Description

Kohlenstaubfeuerung für Regenerativflammöfen (Inartinöfen, lnischer o. dgl.). Die Erfindung bezieht sich auf eine Kohlenstaubfeuerung für Regenerativöfen (Martinöfen, Mischer o. dgl.).Coal dust firing for regenerative flame furnaces (Inartin furnaces, lnischer or the like). The invention relates to a pulverized coal furnace for regenerative furnaces (Martin ovens, mixers, etc.).

Das Neue besteht darin, daß dem in ungebrochenem Richtungsverlauf auf das Bad gerichteten Luftzug in feiner Strahlenzerlegung der Kohlenstaub zugeführt wird.The novelty consists in the fact that the unbroken course of direction The coal dust is fed into the bath in a fine beam splitting of air directed towards the bath will.

Hierdurch wird neben der raschen Vermischung des Kohlenstaubes gleichzeitig die Vergasung und die Verbrennung der Gasmoleküle erreicht, s o daß eine kurze Flamme entsteht, die, da sie sich in dem auf das Bad gerichteten Luftzug entwickelt, überaus sicher auf das Bad geführt wird.As a result, in addition to the rapid mixing of the coal dust, at the same time the gasification and the combustion of the gas molecules achieved so that a short flame which, as it develops in the draft of air directed towards the bathroom, is extremely high is safely led to the bathroom.

Zweckmäßig trifft man die Ausbildung derart, daß der Luftzug eine vor dem Herdraum nach unten gerichtete. zur Schlackenabsonderung dienende Erweiterung aufweist.Appropriately, one meets the training so that the draft of a downward facing in front of the hearth. Extension serving for slag separation having.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Abb. i zeigt den Ofenkopf im Längsschnitt; Abb. z gibt hierzu einen Schnitt nach der Linie a-b der Abb. i wieder. In den auf das Bad gerichteten Luftzug wird durch die mit il bis % bezeichneten, unten, oben -und seitlich angeordneten Düsen in feiner Strahlenzerlegung der Kohlenstaub eingeführt, wobei die sich bildende.Schlacke in die angedeutete Erweiterung fällt und aus dieser seitlich (vgl. Abb. a) abgezogen wird.An exemplary embodiment of the invention is shown schematically in the drawing shown. Fig. I shows the furnace head in longitudinal section; Fig. Z gives one of this Section along line a-b in Fig. I again. In the breeze directed towards the bathroom is indicated by the symbols below, above and to the side, labeled il to% Nozzles introduced into fine beam splitting of the coal dust, whereby the forming slag falls into the indicated enlargement and withdrawn from it laterally (see Fig. a) will.
