摘要： The invention relates to a heat exchanger arrangement having at least one multipass heat exchanger, which comprises a first distributor (1), a second distributor (2) and at least one tubular diverter distributor (4) having a predefined tube cross-section (AU), and a tube arrangement (25) having a plurality of tubes (5) which are at least substantially parallel to one another and have a predefined tube cross-section (AR), through which a fluid—particularly, water—can flow and which are arranged in the tube arrangement (25) in columns with a predefined number of columns (n), wherein the first distributor (1) and the second distributor (2) are arranged at one end (A) of the heat exchanger arrangement and the diverter distributor (4) is arranged at the opposing end (B), and the tubes (5) extend from the one end (A) to the opposing end (B) and are connected to the diverter distributor (4) and the first or the second distributor (1, 2), and at least one vent opening (10) is arranged at a highest point (T), or at least in the vicinity of the highest point (T), of the diverter distributor (4) to equalize the pressure with the surroundings. In order to enable rapid filling of the heat exchanger arrangement with the fluid, a valve (11) is arranged in the at least one vent opening (10). When the valve (11) is fully opened, a flow cross-section (d) is clear for the passage of air, and the pipe cross-section (AU) of the diverter distributor (4) and the flow cross-section (d) of the valve (11) are the same as or greater than a minimum cross-section (Dmin), which is calculated from the product of the number of columns in the tube arrangement (25) and the pipe cross-section (AR) of the tubes (Dmin=n AR).

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 passive containment cooling system (PCCS) condenser, for reducing some non-condensable gases in the PCCS, includes a first and a second stage condenser that each include channels in fluid communication between an inlet and an outlet header. The inlet header of the first stage condenser is configured to receive a fluid mixture through a first inlet opening. The channels are configured to condense water from the fluid mixture flowing through the channels from the inlet header to the outlet header, respectively, of the first and second stage condenser. The PCCS condenser includes a catalyst in at least one of the outlet header of the first stage condenser or the inlet header of the second stage condenser. The catalyst catalyzes a reaction for forming water from hydrogen and oxygen in the fluid mixture. The outlet header of the second stage condenser is in fluid communication with a combined vent-and-drain line.

摘要： A dual fluid heat exchange system is presented that provides a stable output temperature for a heated fluid while minimizing the output temperature of a cooled fluid. The heated and cooled fluids are brought into thermal contact with each other within a tank. The output temperature of the warmed fluid is maintained at a stable temperature by a re-circulation loop that connects directly to the mid portion of the tank such that the re-circulated fluid flow primarily warms only a re-circulation section of the tank. The other, lower flow rate, section of the tank may be positioned so that it has a cooler temperature and thus serves to increase the efficiency of the heat exchange by extracting extra heat energy out of the cooled fluid before it leaves the tank. Alternatively, the low flow rate section of the tank may be warmer than the re-circulated section, and thus allow the re-circulated section to be cooler than the output temperature of the warmed fluid.

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： An air-cooled condensing heat exchanger system (“ACHX”) installed in a fossil power plant flue gas treatment system recovers water and low temperature waste heat from boiler flue gas for advanced coal fired power plant applications. More particularly, the ACHX system recovers water from combustion flue gas by phase change. To recover water from flue gas, the ACHX system uses ambient air from an air intake installed on the stack to cool down the flue gas in the ACHX.

摘要： A wick liquid sensor suitable for use in a particle condensation device is provided. The sensor includes a light source configured to illuminate a surface of the wick. A detector is configured to detect wick reflected light from the light source and determine the intensity of reflected light. The wick is formed from a porous media that is wettable by the liquid, and becomes translucent when filled with the liquid. The amount of reflectivity decreases as the saturation content of the liquid in the wick increases.
