Description
Brennstoffaufgabeeinrichtung für Feuerungsroste Die Erfindung hat die Vervollkommnung einer Brennstoffaufgabevorrichtung für Feuerungsroste nach dem Patent 891903 zum Gegenstand. Bei dieser Brennstoffaufgabeeinrichtung wird die Verteilung des Brennstoffes im Rosttrichter mit Hilfe einer feststehenden Einfüllschurre od. dgl. durch eine im Rosttrichter angeordnete Verteilerschnecke bewirkt, welche von einem sich mitdrehenden, an beiden Enden verschlossenen und mit über seine ganze Länge ;reichenden Schlitz versehenen Rohr umhüllt ist. Fuel feed device for furnace grates The object of the invention is to perfect a fuel feed device for furnace grates according to patent 891903. In this fuel feeder, the fuel is distributed in the grate funnel with the help of a fixed filling chute or the like by a distribution screw arranged in the grate funnel, which is encased by a rotating tube that is closed at both ends and provided with a slot that extends over its entire length .
Vielfach besteht die Notwendigkeit, Feuerungsroste mit verhältnismäßig feuchten Brennstoffen zu beschicken, welche dazu neigen, sich an den Wandungen der Beschickungseinrichtung anzusetzen, was zu Störungen Anlaß geben kann. Durch die Erfindung wird dieses Ansetzen verhindert, indem die Verteilerschnecke bzw. das dieselbe umfassende Rohr oder auch beide Teile durch ein beliebiges Heizmittel (z. B. Abdampf, Heißluft, Rauchgase usw.) beheizt werden. Vorteilhaft wird dabei die Verteilerschnecke hohl ausgeführt, und an Stelle eines Rohres werden zwei ineinanderliegende Rohre verwendet, so daß das Heizmittel durch den verbleibenden Hohlraum geleitet werden kann, wobei gegebenenfalls innerhalb der Hohlräume Rippen angeordnet sein können.In many cases there is a need to use furnace grates with proportionately to charge moist fuels, which tend to stick to the walls of the To set the charging device, which can give rise to malfunctions. Through the Invention, this attachment is prevented by the distribution screw or the the same comprehensive pipe or both parts by any heating means (e.g. B. exhaust steam, hot air, flue gases, etc.) are heated. The The distribution screw is made hollow, and instead of one tube, two nested Pipes used so that the heating medium passed through the remaining cavity can be, with ribs optionally being arranged within the cavities can.
Durch die Erfindung wird eine gewisse Vortrocknung des Brennstoffes erreicht, so daß ein Ansetzen in der ummantelten Verteilerschnecke verhindert wird. Außerdem ist es auch für die Verbrennung von Vorteil, wenn der Brennstoff leicht vorgetrocknet aufgegeben wird.The invention enables the fuel to be pre-dried to a certain extent reached, so that a build-up in the jacketed distributor screw is prevented. Besides, it is also great for burning an advantage if the The fuel is fed in slightly pre-dried.
