Description

t~euerungsanlage mit Treppen-, Schräg- oder mechanischem Rost sowie Vortrocknung und Schwelung des frischen Brennstoffes. Es ist bekannt, daß unter den heutigen Verhältnissen auch minderwertige Brennstoffe in industriellen Anlagen verfeuert werden. müssen. Gemäß .der Erfindung soll eine Einrichtung geschaffen werden, durch welche die aus der Verwendung derartiger Brennstoffe sich ergebenden Schwierigkeiten beseitigt oder gemildert werden sollen. Zu diesem Zweck sollen nasse Brennstoffe, wie Rohbraunkohle, Torf usw., in der Feuerungsanlage selbst vorgetrocknet werden, wozu die strahlende Wärme des. Mauerwerks .der Feuerung benutzt werden soll. Eine Entgasung des Brennstoffs soll hierbei nicht bewirkt werden, vielmehr soll der Brennstoff, wenn er auf den Rost gelangt, noch möglichst gasreich sein. Die Vortrocknung muß deshalb bei einer Temperatur von etwa: 8o bis ioo° erfolgen. Unter diesen Umständen wird der Brennstoff in der Weise veredelt, daß er, bevor er auf den Rost gelangt, von den lästigen Wasserdämpfen. befreit wird. Hierdurch wird der Verlust einer großen toten Rostfläche am oberen Ende des Rostes vermieden, und außerdem der Nachteil, daß die Wasserdämpfe am Kesselschieber mit einer Temperatur von 4000 entweichen, was bei sehr feuchten Brennstoffen einen erheblichen Wärmeverlust bedeutet.control system with stair, inclined or mechanical grate as well as Pre-drying and smoldering of the fresh fuel. It is known that under Today's conditions also include inferior fuels in industrial plants to be burned. have to. According to the invention, a device is to be created through which the resulting from the use of such fuels Difficulties are to be eliminated or alleviated. For this purpose, you want to wet it Fuels such as raw lignite, peat, etc., are pre-dried in the furnace itself for what the radiant heat of the. Masonry. The furnace is to be used. A degassing of the fuel should not be effected here, rather it should the fuel, when it reaches the grate, should still be as rich in gas as possible. the Pre-drying must therefore take place at a temperature of about: 80 to 100 °. Under Under these circumstances, the fuel is refined in such a way that it can be used before it is used the rust gets from the annoying steam. is released. This will make the Avoid losing a large dead grate area at the top of the grate, and moreover the disadvantage that the water vapors at the boiler slide with a temperature of 4000 escape, which means a considerable loss of heat in the case of very moist fuels.

Um diese Zwecke zu erreichen, weist der Erfindungsgegenstand eine Feuerungsanlage mit Treppen-, Schräg oder Vorschubrost auf, bei welchem zur Vortrocknung und Schwelung .des frischen Brennstoffs auf den Fülltrichter ein der Kesselwand anliegender und durch. die strahlende Wärme des Raumes beheizter Schwel- und Trockenschacht aufgesetzt ist.To achieve these purposes, the subject invention has a Firing system with stair, inclined or moving grate, with which for pre-drying and smoldering of the fresh fuel on the hopper in the boiler wall close-fitting and through. the radiant warmth of the room heated smoldering and drying shaft is put on.

Bei einer bevorzugten Ausführungsform kann der Schwelschacht aus einer Reihe wabenartig nebeneinandergereihter senkrechter Retorten bestehen, die zwischen sich. nach dem Heizraum offene Zwischenräume belasser..In a preferred embodiment, the smoldering shaft can consist of a Series of vertical retorts lined up in a honeycomb-like manner, which between themselves. Leave open spaces after the boiler room.

n. Ein. Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung im Schnitt von der Seite dargestellt, es zeigen Abb. i die Anordnung im Schnitt von der Seite, Abb. a und 3 Schnitte nach II-II und III-III in Abb. i.no. Embodiment of the subject matter of the invention is in Drawing shown in section from the side, Fig. I show the arrangement in Section from the side, Fig. A and 3 sections according to II-II and III-III in Fig. I.

Bei dem gezeigten Ausführungsbeispiel ist ein Steilrohrkessel m gezeigt, der in bekannter Weise in einer Einmauerung b untergebracht ist. Unter der Kesselanordnung a kann beispielsweise ein Treppenrost c angeordnet sein, der von einem Gewölbe b überdeckt sein kann. Am vorderen Ende ist in an sich bekannter Weise ein Füllschacht e angeordnet, -durch den der Brennstoff dem Rost zugeführt wird. Zwischen dem Fülltrichter c und .dem Gewölbe d ist eine Zugöffnung f angeordnet, durch welche die Verbrennungsgase ziehen und in üblicher Weise an der Vorderwandung der Kesseleitimauerung vorbeistreichen. Sie werden zwischen den Röhren des Kessels cc hindurchgeführt, wobei vorteilhafterweise eine Zwischenwand h .eingebaut sein kann, um die Rauchgase zu zwingen, an der Wanda g entlang zu streichen. Nach der Erfindung soll die vordere Außenwand c der Kesseleinmauerung möglichst dünn ausgeführt werden. Der Fülltrichter ist hierbei unmittelbar an den Fu3 dieser Wand angeschlossen. In diesen Fülltrichter münden senkrechte Retorten k von beliebiger Anzahl, welche mit der Wand g so zusammengebaut sind, daß sie wabenartig nebeneinandergereiht zwischen sich nach dem Heizraum offene Zwischenräume belassen. Am oberen Ende besitzen die Retorten eine gasdichte Einwurfsvorrichtung l beliebiger Art. An der Vorderwand jeder Retorte können Abzugsstutzen m in verschiedener Höhe zur fraktionierten Ablassung der aufsteigenden Gase angeordnet sein..In the embodiment shown, a steep tube boiler m is shown, which is housed in a walling b in a known manner. Under the boiler assembly a can be arranged, for example, a step grating c, which is supported by a vault b can be covered. At the front end there is a filling chute in a manner known per se e arranged through which the fuel is fed to the grate. Between the hopper c and .dem vault d a draw opening f is arranged through which the combustion gases pull and brush past the front wall of the boiler wall in the usual way. They are passed between the tubes of the boiler cc, advantageously a partition h. can be built in to force the smoke gases on the Wanda to swipe along g. According to the invention, the front outer wall c of the boiler walling be made as thin as possible. The hopper is here directly on the Fu3 attached to this wall. Vertical retorts open into this filling funnel k of any number, which are assembled with the wall g in such a way that they are honeycomb-like Lined up next to each other, leave open spaces between them after the boiler room. At the upper end, the retorts have a gas-tight insertion device l of any kind Art. On the front wall of each retort there can be vent nozzles m at different heights be arranged for the fractional discharge of the ascending gases ..
