摘要:
In a method for degassing make-up water for a water-steam-circuit of a steam turbine process make-up water is introduced at a location of introduction into an exhaust steam pipe of the steam turbine so as to form a water film. A connector of the exhaust steam pipe is positioned in the vicinity of the location of introduction and connected to an evacuating device. The gases released from the make-up water are removed via the connector and the evacuating device. The device for performing the method has an exhaust steam pipe with an inner wall and free ends. At least one overflow trough including a deflecting shield is connected to the inner wall of the exhaust steam pipe. Closure plates are connected to the free ends of the exhaust steam pipe. The deflecting shield, the closure plates, the inner wall, and the overflow trough delimit a chamber having an opening toward the interior of the exhaust steam pipe only at the lower free edge of the deflecting shield.

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. The first heat exchanger elements are connected to the support frame such that their longitudinal axis is perpendicular to the radial distributing line and extends in a plane parallel to the radial plane of the radial distributing lines.

A natural-draft cooling tower having a plurality of preferably roof-shaped heat exchange elements for condensing the turbine exhaust steam from a power plant. A portion of the heat exchange elements are connected to operate as condensers, and another portion of the heat exchange elements are connected to operate as dephlegmators, reflux condensers or fractionating columns, with the latter being disposed downstream, when viewed in the direction of flow of the steam, of the heat exchange elements that operate as condensers. In order to assure a complete condensation, and a residual condensation in the heat exchange elements that operate as reflux condensers, under all weather and load conditions, the heat exchange elements that operate as reflux condensers are each provided with a respective fan, the conveying capacity of which can be regulated.

摘要:
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.
