Abstract: A fluidizing plate is provided. The fluidizing plate generates a fluidization layer accommodating a dustlike bulk material, having a high operating temperature range and high permissible differential pressure relative to the thickness of the fluidizing plate, a support plate which carries the filter material and has through holes. Particular designs of the filter material feature metallic filtration fabric with or without support fabric, sintered metal, and sintered plastic, in each case with a filter fineness of 5 ?m to 1000 ?m. Particular designs of the fluidizing plate feature the disposition of a central through hole for the shaft of a stirrer mechanism, and an opening for the emptying of the fluidization vessel.

Abstract: A burner is provided for gasifying powdered fuel with a free oxygen-containing oxidant at temperatures up to 1900° C. and pressures up to 10 MPa. The burner includes a powder burner part having an oxidant channel and a powdered fuel channel, and a central pilot burner part. An annular channel for the outflow of an inert medium is arranged at the burner mouth between the pilot burner part and the powder burner part.

Abstract: A gas feed element is provided. In the gas feed element for feeding gas into a dust-like loose material having a high permissible differential pressure in respect of the thickness of the gas feed element and a high operating temperature range, a support plate having openings (holes) is arranged on the side of the filter material facing the gas flow and on the side of the filter material facing away from the gas flow. The gas feed element permits rapid pressurization of a pressure vessel containing a stock of coal dust. Particular configurations of the filter material are provided by metallic filtration mesh with or without support mesh, sintered metal and sintered polymer, in each case having a filter fineness of from 5 ?m to 1000 ?m.

Abstract: A method of measuring a solid matter mass flow during conveying of solid matter-gas suspensions in tubular conduits, particularly during conveying in a dense stream with high pressure, comprises the steps of changing in a pulse mode a solid matter concentration of a solid matter-gas suspension at one location of the conduit through which the suspension flows, continuously measuring a solid matter concentration of a solid matter-gas suspension or a value corresponding thereto at two measuring locations downstream of the first-mentioned changing location and spaced from one another in the conduit, determining a difference between time points at which a difference of the solid matter concentration or the corresponding value is indicated after one another at the measuring locations downstream of the first-mentioned changing location and spaced from one another, determining a per-unit-time average value of the solid matter concentration of the solid matter-gas suspension in a conduit portion corresponding to the m

Abstract: A cold sheet metal forming apparatus in which the forming rolls are held at each end by bearing housings in each case held by screw-threaded rods engaging the housings and being secured directly to a main supporting frame.Such an arrangement leaves additional room between adjacent pairs of rolls and a second set of rollers are nested between the first set also with the simplified support arrangement at each end of each roll so as to allow a second rolling line to be kept in position and available for prompt use without as has hitherto been the case the necessity to change rollers.
