Description
Wärmeaustauschvorrichtung, insbesondere zum Vorwärmen von Speisewasser durch Heizgase mit quer zur Richtung des Heizgasstromes liegenden Flossenrohren Die Erfindung bezieht sich auf Wärmeaustauschvorrichtungen, insbesondere auf solche zum Vorwärmen von Speisewasser durch Heizgase, wobei die quer zur Richtung des Heizgases liegenden Rohre des Vorwärmers mit Längsflossen versehen sind. Die Erfindung besteht darin, daß die Flossenrohre so angeordnet sind, daß die Flossen der hintereinanderliegenden Rohre geschlossene parallele Kanäle für den Durchzug der Heizgase bilden.Heat exchange device, in particular for preheating feed water by heating gases with finned tubes lying transversely to the direction of the heating gas flow The invention relates to heat exchange devices, in particular to such for preheating of feed water by heating gases, the transverse to the direction of the heating gas lying pipes of the preheater are provided with longitudinal fins. The invention exists in that the fin tubes are arranged so that the fins of the one behind the other Pipes form closed parallel channels for the passage of the heating gases.
Der Gegenstand der Erfindung ist in der Zeichnung beispielsweise dargestellt; in der Zeichnung zeigt Abb. i die Seitenansicht eines Rauchgasvorwärmers, Abb. 2 die Vorderansicht, Abb. 3 einen Querschnitt durch die Rohre. Der in dem Abgaskanal A liegende Vorwärmer B besteht aus mehreren Reihen von wagerecht angeordneten Rohren 7, wobei die Rohre aufeinanderfolgender Reihen gegeneinander versetzt sind. Die oberste Rohrreihe ist mit einer Leitung 8 verbunden, durch welche das zu erwärmende Wasser zuströmt und dann unter Vermittlung der Verbindungsstücke g die Rohre von oben nach unten nacheinander durchfließt, um schließlich den Vorwärmer durch das Auslaßrohr =o zu verlassen. Die Rohre 7 sind oben und unten mit Flossen =i versehen, wobei die jeweils in einer senkrechten Ebene liegenden Rohre mit ihren Flossen geschlossene parallele Kanäle für die Heizgase bilden. Die Heizgase sind gezwungen, die durch die Flossen gebildeten Kanäle mit ziemlich hoher Geschwindigkeit zu durchströmen, wobei sie wechselweise von Rohr zu Rohr abgelenkt werden. Hierdurch findet ein kräftiges Bestreichen der Rohre und Flossen statt, wodurch die Wärmeübertragung verbessert und die Ablagerung von Flugasche verringert wird.The object of the invention is shown in the drawing, for example; In the drawing, Fig. i shows the side view of a flue gas preheater, Fig. 2 the front view, Fig. 3 a cross section through the tubes. The one in the exhaust duct A horizontal preheater B consists of several rows of horizontally arranged pipes 7, the tubes of successive rows being offset from one another. the top row of tubes is connected to a line 8 through which the to be heated Water flows in and then, with the intermediation of the connecting pieces g, the pipes of flows through one after the other from top to bottom to finally pass through the preheater Outlet pipe = o to leave. The tubes 7 are provided with fins = i at the top and bottom, the tubes each lying in a vertical plane with their fins closed Form parallel channels for the heating gases. The heating gases are forced through to flow through the channels formed by the fins at a fairly high speed, alternately deflecting them from tube to tube. This creates a strong Brush the tubes and fins instead, which improves heat transfer and the deposition of fly ash is reduced.
Die Verbindungsstücke g werden am vorteilhaftesten außerhalb des Abgaskanals verlegt, wie dies in. Abb. i gezeigt ist, so daß sie zum Zwecke der Reinigung leichter entfernt werden können.The connecting pieces g are most advantageously outside the exhaust duct relocated as shown in. Fig. i, making them easier for cleaning purposes can be removed.
