Description

Schräg- oder Treppenrostfeuerung mit vorgebautem Trockenschacht, in dem der Brennstoff durch rückkehrende Rostgase vorgewärmt wird. Die Erfindung löst die Aufgabe, bei Feuerungen mit vorgebautem Trockenschacht den Brennstoff durch zum Trockenschacht zurückgeführte hochwertige Feuergase vorzutrocknen, um eine lückenlose Verbrennung auf möglichst kleiner Rostfläche zu erhalten und gleichzeitig die bei der Vortrocknung entstehenden schädlichen Schwelgase und Wasserdämpfe selbsttätig abzusaugen.Inclined or step grate firing with a pre-built drying shaft, in which the fuel is preheated by returning rust gases. The invention solves the task of getting the fuel through in furnaces with a pre-built dry shaft to pre-dry high-quality fire gases returned to the drying shaft in order to ensure a seamless To maintain combustion on the smallest possible grate area and at the same time the harmful carbonization gases and water vapors generated during the pre-drying process suck off.

Dieser Zweck wird gemäß der Erfindung dadurch erreicht, daß der durch zwei Stehroste begrenzte Trockenschacht durch zwei zwischen diesen gegeneinander verstellbar eingebaute Stehroste in zwei hintereinanderliegende und von den Heizräumen beheizte Brennstoffschächte unterteilt ist.This purpose is achieved according to the invention in that the by two standing grids bounded by a dry shaft between these against each other adjustable built-in standing grids in two one behind the other and from the boiler rooms heated fuel shafts is divided.

Die Heizräume stehen am unteren Ende mit dem Fuchs der Feuerung in Verbindung. Die zur Vortrocknung des Brennstoffes dienenden hochwertigen Feuergase werden den Trockenräumen im oberen Teile durch in den Feuerungs- oder Zwischenwänden vorsehene Kanäle zugeführt, und das Gemisch von Feuergasen und Schwelgasen wird im unteren Teile der Trockenräume drosselbar durch den Zug des Kamins abgesaugt.The boiler rooms are at the lower end with the fox of the furnace in Link. The high-quality fire gases used to pre-dry the fuel are the drying rooms in the upper part through in the furnace or partition walls Provided channels are supplied, and the mixture of fire gases and carbonization gases is suctioned in the lower part of the drying rooms can be throttled by the pull of the chimney.

Ein Ausführungsbeispiel zeigt die Zeichnung im Längsschnitt (Abb. i) und im Grundriß (Abb. z).The drawing shows an exemplary embodiment in longitudinal section (Fig. i) and in plan (Fig. z).

Der Trockenschacht hat zwei äußere Steh, roste a und zwei innere senkrechte Stehroste b. Letztere beiden sind mit einem( winkelförmigen Beschickungsblech c gelenkig verbunden und mittels auf Schienen laufenden Rollen d von außen gegeneinander verstellbar. Die inneren Stehroste b bilden innerhalb der Kohle den Vortrocknungsraume e, außerdem umgeben den Füllschacht außen und innen die Vortrocknungsräume f und f l. The drying shaft has two outer standing grids a and two inner vertical standing grates b. The latter two are a (angular caul c hingedly connected, and means mounted on a track rollers d adjustable from outside against each other. The inner floor grates b form within the coal to Vortrocknungsraume e, also surround the hopper outside and inside f the Vortrocknungsräume and f l.

In die drei Räume e und f und f i münden Kanäle g, h, h1, welche im Mauerwerk bzw. in den Zwischenwänden der Feuerung angeordnet sind und dazu dienen, diejenigen hochwertigen Feuergase, welche infolge kinetischer Energie in diese gelangen, zum Trockenschacht zu leiten. Diese Feuergase bestreichen die vier Roste a und b von oben nach unten und erwärmen dabei den Brennstoff an vier großen Flächen des Schachtes, wodurch eine gute Trockenwirkung erreicht wird. Am unteren Ende der Räume e und f und f 1 wird das Gemisch von Schwelgasen und Feuergasen mittels bekannter, nicht dargestellter Mittel durch den Zug des Kamins abgesaugt.Channels g, h, h1 open into the three rooms e and f and fi, which are arranged in the masonry or in the partition walls of the furnace and serve to guide the high-quality fire gases that get into them as a result of kinetic energy to the drying shaft. These fire gases coat the four grids a and b from top to bottom and heat the fuel on four large surfaces of the shaft, which results in a good drying effect. At the lower end of the rooms e and f and f 1, the mixture of carbonization gases and fire gases is sucked off by means of known means, not shown, by pulling the chimney.
