摘要： An apparatus is described which serves for a pyrometallurgical processing of fine-grained solids suspended in high-oxygen gases, comprising a generally horizontally extending cylindrical vessel and a combustion shaft, which communicates with and vertically opens into the vessel which is provided with a gas outlet opening and with an opening for discharging molten material. An almost complete separation of the molten particles is effected in that the mouth of the combustion shaft tangentially opens into the vessel at the entrance of a spiral-shaped entrance passage, which opens into a discharge slot, which is formed in the shell of the vessel and which in the lower portion of the shell of the substantially cylindrical vessel extends substantially parallel to the longitudinal axis of the vessel.

摘要： An apparatus for producing ignitable solids-gas suspensions has a feeder for vertically feeding the solids-primary gas suspension, a secondary gas passage concentrically surrounding said feeder, and a stage for mixing both streams. In order to improve the igniting and melting of solids-gas suspensions in such apparatus, the feeder for the solids-primary gas suspension consists of a pressure relief vessel, which is provided with a tangentially extending supply line for supplying the solids-primary gas suspension, which supply line opens into said vessel in a substantially horizontal direction, and in that the pressure relief vessel is succeeded by two series-connected mixing stages which consist of venturi diffusers, the secondary gas passage concentrically surrounds the diffuser in the first mixing stage and the second mixing stage contains a flame-sustaining annular gas burner having fuel gas and oxygen nozzles arranged in alternation and surrounding the diffuser outlet, which is provided with a cooling chamber. The entire burner apparatus is mounted on the top rim of a vertical combustion shaft, which opens into a horizontal melting cyclone chamber.
