Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
158 words
In a steam condenser, a temperature controlled source water system comprising a combined concrete supporting structure and cooling water outlet chamber , a cooling water inlet, at least one shell superimposed on the source water outlet having at least one vent for non-condensables, a plurality of modules with replaceable tubes positioned therein at an angle from the horizontal and tube sheets at each end of the tubes spacing and sealing the tubes in the modules. at least one manifold communicating between the cooling water inlet connection and one of said tube sheets in each module to direct the cooling water through the tubes, a steam dome superimposed on said shell to direct steam between said tubes and shell, at least one hotwell located below the shell having a positive reheating-deaeration system comprising at least one reheating tray, a condensate collecting trough beneath the tubes to convey condensate from the tubes to the tray, and a condensate discharge outlet.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
42 words
The steam condenser of claim 1, wherein the modules further comprise intermediate plates for supporting; said tubes and each said intermediate plates has one of said collecting troughs coupled thereto and extending therefrom, for collecting condensate for channelling to the reheating-deaerations system.
Claim 4
Dependent Claim
21 words
The steam condenser of claim 1, wherein the steam dome further comprises a concave surface for increased support and improved flow.
