Abstract: An air cooled condenser apparatus has a tubular shell having an open upper end and an open lower end, a ring of tube bundle panels disposed generally vertically and at an angle to each other, with each of the tube bundles comprising a primary condenser region and a secondary condenser region, and adapted for air flow therethrough to condense fluid in the panels, and configured so that air flow through the panels passes through and exits the open upper end of the shell, and a duct disposed at the ground level of the shell, and a non-condensable extraction system with active or passive devices to control the local rate of the evacuated mixture of non-condensables and attached steam.

Abstract: The present invention relates to a duct for conducting a flowing primary fluid, having a thermally conductive wall with exterior ribs having an exterior side through which a secondary fluid can pass, at least partially, whereby the duct wall comprises a structured surface on its exterior side in addition to the ribs. The invention further relates to a heat exchanger with an inventive duct and an air condenser, particularly a natural-draught condenser, with inventive heat exchangers.

Abstract: The invention relates to methods and devices for directing the flow of air in the suction area formed by the chamber below air-cooled condenser systems that are mounted on support structures and are comprised of air-cooled condensation installations consisting mainly of one vertical plane with air flowing through and of a plane consisting of condenser modules with cooling elements, designed for cooling process and turbine exhaust. In order to prevent the disrupting influences caused by crosswinds, according to the invention, wind deflection panels can be installed in the area of the air intake nozzles and/or near the floor underneath the air-cooled condenser system. The wind deflection panels according to the invention can be installed such that they are static or movable, made of steel construction, or made of other suitable materials, such as canvas, plastic, or wood. If the wind deflection panels are movable, an automatic or manual adjustment to current wind conditions is possible.

Abstract: A natural draft cooling tower for condensing turbine steam of a power plant is comprised of identical sectors assembled to form the cooling tower. A central steam inlet line terminates in radial distributing lines. Each sector has one of the radial distributing lines. Each sector has first heat exchanger elements operating in a condensational manner and second heat exchanger elements operating in a dephlegmational manner, with the second heat exchanger elements arranged downstream of the first heat exchanger elements. The second heat exchanger elements are each provided with a fan. Each sector has an inert gas line connected to the second heat exchanger elements and a condensate removal line connected to the first and the second heat exchangers. Each sector further comprises an independent support frame for supporting the first and the second heat exchanger elements.

Abstract: A method for producing heat exchange elements having a tubular base body with ribs connected to the outer surface area for increasing the heat exchange surface area are especially suitable for base bodies having a cross-section with a width that is substantially greater than its height. According to the method, the ribs are produced by removing sheet metal strips from a roll and passing them through a corrugating device, positioning the corrugated sheet metal strips on lateral surfaces of the base body and welding the corrugated sheet metal strips to the base body. The application of the corrugated sheet metal strips, their positioning relative to the base body, and the transport of the base body in its longitudinal direction are effected by a special drive unit. For welding the sheet metal strips to the base body, laser heads are preferably used.
