Definitions

  • Thermal conversion of solid fuels e.g. most different types of coal, peat, hydrogenation residues, residual materials, waste, biomasses, and fly dust or a mixture of these substances is often performed under elevated pressure and at high temperature with the aim to generate a crude synthesis gas with a high content of energy and/or with a composition that is favorable for further chemical syntheses.
  • Feasible thermal conversion processes may for example be pressurized combustion or pressurized gasification according to the fluidized bed or flue stream process.
  • Porous elements preferably are comprised of sinter metal, but they may also be comprised of other porous media.
  • the use of porous materials entails some disadvantages in terms of process and operational technology:
  • German patent specification DE 41 08 048 C2 discloses gas feeder elements that are introduced into the cone-shaped part of a pressure pot in order to achieve a fluidization of the solid material bulk charge with the aim to bring about a pneumatic conveyance from out of the pressure pot.
  • tube elements equipped with bores to allow for gas feeding are mounted on the interior sides of the cone.
  • EP 348 008 B1 proposes to ensure a constant solid matter mass flow from a tank with a conical outlet by feeding gas through a central pipe inserted vertically from the top into the solid matter bulk charge near the outlet and in the conical tank section.
  • gas is supplied via the conical walls, said conical walls being designed and constructed as a porous medium.
  • WO 2004/085578 A1 discloses a sluice container providing gas feeder elements inside in the conical container section through which the container is brought to the target pressure.
  • the elements are provided with porous element through which the gas is supplied.
  • WO 89/11378 A1 proposes to feed gas by inserting porous elements in the cone of a silo in order to allow for an even and uniform flow of material.
  • the same aim is pursued by the gas feeding device disclosed in U.S. Pat. No. 4,941,779 A.
  • the difference lies in that the device described immerses into the bulk charge, supplies gas there partially in order to also ensure the most uniform possible flow of material from a drain port provided there.
  • porous elements are employed in order to feed gas into the bulk charge composed of fine particles.
  • US 2006/013660 A1 in detail describes a fluidizing cone including the required connecting flanges which is fastened to a tank. According to this description, the conical interior walls are made of a porous material.
  • CH 209 788 describes a reservoir tank for dust-like goods with a hopper terminating into a downcomer in which a thin layer of air migrates at the hopper wall towards the downcomer without approaching the center of the hopper, while air ascending through the center of the hopper forces the dust outwardly against the hopper wall, thus preventing a formation of bridges.
  • the inventive discharge cone solves this task in that
  • the slots are formed by laterally overlapping cone sectors.
  • the slots extend in oblique direction and that the gas exit side is spirally aligned both in tangential and in the direction of the exit aperture, i.e. that it also has a radial-vertical portion.
  • the slots are formed by sections overlapping one above each other in form of oblique cone sections.
  • the slots can be closed by cover metal sheets which have round or slit-shaped apertures.
  • the apertures may also have the shape of a nozzle jet.
  • the apertures are preferentially larger than the largest particle diameter of the solid matter in the discharge cone.
  • the thickness of the cover metal sheets can be so chosen that it is 3 times larger than the bore diameter in order to give the gas beam a specific direction.
  • the apertures can be provided at smaller distances than in the lower area of the slots.
  • the holes may have larger cross-sections in the upper area than in the lower area so as to be able to supply a gas stream which is related to the cone cross-sectional area and adapted to the relevant level.
  • exit tubes or exit nozzle jets may also be employed in other advantageous configurations, with it being possible to choose the spatial angles in which the gas beam enters into the discharge cone.
  • FIG. 1 shows a storage tank 1 with an inventive discharge cone 5 .
  • FIGS. 2 and 3 illustrate a discharge cone with slots extending in vertical direction.
  • FIG. 4 shows a variant with modified inlet apertures.
  • FIG. 5 illustrates a discharge cone with slots which have an oblique angle towards the center axis.
  • FIG. 1 shows a storage tank 1 with an inventive discharge cone 5 , into which the finely pulverized fuel 2 is transported pneumatically or gravimerically.
  • the gas 3 exits from the storage tank 1 via gas filter 4 , whereas the finely pulverized fuel gets into the storage tank 1 where it sinks down into the discharge cone 5 .
  • the gas 3 is comprised of the transport gas and of the gas which is displaced in the tank by the solid matter brought in.
  • the gas 3 is mainly comprised of displaced gas.
  • the discharge cone 5 encompasses a pressure jacket 6 which is charged with pressurized gas 7 .
  • the withdrawal 9 of the finely pulverized fuel is realized through the sluice 8 .
  • FIGS. 2 and 2 each show one discharge cone 5 with slots 10 which extend in vertical direction and from which the gas 3 streams out in tangential direction.
  • FIG. 2 also shows half the opening angle ⁇ of the discharge cone.
  • the slots are closed with metal sheets 11 into which bores 12 are inserted through which pressurized gas 7 from the pressurized jacket 6 can be introduced into the discharge cone 5 .
  • FIG. 3 shows slots 10 which viewed from the center line are concealed and have a projection 13 , the slots 10 shown in FIG. 2 are open.
  • FIG. 4 shows the variant illustrated in FIG. 3 , but with modified inlet apertures to reduce the high strains and stresses which the cone wall is exposed to due to the tangential outflow of the gas stream from the aperture in slot 10 .
  • the inlet apertures are so modified that the beam direction of the escaping gas jet can be spatially aligned. Constructively this can be achieved by executing the metal sheets 11 (not drawn in FIG. 4 ) in the slots 10 as very massive metal sheets and by providing for accordingly fine bores 12 which are inserted in defined angles into the metal sheets 11 , or by providing thin metal sheets 11 at which thin exit tubes or exit nozzle jets 14 are mounted which for example can be aligned by simple bending into the appropriate direction.
  • Such exit tubes or exit nozzle jets 14 are preferentially mounted flush on the conus inside, protruding on the side facing the exterior space so that the direction of beam can be aligned with simple means on the protruding side.
  • a Cartesian coordinate system is taken as the basis. Its point of origin lies in the piercing point, one vertical y-z plane of which extends in parallel to the cone center axis and the other vertical x-y plane of which intersects the cone center axis, and the third x-z plane of which represents the horizontal plane.
  • Contemplated in FIG. 4 are the angles of the axis of the exit tubes and/or exit nozzle jets 14 on the outside of the discharge cone where they are easy to measure in mounted state. The same applies analogously to the corresponding gas exit angles into the discharge cone.
  • the angle a lies between the projection 15 of the beam axis, which corresponds to the axis of the exit tubes or exit nozzle jets 14 , on the horizontal x-z-plane, and the tangent 16 , which rests on a horizontal section of the cone and extends through the point of origin of the coordinate system, between 0 and 45 degrees. Furthermore, the angle ⁇ lies between the beam axis which corresponds to the axis of the exit tubes or exit nozzle jets 14 , and the horizontal x-z plane in a range of 30 degrees upwards to 30 degrees downwards.
  • FIG. 5 shows another discharge cone with downwardly directed slots 10 which extend in spiral direction.
  • the slots 10 are also closed with metal sheets 11 into which bores 12 are inserted through which pressurized gas 7 from the pressurized jacket 6 can be introduced into the discharge cone 5 .
