von Dampfkesselanlagen.of steam boiler systems.
Bei einer Reihe von Dampfkesselanlagen, wo nur ein Teil des Dampfes zur Erzeugung von Maschinenkraft verwendet wird, ist es oft mit Schwierigkeiten verbunden, die Wärme in demselben Umfange wie bei Niederdruckanlagen, die nur für Heiz- und Kochzwecke konstruiert sind, auszunutzen.In a number of steam boiler systems where only part of the steam is used to generate it When used by machine power, it is often difficult to get the heat to the same extent as with low-pressure systems that are only used for heating and cooking purposes are designed to take advantage of them.
Die Kesseltemperatur ist höher und die entsprechende Temperatur der Rauchgase muß wenigstens ebensoviel höher, gewöhnlich wesentlich höher sein.The boiler temperature is higher and the corresponding temperature of the flue gases must be at least as much higher, usually much higher.
Um diese größere abziehende Wärme bei Hochdruckdampfanlagen von der erwähnten Art in demselben Umfange wie bei Niederdruckdampf anlagen auszunutzen, ohne den Kesseldruck zu verkleinern, wird nach dem Verfahren der vorliegenden Erfindung der Dampfdruck und dabei die Temperatur der von dem Speisewasservorwärmer kommenden Mischung von Dampf und Verdichtungswasser herabgesetzt, bevor diese Mischung in bekannter Weise durch ein im Rauchkanal angebrachtes Rohrsystem durchgeleitet wird, in welchem das Verdichtungswasser unter· Benutzung eines Teiles der im Rauche abziehenden Wärme wieder verdampft.In order to remove this greater amount of heat in high-pressure steam systems of the type mentioned to the same extent as with low-pressure steam systems, without using the boiler pressure to decrease, according to the method of the present invention, the vapor pressure and thereby reducing the temperature of the mixture of steam and compression water coming from the feed water preheater, before this mixture is passed in a known manner through a pipe system installed in the smoke channel, in which the compression water using part of the heat extracted in the smoke evaporated again.
Das Verfahren wird in folgender Weise ausgeführt :The procedure is carried out in the following manner :
Ein Teil des Dampfes, der zum Heizen oder Kochen benutzt wird, passiert zuerst einen Speisewasservorwärmer, wodurch ein Teil des Dampfes unter Erwärmung des Speisewassers verdichtet wird. Die Mischung von Dampf und Verdichtungswasser passiert nun eine zur Druckreduzierung dienende Vorrichtung, in welcher der Druck und dabei die Temperatur der Mischung herabgesetzt wird. Die Mischung wird schließlich durch ein im Rauchkanal angebrachtes Rohrsystem geleitet, wo das Verdichtungswasser unter Benutzung eines Teiles der im Rauche abziehenden Wärme wieder verdampft. Wegen der durch die Druckreduzierung hervorgebrachten niedrigeren Temperatur ist es möglich, die Wärme des Rauches in demselben Maße auszunutzen wie bei Niederdruckdampfanlagen und dazu noch den hohen Kesseldruck zu erhalten. Außerdem wird das von dem Dampfstrome mitgerissene Wasser die Wandungen des Rohrsystems benetzen, so daß dieselben mit einer Schicht von kochendem Wasser überzogen werden, wodurch die möglichst besten Wärmedurchgangsverhältnisse erreicht werden. Die Vorrichtpng ergibt die bestmöglichsten Konstruktionsverhältnisse , nämlich einen möglichst großen Temperaturunterschied, sowohl bei Vorwärmung des Speisewassers als auch bei Wiederverdampfung des Verdichtüngswassers.Some of the steam used for heating or cooking passes through you first Feed water preheater, whereby part of the steam is heated by heating the feed water is compressed. The mixture of steam and compression water now passes through a Pressure reducing device in which the pressure and thereby the temperature the mixture is reduced. The mixture is finally placed in the smoke channel through a Pipe system, where the compression water using part of the heat extracted in the smoke again evaporates. Because of the lower temperature brought about by the pressure reduction it is possible to use the heat of the smoke to the same extent as with low-pressure steam systems and to maintain the high boiler pressure. In addition, that which is carried away by the steam flow Water wet the walls of the pipe system, so that the same with a layer be covered by boiling water, creating the best possible heat transfer ratios can be achieved. The Vorrichtpng results in the best possible construction conditions , namely as large a temperature difference as possible, both when preheating the feed water and when re-evaporation of the compression water.
