Definitions

  • the invention relates to a solid fuel gasification according to the preamble of the main claim.
  • Solid fuel gasification furnaces of the type mentioned are known, for example, from DE-PS 829 482.
  • This is a generator gas firing system with descending gasification, the actual firing area being partially surrounded by cooling air chambers and the cooling air flowing through flowing into the secondary heating surface to be connected in addition to the gases formed in the combustion chamber.
  • the cooling air chambers are arranged with the intention of making the generator as light as possible in order to avoid heavy shaft lining. This objective is achieved, however, by the effort in terms of the arrangement and design of the cooling air chambers, which, however, do not even cover the side flanks of the furnace. If this were the case, there would be an even greater effort.
  • the invention is accordingly based on the object of improving a solid fuel gasification of the type mentioned in such a way that, despite the use of refractory material, no bricking is required and this material is uncomplicated, i.e. can be placed in a casing without any brickwork measures and the refractory parts should be designed and assigned to each other in such a way that a conical ember bed results from which the gases flow freely upwards, then burn out completely and can then be fed to a secondary heating surface or afterburner chamber .
  • the space between the enclosure and the refractory parts can be filled with insulation material. But it is also possible to use the enclosure isolate it from the outside and at least design the side wall as a water-bearing double wall. For manufacturing reasons, all parts are preferably cylindrical or ring-cylindrical. With regard to the grate, a particularly advantageous embodiment, which is expedient for the proper operation of the furnace, is provided and will be explained in more detail.
  • a stationary grate 21 is provided centrally under the stump 10 in the end cover 11, the stump 10 is equipped with an ash clearing opening 22.
  • a rotating grate 23 (FIGS. 2, 3) is advantageously provided as the grate. Rotating elements, possibly connected to the rotating grate, can also be provided to counteract any bridging in the shaft if fine wood waste such as sawdust or wood shavings are to be burned. Because of the heat load in the ember bed area, however, such stirring elements are preferably introduced and actuated from above.
  • the formation of the stump or the arrangement of the enlargement 4 creates the shoulder 5 in the area of the ember bed, the upper stump 6 advantageously being designed with an inclination less than 45 °.
  • the free space 1 in the housing 2 can, but need not, be filled with insulating material.
  • the cylindrical side wall 2 ' can be designed in the form of a water-carrying double wall 15 and can be provided with flow and return connections 13, 14.
  • the housing 2 is then expediently given an exterior (not shown here) isolation.
  • the enclosure 2 is closed with a tightly attachable cover 18, which, as can also be seen, is at the same time the carrier of the upper filling shaft 3, into which the solid fuel can be introduced in a suitable manner (by hand or with automatic feed elements) through a filling opening 16 .
  • this opening 16 can also be designed as a smoke surge lock, but this is generally hardly necessary, since the carburetor is expediently equipped with an induced draft fan (not shown) behind the opening 8 or behind the secondary heating surface (not shown).
  • the upper, also provided with insulation 31 filling shaft 3 passes through the ceiling 8 with its lower edge 17 and thus forms the connection to the upper ring 19 made of refractory material, i.e. this edge 17 also serves as a centering and holder for the fire-ceramic parts.
  • the entire carburetor combustion system consists of three independent parts, which are easy to transport, assemble and disassemble, namely the enclosure 2, the fire-ceramic insert, which does not require bricking, and the ceiling 18 Filling shaft 3.
  • the grate is advantageously designed as a rotating grate 23 and is arranged at a distance from the lower shaft opening 24 of the solid fuel shaft and is suitably stored in the ash housing 12 located underneath, and advantageously adjustable in the axial direction, as indicated by a double arrow.
  • On the underside is the rotating grate 23 with at least one ash protruding into the ash housing 12 wing 25 and can thus coat an ash discharge opening 27 j arranged in the clearing area in the bottom 33 of the ash fall housing 12, below which, as shown, for example, a small ash discharge screw conveyor 30 can be arranged.
  • a temperature sensor 29 controlling the drive 28 of the rotating grate 23 is arranged in the lateral ash discharge area 27 of the rotating grate 23 and is connected to the drive 28 via a control element.
  • the lower edges 32 of the two clearing vanes 25 are arranged above the bottom 33 of the ash fall housing 12 at a distance which allows such axial adjustment of the rotating grate.
  • the remaining ash that remains is irrelevant, the only important thing is that no ash build-up can be built up in the ash fall housing 12 due to a lack of ash removal so that the arrangement area of the temperature sensor 29 can also be added, since this area is for the aforementioned temperature sensing must be kept clear.
  • the rotating grate is designed as a flat, upwardly converging cone 23 'and is provided with a horizontally extending annular surface 23 ", which is particularly important for the build-up and also the waste of the ash layer located in area 7 is advantageous.
  • the clearing vanes 25, of which four can of course also be arranged are in relation to the direction of rotation and radius of the rotary tes 23 against the direction of rotation set at an angle or curved, which ensures a transport thrust to the outside to the opening 27 '.
