Description

Lufterhitzer. Bei Lufterhitzern, die aus einem System von Rohren gebildet sind, durch welche die kalte zu erwärmende Luft streicht, während senkrecht zu diesen Rohren die Heizgase durch die zwischen den Rohren vorhandenen Zwischenräume strömen, tritt der Übelstand auf, daß die unteren, von den Heizgasen zuerst getroffenen Rohre heißer als die obe_ en Rohre werden, also schneller als letztere zerstört werden.Air heater. In the case of air heaters, which are formed from a system of pipes are through which the cold air to be heated passes, while perpendicular to these Pipes the hot gases flow through the spaces between the pipes, the inconvenience occurs that the lower pipes hit by the heating gases first get hotter than the upper pipes, so they are destroyed faster than the latter.

In der Zeichnung ist eine neue Bauart dargestellt, durch welche die ungleichmäßige Zerstörung der Rohre vermieden werden soll. B stellt den Fuchs dar, von welchem aus die Heizgase in den Lufterhitzer in der Richtung des Pfeiles a strömen. Sie durchstreichen die zwischen den Rohren A befindlichen Zwischenräume und gelangen unter Vermittelung der Umführungskanäle H und J in den Schornstein S. Die kalte Luft wird an der Seite C eingesaugt, durchstreicht die Rohre A und tritt erhitzt bei D wieder aus.In the drawing, a new design is shown, by which the uneven destruction of the pipes is to be avoided. B represents the fox from which the heating gases flow into the air heater in the direction of arrow a. They pass through the spaces between the pipes A and reach the chimney S through the bypass ducts H and J. The cold air is sucked in on the C side, passes through the pipes A and exits again at D when heated.

Die Neuerung besteht darin, daß die unteren, von den Heizgasen zuerst getroffenen Rohre, z. B. A1 und A2, wesentlich kürzer als die nächstfolgenden Rohre A gewählt werden, und zwar zweckmäßig nur in der Breite des Fuchses. Hierdurch sind, da die Luft von E her an die unteren Rohre A1 und A2 herantritt, diese Rohre stärker gekühlt als die über ihnen liegenden Teile der folgenden Rohre A. Die Kürze der Rohre Al und A2 bewirkt auch, daß der Luftstrom in ihnen schneller fließt als in den oberen Rohren und somit ebenfalls zur Kühlung beiträgt.The innovation is that the lower, of the heating gases first hit pipes, e.g. B. A1 and A2, much shorter than the next tubes A can be chosen, and expediently only in the width of the fox. As a result, since the air approaches the lower tubes A1 and A2 from E, these tubes are stronger chilled than the parts of the following pipes above them A. The brevity of the Tubes Al and A2 also causes the airflow to flow faster in them than in the upper tubes and thus also contributes to the cooling.
