Description

Senkrechter unterbrochen betriebener Kammerofen zum Schwelen von Brennstoffen Gegenstand -des Patents 669 449 ist ein Verfahren zum Schwelen von Brennstoffen in senk'rec'hten, unterbrochen betriebenen Kammeröfen aus feuerfestem Werkstoff mit metallenen Einsätzen. Dabei erstrecken sich die metallenen, I- öder U-förmig ausgebildeten Einsätze mit ihren Grugdplatten über die ganze Fläche der Kammerwände und nehmen d:-hei die Wärme der Kammerwände an, deren Heizzüge mit der Hochtemperaturverkokung entsprechenden Temperaturen - von über i ooo° C betrieben werden.Vertical interrupted operated chamber furnace for smoldering fuels The subject of patent 669 449 is a process for smoldering fuels in vertical, interrupted operated chamber furnaces made of refractory material with metal inserts. Here, the metal, I- barren U-shaped inserts with their Grugdplatten over the entire surface of the chamber walls and be d extend: -hei to the heat of the chamber walls, the heating flues with the high-temperature carbonization corresponding temperatures - operated by over i ooo ° C will.

Die Schwelung des Brennstoffs ist von der in der Zeiteinheit von den Kammerwänden 'über die Eisleneinsätze auf das Schwelgut übergehenden Wärmemenge abhängig. Dias Wärmegefälle von einer Kammerwand zur anderen ist wegen der hohen Wärmeleitfähigkeit des Metalleinsatzes gering und erstreckt sich hauptsächlich von _Grundplatte zu Grundplatte durch die Kohle in der Längsrichtung der Ofenkammer. Die Schwelung des Brennstoffs durch die Wärmeaufnahme aus den Einsätzen ist daher von einer günstigen Ausbildung dieses Wärmegefälles abhängig. Nach dem Hauptpatent ist hierzu ein Kammerofen besonders geeignet, bei dem die Breite der Brennstoffschichten bzw. die Abstände der Einsätze nur :einen Bruchteil der Kammerbreite, beispielsweise 7o mm bei 450 mm Kammerbreite, beträgt. Die Geschwindigkeit des Wärmeübergangs ist :auch von der Stärke der metallenen Einsätze abhängig. Insbesondere mu& die Stärke der Stege so bemessen sein, daß ihr Querschnitt die zur schnellen und gleichmäßigen Erhitzung des- Schwelgutes erforderliche Wärmemenge fortleiten kann, ohne daß sich innerhalb des Steges zwischen Kammerwand. und Kammermitte ein großes Temperaturgefälle einstellt.The smoldering of the fuel differs from that in the unit of time from the Chamber walls' the amount of heat transferred to the Schwelgut via the Eislen inserts addicted. The heat gradient from one chamber wall to the other is because of the high Thermal conductivity of the metal insert is low and extends mainly from _Base plate to base plate through the coal in the longitudinal direction of the furnace chamber. The smoldering of the fuel through the heat absorption from the inserts is therefore depends on a favorable development of this heat gradient. According to the main patent a chamber furnace is particularly suitable for this, in which the width of the fuel layers or the distances between the inserts only: a fraction of the chamber width, for example 70 mm with a chamber width of 450 mm. The speed of heat transfer is : also depends on the strength of the metal inserts. In particular, the Thickness of the webs should be dimensioned so that their cross-section is suitable for rapid and uniform Heating the Schwelgutes can pass the required amount of heat without within the web between the chamber wall. and a large temperature gradient in the middle of the chamber adjusts.

Es hat sich gezeigt, daß diese erforderliche Stärke der als Grundplatten dienenden Stege von der Dicke der Kohleschicht abhängig ist. Nach der Erfindung wird insbesondere ein sehr gleichmäßiger Schwelkoks in kurzer Garung5zeit :erhalten, wenn #die Dicke der quer durch die Ofenkammer verlaufenden .metallenen Stege wenigstens ein Viertel des Abstandes zweier Stege beträgt.It has been shown that this required strength of the base plates serving webs is dependent on the thickness of the carbon layer. According to the invention In particular, a very uniform low-temperature coke is obtained in a short cooking time: if # the thickness of the metal webs running transversely through the furnace chamber is at least a quarter of the distance between two webs.
