摘要： An induced draft air-cooled condenser for steam condensing applications includes a pair of inclined tube bundles defining a interior space therebetween in fluid communication with ambient air heated as it flows through the tube bundles. A fan supported above the interior space comprises rotatable fan blades disposed inside a cylindrical annular fan shroud. A drive mechanism operable to rotate the fan blades includes a motor operably coupled to the fan blades. The motor is supported inside the fan shroud and may be housed in a protective enclosure which may be insulated. A motor cooling system includes an air inlet duct fluidly coupled to ambient air outside the shroud and the enclosure. When the fan operates, cool ambient air is drawn via a vacuum formed by the fan through the duct to cool the motor. The air thus bypasses and is not heated by the tube bundles.

摘要： An air cooled steam condenser having heat exchanger panels 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 located below the heat exchange section perpendicular to the longitudinal axis 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： 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 heat dissipation system apparatus and method of operation using hygroscopic working fluid for use in a wide variety of environments for absorbed water in the hygroscopic working fluid to be released to minimize water consumption in the heat dissipation system apparatus for effective cooling in environments having little available water for use in cooling systems. The system comprises a low-volatility, hygroscopic working fluid to reject thermal energy directly to ambient air. The low-volatility and hygroscopic nature of the working fluid prevents complete evaporation of the fluid and a net consumption of water for cooling, and direct-contact heat exchange allows for the creation of large interfacial surface areas for effective heat transfer. Specific methods of operation prevent the crystallization of the desiccant from the hygrosopic working fluid under various environmental conditions.

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： 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.
