Description
Zur- Erwärmung öder Vorwärmung von Gasen, z. B. Luft, werden Geräte verwendet, die in der Regel so arbeiten, daß das wärmeabgebende :und das zu erwärmende Medium durch eine Trennwand voneinander getrennt sind. Der Wärmeaustausch erfolgt durch Wärmeleitung durch die Trennwand. Zur Vermeidung von Wärmeverlusten werden die Außenwände dieser Geräte isoliert.For heating or preheating of gases, e.g. B. Air, become devices used, which usually work in such a way that the heat emitting: and that to be heated Medium are separated from each other by a partition. The heat exchange takes place by conduction through the partition. To avoid heat loss, be insulated the outer walls of these devices.
Zum Betrieb eines Gasvorwärmers im Sinne der vorliegenden Erfindung findet das Verfahren zum Betreiben eines mit einer Ausmauerung versehenen Industrieofens, bei dem unter Druck befindliche Luft durch das Mauerwerk des Ofens in entgegengesetzter Richtung des Verlaufes der Wärmeableitung :geblasen wird, Anwendung. Hierbei wird das zu erwärmende Gas durch das Mauerwerk von Kanälen, die heiße Gase führen, hindurchgedrückt.To operate a gas preheater within the meaning of the present invention finds the procedure for operating a brick-lined industrial furnace, at the pressurized air through the masonry of the furnace in opposite Direction of the course of heat dissipation: blown, application. Here is the gas to be heated is pushed through the masonry of ducts that carry hot gases.
Die Abbildung zeigt schematisch einen so @betriebenen Vorwärmer. Die wärmeabgebenden heißen Gase, z. B. Abgase eines Industrieofens, durchstreichen einen oder mehrere Kanäle q @innerhalb des Vorwärmers und geben dort einen Teil ihrer Wärme an das Mauerwerk r ab. Das bei s unter Druck zugeführte und zu erwärmende Gas verteilt sich in dem leeren oder mit porösem Material angefüllten Raum t. Das durch das Mauerwerk r gedrückte Gas wird,inbeliebig angeordneten und geformten Kanälen u aufgefangen und in einem oder mehreren Kanälen v gesammelt, um von dort aus durch den Stutzen w der Verwendungsstelle zugeleitet zu werden. Um den Austritt des zu erwärmenden Gases aus dem Mauerwerk r in den Kanal q zu verhindern, kann eine aus dichtem Material, z. B. Metall, hergestellte Trennwand m eingebaut werden. Durch die Zuführung des kalten und im Gasvorwärmer zu erwärmenden Mediums bei s in den Außenmantel t werden die Wärmeverluste der Außenwand des Gasvorwärmers, so wie sie bei den bekannten, auch mit Isolierung versehenen Wärmeaustauschern unvermeidlich sind, nicht nur vermieden, sondern es wird auch diese Wärmemenge von dem zu erwärmenden Medium aufgenommen und somit nutzbar verwertet.The figure shows a schematic of a preheater operated in this way. the heat-emitting hot gases, e.g. B. Exhaust gases from an industrial furnace, cross out one or several channels q @ within the preheater and give some of their Heat to the masonry r. That which is supplied under pressure and to be heated at s Gas is distributed in the empty space or space t filled with porous material. That gas pushed through the masonry r, in any arranged and shaped ducts u caught and collected in one or more channels v to go through from there the nozzle w to be forwarded to the point of use. To the exit of the too To prevent warming gas from the masonry r into the channel q, one can get out dense material, e.g. B. metal, manufactured partition m can be installed. By the supply of the cold medium to be heated in the gas preheater at s in the Outer jacket t are the heat losses of the outer wall of the gas preheater, just like them unavoidable in the known heat exchangers, which are also provided with insulation are not only avoided, but it is also this amount of heat from the one to be heated Medium absorbed and thus usable recycled.
