Definitions

  • the invention relates to a device for arranging and storing Rusting, especially grate bars or grate plates especially for feed grates in incineration plants (e.g. waste incineration plants).
  • a moving grate usually consists of fixed and movable ones Rows of grate bars. Air is generally supplied for combustion, which is about the grate and through the grate into the combustion chamber. For Air volume regulation must therefore be sealed in the combustion chamber. Next a seal on the underside of the grate, the grates must also close to Side walls are sealed, especially with regard to the Cross expansion of the rows of grate bars when exposed to heat.
  • DE 41 19 405 C1 describes an incinerator with a sliding grate Grate bars are known in which the individual grate bars are connected to one another and the outer grate bar on the fixed grate bar support with a Driver is coupled to a side plate with thermal expansion shifted towards the furnace wall.
  • the side plate consists of essentially from a wear plate and a transition angle and is positively connected to the grate bars by the driver who is on the outer grate bar is screwed tight.
  • the construction of the side plate has the advantage that Transverse expansion or contraction by heat respectively Cooling load the necessary tightness of the furnace remains.
  • the construction offers the sliding Storage of the carrier on the grate axis (4) and fixation on the Wear plate (2) the simple solution, a squeeze between Row of grate bars and wear plate or side wall effectively prevent.
  • That the carrier (3) as at least partially the cross section of the Rust axis (4) comprehensive profile is formed, has the advantage that Tilting between the grate and side wall can be avoided and a sufficient guidance of the grate bars or the support on the grate axis (4) is guaranteed.
  • the carrier (3) as a half-shell on a cylindrical Grate axis (4) can compensate for wear on the grate bar.
  • the driver (7) on a carrier (3) takes, for example, in the event of contraction the grate over the side grate bar (1) the wear plate (2) and thus receives the Seal between grate and side wall. It also does not apply a direct coupling between the side grate bar (1) and Wear plate (2) for example by screwing, which can cause the rows of grate bars to fold up.
  • the arrangement of one or more grate bars (5) the carrier (3) prevents canting between the Grate bars, especially the side grate bars (1) and the better guidance of the individual grate bars.
  • the device for grate firing in Incinerators in which the rust is usually through transversely to the direction of transport of the firing material itself extending, superimposed rows of grate bars is formed is such that thermal loaded fixed rows of grate over one on the Grate axis (4) slidably supported beam (3) with the wear plate (2) and the slide box (8) are connected, which, together with the transition angle (9), ensure the seal to the side wall (11).
  • the side grate bars (1) and The grate bars (5) are not attached.
  • the wear plate (2) follows the support row of grate bars (3) via the positive connection between Side grate bar (1) and driving plate (6) or the Driver (7).
  • the advantage of this arrangement is that no squeeze between grate bar row and Wear plate (2) arises because the side grate bar (1) remains at a defined distance from the wear plate.
  • the Arrangement of several side grate bars (1) on the Carrier (3) can serve to optimize the seal. Since the Row of grate bars lies unsecured on the support (3), can compensate for wear on the grate bar.
  • the Play between wear plate (2) and side grate bar (1) can be kept tight enough to prevent pinching Prevent solids and the seal too guarantee.
  • the construction according to the invention can be on one side be arranged a row of grate bars, but in particular also at both ends of a row of grate bars.
  • Figure 1 is a section parallel to one Row of grate bars with a view of the wear plates (2) shown, the grate bars (1 and 5) movable the carrier (3) rest, which in turn on the Grate axis (4) are arranged.
  • the section in Figure 2, perpendicular to Figure 1, shows the Side wall (11) leading to the grate by means of a sliding box (8) and transition angle (9) is sealed, and the Wear plate (2) with the one in the wear plate (2) retractable screw (10) on the slide box (8) is fixed.
  • the carrier (3) lies on the grate axis (4) on.
  • the side grate bar (1) and the grate bar (5) are on the carrier (3), the Driver device (7) in a recess in the grate bars (1) or (5) engages.
  • Figure 3 contains an exploded view of Figure 2 with the exception the side wall (11) and the grate axis (4), with (1) the Side grate bar, (2) the wear plate, (3) the support, (5) several grate bars, (6) the driver plate, (7) the Driver device, (8) the slide box, (9) the transition angle, (10) the screw for fastening the wear plate to the Slide box, (12) the connecting screws between the grate bars (5) and side grate bars (1).
