   Die Ausführung des Verfahrens wird durch die Fig. 1 und 2 der beiliegenden Zeichnung erläutert. In derselben bezeichnen a die mit dem Brenngut gefüllten, zu   Stössen   übereinander geschichteten Kapseln, b ist die Brennkammer eines Gasofens, in welcher die Kapselstösse reihenweise aufgestellt sind. Die   Flammengase   treten aus den vier in den Ecken befindlichen Feuer-   schächten   c aus, steigen zunächst senkrecht in die Höhe, wo sie in dem freien Raum unter der Decke expandieren, um dann parallel zur Längsachse der aus den einzelnen Kapseln a gebildeten Kapselstösse zu den im Boden befindlichen Abzugslöchern d zu gelangen.

   Die Beheizung erfolgt diskontinuierlich, d. h. so, dass eine frisch eingesetzte Kammer zunächst langsam auf die nötige Temperatur angeheizt und dann bis zur Beendigung der Reaktion auf dieser Temperatur erhalten wird, worauf man die Kammer abkühlen lässt und die einzelnen Kapseln entleert. 



   Die   Befeuerung   des Gasofens kann selbstverständlich auch in umgekehrter Richtung mit Sohlfeuer erfolgen, derart, dass die   F1ammengase   aus den im Boden befindlichen   Öffnungen d   austreten, zwischen den Kapselstössen parallel zur Längsachse derselben in die Höhe steigen und durch die Abzüge c austreten.

   The execution of the method is illustrated by FIGS. 1 and 2 of the accompanying drawing. In the same, a denotes the capsules filled with the material to be fired and stacked in piles, b is the combustion chamber of a gas furnace in which the piles of capsules are set up in rows. The flame gases emerge from the four fire shafts c located in the corners, first rise vertically upwards, where they expand in the free space under the ceiling, and then parallel to the longitudinal axis of the capsule joints formed from the individual capsules a to the im Drain holes located on the bottom d.

   The heating takes place discontinuously, i.e. H. so that a freshly inserted chamber is first slowly heated to the required temperature and then maintained at this temperature until the reaction has ended, after which the chamber is allowed to cool and the individual capsules are emptied.



   The gas furnace can of course also be fired in the opposite direction with a bottom fire, in such a way that the flammable gases exit the openings d in the bottom, rise between the capsule joints parallel to the longitudinal axis of the same and exit through the flues c.
