Description

Plattenlufterhitzer mit vor der Anschlußstelle gekrümmt ausgebildeter Zuführungsleitung Die Erfindung bezieht sich auf Plattenlufterhitzer, bei denen die Gaszuführungsleitung vor der Anschlußstelle gekrümmt ausgebildet ist. Um den ,einzelnen Gaskanälen gleiche Rauchgasmengen zuzuführen, ist bereits vorgeschlagen worden, in. die Zuführungsleitung besondere, den Gasstrom unterteilende Lenkflächen einzubauen. Die Verteilung der Gasmengen auf die einzeluen sich ergebenden Kanalgruppen bleibt jedoch trotzdem eine ungleichmäßige.Plate air heater with a curved shape in front of the connection point Supply line The invention relates to plate air heaters in which the gas supply line is curved in front of the connection point. To the To supply the same amount of smoke gas to individual gas ducts has already been proposed have been, in. the supply line special, the gas flow dividing steering surfaces to be built in. The distribution of the gas quantities to the individual resulting channel groups however, it remains uneven.

Um diese Schwierigkeit zu beseitigen und gleichzeitig den Einbau von Ablenkflächen überhaupt zu vermeiden, werden gemäß der Erfindung die Lufberhitzerkörper so eingerichtet, daß der freie Querschnitt der Rauchgaskanäle an dem äußeren Umfang der Zuleitung am kleinsten,, an dem inneren Umfang am größten und dazwischen entsprechend abgestuft ist. Für einen gleichmäßigen, Wärmeaustausch können, dann auch die Luftkanäle des Erhitzers einte entsprechende Querschnittsänderung haben.To eliminate this difficulty and at the same time the installation of Avoid deflecting surfaces at all, according to the invention, the air heater bodies set up so that the free cross section of the flue gas channels on the outer circumference smallest of the supply line, largest on the inner circumference and correspondingly in between is graded. The air ducts can also be used for an even heat exchange of the heater have a corresponding change in cross-section.

In der Zeichnung ist die Erfindung an einem auf den gemauertem. Fuchs aufgesetzten Lufterhitzer zur Darstellung gebracht.In the drawing, the invention is based on a bricked. Fox attached air heater brought to the display.

An den waagerecht geführten Fuchs i schließt sich eine nach aufwärts gekrümmte Zuführungsleitunj z am, welche die Rauchgase :dem Lufterhitzer 3,zuführt, der nur durch einen einzelnen Wärmeaustauschkörper veranschaulicht ist. Letzterer besitzt senkrechte Kanäle q. für die Rauchgase und waagerechte Kanäle 5 für die zu erwärmende Luft, welche die ersteren kreuzen. Die Rauchgaskanäle q. sind nun so eingerichtet, daß ihr freier Querschnitt nach der äußeren Krümmungsseite der Zuführungsleitung allmählich abnimmt, also an ihrem äußeren Umfang am kleinsten und an -dem inneren Umfang am größten ist, während er dazwischen entsprechende Abstufungen aufweist. Dadurch wird eine vollkommen gleichmäßige Beaufschlagung der Durchgangskanäle zur Vermeidung störend wirkender Stauungen erzielt.The horizontally guided fox i is followed by an upward curved feed line, which feeds the flue gases: to the air heater 3, which is illustrated only by a single heat exchange body. The latter has vertical channels q. for the flue gases and horizontal channels 5 for the air to be heated crossing the former. The flue gas ducts q. are now set up so that their free cross-section to the outer side of the curvature Feed line gradually decreases, so the smallest on its outer circumference and is greatest on the inner circumference, while there are corresponding gradations in between having. This results in a completely uniform loading of the through channels achieved to avoid disruptive congestion.

Um außerdem eine gleichmäßige Wärmeübertragung auf .die durch die Luftkanäle 5 strömende Frischluft zu erzielen, können auch diese Luftkanäle eine entsprechende Querschnittsänderung haben.In addition, in order to ensure an even heat transfer to .through the To achieve air channels 5 flowing fresh air, these air channels can also be a have a corresponding change in cross-section.
