Description
Luftvorwärmer zum Vorwärmen der Verbrennunqsluft für Wasserrohrkessel Die Erfindung bezieht sich auf einen Luftvorwärmer zum Vorwärmen der Verbrennungsluft für Wasserrohrkessel mit den Feuerraum seitlich begrenzenden Wasserrohren und in Richtung der Rostbahn liegender Obertrommel.Air preheater for preheating the combustion air for water tube boilers The invention relates to an air preheater for preheating the combustion air for water tube boilers with water tubes laterally delimiting the combustion chamber and in Direction of the grate track lying upper drum.
Die Erfindung besteht darin, daß die Vorwärmerrohre mit Abstand und parallel zueinander angeordnet und in einen oberen Sammler und einen unteren, auf dem Kesselfundament aufliegenden Sammler zu Rohrwänden zusammengefaßt, das die Kesseltrommel tragende Kesselgerüst bilden.The invention consists in that the preheater pipes with distance and arranged parallel to each other and in an upper collector and a lower one The collector lying on the boiler foundation is combined to form pipe walls that form the boiler drum Form the load-bearing boiler frame.
Es ist bekannt, die der Abstrahlung an die umgebende Atmosphäre unterliegenden Teile eines Kessels durch einen besonderen Luftmantel zu isolieren. Die den Luftmantel bildende Luft wird durch einen Zwischenraum hindurchgeführt, der durch eine den Kessel mit Abstand umgebende Verkleidung gebildet wird, bevor sie in den eigentlichen Vorwärmer, z. B. aus Rohren, gelangt.It is known that those are subject to radiation to the surrounding atmosphere To insulate parts of a boiler with a special air jacket. The air jacket forming air is passed through a space through one of the Boiler with spaced surrounding cladding is formed before moving into the actual Preheater, e.g. B. from pipes.
Der Vorteil der Ausbildung gemäß der Erfindung dem Bekannten gegenüber wird darin gesehen, daß das übliche, für die Bildung der Kesselseitenwände und zum Tragen der Kesseltrommel erforderliche Kesselgerfst in Fortfall kommt und durch die Rohre des Luftvorwärmers gebildet wird.The advantage of the training according to the invention over the known is seen in the fact that the usual for the formation of the boiler side walls and for The boiler frame required to carry the boiler drum comes and goes through the tubes of the air preheater is formed.
Diese besondere Ausbildung gestattet es in gleicher Weise wie beim Vorhandensein eines normalen Kesselgerüstes, die die Feuerraumseitenwände bildenden Wasserrohre des Kessels an der Kesseltrommel ohne untere Auflagerung der unteren Verteiler der Feuerraumseitenwandrohre aufzuhängen.This special training allows it in the same way as with Presence of a normal boiler frame that forms the furnace side walls Water pipes of the boiler on the boiler drum without lower support of the lower Suspend the distributor of the combustion chamber side wall pipes.
Die Zeichnung stellt ein Ausführungsbeispiel des Gegenstandes der Erfindung dar, und zwar zeigt Fig. 1 einen Querschnitt durch den Kessel mit durch den Luftvorwärmer gebildetem Kesselgerüst, bei dem die Verbrennungsluft durch die Vorwärmerrohre gesaugt wird, Fig. 2 einen Querschnitt durch den Kessel mit durch den Luftvorwärmer gebildetem Kesselgerüst, bei dem die Verbrennungsluft durch die Vorwärmerrohre gedrückt wird, und Fig. 3 eine Seitenansicht des Kessels mit teilweise entfernter Seitenabdeckung.The drawing represents an embodiment of the subject matter of Invention, namely Fig. 1 shows a cross section through the boiler with through the air preheater formed boiler frame, in which the combustion air through the Preheater pipes is sucked, Fig. 2 shows a cross section through the boiler with through the air preheater formed boiler frame, in which the combustion air through the Preheater tubes is pressed, and Fig. 3 is a side view of the boiler with partially removed side cover.
