Description

Schrägrostfeuerung mit hinter- und untereinander, entgegengesetzt geneigt angeordneten Einzelrosten Die Erfindung betrifft eine Schrägrostfeuerung mit hinter- und untereinander, eiltgegengesetzt geneigt angeordneten Einzelrosten. Solche Rostfeuerungen sind an sich bekannt. Erfindungsgemäß werden über den Linzelrosten Feuergewölbe derart angebracht, daß die Verbrennungsgase vom, unteren, durch Rost und Gewölbe gebildeten Verbrennungsraum durch den vom oberen Rost frei herabfallenden Brennstoff streichen müssen. Hierdurch wird eine erheblich kräftigere und restlosere Verbrennung als mit den bekannten Rostanordnungen erzielt.Inclined grate firing with one behind the other and one below the other, in opposite directions inclined individual grates The invention relates to inclined grate firing with individual grids arranged one behind the other and one below the other, inclined in rapid opposition. Such grate furnaces are known per se. According to the invention are over the Linzelrosten Fire vault placed in such a way that the combustion gases from the, lower, through grate and vault formed by the combustion chamber falling freely from the upper grate Have to cut fuel. This makes a considerably stronger and more complete one Combustion than achieved with the known grate arrangements.

Auf der Zeichnung ist der neue Rost in einem Ausführungsbeispiel dargestellt.In the drawing, the new grate is shown in one embodiment.

Der Rost besteht aus zwei hinter- und untereinander. entgegengesetzt geneigt angeordneten Einzelrosten mit in waagerechter Ebene verschiebbaren Stufen i, 2, deren Bewegung (zweckmäßigerweise gegenläufig) durch Zugstangen 3, 4 in irgendeiner zweckentsprechenden Art und Weise bewirkt wird. Die übliche Unterwindleitung gabelt sich in zwei Zweige 5, 6, von denen der obere Zweig 5 unter der oberen Roststufe i und der untere Zweig ö unter der unteren Roststufe 2 mündet. Anschließend an die untere Roststufe 2 ist ein kleiner Planrost 7 für den Ausbrand vorgesehen, der um einen waagerechten Zapfen 8 drehbar ist und mittels eines Handhebels 9 verstellt werden kann.The grate consists of two one behind the other and one below the other. opposite inclined individual grids with steps that can be moved in a horizontal plane i, 2, the movement of which (expediently in opposite directions) by means of tie rods 3, 4 in any is effected in an appropriate manner. The usual underwind line forks into two branches 5, 6, of which the upper branch 5 is below the upper grate step i and the lower branch ö opens under the lower grate step 2. Subsequently to the Lower grate level 2, a small plan grate 7 is provided for the burnout, which is around a horizontal pin 8 is rotatable and adjusted by means of a hand lever 9 can be.

Zwischen der oberen Roststufe i und der unteren Roststufe :2 ist ein Schamottgewölbe io derart angebracht, daß zwischen dieseln Gewölbe io und der unteren Roststufe 2 eine Verbrennungskammer i i entsteht, welche mittels Pendelklappen 12 abschließbar ist. über der oberen Roststufe i befindet sich ein Schamottgewölbe 13 sowie zwischen diesem und der oberen Roststufe i eine obere Verbrennungskammer 1q..Between the upper grate stage i and the lower grate stage: 2 a fireclay vault io is attached in such a way that a combustion chamber ii is created between diesel vaults io and the lower grate stage 2, which can be locked by means of pendulum flaps 12. Above the upper grate step i there is a fireclay vault 13 and between this and the upper grate step i an upper combustion chamber 1q ..

Der auf der oberen Roststufe i liegende Brennstoff wird bei der Vorwärtsbewegung dieser Roststufe abgeworfen, und der glühende Brennstoff fällt frei unter gleichzeitiger Umkehr der Schüttung auf die untere Roststufe 2. Von dieser gelangt derBrennstoff zum Schlackenrost 7, von welchem die Schiacre durch die Pendelklappe i? in den Aschentrichter fällt, Durch den freien Fall des Brennstoffes von der ersten Stufe zur zweiten Stufe werden Kohle und Schlacke innig geinischt, der Brennstoff wird also aufgelockert und brennt besser. Durch entsprechende Beines'sung von Hubzahl und Hubgröße der Roststufen kann man die Stärke der Brennstoffschicht entsprechend dem regelbaren Unterwinddruck beliebig einstellen.The fuel lying on the upper grate step i is in the forward movement thrown off this grate stage, and the glowing fuel falls freely under simultaneous Reversal of the bed to the lower grate level 2. The fuel arrives from this to the slag grate 7, from which the Schiacre through the pendulum flap i? into the ash funnel falls, By the free fall of the fuel from the first stage to the second stage coal and slag are intimately mixed, so the fuel is loosened and burns better. By appropriately considering the number of strokes and the stroke size of the Grate levels you can adjust the thickness of the fuel layer according to the adjustable Adjust the negative wind pressure as required.

Die sich oberhalb der unteren Roststufe 2 entwickelnden'Flammengasewerden auf ihrem Wege zum Feuerraum 15 durch die untere Verbrennungskammer i i, den frei fallenden glühenden Brennstoff und die obere Verbrennungskammer 1q. gepreßt. Infolgedessen kann auf der unteren Roststufe 2 die Brennstoffschicht stets so dünn gehalten werden, da.ß dieser Rostteil für sich mit viel Luftüberschuß arbeitet. Dieser Umstand beeinträchtigt den Verbrennungsprozeß in keiner Weise, da die gesamte Gasmenge mitsamt dem Luftüberschuß durch den frei fallenden glühenden Brennstoff hindurchstreicht und auf diesem Wege eine kräftige Verbrennung stattfindet.The flame gases developing above the lower grate level 2 will be on their way to the combustion chamber 15 through the lower combustion chamber i i, the free falling glowing fuel and the upper combustion chamber 1q. pressed. Consequently the fuel layer on the lower grate step 2 can always be kept so thin that that this grate part works with a lot of excess air. This fact affects the combustion process in no way, since the entire amount of gas including the excess air through the freely falling glowing fuel and in this way a vigorous burn takes place.
