Description
Feuerung mit Einrichtung zum Ausbrennen von Asche, Schlacke und Rostdurchfall Beim Abschlacken feststehender Roste fallen unverbrannte Teile des Brennstoffes durch die Luftspalten in den Schlackenbunker und werden ungenutzt abgefahren. Um die fühlbare Wärme der abgezogenen Asche und Schlacke auszunutzen, hat man bereits vorgeschlagen, die Feuerung mit einem Nachverbrennungsrost zu versehen, so daß die Verbrennungsluft durch die glühenden Rückstände vorgewärmt zum Hauptrost strömt.Firing with device for burning out ash, slag and rust diarrhea When slagging fixed grates, unburned parts of the fuel fall through the air gaps into the slag bunker and are driven off unused. Around You already have to use the sensible warmth of the withdrawn ash and slag proposed to provide the furnace with an afterburning grate, so that the Combustion air, preheated by the glowing residues, flows to the main grate.
Gegenüber diesen bekannten Feuerungen besteht das Wesen der Erfindung darin, daß unterhalb des Rostes eine über die ganze Bunkeröffnung reichende Platte vorgesehen ist, die vorteilhaft nach dem Heizerstand zu geneigt und ariidieser Stelle mit Öffnungen für die Abführung der Rückstände und den Durchtritt von Luft versehen ist.The essence of the invention is in relation to these known firings in that below the grate a plate extending over the entire bunker opening is provided, which is advantageously inclined to the stoker and ariidieser point provided with openings for the discharge of residues and the passage of air is.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung an einem Muldenrost im Schnitt veranschaulicht.In the drawing, an embodiment of the invention is on one Trough grate illustrated in section.
Unterhalb des Rostes ist in einigem Abstand von diesem über die ganze Länge des Bunkers eine vorteilhaft aus feuerfestem Baustoff, z. B. Schamotte, hergestellte Platte a vorgesehen, die entweder auf Eisenträgern ruht oder auch, durch ein Gewölbe versteift, in sich freitragend ist. Die Schamotteplatte a ist nach dem Heizerstand zu geneigt, um das Herunterziehen des durchgefallenen Brennstoffes zu erleichtern. An der tiefsten Stelle der Platte a befindet sich eine Öffnung b, die dazu dient, einerseits den auf die Platte a durchgefallenen Brennstoff nach unten in den Bunker zu befördern und anderseits durch sie Luft einzulassen, die zum Ausbrennen des heruntergefallenen Brennstoffes und der Schlacke dient. Durch die Öffnung b wird ferner erreicht, daß die in den Bunker herunterfallende Asche sich in einem Winkel anböscht. Diesem Winkel entsprechend ist an der gegenüberliegenden Wand des Bunkers eine Öffnung c vorgesehen, durch die Frischluft eintritt. Die Frischluft streicht über die angesammelte Asche, nimmt die noch fühlbare Wärme der Asche auf und kühlt dabei gleichzeitig die Unterseite der Platte a. Die so vorgewärmte Frischluft tritt dann durch die Öffnung b, bestreicht und verbrennt den Durchfall auf 'der Platte a und tritt dann kräftig vorgewärmt zum Rost.Below the grate is at some distance from this over the whole Length of the bunker advantageously made of refractory material, e.g. B. chamotte produced Plate a provided, which either rests on iron girders or through a vault stiffened, self-supporting. The fireclay panel a is after the stoker's stand too sloped to make it easier to pull down the fallen fuel. At the lowest point of the plate a there is an opening b, which is used to on the one hand, the fuel that has fallen onto plate a down into the bunker to convey and, on the other hand, to let air through them to burn out the fallen Fuel and slag is used. Through the opening b it is also achieved that the ashes falling into the bunker slope up in an angle. That angle accordingly an opening c is provided on the opposite wall of the bunker, enters through the fresh air. The fresh air brushes over the accumulated ashes, absorbs the still noticeable warmth of the ash and at the same time cools the underside the plate a. The fresh air preheated in this way then passes through the opening b and burns the diarrhea on 'the plate a and then occurs vigorously preheated to the grate.
