Abstract: A combustion device includes a combustion chamber having an exhaust gas opening. The combustion chamber has a first region having a plurality of circular-segment-shaped cross-sections, which are parallel to each other and each have a circle centre point. A connection of the circle centre points lies substantially on an axis. A gas supply line is connected to the combustion chamber in such a way that a discharge point is formed, that the combustion chamber has a mixing region in the region of the discharge point for mixing gas supplied via the gas supply line with gas rotating in the combustion chamber, and that the discharge point is arranged on a bottom side of the combustion chamber in an operating position, wherein gas supplied via the gas supply line flows against the first region tangentially from below.

Abstract: A guide means of a centrifugal force separator or cyclone separator for separating at least one substance from a gaseous or liquid medium under the action of centrifugal forces has two or more baffle plates (2) with a radius which decreases from the center axis of the guide means, viewed in the direction of rotation of the medium. Between these baffle plates (2) entry openings (16) into the guide means are formed for the medium from which the substance has been largely removed into the guide means. There is a bottom plate (3) on the end of the guide means which projects into the interior of the device. To improve incident flow or inflow of the medium into the guide means, the bottom plate (3) in the area of the entry openings (16) has recesses (12).

Abstract: In a separating wheel for an air separator the radially outside ends of the separating wheel blades are tilted backwards in the direction of rotation of the separating wheel. In the area of the radially outside end of the separating wheel blades the front wall of the separating wheel blades which is viewed in the direction of rotation is tilted to the radial direction at a greater angle than the rear blade wall. Very good separating behavior is achieved by the dramatically inclined front wall of the separating wheel blades. The smaller tilt of the rear wall of the separating wheel blades with respect to the radial furthermore prevents the separated material from attaching to the rear wall of the separating wheel blades.

Abstract: A separator wheel for an air separator, through which separation air loaded with fine material flows through the separator wheel from the outside to the inside and in which the separation air loaded with fine material is discharged in an axial direction from separator wheel, includes at its periphery channels in axially different radial planes with different angles to the radial direction of the separator wheel, the angle of incline of the channels near an outflow end of the separator wheel being greater than the angle of incline of channels away from outflow end.

Abstract: A pneumatic sifter includes a feeder for supplying sift material, optionally with sifting air, to a rotationally symmetrical sifting chamber which surrounds a centrally disposed air outlet chamber, and a coarse particle discharge. In order to keep the flow resistance low as air enters into the air outlet chamber, guide vanes are provided in the air outlet chamber, which are spaced from each other at uniform angular distances and extend approximately over the axial extension of the sifting chamber.

Abstract: A baffle means (2) is provided at a dip pipe (1) which latter projects into the separating chamber of a facility for the separation of substance mixtures of a liquid or gaseous medium and a liquid or solid substance under the effect of centrifugal forces, the medium being discharged from the facility through this dip pipe. The baffle means (2) includes at least one baffle (3) having the shape of the shell of a truncated cone, the axis of curvature (4) of which extends in parallel to the longitudinal axis (5) of the dip pipe (1) and is offset with respect to this axis (5). By the baffle means (2), the medium is guided into the dip pipe (1) with simultaneous reconversion of the flow energy into pressure energy, there being imparted to the medium an acceleration oriented axially in the flow-off direction of the medium and an acceleration.

Abstract: A device for dust separation from flue gases produced during combustion of solid waste comprises a housing (1) wherein an untreated gas chamber (3) is arranged. Several cyclone separators (10) are provided in the untreated gas chamber (3); the untreated gas enters the housings (12) of these separators by way of a tangential raw gas inlet (13). Furthermore, a pure gas chamber (7) is located in the housing (1), separated from the raw gas chamber (3) by a partition (5). The pure gas exits from the cyclone separators (10) through pipes (14) penetrating the partition (5) into the pure gas chamber (7). The cyclone separators (10) each include a dip pipe (14, 15) respectively projecting from the top and from the bottom into the separating chamber (11) provided in the housing (12) of the cyclone separators (10). The raw gas chamber (3) is separated at the bottom from a dust-collecting chamber (17) by means of a partition (6).

Abstract: For the separation of at least one material from a liquid or gaseous medium, with a specific gravity different from the medium, the flowing mixture of material and medium is set into rotation about an axis oriented in parallel to its flow-off direction, the material is separated from the medium by centrifugal forces, and discharged separately from the purified medium. The velocity of the rotation of the mixture of material and medium is increased by an increasing reduction of the radius of the rotary movement. The medium is discharged from the device by means of mutually coaxially opposed dip pipes. An apparatus (10) for performing the process comprises a baffle (112) for producing the rotary motion of the introduced mixture in a separating chamber (113). The purified medium is withdrawn from the separating chamber (113) by way of mutually opposed dip pipes (114, 115), the cross section of which is smaller than that of the separating chamber (113).

Abstract: In a drive arrangement for the loading arms (5) of a loading ramp for a heading machine or longwall shearing machine, each loading arm (5) is rotatably supported in off-center position on a rotary disc (7) and extended beyond its axis of rotation (6) by guide arm (10) arranged so as to swivel around a bearing point on one end of a steering lever (11). The heading machine or longwall shearing machine has--for broadening its loading ramp--laterally outwardly swivellable parts (2) having arranged thereon, in a manner preventing angular movement, an arm (14) extending beyond the pivotal axis (4) of the extendible part (2). For automatic adaptation of the removal width of the loading arms (5) to the selected working width of the loading ramp, the other end of the steering lever (11) is hinged to the free end of the arm (14) connected with the outwardly swivellable part (2).
