摘要： Large scale field erected air cooled industrial steam condenser having heat exchanger panels independently loaded into and supported in a heat exchange frame section. A bottom bonnet runs along the bottom length of each heat exchanger panel for delivering steam to the bottom end of condenser tubes in the heat exchange panel and for receiving condensate formed in those same tubes. The tops of the tubes are connected to a top bonnet. Uncondensed steam and non-condensables are drawn into the top bonnet from the condenser tubes. A steam distribution manifold is suspended from the heat exchange section frame perpendicular to the longitudinal axis of the heat exchange panels and beneath a center point of the heat exchange panels and delivers steam to each heat exchange panel via a single steam inlet located at a center point of each bottom bonnet.

摘要： Modular flow control systems include several differently-shaped structures to achieve desired flow characteristics in fluid flow. Systems include one or many plates held in desired positions by a retainer within the flow. The plates are uniquely shaped based on their position, or vice versa, to shape flow in a desired manner. The plates may fill an entire flow area or may extend partially throughout the area. Plates can take on any shape and are useable in systems installed in any type of flow conduit. When used in a PCCS upper manifold in a nuclear reactor, a chevron plate directly below the inlet divides flow along the entire upper manifold. Perforated plates allow flow to pass at ends of the PCCS upper manifold. The plates can be installed along a grooved edge during an access period and held in static position by filling the length of the PCCS upper manifold.

摘要： A steam conditioning system for discharging bypass steam into a condenser of a steam powered generating plant and other uses. The system includes a steam conditioning device comprising an inner evaporative core and an outer shell. The core may be formed of a tubular piping section disposed at least partially inside the outer shell forming an annular space therebetween. An inlet end of the core receives steam from a piping header fluidly connected to an upstream desuperheating pressure reducing station which injects liquid coolant into the steam stream. Steam discharges through the core outlet end into the outer shell, reverses direction, and flows into the condenser. In one embodiment, the steam conditioning device may be disposed inside the dome of the condenser except for the inlet end. The device intends to increase flow residence time to evaporate entrained carryover coolant droplets in the incoming steam before release to the condenser.

摘要： A series-parallel condensing system comprised of an air-cooled condenser, a surface condenser, a circulating water system and a cooling tower, body of water, or other equivalent heat sink. The cooling tower, being an evaporative device, consumes water. In the simplest embodiment of the invention steam is condensed in a two-stage series process with steam first fed to an air-cooled condenser where the majority of the steam is condensed and then to a surface condenser, which in conjunction with the circulating water system and cooling tower condenses the remaining steam. This embodiment achieves the greatest degree of water conservation. The function of the surface condenser is to replace the dephlegmator of the air-cooled condenser, which results in a significant reduction in the size and cost of the air-cooled condenser and also yields improved plant performance and operational simplicity. In a second embodiment, where additional makeup water is available, a steam bypass system is added converting the system from a series condensing process into a series-parallel process. In this arrangement steam exiting the turbine flows through both the air-cooled condenser and also through the bypass system with final condensation taking place in the surface condenser.

摘要： An improved electrical-utility steam-turbine power-plant cooling system including a condenser with heat-exchange surfaces and cooling means. The cooling means has a closed-loop system with an intake, a discharge and a cooling portion. Substantially all of the cooling portion is tunneling beneath the surface of the Earth. Water substantially fills the closed-loop system and a pump facilitates flow through the closed-loop system whereby water flows through the tunneling and is geothermally cooled.

摘要： A Moisture Separator Reheater (MSR) has a plurality of tube bundles which receive high-pressure saturated (tubeside) steam therein. Steam to be reheated (shellside steam) is passed in heat-exchange relationship with the tubes of the first and second reheater tube bundles after first being dried by the panels of a moisture separator. It emerges from the shell of the reheater dried and heated. In the reheater tube bundles saturated steam at temperatures and pressures substantially higher than the shellside steam transfers heat to the shellside steam by condensation within the tubes. The steam in the second stage tube bundle is at a temperature and pressure that is substantially higher than that of the steam in the first stage tube bundle and is heating shellside steam at a higher temperature than the shellside inlet steam to the first stage tube bundle. A greater quantity of tubeside steam than is theoretically necessary is passed through the tube bundles. This excess steam causes scavenging of the tube bundle to substantially eliminate condensate subcooling and related instabilities. Scavenging steam is provided to the first stage tube bundle with essentially no thermodynamic loss by passing the exhausted scavenging steam from the second stage tube bundle through a high differential pressure (.DELTA.P) thermocompressor where it is isentropically expanded. It then entrains a higher rate of exhausted scavenging steam from the first stage tube bundle. The mixed discharge from the thermocompressor is then fed to the inlet of the first stage tube bundle, resulting in a high rate of scavenging steam therein. Minimal thermodynamic loss is achieved since the first stage scavenging steam is reused to continually scavenge the first stage tube bundle, rather than being exhausted to a lower energy point in the system, as is conventionally done, as for example to a feedwater heater.
