Description

Vorrichtung zur Erwärmung von strömenden Gasen auf elektrischem Wege Die Erfindung betrifft eine Vorrichtung zur Erwärmung von strömenden Gasen auf elektrischem Wege, bei welcher ein von den Gasen durchströmtes Rohrstück innerhalb eines feuerfesten, von einem Gehäuse umgebenen Heizwiderstandsträgers angeordnet ist.Device for heating flowing gases by electrical means The invention relates to a device for heating flowing gases to electrical Paths in which a pipe section through which the gases flow inside a refractory, is arranged surrounded by a housing heating resistor carrier.

Es sind Vorrichtungen zur Erwärmung von strömenden Gasen bekannt, bei welchen der elektrische Widerstand auf dem Rohrstück unlösbar befestigt und das Rohrstück in einem Gehäuse angeordnet ist. Bei diesen bekannten Einrichtungen fehlt die Möglichkeit, das Rohrstück auszuwechseln, ohne die ganze Vorrichtung auseinanderzunehmen. Aus diesem Grunde können sie nur bei einem konstanten, vorher bestimmten Gasdruck Anwendung finden.Devices for heating flowing gases are known, in which the electrical resistance is inextricably attached to the pipe section and the pipe section is arranged in a housing. In these known facilities there is no possibility of replacing the pipe section without disassembling the entire device. For this reason, they can only work at a constant, previously determined gas pressure Find application.

Um die Möglichkeit zu schaffen, durch einfache Auswechslung des von dem Gas durchströmten Rohrstückes die Vorrichtung verschiedenen Gasdrucken anzupassen, indem jeweils ein dem betreffenden Gasdruck entsprechender Rohrquerschnitt gewählt wird, ist bei der Vorrichtung gemäß der Erfindung das Rohrstück in dem Heizwiderstandsträger mit Spiel eingeschoben und an dem Gehäusie durch leicht lösbare Mittel, z. B. Schraubenringe, befestigt.In order to create the possibility of simply changing the adapt the device to different gas pressures according to the pipe section through which the gas flows, by selecting a pipe cross-section corresponding to the gas pressure in question is, in the device according to the invention, the pipe section in the heating resistor support inserted with play and attached to the housing by easily releasable means such. B. screw rings, attached.

Die Zeichnung zeigt als Ausführungsbeispiel der Erfindung einen Schnitt durch eine Gasheizvorrichtung.The drawing shows a section as an embodiment of the invention by a gas heater.

Ein Rohr 2, durch das die zu erwärmenden Gase strömen, ist an seinen beiden Enden mit Außengewinde versehen. An dem oberenEnde ist eine Anschlußmuffe 2a mit Außengewinde, an dem unteren Ende eine Anschlußmuffe 2b mit Innengewinde aufgeschraubt, die zum Einbau des Rohres 2 in eine Gasleitung dienen. Das Rohr ist von einer Hülse 4 aus feuerfestem Stoff umgeben, auf die ein Widerstandsdraht 3a aus Neusilber aufgewikkelt ist. Eine Umhüllung 4 umschließt die Hülse und den Widerstandsdraht. Auf ihr sind Stromanschlußklemmen 5 und 5a befestigt, die mit den Enden des Widerstandsdrahtes 3a verbunden sind. Die Umhüllung 4 besteht aus einem zylindrischen Mantel, der an den Stirnenden durch Deckel verschlossen ist. Sie ist mittels zweier auf den Rohrenden verschraubter Ringe 6 und 6a an dem Rohrbefestigt.A pipe 2 through which the gases to be heated flow is on his provided with external thread on both ends. At the upper end is a connecting sleeve 2a with external thread, at the lower end a connecting sleeve 2b with internal thread unscrewed, which are used to install the pipe 2 in a gas line. The pipe is surrounded by a sleeve 4 made of refractory material on which a resistance wire 3a is wound from nickel silver. A sheath 4 encloses the sleeve and the resistance wire. Power connection terminals 5 and 5a are attached to it, which are connected to the ends of the resistance wire 3a are connected. The envelope 4 consists of a cylindrical jacket that is attached to the front ends is closed by a lid. It is by means of two on the pipe ends screwed rings 6 and 6a attached to the pipe.

Wenn das Rohr 2 ersetzt oder bei sehr unterschiedlichen Drücken in der Gasleitung ausgewechselt werden soll, wird eine der Anschlußmuffen 2a oder 2b und einer der zugehörigen Ringe 6a oder 6b abgeschraubt. Das Rohr kann dann aus der Vorrichtung herausgezogen und durch ein anderes ersetzt werden.When the tube 2 is replaced or at very different pressures in the gas line is to be replaced, one of the connecting sleeves 2a or 2b and unscrewed one of the associated rings 6a or 6b. The pipe can then be taken out pulled out of the device and replaced by another.

Die Hülse 3 und die Umhüllung 4 begrenzen eine isolierende Luftschicht, durch die Wärmeverluste vermieden werden; der Zwischenraum kann aber auch mit irgendeinem geeigneten Isolierstoff ausgefüllt sein.The sleeve 3 and the casing 4 delimit an insulating layer of air, through which heat losses are avoided; but the gap can also be with any suitable insulating material.
