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 method for removing condensate from a steam line during a cold startup is provided, including introducing a dip tube in a substantially vertical orientation within a substantially vertical section of a steam line, wherein the dip tube includes a proximal end and a distil end, immersing the distil end within a volume of condensate, connecting the proximal end to a removal conduit external to the steam line, and removing at least a portion of the condensate through the removal conduit.

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.

摘要： A new heat exchange tube fin design in which a plurality of arrowhead shapes are pressed into or embossed onto each fin, the arrowhead shape defined by two intersecting wedge sections. The pressed arrowhead shapes are grouped into nested pairs, and one of the arrowheads in a pair is pressed as a positive relative to the fin plane and the other of the pair is pressed as a negative relative to the fin plane. The arrowhead pairs are placed in rows parallel to the air flow direction and arrowhead pairs in one row are preferably staggered relative to the arrowhead pairs in the adjacent row along the fin in the air flow direction.

摘要： Helically coiled heat exchanger for the indirect exchange of heat between a two-phase first medium and a second medium has a shell surrounding a shell space, which extends along a longitudinal axis, an inlet for the admission of the two-phase first medium into the shell space, a tube bundle arranged in the shell space and having multiple helically coiled tubes for accommodating the second medium and a separating device for separating a gaseous phase from a liquid phase. The separating device has a tray arranged above the tube bundle which serves for collecting the liquid phase. The tray has a plurality of chimneys for separating the two phases. Each chimney projects from the tray from a side of the tray facing away from the tube bundle and is covered by a roof. An opening in the tray between the roof and an upper end of the respective chimney, there is provided an inlet opening via which the gaseous phase can flow into the respective chimney.

摘要： The heat exchange system is for heating water from a water source and comprises first and second flooded heat exchangers that have steam sides that are each independently fed with steam, but water sides that are serially fed with water through the first heat exchanger then through the second heat exchanger. The system also comprises first and second control valves located at or downstream of subcooled condensate outlets of the first and second heat exchangers, first and second water temperature sensors at or downstream of the heated water outlets of the first and second heat exchangers, and a control device for receiving temperature data from the first and second water temperature sensors and for controlling the first and second control valves. The proportions of the first and second steam sides that are flooded are respectively selectively adjusted by controlling the debit of condensate allowed through the first and second subcooled condensate outlets with the first and second control valves, for allowing heat exchange to the water to be adjusted as a result of the water temperature measured by the first and second water temperature sensors. The first and second control valves are set in one of a first state in which they are both at least partly opened to allow effective heat exchange from the steam to the water in both first and second heat exchangers, and a second state in which one of them is closed while the other is at least partly opened to have an effective heat exchange from the steam to the water in only one of the first or second heat exchangers while the first and second steam sides remain both supplied with steam.

摘要： The present invention relates to a V-shaped heat exchanger for condensing exhaust steam from a turbine. The V-shaped heat exchanger comprises primary, secondary and tertiary single-row condensing tubes placed in a V-shaped geometry. A steam supply manifold supplies the exhaust steam to lower ends of the primary tubes and steam that is not condensed in the primary tubes is collected at upper ends of the primary tubes and transported to the secondary tubes using top connecting manifolds. Steam that is not condensed in the secondary tubes is further transported to the tertiary tubes using a bottom connection manifold. The tertiary tubes are coupled at their ends with an evacuation manifold for evacuating non-condensable gases.
