Description

Füll- und Trockenschacht für Schrägrostfeuerungen, in dem der Brennstoff durch rückkehrende Rostgase vorgewärmt wird Die Erfindung bezieht sich auf einen Füll-und Trockenschacht für Schrägrostfeuerun-(ren, in dein der Brennstoff durch rückkehrende Rostgase vorgewärmt wird. In dein Schacht soll nach der Erfindung die Kohle. bevor sie den Rost erreicht, in wirksamer Weise aufbereitet und dadurch der Brennvorgang auf (lern Rost und gleichzeitig das Gesamtergebnis der Feuerung verbessert werden.Filling and drying shaft for inclined grate firing, in which the fuel is preheated by returning rust gases. The invention relates to a Filling and drying shaft for inclined grate fires, in which the fuel flows through returning rust gases is preheated. According to the invention, the Money. before it reaches the grate, processed in an effective manner and thereby the Burning process on (learns the rust and at the same time improves the overall result of the firing will.

Erreicht wird dieser Zweck dadurch, daß der Kohlenschacht aus mehreren mit wechselnder Neigung in größeren Abständen übereinander angeordneten Rutschflächen besteht, (legen nach dem Feuerraum zu gelegene Flüchen offene Nischen bilden, in denen die im Zickzack oder in einer Schlangenlinie von oben nach unten sich wälzende Kohle an ihren freien Böschungsflächen mit den rückkehrenden Rostasen unmittelbar in Berührung kommt. Dabei lagern sich die von den rückführenden Rostgasen getragenen glühenden Flugkoksteilchen auf der wandernden Kohlendecke ab und werden mit der wandernden Kohlendecke in das Innere der Kohlenmasse hineingezogen, so daß sie derer. Aufbereitung wirksam unterstützen.This purpose is achieved by the fact that the coal shaft consists of several sliding surfaces arranged one above the other with changing inclination at larger intervals consists, (place curses facing the firebox and form open niches in those rolling in a zigzag or in a serpentine line from top to bottom Coal on its free slope surfaces with the returning rusts immediately comes into contact. The rust gases carried by the returning rust gases are stored in the process glowing flycoke particles on the migrating coal cover and become with the wandering coal cover drawn into the interior of the coal mass, so that they. Effective support for reprocessing.

Ein Ausführungsbeispiel 'des Erfindungsgegenstandes zeigt die Zeichnung.The drawing shows an exemplary embodiment of the subject matter of the invention.

Die in größerer Anzahl vorgesehenen, den Kohlenschacht nach dein Feuerraum begrenzenden Schamottebalken sind bei dein neuen Füll- und Trockenschacht durch drei schräge Schamottedecken I, 2. 3 ersetzt, die in einem Winkel von etwa 3o° geneigt sind und senkrecht untereinander stehen. Der senkrechte Abstand dieser Schamottedecken ist so groß, daß der Schlund, den sie nach dem Feuerraum bilden. etwa I.5 m beträgt. Gegenfiber den nach dem Feuerraum offenen Schlünden sind an der Rückseite des Schachtes schräge Rostflächen 4., 3 und 6 mit entgegengesetzter Neigung angeordnet. Durch die winklig zueinander versetzten Schaniotteflächen I, 2. 3 und Rostflächen 4.. ; und h wird die Kohle gezwungen, sich im Zickzack oder in einer Schlangenlinie im Schacht von oben nach unten zu wälzen und zu mischen. Die Schamotteflächen z, 2, 3 bilden nach dem F euerrauin hin offene Nischen a, L), c, in denen sich die frei rieselnde Kohle in einem bestimmten Böschungswinkel anstaut.The ones provided in larger numbers, the coal shaft after your combustion chamber delimiting fireclay beams are through with your new filling and drying shaft three sloping pubic ceilings I, 2. 3 replaced, which inclined at an angle of about 3o ° and are perpendicular to each other. The vertical distance between these pubic ceilings is so big that the throat they form after the furnace. is about 1.5 m. Opposite the gullies that are open after the firebox are on the back of the shaft inclined grate surfaces 4., 3 and 6 arranged with opposite inclination. By the angularly offset scaffold surfaces I, 2. 3 and grate surfaces 4 .. ; and h the coal is forced to zigzag or in a serpentine line to roll and mix in the shaft from top to bottom. The chamotte surfaces z, 2, 3 form open niches a, L), c after the fire, in which the damming freely flowing coal at a certain angle of slope.

In diesen Nischen fangen sich die rückheführten Rostgase und geben ihre Wärme durch unmittelbare Berührung an die' Kohlendecke ab.The returned rust gases are caught in these niches and are released their heat from direct contact with the 'coal ceiling.

Die unendlich. vielen,-von den rückströinenden Rostgasen mitgeführten glühenden Flugkoksteilchen fangen sich in den 'Nischen a, b. c auf der wandernden Kohlendecke. reichern sich dort an und werden mit der wandernden Kohlendecke in das Innere der Kohlenmasse hineingezogen.The infinite. many, - carried along by the backflowing rust gases glowing fly coke particles are caught in the 'niches a, b. c on the migratory Coal ceiling. accumulate there and become in with the moving coal cover pulled the inside of the coal mass into it.

Infolge der großen Weite der sieh bildenden Schlünde. .welche die Übertragung der Wärme der'Rostgase durch unmittelbare Berührung auf Böschungsflächen von über I Meter ermöglicht, und durch das in großem Maße vor sich gehende Fangender Glühteilchen wird.die Kohle hochwertig bereits innerhalb des Schachtes aufbereitet.As a result of the great breadth of the gullies that form the sight. .those who Transfer of the heat from the rust gases through direct contact with slope surfaces of over 1 meter made possible, and by the large number of catchers going on Incandescent particles are processed to a high quality within the shaft.
