    • A novel kiln with overlying beds arranged about a central hollow shaft carrying rabble arms attached thereto and with alternate apertures formed in the floors between adjacent stories adjacent the hollow shaft and adjacent the periphery of the floor and with treatment gases being supplied through such orifices in a direction opposite to the direction in which the material moves through a furnace and further providing hot gas feed conduits located in the walls of the furnace in one or more stories and directed in a generally tangential direction relative to the story floors.
    • 一种具有覆盖床的新型窑,其布置在中央空心轴周围,所述中空空心轴承载着连接到其上的钻石臂,并且具有形成在邻近中空轴并邻近地板周边的相邻故事之间的地板中的交替孔,并且处理气体通过这些孔 方向与材料移动通过炉子的方向相反,并且进一步在一个或多个故事中提供位于炉壁中的热气体供给管道,并相对于故事楼层沿大致相切的方向引导。

    • A process of smelting a sulphidic copper ore concentrate comprising introducing and partially roasting the sulphidic copper ore concentrate in a whirling layer roasting furnace, separating hot roasting gases from the roasting furnace, mixing enrichment oxygen with the roasting gases, joining and mixing into a smelting flame combustible gaseous fuel and the oxygen enriched separated hot roasting gases, directing the smelting flame from one side of a reverberatory furnace over the top of a copper matte, continuously passing the partially roasted concentrate from the roasting furnace through the heating zone in the reverberatory furnace and there smelting the partially roasted ore and heating the copper matte by the heat from the flame, generating in the heating zone by virtue of the flame an oxidizing atmosphere of such high temperature and oxygen content that sulphur from the molten sulphidic copper is converted into an exhaust gas of high SO.sub.2 content, and exhausting the exhaust gas from the opposite side of the reverberatory furnace from the introduction of the flame.
