Description
Treppenrostfeuerung, insbesondere für Braunkohle, Torf, Lohe, Holzanfall u. dgl., mit Trocknung und Vorvergasung der Brennstoffe im Fülltrichter durch Zuführung vorgewärmter Luft. Die Erfindung bezieht sich auf eine Rostfeuerung, insbesondere für Braunkohle, Torf, Lohe, Holzanfall u. dgl., bei welcher die Brennstoffe, während sie durch den Fülltrichter zum Rost übergehen, durch Zuführung von gewä-mter Verbrennungsluft einer teilweisen Vergasung unterzogen werden.Stair grate firing, especially for brown coal, peat, tan, wood and the like, with drying and pre-gasification of the fuels in the hopper by feeding preheated air. The invention relates to grate firing, in particular for lignite, peat, tan, wood and the like, in which the fuels while they pass through the filling funnel to the grate by supplying heated combustion air be subjected to partial gassing.
Das Wesen der Erfindung besteht darin, daß die Verbrennungsluft durch Röhren hin4urchgeführt wird, welche in der Wand des Fülltrichters sitzen und in einer Kammer liegen, durch welche die Rauchgase hindurchgezogen werden, beispielsweise mit Hilfe eines Saugventilators. Die Rauchgase erhitzen hierbei die Luft sehr stark.The essence of the invention is that the combustion air through Tubes, which sit in the wall of the hopper and in a chamber, through which the smoke gases are drawn, for example with the help of a suction fan. The smoke gases heat the air very strongly.
Auf der Zeichnung ist eine Ausführungsform zur Darstellung gebracht, und zwar zeigt Abb. i eine Rostfeuerung im Schnitt, und Abb_ 2 zeigt eine Ansicht, von rechts gesehen, bei fortgelassenen Reinigungstüren m.In the drawing, an embodiment is shown, namely Fig. i shows a grate furnace in section, and Fig_ 2 shows a view, seen from the right, with omitted cleaning doors m.
Der Brennstoff fließt durch ein oder mehrere Rohre e, die von einem Vortrockner herkommen können; in den Fülltrichter d, welcher in bekannter `reise zur Regelung des Zuflusses einen Schieber besitzen kann, für den die Einstellvorrichtung ch vorgesehen ist. Mit z sind die Wasserröhren des Kessels bezeichnet, h ist der Treppenrost und k der Planrost. An der unteren Wand des Fülltrichters d ist ein selbsttätig wirkender Beschickungssektor i angeordnet, dessen Hub verstellbar sein kann und auf welchen das Zahnradvorgelege ch einwirken kann, für dessen Bewegung Stufenscheiben etwa für drei Geschwindigkeiten vorhanden sein können. Den Treppenrost h kann man in seiner Schrägstellung verstellen, damit er sich verschiedenartigen Brennstoffen anpassen kann.The fuel flows through one or more tubes e, which can come from a pre-dryer; into the hopper d, which in a known way can have a slide for regulating the inflow, for which the adjusting device ch is provided. The water pipes of the boiler are marked with z , h is the step grate and k is the plan grate. On the lower wall of the hopper d there is an automatically acting charging sector i, the stroke of which can be adjustable and which can be acted on by the counter gear ch, for the movement of which step disks can be provided for approximately three speeds. The step grate h can be adjusted in its inclination so that it can adapt to different types of fuel.
Ein oder mehrere Saugzugventilatoren führen e @'crbrennungsluft zu, was in Abb. i rechts durch Pfeile angedeutet ist.One or more induced draft fans supply combustion air, which is indicated by arrows on the right in Fig. i.
Die eine Wand des Fülltrichters d ist von Röhren g durchsetzt, durch welche ein Teil der vorgewärmten Verbrennungsluft zu strömen hat, während der andere Teil zu dem Schrägrost h hingelangt, wie die Pfeile zeigen.One wall of the hopper d is penetrated by tubes g which part of the preheated combustion air has to flow while the other Part to the inclined grate h, as the arrows show.
Die Röhren g sind von einer Kammer f umschlossen, durch welche die Rauchgase hindurchtreten, wie in Abb. 2 durch Pfeile angedeutet ist. Die durch die Röhren g streichende Verbrennungsluft wird hierdurch noch mehr erhitzt, und dies hat zur Folge, daß der in dem Trichter d noch sackende Brennstoff zum Teil vergast wird, bevor er auf den Treppenrost h gelangt, m ist eine dichtumschließende Tür, durch welche die Reinigung des Rostes und des Aschenfalles vorgenommen werden kann.The tubes g are enclosed by a chamber f through which the Flue gases pass through, as indicated by arrows in Fig. 2. The through the Combustion air brushing tubes is thereby heated even more, and this has the consequence that the fuel still sagging in the funnel d is partially gasified before it reaches the step grate h, m is a tightly enclosing door, through which the grate and the ash fall can be cleaned.
