Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es sind Lufterhitzer bekannt, bei welchen die Luft durch von außen beheizte Röhren hindurchgeht, von denen jede einen um die Längsachse schraubenartig verdrehten Streifen enthält, zum Zwecke, die durch die Röhren ziehenden Gase behufs Verstärkung des Wärmeaustausches inniger mit den Rohrwänden in Berührung zu bringen.There are air heaters known in which the air through externally heated tubes goes through, each of which has a strip twisted in a helical manner about the longitudinal axis contains, for the purpose, the gases pulling through the tubes for the purpose of strengthening the heat exchange more intimately with the tube walls to bring in touch.

Das Neue gemäß der Erfindung, wodurch dieser Wärmeaustausch noch verstärkt wird, besteht darin, daß an den Schraubenstreifen schräge Leitplatten, Flügel, Vorsprünge o. dgl. derart versetzt zueinander angebracht sind, daß sie die Luft gegen die Innenwandung des Rohres lenken. Hierdurch wird eine innigere Berührung der Luft mit der Heizfläche der Röhren erzielt. Die Leitplatten können von beliebiger Form und in einem beliebigen Winkel angebracht sein.The novelty according to the invention, whereby this heat exchange is further enhanced, consists in that inclined guide plates, wings, projections o. The like on the screw strips. are mounted offset to each other that they push the air against the inner wall steer the pipe. This creates a closer contact between the air and the heating surface of the tubes achieved. The guide plates can be of any shape and in one be attached at any angle.

Auf der Zeichnung ist die Erfindung beispielsweise veranschaulicht, und zwar ist:The invention is illustrated by way of example in the drawing, namely:

Fig. ι ein Längsschnitt eines Luftrohres 1 eines Lufterhitzers.Fig. Ι a longitudinal section of an air tube 1 an air heater.

Eine Reihe solcher Rohre bilden in bekannter Weise den Erhitzer und werden durch eine obere und eine untere Kammer 2,3 verbunden; diese Vorrichtung wird vorteilhaft in dem Rauchkanal oder dem Schornstein untergebracht.A number of such tubes form the heater in a known manner and are connected by an upper and a lower chamber 2,3; this device becomes advantageous housed in the smoke duct or chimney.

Fig. 2 ist ein Schnitt nach Linie a-b der Fig. I.Fig. 2 is a section along the line from Fig. I.

Fig. 3 ist eine Ansicht des Erhitzers.Fig. 3 is a view of the heater.

Der Schraubenstreifen 4 wird mittels eines daran befestigten T-Stückes 5 innerhalb eines jeden Rohres 1 des Erhitzers angebracht; an dem Streifen 4 werden Flügel 6 befestigt, welche so geformt, gestellt oder gebogen sind,- daß sie die Luft, die schraubenartig durch das Rohr fließt, aufspalten und sie gegen die Innenfläche des Rohres ablenken.The screw strip 4 is by means of an attached T-piece 5 within a attached to each tube 1 of the heater; wings 6 are attached to the strip 4, which are so shaped, placed or bent, - that they convey the air, which is helical flows through the pipe, splitting and deflecting it against the inner surface of the pipe.