Der L uftvorwärmer 1 besteht aus den senkrecht angeordneten Vorwärmerrohren 2, die zur Bildung von Rohrwänden an ihren oberen und unteren Enden zusammengefaßt sind. Die Vorwärmerrohre 2 sind an ihren unteren Enden in dem Sammler 3 zusammengefaßt und mit Abstand nebeneinander angeordnet. Die oberen Enden der Vorwärmerrohre 2 sind entweder in dem offenen Profil 4 (Fig. 1) oder in dem Sammler 5 (Fig. 2 und 3) befestigt, je nachdem, ob die Verbrennungsluft durch den Luftvorwärmer 1 angesaugt oder gedrückt werden soll. Zwei der auf diese Weise gebildeten Rohrwände werden zu beiden Seiten des Feuerraumes 6 stehend angeordnet, und zwar liegen die unteren Sammler 3 auf dem Kesselfundament 7 auf. Die oberen Profile 4 oder Sammler 5 der Rohrwände sind durch die Traversen 8 miteinander verbunden. Auf diese Weise wird das Kesselgerüst durch den Luftvorwärmer 1 gebildet. Die Traversen 8 tragen die Kesseltrommel 9. Von der Kesseltrommel 9 gehen die die Seitenwände des Feuerraumes 6 bildenden Wasserrohre 10 aus, die an ihren unteren Enden in den Verteilern 11 zusammengefaßt sind. Der Raum zwischen den den Feuerraum 6 umschließenden Wasserrohren 10 und den Rohrwänden, aus denen der Luftvorwärmer 1 besteht, ist durch Isoliermaterial 15 ausgefüllt. Außen sind die Rohrwände des Luftvorwärmers 1 zur Bildung von glatten Außenwänden durch eine Blechverkleidung 14 od. dgl. abgedeckt.The air preheater 1 consists of the vertically arranged preheater tubes 2, which are combined to form tube walls at their upper and lower ends. The preheater tubes 2 are combined at their lower ends in the collector 3 and arranged at a distance from one another. The upper ends of the preheater tubes 2 are either fastened in the open profile 4 (FIG. 1) or in the collector 5 (FIGS. 2 and 3), depending on whether the combustion air is to be sucked in or pushed through the air preheater 1. Two of the pipe walls formed in this way are arranged upright on both sides of the combustion chamber 6, specifically the lower collectors 3 rest on the boiler foundation 7. The upper profiles 4 or collectors 5 of the pipe walls are connected to one another by the cross members 8. In this way, the boiler frame is formed by the air preheater 1. The cross members 8 carry the boiler drum 9. The water pipes 10 forming the side walls of the furnace 6 extend from the boiler drum 9 and are combined at their lower ends in the distributors 11. The space between the water pipes 10 surrounding the furnace 6 and the pipe walls from which the air preheater 1 consists is filled with insulating material 15. On the outside, the pipe walls of the air preheater 1 are covered by sheet metal cladding 14 or the like to form smooth outer walls.
Die vorzuwärmende Verbrennungsluft wird, wie es in Fig. 1 gezeigt ist, mittels eines Gebläses 12 durch die Vorwärmerrohre 2 hindurchgesaugt und dem Rost 13 zugeführt. Bei der Ausführung nach Fig. 2 und 3 wird die Verbrennungsluft von einem Gebläse 12 von oben über die Sammler 5, die Vorwärmerrohre 2 und die Sammler 3 zum Rost 13 gedrückt. Der Verlauf der Verbrennungsluft ist durch Pfeile angedeutet.The combustion air to be preheated is as shown in FIG is, sucked through the preheater tubes 2 by means of a fan 12 and the Grate 13 supplied. In the embodiment according to FIGS. 2 and 3, the combustion air is by a fan 12 from above via the collector 5, the preheater pipes 2 and the collector 3 pressed towards grate 13. The course of the combustion air is indicated by arrows.
Die Durchführung von gegebenenfalls an den Wasserrohren 10 des Kessels erforderlich werdenden Instandssetzungsarbeiten ist ohne Schwierigkeit durchzuführen. Es ist hierzu nur erforderlich, die Blechverkleidung 14 abzunehmen und zwischen den Vorwärmerrohren 2 der Rohrwände des Luftvorwärmers 1, an der Stelle, an der sich die Schadensstelle befindet, die Isolierung 15 zu entfernen, so daß die Wasserrohre 10 freigelegt werden.The implementation of, if necessary, on the water pipes 10 of the boiler Any repair work that becomes necessary can be carried out without difficulty. It is only necessary to remove the sheet metal cladding 14 and between the preheater tubes 2 of the tube walls of the air preheater 1, at the Remove the insulation 15 from the point at which the damaged area is located, so that the water pipes 10 are exposed.
