Description

k-auchgasvorwärmer für Luft und Wasser Die Erfindung bezieht sich auf einen Rauchgasvorwärmer für Luft und Wasser. Bei derartigen Einrichtungen ist (es bereits bekannt, die Rauchgasleitungen derart umschaltbar ieinzurichten, daß die Rauchgase je nach der Kesselbelastung entweder zuerst in den Wasservorwärmer und dann den Luftvorwärmer oder aber beide Vorwärmet ganz oder teil weise oder auch in umgekehrter Folge durchströmen.k-also gas preheater for air and water The invention relates on a flue gas preheater for air and water. With such facilities is (It is already known that the flue gas pipes can be switched over in such a way that the flue gases either first into the water preheater, depending on the boiler load and then the air preheater or both preheaters in whole or in part or also flow through in reverse order.

Demgegenüber ermöglicht der vorliegende Rauchgasvorwärmer,einen stufenweisenWärmeaustausch dadurch, daß der eine Vorwärmet, z.. B. der für Luft, in zwei Teile zerlegt ist, die an den Enden eines - gebogenen Kanals für die Rauchgase liegen und beide Teile durch eine gerade Leitung verbunden sind, während der andere Vorwärmet, z. B. der für NVasser, in den gebogenen Kanal zwischen den beiden genannten Vorwärmerteilen angeordnet ist.In contrast, the present flue gas preheater enables a gradual heat exchange in that one of the preheaters, e.g. the one for air, is divided into two parts, which are at the ends of a - curved duct for the flue gases and both parts are connected by a straight line, while the other preheat, e.g. B. the for NVasser, in the curved duct between the two preheater parts mentioned is arranged.

Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise in einem lotrechten Schnitt veranschaulicht.In the drawing, for example, the subject matter of the invention is in one perpendicular section illustrated.

Die auszunutzenden Rauchgase gelangen auf ihrem Wege zum Schornstein in Richtung der Pfeile i durch den Hilfskanal z, in dessen parallelen Enden die Teile 3 und 4 des Luftvorwärmers eingeschaltet sind. Zwischen diesen Teilen, also in dem Mittelteil des Hilfskanals, ist dagegen der Sp.eisewasservonvärmer 5 @mingebaut, dem somit die erst- teilweise ausgenutzten Rauchgase noch genügend heiß zuströmen, damit ihm ein guter Wirkungsgrad gesichert ist. Das Wasser durchfließt den Vorwärmet 5 zweckmäßig in Richtung der ,eingezeichneten Pfeile 6 im Gegenstrom zu den Heizgasen.The flue gases to be exploited reach the chimney on their way in the direction of the arrows i through the auxiliary channel z, in whose parallel ends the Parts 3 and 4 of the air preheater are switched on. Between these parts, so In the middle part of the auxiliary canal, on the other hand, the Sp.eisewasservonvärmer 5 @ming is built, to which the flue gases, which have been partially used up, still flow in sufficiently hot, so that he is assured of a good level of efficiency. The water flows through the preheater 5 expediently in the direction of the arrows 6 shown in countercurrent to the heating gases.

Diie Wärmeaustauschkörper des Luftvorwärmers sind so hintereinandergeschaltet, daß sie durch .eine gerade Leitung 7 verbunden werden können, damit ein gerader Durchgang für die zu erwärmende Luft in Richtung der Pfeile 8 gewährleistet ist.The heat exchange bodies of the air preheater are connected in series so that that they can be connected by a straight line 7, so that a straight line Passage for the air to be heated in the direction of the arrows 8 is guaranteed.
