Description

Schwelofen Man hat bereits Brennstoffe in der Weise geschweli, daß man heiße Gase und Dämpfe mit einer zur Schwellung geeigneten Temperatur in derartigen Mengen durch die zu schw elenden Schichten hindurchgeblasen hat, daß diese auf ihrer Unterlage in lebhafte, wallende Bewegung geraten.Smoldering furnace One has already smoldered fuels in such a way that one hot gases and vapors with a temperature suitable for swelling in such Amounts blown through the layers to be smoldering that these on their Lively, undulating motion on the surface of the surface.

Es hat sich nun gezeigt, daß dieses Verfahren besonders vorteilhaft ausgeführt werden kann, wenn man den zu schweienden Brennstoff innerhalb des Ofens in mehreren übereinander auf Rosten liegenden Schichten innerhalb des Ofens anordnet, und zwar derart, daß er in dem in entgegengesetzter Richtung zu ihm geführten Gas- bzw. Dampfstrom die einzelnen Schichten der Reihe nach durchwandern muß. Dabei gehen die den Ofen durchziehenden inerten Gase oder Dämpfe so der Reihe nach durch die einzelnen Schichten hindurch, daß jede einzelne Schicht in wallende Bewegung gesetzt wird. It has now been shown that this method is particularly advantageous can be performed when the fuel to be welded is inside the furnace arranged in several layers on top of each other on grids inside the furnace, in such a way that he is in the opposite direction to him led gas or steam flow must pass through the individual layers in sequence. Go there the inert gases or vapors passing through the furnace so in sequence through the through individual layers so that each individual layer is set in flowing motion will.

An Hand der Zeichnung sei eine Ausführungsform des Schwelofens näher zur läutert. An embodiment of the smoldering furnace is closer to the drawing to purify.

Der Schwelofen a enthält die übereinanderliegenden Roste b, c, d und e. Der zu schwelende Brennstoff gelangt durch die Schnecke k auf den obersten Rost b. Vermittels der Schleusen ü geht der Brennstoff von einem Rost zum andern und wird schließlich durch den Auslaufm und die Schnecke in ausgeschweltem Zustande ausgetragen. Ein Brennerf dient zur Herstellung der inerten Gase, die nach Durchziehen der einzelnen mit Brennstoff beladenen Etagen bei g unter Mitführung der Schweldämpfe abziehen. Zweckmäßig läßt man über jeder Brennstoffschicht einen gewissen Gasraum frei, damit nicht zuviel Staub mitgerissen wird. The smoldering furnace a contains the grids b, c, d, one on top of the other and e. The fuel to be smoldered reaches the top through the screw k Grate b. By means of the locks ü the fuel goes from one grate to the other and is finally in an exhausted state through the outlet and the snail carried out. A burner is used to produce the inert gases that are drawn through of the individual floors loaded with fuel at g with entrainment of the smoldering vapors pull off. It is expedient to leave a certain gas space above each fuel layer free so that too much dust is not carried away.

Es ist ferner zweckmäßig, die Rostflächen möglichst langgestreckt auszubilden, so daß der Brennstoff beim Durchwandern einen großen Weg zurückzulegen hat. Dadurch wird ein besserer Wärmeausgleich zwischen den durchgehenden Gasen und dem Brennstoff erreicht. It is also useful for the grate surfaces to be as elongated as possible train so that the fuel to travel a long way when wandering through Has. This results in a better heat balance between the gases passing through and reached the fuel.

In der Zeichnung ist die Regulierung der Brennstoffhöhe auf den einzelnen Rosten mit Drehschieberschleusen gezeichnet. Eblensogut kann jedoch die Abführung des Brennstoffs auch mit anderen Mitteln, z. B. mit Schiebern, oder automatisch ausgeführt werden. Wesentlich ist, daß der von oben nach unten gehende Brennstoffstrom den aufsteigenden inerten Gasen über die einzelnen Etagen so entgZegengeführt wird, daß das Brennstoffbett sich in jeder einzelnen Etage in auf- und abwallender Bewegung -befindet. In the drawing is the regulation of the fuel level on each Grates drawn with rotary valve sluices. However, discharge can also be good the fuel also by other means, e.g. B. with sliders, or automatically are executed. It is essential that the fuel flow going from top to bottom the rising inert gases over the individual floors is thus countered that the fuel bed moves up and down on every single floor - located.

Mit dem Ofen wird eine wesentlich höhere Leistung als in den bisher bekannten Systeten erreicht. bei schonendster Behandlung der Schweldämpfe und bester Ausnutzung der zugeführten Wärme. With the furnace there will be a much higher output than in the past known systems. with the most gentle treatment of the smoldering vapors and the best Utilization of the supplied heat.

PATENTANSPRUCH: Schwelofen zur Ausführung eines Schwelverfahrens, bei dem heiße inerte oder schwach sauerstoffhaltige Gase oder Dämpfe mit einer zur Schwellung geeigneten Temperatur in derartiger Menge durch die zu schwelende Brennstoffschicht hindurchgeblasen werden, daß diese auf ihrer Unterlage in lebhafte Bewegung gerät, dadurch gekennzeichnet, daß innerhalb des Ofens mehrere Brennstoffschichten übereinander auf Rosten derart angeordnet sind, daß der Brennstoff in dem in entgegen gesetzter Richtung zu ihm geführten Gas-bzw. Dampfstrom die einzelnen Brennstoffschichten der Reihe nach durchwandern muß und daß in jeder dieser Brennstoffschichten eine lebhafte Bewiegung dieser Brennstoffscbicht auf ihrer Unterlage stattfindet. PATENT CLAIM: Smoldering furnace for carrying out a smoldering process, in which hot inert or weakly oxygenated gases or vapors with a for Swelling suitable temperature in such an amount by the fuel layer to be smoldered be blown through so that it starts moving vigorously on its base, characterized in that several fuel layers on top of one another within the furnace are arranged on grates so that the fuel in the opposite Direction to him led gas or. Steam flow through the individual fuel layers must walk through in sequence and that in each of these fuel layers one vigorous agitation of this fuel layer takes place on its base.
