Description

Einrichtung zum gleichzeitigen Erwärmen von Luft und Speisewasser durch die Abgase von Kesselanlagen Es ist bekannt, in Kesselanlagen die Abgaswärme zum Vorwärmen von Speisewasser und Luft gleichzeitig zu verwenden. Es ist ferner bekannt, zur Übertragung der Wärme von den Abgasen auf die wärme-, aufnehmenden Mittel Wärmeübertragungsrohre zu verwenden, welche teilweise mit Flüssigkeit gefüllt sind und mit ihren unteren, flüssigkeitgefüllten Enden in den Strom der Abgase hineinreichen, so daß die in den Rohren befindliche Flüssigkeit verdampft und im oberen Teil der Rohre unter Abgabe der Verdampfungswärme an das andere Mittel wieder kondensiert.Device for simultaneous heating of air and feed water Through the exhaust gases from boiler systems It is known that the exhaust gas heat in boiler systems to be used to preheat feed water and air at the same time. It is further known to transfer the heat from the exhaust gases to the heat-absorbing Means to use heat transfer tubes, which are partially filled with liquid and their lower, liquid-filled ends extend into the flow of exhaust gases, so that the liquid in the tubes evaporates and in the upper part of the Pipes condensed again, releasing the heat of evaporation to the other means.

Die Erfindung betrifft eine Vorrichtung zum gleichzeitigen Erwärmen von Luft und Speisewasser durch die Abgaswärme von Kesselanlagen unter Verwendung der bekannten Wärmeübertragungsrohre. Die Erfindung besteht darin, daß die das Speisewasser führende Rohrschlange die in den Luftkanal hineinragenden, .nicht mit Flüssigkeit gefüllten Teile der geneigt angeordneten Wärmeübertragungsrohre durchsetzt, während die tiefer liegenden, die Flüssigkeit enthaltenden Teile derselben durch den Abgaskanal ge- führt sind. Hierdurch wird erreicht, daß die Speisewasserleitung von den heißesten Teilen der in den Wärmeübertragungsrohren befindlichen Flüssigkeitsdämpfen umgeben ist, so daß der größte Teil der in den Dämpfen enthaltenen Verdampfungswärme an das Speisewasser abgegeben wird, während die Luft, welche infolge ihrer geringeren spezifischen Wärme nur einen kleineren Teil der Verdampfungswärme zu ihrer Erhitzung benötigt, die oberen Teile der Wärmeübertragungsrohre nur von außen umstreicht. Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt.The invention relates to a device for the simultaneous heating of air and feed water by the exhaust gas heat from boiler systems using the known heat transfer tubes. The invention consists in that the feed water leading pipe coil which projects into the air duct, .not liquid filled parts of the angularly disposed heat transfer tubes passing through, while the deeper, containing parts of the liquid thereof are overall through the exhaust duct leads. This ensures that the feed water line is surrounded by the hottest parts of the liquid vapors located in the heat transfer tubes, so that most of the heat of evaporation contained in the vapors is given off to the feed water, while the air, which due to its lower specific heat, is only a smaller one Part of the heat of evaporation is required to heat it, the upper parts of the heat transfer tubes only stroked from the outside. An exemplary embodiment of the subject matter of the invention is shown in the drawing.

Das Heizgas strömt durch einen Kanal 3o von unten nach oben, das zu erwärmende Gas, beispielsweise kalte Luft, in einem parallel zum Kanal angeordneten, von ihm durch eine Stirnwand 36 getrennten Kanal qo im Gegenstrom, also von oben nach unten. Die Wärmeübertragung erfolgt durch eine Anzahl geneigter Rohre 16, die nur, soweit sie im Heizkanal 3o liegen, mit Flüssigkeit 18, etwa Wasser, gefüllt sind, während der aus der Flüssigkeit entwickelte Dampf sich nur in dem Teil der Rohre befindet, der im Kanal q.o für das zu erwärmende Gas liegt.The heating gas flows through a channel 3o from the bottom to the top warming gas, for example cold air, in a parallel to the duct, channel qo separated from it by an end wall 36 in countercurrent, that is from above downward. The heat transfer takes place through a number of inclined tubes 16, the only if they are in the heating channel 3o, filled with liquid 18, such as water are, while the vapor evolved from the liquid evolved only in that part of the Pipes is located, which is in the channel q.o for the gas to be heated.

Mit der Anlage ist ein Vorwärmer für Kesselspeisewasser o. dgl. verbunden, der durch den in den Rohren 16 gebildeten Dampf geheizt wird. Das Wasser strömt von der Leitung 42 durch den Dampfraum der Rohre 16 durchsetzende Schlangen q.¢ zu der darunterliegenden Leitung 46.A preheater for boiler feed water or the like is connected to the system, which is heated by the steam formed in the tubes 16. The water flows from the line 42 through the vapor space of the tubes 16 penetrating coils q. ¢ to the line 46 below.
