摘要： A large scale field erected air cooled industrial steam condenser. A bottom bonnet runs along the bottom length of the heat exchanger bundle for delivering steam to the bottom end of the condenser tubes 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 flow into the top bonnet from the condenser tubes. Each cell of the ACC is fed by steam distribution manifold suspended from and directly below the bundle support framework.

摘要： A vapor/liquid condensation system includes a condensation unit and an evaporation unit. The condensation unit is connected with the evaporation unit via conduits. The evaporation unit has a liquid inlet, a vapor outlet and an evaporation chamber in communication with each other. The evaporation unit converts liquid-phase working fluid into vapor-phase working fluid, which spreads to the condensation unit. The condensation unit cools and condenses the vapor-phase working fluid into liquid-phase working fluid, which goes back the evaporation unit. After the vapor-phase working fluid enters the condensation unit, the vapor-phase working fluid is distributed and condensed into liquid-phase working fluid. Then the liquid-phase working fluid is collected and then goes back to the evaporation unit. The length of the pipeline is shortened and the pipeline pressure is lowered to avoid interruption of heat dissipation circulation and failure in heat dissipation.

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 plurality of heat transfer pipes; a first header and a second header to which both ends of each of the heat transfer pipes that are disposed in parallel are fixed, respectively; a plurality of plate-shaped fins through which each of the heat transfer pipes is penetrated and that are provided at intervals in a direction in which the heat transfer pipes extend between the first header and the second header; and a fan that circulates an airflow between the plate-shaped fins are included. The first header and the second header are formed to be sectioned into multiple rows, the heat transfer pipes are disposed densely in an sectioned area of the first header and the second header, and the heat transfer pipes are disposed sparsely in an area between the sectioned areas of the first header and the second header.

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.
