    摘要: A process of gasifying fine-grained solid fuels for the production of a product gas that contains hydrogen, carbon oxides and methane comprises a treatment with steam, oxygen and/or carbon dioxide in two interconnected gasifying stages under a pressure in the range from 2 to 150 bars and at temperatures of 500.degree. to 1500.degree. C. In the first gasifying stage, the fuel is gasified in a circulating fluidized bed by a treatment with gasifying stage. The residual solids which become available in the first gasifying stage are fed to the second gasifying stage and are virtually completely gasified therein, except for residual ash, by a treatment with a gasifying agent which includes oxygen. At least one-half of the product gas from the second gasifying stage is fed to the first gasifying stage and used as fluidizing fluid therein.

    摘要: A method of and apparatus for carrying out an exothermic process in which a combustible-containing solid (e.g. coal shale, pyrite or limestone in combination with fuel oil) are burned in a fluidized-bed reactor with primary and secondary streams of oxygen-containing combustion-sustaining gas (in a volume ratio of 1:20 to 2:1) supplied at different levels so that the primary gas acts as the fluidizing gas. The gas velocities and rate of gas feeds are controlled to provide a mean suspension density above the secondary gas inlet of 10 to 40 kg/m.sup.3. The major portion of solid feed is introduced into the space below the secondary gas inlet which is maintained substantially free of internal fixtures and the effluent gases are separated from the entrained solids which are recycled to the bed. Solids withdrawn from the bed are cooled in a fluidized-bed cooler and the temperature of the bed is maintained constant by the controlled recirculation of cooled solids thereto from the cooler. The gas heated in the cooler is fed to the bed as the secondary gas.

    摘要: Carbonaceous material, preferably coal or like finely divided solids with a mean particle diameter of 30 to 250 microns, is burned to produce steam in a fluid-bed furnace having a lower free space without internal fixtures and provided above this free space with internal cooling surfaces. A secondary-gas inlet introduces the secondary gas so that the volume ratio of fluidizing gas to secondary gas ranges from 1:20 to 2:1 at a location above the fluidizing-gas and fuel inlets but below the internal cooling surfaces, the gas velocity of the several gases being adjusted so that the mean suspension density of the solids above the secondary-gas inlet is 15 to 100 kg/m.sup.3. Approximately stoidiometric conditions are maintained with respect to the oxygen in the gases introduced and the carbonaceous material and solids are recycled to the bed after being separated from the gases emanating therefrom.

    摘要: A method and apparatus are provided for aiding diagnosis of an object showing a disorder and for selecting a finding characterising the state of the object. Each finding is described as a visual pathology by a severity, a symptom constellation of multiple symptoms and by a graphic representation of the symptom constellation. A dialog-based, visual modelling of the state of the object is provided wherein the state of the object is modelled by a current symptom constellation represented by a symbol. The resulting, current object image is immediately graphically output on the display device. Following each case of modification a comparator immediately compares the current symptom constellation against the symptom constellations of stored findings and updates the list of findings of potentially applicable findings. A list of suggestions for examining further symptoms is output, sorted by their differentiation so as to interactively facilitate diagnosis.
