooling tower has an encircling exhaust header in communication with the exhaust of a plurality of gas turbines and a plurality of upwardly inclined conduits, which direct the hot exhaust gas tangentially into the cooling tower to increase the temperature and velocity of the moisture laden air flowing therethrough to lift the effluent air into the upper atmosphere and eliminate the plume under many weather conditions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
In combination a wet cooling tower, a header subtending at least a portion of said cooling tower, means for supplying hot gases to said header, a plurality of conduits extending from said header into said cooling tower, each of said conduits being inclined upwardly and being generally disposed tangentially with respect to a circle disposed within the cooling tower, whereby hot gases flowing through said conduits follow a generally upwardly swirling path increasing the temperature and velocity of the upwardly flowing moisture laden air inducing mixing and lifting the moisture laden air into the upper atmosphere.
Claim 2
Dependent Claim
96 words
In combination a wet cooling tower, a header subtending at least a portion of said cooling tower, means for supplying hot gases to said header, a plurality of conduits extending from said header into said cooling tower, each of said conduits being inclined upwardly and being generally disposed tangentially with respect to a circle disposed within the cooling tower, whereby hot gases flowing through said conduits follow a generally upwardly swirling path increasing the temperature and velocity of the upwardly flowing moisture laden air inducing mixing and lifting the moisture laden air into the upper atmosphere.
Claim 3
Dependent Claim
14 words
The combination set forth in claim 1, wherein the header encircles the cooling tower.
Claim 4
Dependent Claim
24 words
The combination set forth in claim 1, wherein the header decreases in cross-sectional area from that portion which is connected to the supply means.
Claim 5
Dependent Claim
32 words
The combination as set forth in claim 1, wherein the means for supplying hot gases to the header comprises at least one gas turbine having its exhaust in communication with the header.
Claim 6
Dependent Claim
29 words
The combination as set forth in claim 1, wherein the means for supplying hot gases comprises a plurality of gas turbines having their exhaust in communication with the header.
Claim 7
Dependent Claim
50 words
The combination as set forth in claim 1, wherein the cooling tower has holes disposed therein for accepting the conduit means and the holes are larger than the conduit means to allow for expansion and to prevent the transfer of the heat from the conduit means to the cooling tower.
