An injector (12) for sucking in environmental air and for injection into the combustion chamber (12) of a torch burner (11) by means of a driving fluid (14) standing under excess pressure, has an air induction opening (15), a flow channel (16) and injection openings (17) through which the driving fluid (14) is blown into a mixing region (19) where it mixes with induced air. The flow channel (16) has a diffusor region (18) ajoining the mixing region (19) in the flow direction and has an outlet opening (20) for the mixture of air and driving fluid. In accordance with the invention, injection openings (17) open into a dead flow space (22) from which spray jets (23) are directed into the mixing region (19).

A high-pressure hot separator for the separation of an overhead product from a process of high-pressure hydrogenation of coals, tars, crude oils, whose distillation and extraction products or similar carbon-containing feedstock such as heavy oils, low-temperature carbonization oils, extracts of heavy oil sands and the like, is downstream from the bottom phase reactors of the high-pressure hydrogenation. The separator is constructed from a vertically erected cylindrical pressure jacket having an upper cover, a lower cover, an inside adjacent thermal insulation member and a cylindrical wall insert. The overhead product is separated into a gas/vapor phase and a bottom product. A cyclone separator is installed in the gas/vapor space of the hot separator for improvement of the separation function.

A hydrocyclone has a separating part A with a diameter which toward its outlet end for the heavier fraction decreases gradually from a diameter 2 R.sub.a, with the radius being subject to the formula:

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.
