AbstractAbstract
[en] Description is given of a separator-superheater apparatus comprising an outer enclosure containing a separating-unit and a steam superheating unit according to the main patent. The present addition relates to an improvement in that apparatus, characterized in that the separating unit and the superheating unit, mounted in two distinct portions of the outer enclosure, are divided into the same number of sub-units of each unit being identical and operating in parallel, and in that to each separator sub-unit is associated a superheater sub-unit, said sub-units being mounted in series and located in one in the other of the enclosure two portions, respectively. This can be applied to the treatment of the exhaust steam of a turbine high pressure body, prior to re-injecting said steam into the low pressure body

AbstractAbstract
[en] A drying system is described which allows for modular construction and which provides a significant available exchange area in a reduced volume. All the drying elements are identical and are distributed according to a ternay circular symmetry and are placed radially and associated to steam guiding facilities which alternately provide around the axis of revolution an output volume of dry steam from one element and an input volume of wet steam in the following element

AbstractAbstract
[en] The arrangement of a water separation device in the draught of several evaporator and superheater heating surfaces of a steam raising unit ensures sufficient cooling of the evaporator and superheater heating surfaces on firing the boiler, and also ensures a sufficiently high live steam temperature on part-load. The novelty lies in taking an additional line from the upper half of the water reservoir in parallel with the steam outlet into the penultimate evaporation stage. The return feedwater flow and the level set by this in the reservoir is adjusted by an adjustable valve in the return line, leaving the lower part of the separation and storage vessel. The control of the adjustable valve takes place in a control circuit using the quantity of water fed into the boiler and the superheater as measurement and control parameters. (HP) 891 HP/HP 892 MB

Die Anordnung einer Wasserabtrennvorrichtung im Zuge mehrerer Verdampfer- und Ueberhitzflaechen eines Dampferzeugers sichert beim Anfahren des Kessels ausreichende Kuehlung der Verdampfer- und Ueberhitzerheizflaechen und bei Teillast genuegend hohe Frischdampftempeartur. Neu ist es, eine zusaetzliche Leitung aus der oberen Haelfte des Wasserspeichers parallel zum Dampfauslass in die vorletzte Verdampferstufe zu fuehren. Durch ein Stellventil in der unten vom Trenn- und Speichergefaess abgehenden Rueckflussleitung wird die rueckfliessende Speisewassermenge und damit der sich im Speicher einstellende Pegel eingestellt. Die Steuerung des Stellventils erfolgt in einem Regelkreis mit den der in den Kessel eingespeiste Wassermenge und der Ueberhitzertemperatur als Mess- bzw. Stellgroessen. (HP)Original Title

AbstractAbstract
[en] The invention concerns a water separator for the condensation of humidity from steam of the inertia type, which has an improved flow distribution and can therefore be built for large dimensions. This is achieved by variation of the dimensions of the components of the liquid separator, particularly by the configuration of the drain trough, and by the fixing of suitable impact sheets, which produce turbulence and distribute the wet steam evenly over the separator elements. There is a detailed representation with drawings. (UW)

Die Erfindung betrifft einen Wasserabscheider fuer die Kondensation von Feuchtigkeit aus Dampf vom Inertialtyp, der eine verbesserte Stroemungsaufteilung besitzt und somit auch in groesseren Abmessungen gebaut werden kann. Man erreicht dies durch Variation der Abmessungen der Bauelemente des Fluessigkeitsabscheiders, insbesondere durch die Gestaltung des Abflusstroges und durch das Anbringen geeigneter Aufprallbleche, die Wirbel erzeugen und den feuchten Dampf gleichmaessig auf die Abscheiderelemente verteilen.

AbstractAbstract
[en] Prismatic sectional files, staggered one behind the other, enclose the tubes of the feedwater piping system. These sectional files of the steam moisture separator are dimensioned in such a way that the gaps between the individual rods of the files become tighter in the direction from the flowing - in steam towards the feedwater heater. With their lower end the sectional files are arranged on a plate with rim and water drain. By these measures there will be achived that the stagnation of the heating steam does not immediately affect the piping system. (DG)

Prismatische Profilreihen umschliessen hintereinander versetzt angeordnet die Rohre des Speisewasserrohrsystems. Diese Profilreihen des Dampfnaesseabscheiders sind so bemessen, dass die Spalte zwischen den einzelnen Stangen der Reihen in Richtung vom einstroemenden Dampf zum Speisewasservorwaermer hin enger werden. Die Profilreihen sind mit ihrem unteren Ende auf einer Platte mit Bordrand und Wasserablauf angeordnet. Durch diese Massnahmen wird erreicht, dass der Stau des Heizdampfes nicht unmittelbar auf das Rohrsystem einwirkt. (DG)Original Title

AbstractAbstract
[en] Up to now the operation of water-steam separators has been incompletely understood and difficult to pinpoint theoretically. The EDF Studies and Research department therefore undertook to build a test bed to reproduce the actual operating conditions of the separators. The most common types of apparatus were tested in collaboration with turbine manufacturers. The results make it possible to analyze their operation and to know their field of use. The tests were extended to develop high-speed separators, the size and efficiency of which allow extensive industrial development to be envisaged

Le fonctionnement des separateurs eau-vapeur etait jusqu'ici mal connu et difficile a cerner de facon theorique. La direction des etudes et recherches d'Electricite de France a donc entrepris la construction d'un banc d'essais destine a reproduire les conditions reelles de fonctionnement des separateurs. Les types d'appareils les plus repandus on ete testes en collaboration avec les constructeurs de turbines. Les resultats obtenus permettent d'analyser leur fonctionnement et de connaitre leur domaine d'utilisation. Les esais ont ete prolonges par la mise au point de separateurs a grandes vitesses de passage (S.G.V.) dont les dimensions et les performances permettent d'envisager un developpement industiel importantOriginal Title

AbstractAbstract
[en] An axial cyclone in the form of a spin generator with radial nozzles and a flow controller are installed directly in the overflow line between high and low pressure parts of a turbine. The water is centrifuged sideways via outlet slots into a water collecting chamber. The nozzles themselves are hollow and form the support for the flow controller. The extracted steam is taken via the nozzles to the flow controller and returned from this to the overflow line. (DG) 891 HP/DG 892 MB

Der abgesaugte Dampf wird ueber die Leitschaufeln dem Stroemungskoerper zugefuehrt und von diesenm in die Ueberstroemleitung zurueckgefuehrt. (DG)Original Title

AbstractAbstract
[en] The system described is stated to be of particular use in nuclear powered steam generating plant. The steam-water mixture is passed through pipes having apertures through which the mixture passes to a scrubber assembly. The separated steam leaving the scrubber assembly is passed through a perforated baffle. The apertures in the pipes and the perforations in the baffle are such as to produce a uniform velocity distribution through the steam and water mixture across the scrubber assembly. The separation is preferably performed in a vessel that can be used as a start-up vessel for the steam power generating boiler with which it is associated. (UK)

AbstractAbstract
[en] A steam generator separator is described consisting of two parts, i.e., axial and tangential. The tangential part is placed inside the axial part which, in turn, consists of an outer and an inner cylindrical jackets. The space between the two jackets forms a distribution chamber. Its top part joins up to the lattice of axial cylindrical vanes. Provided above them is a separation space with two collector chambers consisting of moulded sheets, bottom sheets and an annular lid closing the separation space. The collector chambers form tangential part inlet chambers with radial flat vanes and an outlet branch. The cylindrical jacket is common for both the axial and the tangential parts. The inlet ports of the steam-water mixture may be connected to the distribution chamber axially, radially or tangentially. (B.S.)
