    摘要: A process for thermally treating fine-grained solids with high-oxygen gases at temperatures at which the solids can form molten and gaseous reaction products comprises carrying out the thermal treatment in a cyclone chamber and thereafter conducting the gases from the cyclone chamber into a horizontal or vertical cooling chamber. The process can be used for the roasting of sulfide ores, ore concentrates and other metallurgical intermediate products. The outlet of the cyclone chamber through which the gases are removed lies approximately along the axis and cooling is carried out in the cooling chamber such that the molten droplets contained in the gas stream entering the latter are cooled in free flight below their solidification point in the gas, i.e., do not contact the walls of the cooling chamber until they are solidified at least along their surfaces.

    摘要: Gases having a high SO.sub.2 content are catalytically reacted in a contacting zone having a plurality of series-connected contacting trays. A partial stream of partly reacted gases from the contacting zone containing SO.sub.3 is admixed with the SO.sub.2 containing gas before entering the first contacting tray. The gases are subjected to interstage cooling between contacting trays. At least a portion of the partly reacted gases is passed through an absorber prior to mixing with the feed stock gas having a high SO.sub.2 content. The rate at which SO.sub.3 is absorbed is increased in dependence on the loss of catalyst activity in the contacting zones such that the conversion of SO.sub.2 to SO.sub.3 in the contacting trays remains approximately constant.

    摘要: A method and apparatus for operating a gas turbine installation combustion chamber with liquid fuel, by means of which the NOX are similar to those for gaseous fuels. The liquid fuel (38) is evaporated in two steps in an evaporative reactor (12). The liquid fuel (38) is first atomized to a fuel vapor/liquid fuel mixture (61) by direct heat exchange with a first heat exchange medium (21). The evaporation of the remaining residue of the liquid fuel (38) takes place by indirect heat exchange with a second heat exchange medium (51). An evaporative reactor (12) is arranged which accommodates, at its inlet end, a dual-fluid nozzle (22) connected both to a liquid fuel line (19) and to a supply line (20) for a first heat exchange medium (21).

    摘要: A method of recovering fluorine, e.g. as hydrogen fluoride, from wastes of aluminum electrolysis furnaces, chemisorbents, adsorbents or absorbents, etc. in which the fluorine-containing material is subjected to pyrohydrolysis in an expanded fluid bed and the HF-containing gas is subjected to condensation or scrubbing for the removal of the HF therefrom. According to the invention, the exhaust gases from the fluidized bed are cooled by direct contact with solids which can be circulated in a separate cycle and are themselves cooled in a cooler, e.g. by contact with gas which is to be fed to the expanded fluidized bed. The circulated solids thus allow recovery of the sensible heat of the gas without diluting it.
