Description

Beschickungsvorrichtung für Wanderrostfeuerung Gegenstand der Erfindung ist eine Beschikkungsvorrichtung für Wanderrostfeuerungen, äie mit einer im Rosttrichter quer zur Beschickungsvorrichtung eingebauten Verteilerschnecke versehen ist, die den in der Mitte zugeführten Brennstoff gleichmäßig nach den Seiten verteilt.Charging device for traveling grate firing is the subject of the invention is a loading device for traveling grate firing, aie with one in the grate hopper transversely to the loading device built-in distribution auger is provided, which distribute the fuel fed in the middle evenly to the sides.

Um Magerfeinkohle ohne zu stariken Durchfall des feinen Brennmaterialä durch die Rostspalten - am vorderen Rostende verfeuern zu können, den großen Widerstand in der Brennstoffschicht für den Eintritt der Prellluft wesentlich zu verringern und die Entgasung des feinen Brennstoffes durch die nach der Verdampfung des Wässers sich bildenden Kanälchen auf dem Rost zu erreichen bzw. zu beschleunigen, ist es bekannt, die Feinkohle, bevor dieselbe auf den eigentlichen Wanderrost gelangt, gut anzufeuchten. Die Anfeuchtung des Brenjnstoffes muB jedoch, nachdem derselbe die Bunkerauslaufrohre passiert hat, erfolgen, da die Anfeuchtung verhältnismäßig stark vorgenommen werden muß und der nasse Brennstoff in den Bunkerrohren in sehr vielen Fällen nicht rutschen würde. Zur Erreichung einer gleichmäßigen Anfeuchtung erfolgt diese gemäß der Erfindung in einem dem Rosttrichter vorgeschalteten, den Bunkerauslauf aufnehmenden Mischtrog, in welchem durch drehbare Schaufeln der aus dem -Bunker ausfallende Brennstoff unter gleichzeitiger Mischung mit einem Anfeuchtmittel zum Rosttrichter gefördert wird. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In order to use lean coal without excessive diarrhea using the fine fuel through the grate gaps - to be able to burn at the front end of the grate, the great resistance to reduce significantly in the fuel layer for the entry of the baffle air and the degassing of the fine fuel by the after evaporation of the water It is important to reach or accelerate the small canals that are forming on the grate known, the fine coal before it reaches the actual traveling grate, moisten well. The moistening of the fuel must, however, after the same has passed the bunker outlet pipes, since the humidification is proportionate must be made strong and the wet fuel in the bunker pipes in very would not slip in many cases. To achieve even moistening this takes place according to the invention in an upstream of the grate funnel, the Bunker outlet receiving mixing trough, in which by rotating blades the The fuel falling out of the bunker is mixed with a moistening agent at the same time is conveyed to the grate funnel. In the drawing is an embodiment of the Invention shown.

Es zeigt Abb. i eine Seitenansicht teilweise im Schnitt, Abb. z eine Vorderansicht teilweise irn Schnitt. Die trockene- Magerfeinkohle gelangt durch das Bunkerauslaufrohr e in den Mischtrog a und wird hierin unter gleichzeitiger Anfeuchtung durch das durch die Rohrleitung b zugeführte Feuchtmittel durch Schaufeln c nach rechts und links in den Rosttrichter befördert: Um nun ein Leerbrennen des Wanderrostes an den Seiten zu verhüten, wird im eigentlichen Rosttrichter eine besondere Verteilerschnecke h angeordnet. Der Antrieb der Schaufeln in dem Mischtrog kann entweder durch einen besonderen Antrieb oder vom Rost aus erfolgen.It shows Fig. I a side view partially in section, Fig. Z a Front view partly in section. The dry lean coal gets through the bunker outlet pipe e into the mixing trough a and is here under simultaneous Moistening by the dampening solution supplied through the pipe b by means of shovels c conveyed to the right and left into the grate funnel: To prevent the Preventing traveling rust on the sides becomes a special one in the actual grate funnel Distribution screw h arranged. The drive of the blades in the mixing trough can either by a special drive or from the grate.
