Description

Feuerung mit durch Feuergase beheiztem Zusatzlufterhitzer. Die Erfindung betrifft eine Feuerung, bei welcher nach der Beschickung des Rostes mit frischen Brennstoffen über diese Brennstoffe Zusatzluft geblasen wird, die auf etwa iooo° C erhitzt ist.Firing with an additional air heater heated by fire gases. The invention relates to a furnace in which after the grate has been charged with fresh Fuels over these fuels additional air is blown to about iooo ° C is heated.

Auf der Zeichnung ist beispielsweise eine Feuerung gemäß der Erfindung im Längsschnitt dargestellt.The drawing shows, for example, a furnace according to the invention shown in longitudinal section.

Die hocherhitzte Zusatzluft wird dadurch dauernd erzielt, daß hinter der Feuerbrücke ein Abstand davon ein gemauerter Schlangenweg k für die Rostgase angelegt ist, durch welchen dünnwandige Rohre lt gelegt sind, die teils in der Vorderwand der Feuerbrücke, teils in den Seitenwänden und der Decke des Feuerraums ausmünden.The highly heated additional air is achieved continuously that behind the fire bridge a distance from it a brick snake path k for the rust gases is created, through which thin-walled pipes are laid, some in the front wall the fire bridge, partly open into the side walls and the ceiling of the firebox.

Die Zusatzluft tritt bei L in den unter der Feuerung breit angelegten Kanal b ein, ge- langt von hier in den Verteilerraum c, strömt durch die Röhren h und bläst aus den Düsen f in den Feuerraum. Die abziehenden, einen Schlangenweg beschreibenden Abgase setzen den größten Teil ihrer Wärme an die Röhren h ab, wodurch die Zusatzluft in den Röhren vorgewärmt und im überhitzerraum x hinter der Feuerbrücke auf die erforderliche hohe Temperatur gelangt, um insbesondere die schwerentzündlichen schweren Kohlenwasserstoffgase restlos verbrennen zu können.The additional air enters at L in the large-scale of the firing channel b, a, Ge arrived from here into the distributor space c, flows through the tubes h and blows from the nozzles f in the combustion chamber. The exhaust gases, which describe a snake path, transfer most of their heat to the tubes h, whereby the additional air is preheated in the tubes and in the superheater space x behind the fire bridge reaches the required high temperature in order to be able to burn the heavy, difficult hydrocarbon gases, in particular, completely .

Durch die Schauluke g kann die Flammenfärbung beobachtet und . hiernach die nötige Zusatzluft eingeregelt werden, um alle Destillationsprodukte aus den Brennstoffen mit hellgelber Flamme zu verbrennen. Die über der Feuerbrücke gekennzeichnete öffnung p zeigt die Stelle an, wo sich die größte Heiztemperatur entwickelt.The color of the flame can be observed through the hatch g. afterwards the necessary additional air can be regulated to remove all distillation products from the Burn fuels with a light yellow flame. The one marked over the fire bridge opening p indicates the point where the greatest heating temperature develops.
