Description

Die Erfindung betrifft einen feuerbeheizten Lufterhitzer, bei welchem die zu erwärmende Luft, Gase, oder Dämpfe durch waagerecht liegende Rohre strömt.
Bei der Ausführung der Rohre in Gußeisen treten leicht Spannungen auf, die zum Reißen der Rohre führen können. Dieser Nachteil soll erfindungsgemäß beseitigt werden. Die Rohre erhalten in bekannter WeiseThe invention relates to a fire-heated air heater in which the air, gases or vapors to be heated flows through horizontally lying pipes.
When the pipes are made of cast iron, tensions easily occur which can lead to the pipes tearing. This disadvantage is to be eliminated according to the invention. The tubes received in a known manner

to tropfenförmigen Querschnitt und am Tropfenkopf, der von den Feuergasen beaufschlagt wird, Einbuchtungen in Längsrichtung der Rohre. Abgesehen davon, daß durch die Einbuchtungen die wärmeaufnehmende Fläche vergrößert wird, gestatten diese im Verein mit den verhältnismäßig längen, sich im spitzen Winkel treffenden Schenkeln eine gewisse Federung, durch welche ein Ausgleich der auftretenden Spannungen eintritt.to teardrop-shaped cross-section and at the drop head, which is acted upon by the fire gases becomes, indentations in the longitudinal direction of the pipes. Apart from the fact that through the indentations the heat-absorbing surface is enlarged, allow this in conjunction with the relatively long, in the Acute angles meeting the legs a certain suspension, through which a compensation the occurring tension occurs.

In der Abbildung ist ein solches Rohr im Querschnitt dargestellt.Such a pipe is shown in cross section in the figure.
