Description
Füll- und Trockenschacht für-Schrägrostfeuerungen, dessen Gitterwände aus Schamottbalken und eisernen Platten bestehen Es ist bei Feuerungen bekannt, die nach dem Feuerraum gelegene Wand des Füllschachtes durch jalousieartig übereinanderliegende schräge Platten zu bilden, deren untere Kante an der Kohlenseite tiefer liegt als die äußere Kante der nächst unteren Platte an der Feuerseite.Filling and drying shaft for inclined grate firing, its mesh walls consist of fireclay beams and iron plates. the wall of the feed chute located after the combustion chamber by louvre-like superimposed on each other to form inclined plates, the lower edge of which is lower on the coal side than the outer edge of the next lower panel on the fire side.
Auch ist ein Trockenschacht für Schrägrostfeuerungen bekannt, dessen Vorder- und Rückwand derart mit schrägen Schlitzen versehen sind, daß nach dem Kohlenraum zu abfallende Gleitflächen entstehen, die im wesentlichen senkrecht übereinanderliegen, so daß die Böschungsflächen der Kohle an den Schlitzen für den Zutritt der Rostgase freiliegen.A drying shaft for inclined grate firing is also known, its Front and rear walls are provided with inclined slots that after the coal space sloping sliding surfaces are created which are essentially perpendicular to one another, so that the slope surfaces of the coal at the slots for the entry of the rust gases exposed.
Gemäß der Erfindung finden diese bekannten Einrichtungen Anwendung bei einem Trockenschacht für Schrägrostfeuerungen, in dem der Brennstoff durch rückkehrende Rostgase vorgewärmt wird, und zwar derart, daß Gitterwände mit Platten von j-förmigen Querschnitt verwendet werden und zur Bildung eines Innenkanals in versetzter Lage derart ineinandergeschachtelt sind, daß ein schlangenförmiger Weg für die durchströmende Rostgase entsteht.According to the invention, these known devices are used in the case of a drying shaft for inclined grate firing, in which the fuel is returned by returning Rust gases is preheated, in such a way that lattice walls with panels of j-shaped Cross-section are used and to form an inner channel in a staggered position are nested in such a way that a serpentine path for the flowing through Rust gases arise.
Auf diese Weise erfüllen die Gitterwände besser ihren Zweck, weil sich die Kohlen nicht in die Spalten zwischen den Platten hineinpressen, sich dort festlagern und in Form einer schlackenartigen Sinterung die Spalten allmählich verstopfen. Sie fördern auch den Trockenprozeß wegen des freien Zutritts der Rostgase zu den Böschungsflächen der Kohle. Die Zeichnung zeigt als Ausführungsbeispiel des Erfindungsgegenstandes schematisch einen _Füllschacht mit mehreren Begrenzungsrändern, die aus Schamottbalken und eisernen Platten bestehen und Absaugekanäle enthalten.In this way, the mesh walls serve their purpose better because the coals do not press themselves into the gaps between the plates, there and gradually clog the gaps in the form of a slag-like sintering. They also promote the drying process because of the free access of the rust gases to the Embankment areas of the coal. The drawing shows an exemplary embodiment of the subject matter of the invention schematically a _Füllschacht with several boundary edges, which are made of fireclay beams and iron plates and contain suction ducts.
Die innere Schachtwand besteht aus Schamottbalken c, die übrigen Begrenzungswände aus eisernen, im Querschnitt winkelförmigen Platten e, welche nach der Kohlenseite das gleiche Profil wie- die Schamottbalken haben.The inner shaft wall consists of fireclay beams c, the other boundary walls made of iron plates e, angular in cross-section, facing the coal side have the same profile as the fireclay beams.
Die schräge Fläche der in die Kohle keilförmig einspringenden Platten bewirkt ein Abwälzen der Kohle nach abwärts wie an den Stufen einer Treppe. Es kann sich in den waagerechten Spalten der Schachtwände keine Sinterung von Brennstoff bilden. Die Spalten können sich nicht verstopfen, gestatten aber eine ungehinderte Berührung der Kohle mit den Rostgasen, die zickzackförmig durch die Absaugekanäle hindurch vom Zug des Kamins abgesaugt werden.The inclined surface of the plates that protrude into the coal in the shape of a wedge causes the coal to roll downwards like on the steps of a staircase. It can There is no sintering of fuel in the horizontal gaps in the shaft walls form. The crevices cannot become clogged, but allow unhindered Contact of the coal with the rust gases, which zigzag through the suction channels be sucked through by the pull of the chimney.
