Description

Lufterhitzer in Großfeuerungsanlagen mit Wärmetauschgruppen im oberen Teil des Feuerraumes und im Abgasstrom Bekannt sind Lufterhitzer in Großfeuerungsanlagen mit im oberen Teil des Feuerraumes und im Abgasstrom befindlichen Wärmetauschgruppen. Bei solchen Anlagen ist es bekannt, zwischen den beiden Lufterhitzergruppen eine den Abgasstrom regulierende, hohl ausgebildete Umlenkklappe einzubauen.Air heater in large combustion systems with heat exchange groups in the upper Part of the combustion chamber and in the exhaust gas flow Air heaters in large combustion systems are known with heat exchange groups located in the upper part of the combustion chamber and in the exhaust gas flow. In such systems, it is known to have one between the two air heater groups to install the exhaust gas flow regulating, hollow deflector flap.

Aufgabe der Erfindung ist es nun, eine solche Umlenkklappe mehr, als es bisher möglich war, zur Lufterhitzung mit heranzuziehen, damit eine besonders hoch erhitzte Luft in möglichst großer Menge für Müll- bzw. Abfallverbrennungsanlagen zur Verfügung steht, wobei die Heißluft nicht nur zur Beschickung der verschiedenen Brennbettzonen des Feuerungsrostes, insbesondere Rückschubrostes, sondern auch zur möglichst weitgehenden Vortrocknung der zu verbrennenden AbfaHmasse dienen soll. Das Erreichen dieses Zieles wird durch die Erfindung dadurch unterstützt, daß eine zwischen den Wärmetauschgruppen eingebaute Umlenkklappe mit einer der beiden Wärmetauschgruppen durch eine Rohrverbindung parallelgeschaltet ist. Durch eine solche Parallelschaltung kann in jeder Stellung der Umlenkklappe eine der betreffenden Lufterhitzergruppe angepaßte, hohe Erhitzung der zur aktiven Lufterhitzung mit herangezogenen Umlenkklappe erzielt werden 3 da sie selbst zusätzlich Wärme aufnimmt. Außerdem trägt die Parallelschaltung zum besseren Hindurchleiten des Abgasstromes bei. Insgesamt begünstigt somit die Umlenkklappe gemäß der Erfindung das Arbeiten der Feuerungsanlage in einem besonders hohen Leistungsbereich.The object of the invention is to use such a deflector flap more than was previously possible for air heating, so that particularly high-temperature air is available in as large a quantity as possible for garbage or waste incineration plants, the hot air not only for charging the different combustion bed zones of the furnace grate, in particular the return grate, but also for the most extensive possible pre-drying of the waste material to be incinerated. Achieving this goal is supported by the invention in that a deflection flap installed between the heat exchange groups is connected in parallel with one of the two heat exchange groups by a pipe connection. By such a parallel circuit in each position of the flapper can matched one of the Lufterhitzergruppe concerned, high heating is achieved for the active air heating with relied flapper 3 since they themselves additionally absorbs heat. In addition, the parallel connection contributes to the better passage of the exhaust gas flow. Overall, the deflection flap according to the invention thus favors the operation of the combustion system in a particularly high power range.

Einzelheiten sind aus der nachstehenden Beschreibung sowie der Zeichnung ersichtlich. Letztere stellt vereinfacht eine Ausführungsform einer die Wärme nicht zur Dampferzeugung ausnützenden Großfeuerungsanlage dar, und zwar zeigt F i g. 1 einen Vertikalschnitt durch eine Großfeuerungs-(Abfallverbrennungs-)Anlage, F i g. 2 einen Horizontalschnitt.Details can be found in the following description and the drawing. The latter represents, in a simplified manner, an embodiment of a large combustion system that does not use the heat to generate steam, namely FIG. 1 shows a vertical section through a large combustion (waste incineration) plant, FIG. 2 a horizontal section.

Im oberen Teil des Feuerraumes 6 ist in bekannter Weise die Gruppe A der Lufterhitzerelemente 2 vorgesehen, die sich somit im, unmittelbaren Flammenbereich befinden. Der andere Teil des Lufterhitzers, nämlich die Gruppe B der Heizelemente, ist in ebenfalls bekannter Weise in einen oder mehrere der sich anschließenden Rauchgaszüge 7 eingebaut. Die Trennwand zwischen der Erhitzergruppe A und der Erhitzergruppe B wird durch ein Lufterhitzerelement 2a gebildet. Am übergang zwischen dem Feuerraum 6 und dem sich anschließenden Rauchgaszug 7 ist die Umlenkklappe 4 gelagert, die in der Schließstellung 4a bewirkt, daß die LufterhitzergruppeA mit dem gesamten Strom der Feuergase (Pfeile 8) beaufschlagt wird, wogegen in der gezeichneten Offen-Stellung 4 ein Teil der Feuergase in Pfeilrichtung 9 zum anschließenden Rauchgaszug 7 abströmt. Auf diese Weise hat man die Möglichkeit, den Grad der Lufterhitzung in der Erhitzergruppe A in bestimmten Grenzen zu regulieren. Die zur aktiven Lufterhitzung dienende, als Hohlkörper ausgebildete Klappe 4 kann einer der Wärinetauschgruppen A oder B parallelgeschaltet sein; im gezeichneten Ausführungsbeispiel (s. F i g. 2) ist die Klappe 4 durch die Rohrverbindung 5 mit der Wännetauschgruppe A parallelgeschaltet.In the upper part of the furnace 6 , the group A of the air heater elements 2 is provided in a known manner, which are thus located in the immediate flame area. The other part of the air heater, namely group B of the heating elements, is installed in one or more of the adjoining flue gas flues 7 in a likewise known manner. The partition between the heater group A and the heater group B is formed by an air heater element 2a. At the transition between the combustion chamber 6 and the adjoining flue gas flue 7 , the deflection flap 4 is mounted, which in the closed position 4a causes the air heater group A to be exposed to the entire flow of the flue gases (arrows 8) , whereas in the open position shown there is 4 Part of the fire gases flows off in the direction of arrow 9 to the subsequent flue gas flue 7 . In this way it is possible to regulate the degree of air heating in heater group A within certain limits. The valve 4, which is designed as a hollow body and is used for active air heating, can be connected in parallel to one of the heat exchange groups A or B; In the illustrated embodiment (see FIG. 2), the flap 4 is connected in parallel to the heat exchanger group A through the pipe connection 5.
