Description

Halbgasfeuerung, bei der die im Füllschacht sich entwickelnden Dämpfe unter das Feuer geleitet werden. Die Erfindung betrifft eine Halbgasfeuerung, bei der die in dem Füllschacht entstehenden Wrasen und Schwielgase unter den Rost geleitet werden, und der Gegenstrand der Erfindung ist eine Einrichtung, durch die die Wrasen auf ihrem Wege zum Teil rLiadergeschlagen werden, um eine Dämpfung des Feuers durch ü'bermäß'ige Wasserzufuhr zu vermeiden.Half gas firing, in which the vapors developing in the filling shaft be passed under the fire. The invention relates to a half-gas furnace which directs the vapors and callous gases generated in the hopper under the grate be, and the opposite of the invention is a device through which the vapors on their way to some rLiader be beaten in order to dampen the fire by Avoid excessive water intake.

In der Zeichnung ist die neue Hallbgasfeuerung in Abb..r im senkrechten Längsschnitt und in Abb. 2 im wagerechten Schnitt nach A-B der Ab'b. i dargestellt.In the drawing, the new Hall gas firing in Fig..r is in the vertical Longitudinal section and in Fig. 2 in the horizontal section according to A-B of Fig. i shown.

Der Brennstoff wird in dem Füllschacht a, wie an sich bekannt, vorgewärmt und vorge-. trocknet. Im Ausführungsbeispiel geschieht dies dadurch, daB ein Teil der heißen Verbrennungsgase durch einen mittels Schiebers b absperrbaren Kanal c in den Füllschacht durchquerende Heizrohre d geleitet wird. Der für diese Führung der erforderliche Zug wird dadurch herbeigeführt, daB die Heizrohre d durch den Kanal n mit dem letzten Zuge .der Feuerung verkehren. Die durch diese Vorwärmung entstehenden Wrasen und Schwelgase werden nun durch die Auslässe g des Füllschachtes a und durch den Kanal na unter den Rost e bzw. in den Heizraum f geleitet, bilden beim Hindurchziehen durch die glühende Brennstoffschicht Wassergas, und die Beimischung des Wassergases zu den aus dem brennenden Heizstoffe entstehenden Gasen bewirkt die Verlegung des eigentlichen Verbrennungsvorganges hinter den Rundbrenner o.As is known per se, the fuel is preheated and preheated in the filling shaft a. dries. In the exemplary embodiment, this takes place in that part of the hot combustion gases is passed through a duct c, which can be shut off by means of a slide b, into the heating pipes d that crosses the filling shaft. The draft required for this guidance is brought about by the fact that the heating pipes d pass through the channel n with the last draft of the furnace. The vapors and carbonization gases resulting from this preheating are now passed through the outlets g of the filling shaft a and through the channel na under the grate e or into the heating room f, form water gas when drawn through the glowing fuel layer, and the admixture of water gas to the Gases arising from the burning fuel cause the actual combustion process to be relocated behind the circular burner or the like.

Um nun zu verrrieiden, daß bei Verwendung sehr feuchten Brennstoffes ein Überschuß von Dämpfen hinderlich auf die Verbrennung wirkt, wird, wie eingangs erwähnt, gemäß vier Erfindung ein Teil der Wrasen oder Dämpfe auf dem Wege zum Roste niedergeschlagen. Dies kann durch Verlegung des Kanals m an eine von der Feuerung nicht oder wenig erwärmte Stelle geschehen. Im Ausführungsbeispiel ist zu diesem Zwecke der Kanal in das Mauerwerk eingebaut. Er kenn aber erforderlichenfalls auch außerhalb desselben vorgesehen werden. Anstatt die Abkühlung der Dämpfe durch Verlegung ihrer Leitung an eine kühlere Stelle der Anlage herbeizuführen, kann sie natürlich auch auf andere Weise erreicht werden, z. L. durch eine besondere regelbare Kühleinrichtung.In order now to verrrieiden that when using very moist fuel an excess of vapors has an adverse effect on the combustion, as at the beginning mentioned, according to four invention, a part of the vapors or vapors on the way to the grate dejected. This can be done by relocating the duct m to one of the furnace not or little heated spot happen. In the exemplary embodiment is about this Purposes of the channel built into the masonry. But if necessary, he also knows be provided outside of the same. Instead of cooling the fumes by laying Of course, it can bring its line to a cooler part of the system can also be achieved in other ways, e.g. L. by a special adjustable cooling device.
