Abstract
Abstract A power plant having a condenser is provided with a selfadjusting water-feed system in which a first pump draws water from the primary source (e.g. a stream, lake or reservoir), feeds the water through a passage. A second pump draws the cooling water from the passage and supplies it to the condenser, and the water from the condenser flows through another passage in which the flow is adjusted by a level control. A bypass connects the two passages so that flow between them to adjust the temperature is possible solely by control of the relative levels at the source and the ultimate receptacle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
82 words
A method of operating a cooling supply system for the condenser of a power plant which comprises the steps of: pumping cooling water from a source through a cooling water channel at a first location; pumping water from said channel at a second location through said condenser and through a warm-water channel; bypassing said channels into one another; and controlling the flow of water from one channel into the other at the bypass solely by the relative rates pumped at said location.
Claim 2
Independent Claim
82 words
A method of operating a cooling supply system for the condenser of a power plant which comprises the steps of: pumping cooling water from a source through a cooling water channel at a first location; pumping water from said channel at a second location through said condenser and through a warm-water channel; bypassing said channels into one another; and controlling the flow of water from one channel into the other at the bypass solely by the relative rates pumped at said location.
Claim 3
Dependent Claim
20 words
The method defined in claim 1, further comprising the step of maintaining a constant water head in said warm-water channel.
Claim 4
Dependent Claim
109 words
A cooling water system for the condenser of a power plant, comprising: a source of cooling water; a first pump connected to said source for displacing cooling water at a first rate; a cooling water channel connected to said first pump for conducting the cooling water therefrom; a second pump drawing water from said cooling channel and pumping it through said condenser at a second rate; a warm-water channel connected to said condenser for conducting warm water therefrom; and a valveless bypass interconnecting said channels for permitting selected flow from one of said channels to the other in either direction through said bypass in dependence upon the relative rates.
Claim 5
Dependent Claim
109 words
A cooling water system for the condenser of a power plant, comprising: a source of cooling water; a first pump connected to said source for displacing cooling water at a first rate; a cooling water channel connected to said first pump for conducting the cooling water therefrom; a second pump drawing water from said cooling channel and pumping it through said condenser at a second rate; a warm-water channel connected to said condenser for conducting warm water therefrom; and a valveless bypass interconnecting said channels for permitting selected flow from one of said channels to the other in either direction through said bypass in dependence upon the relative rates.
Claim 6
Dependent Claim
125 words
The system defined in claim 3 wherein said cooling water channel comprises a duct having an inlet side and an outlet side, means forming a column adapted to sustain a water head at said inlet side, said first pump being connected to said duct at said inlet side, said second pump being connected to said duct at an outlet side thereof and said bypass being connected to said duct intermediate said inlet and outlet sides; a supply reservoir is provided between the intake of said second pump and said outlet side of said duct for automatic maintenance of the same water level in said reservoir as in said column; said warm-water channel is provided with a level-maintaining device for maintaining a constant water level therein.
