Abstract
Abstract Steam produced by a turbine in the course of generating electric power is released through conduit means into one or more surface condensers, where it is condensed. Heat exchange fluid contained in a closed system including a heat consumer outlet is continuously recycled under pressure through the one or more surface condensers wherein the fluid is warmed. When the heat exchange fluid is insufficiently cooled by passage through the heat consumer outlet, supplementary cooling means are provided to cool the heat exchange fluid prior to recirculation through the one or more surface condensers.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
246 words
In combination, a steam turbine, at least one surface condenser arranged to receive steam from said steam turbine, recirculation conduit means for continuously recycling a heat exchange fluid through said at least one surface condenser, said recirculation conduit means being arranged so as to permit said heat exchange fluid to exchange heat with said steam, pump means for unidirectionally circulating said heat exchange fluid through said recirculation conduit means so as to permit a recycle of said heat exchange fluid through said at least one surface condenser, said pump means being mounted in said recirculation conduit means, and supplementary cooling means for cooling said recycled heat exchange fluid prior to re-entrance through said at least one surface condenser including a liquid-to-liquid heat exchanger connected in the return piping of said recirculation conduit means, second conduit means for continously recycling a cool feed liquid through said liquid-to-liquid heat exchanger to cool said heat exchange fluid, said second conduit means being discrete in relationship to said recirculation conduit means, a source of cool liquid for circulation through said second conduit means and said liquid-to-liquid heat exchanger, said second conduit means connecting said supply of cool liquid and said liquid-to-liquid heat exchanger, one to the other, and pump means for unidirectionally circulating said cool liquid through said second conduit means so as to permit a recycle of said cool liquid through said liquid-to-liquid heat exchanger and said supply thereof, said pump means being mounted in said second conduit means.
Claim 2
Dependent Claim
246 words
In combination, a steam turbine, at least one surface condenser arranged to receive steam from said steam turbine, recirculation conduit means for continuously recycling a heat exchange fluid through said at least one surface condenser, said recirculation conduit means being arranged so as to permit said heat exchange fluid to exchange heat with said steam, pump means for unidirectionally circulating said heat exchange fluid through said recirculation conduit means so as to permit a recycle of said heat exchange fluid through said at least one surface condenser, said pump means being mounted in said recirculation conduit means, and supplementary cooling means for cooling said recycled heat exchange fluid prior to re-entrance through said at least one surface condenser including a liquid-to-liquid heat exchanger connected in the return piping of said recirculation conduit means, second conduit means for continously recycling a cool feed liquid through said liquid-to-liquid heat exchanger to cool said heat exchange fluid, said second conduit means being discrete in relationship to said recirculation conduit means, a source of cool liquid for circulation through said second conduit means and said liquid-to-liquid heat exchanger, said second conduit means connecting said supply of cool liquid and said liquid-to-liquid heat exchanger, one to the other, and pump means for unidirectionally circulating said cool liquid through said second conduit means so as to permit a recycle of said cool liquid through said liquid-to-liquid heat exchanger and said supply thereof, said pump means being mounted in said second conduit means.
Claim 3
Dependent Claim
161 words
The combination of claim 1 wherein said supplementary cooling means comprises a cooling tower adapted to cool a feed fluid, a jet condenser having a plurality of spray nozzles, said jet condenser being mounted in the steam space of said at least one surface condenser and being arranged in said steam space to release a measured spray of cool feed fluid into said steam space to condense steam received therein from said turbine, second conduit means for continuously recycling said cool feed fluid from said at least one surface condenser through said cooling tower to said jet condenser, said second conduit means being arranged to connect, in series, said at least one surface condenser, said cooling tower and said jet condenser, and pump means for unidirectionally circulating said cool feed fluid through said second conduit means so as to permit a recycle of said cool feed fluid through said jet condenser, said pump means being mounted in said second conduit means.
Claim 4
Dependent Claim
34 words
The combination of claim 2 including valve means for controlling the flow of cool feed fluid into said jet condenser, said valve means being mounted in said second conduit means proximate said jet condenser.
Claim 5
Dependent Claim
141 words
The combination of claim 2 wherein said at least one surface condenser comprises first and second surface condensers connected in parallel relationship relative to said steam turbine and serially connected in said recirculation conduit means, said first surface condenser being disposed below said second surface condenser, said second surface condenser being of lower pressure relative to said first surface condenser, and wherein said supplementary cooling means further include a second jet condenser having a plurality of spray nozzles, said second jet condenser being mounted in the steam space of said first surface condenser and being connected to the underside of said second surface condenser for receiving therein an admixture of cool liquid and condensate collected in said second surface condenser and re-releasing said admixture into said first surface condenser to condense steam received in said first surface condenser from said turbine.
