Definitions

  • the invention relates to a grate plate with the Features of the preamble of claim 1.
  • feed grates For burning solids are especially in Waste incineration plants with so-called feed grates in use, which take up the material to be burned and give it a feed motion.
  • the feed grates are formed by grate bars or plates, of some of which are stationary and others in groups back and forth in a feed direction or be moved against this.
  • the entire rust is usually covered by many grate bars arranged side by side and one behind the other or Plates formed. Through in the grate bars or plates - provided slotted nozzles flows in combustion air the combustion material lying on the grate.
  • the grate plates or rods heat up during the Operating due to the burning on the grate plates Solids considerably.
  • the through the slots flowing combustion air can, especially since it is mostly preheated is or for combustion reasons is subject to a quantity limitation, only a small one Effect cooling effect.
  • the temperature of uncooled grate plates or rods is therefore relatively high, resulting in a severe chemical corrosion and mechanical Wear of the grate plates. This is understandable undesirable.
  • grate plates For both reasons it is necessary to have grate plates to cool during operation or in a constant Keep temperature range.
  • a grate plate which covers the stretches the entire width of the grate.
  • the grate plate has many extending in parallel in the longitudinal direction Cooling channels on the ends to collect channels to lead.
  • EP 0621449 B1 is a grate plate with a meandering shape Cooling channel known. This leads across to the Grate plate and thus across to the feed direction the grate plate. Individual sections of the meandering Coolant channels are each in the longitudinal direction oriented.
  • This task is with a grate plate according to claim 1 with one on the thermal load of the Cooling plate oriented cooling system solved.
  • a coolant channel provided a central coolant connection has, while the connections at the state of Technology are usually arranged on the side.
  • the central Arrangement of the coolant connection becomes the coolant the grate plate and the coolant channel centrally or dissipated.
  • the coolant channel leads from here to peripheral grate plate areas where the coolant from or is supplied.
  • the grate plate By heating the coolant along the Coolant channel creates a heat gradient along the Coolant channel.
  • the grate plate is in operation from above heated up, there is a heat gradient of the central connection to the peripheral peripheral areas the grate plate, or vice versa. In any case, it is Heat distribution more or less symmetrical.
  • the grate plate can flow in the center of the coolant flow or be cooled more at the edge. In any case but is the temperature distribution with respect to a longitudinal median plane essentially symmetrical. So that will be Expansion behavior and thus also the thermal stress distribution the grate plate by cooling the center of gravity improved. There can be faults and thus the Formation of free cross sections between neighboring ones Grate bars or plates or jamming of moving Rust plates are avoided.
  • the grate plate is especially for feed grates intended. To do this, it has a lanyard at one end provided with which they with a grate plate carrier is connectable. This is, for example, a round bar or any other carrier. On their opposite At the end, the grate plate then has a storage means, for example in Form a foot on which it can be used on a suitable Abutment is slidably supported.
  • the abutment can, for example, a grate plate adjacent in the feed direction be.
  • the coolant connection in the middle between is arranged on both sides of the grate plate, it can if necessary, closer to the storage means or closer to that Lanyards may be arranged. In both cases becomes a more or less uniform heat gradient reached on both sides. It is therefore not essential required that the coolant connection be in the middle is arranged between the two ends of the grate plate. It is crucial that it is provided in one place, on an imaginary, in the middle between the flanks, lying and connecting the ends of the grate plate together Line lies.
  • the coolant connection is preferably something towards the front end of the grate plate offset so that the distance ratio to the ends is one in two. By such a central feed or The outflow of the coolant is thermal symmetry Maintained with sufficient accuracy and somewhat increased cooling in the front area.
  • a second coolant connection can be made to any one be arranged elsewhere on the grate plate. It can that from the central connector to the one spaced therefrom second coolant connection leading coolant channel designed as a single channel or on several subchannels be divided.
  • the coolant channel routing can vary be.
  • the channel can be formed by a cavity be that of several coolant connections on the periphery of the plate for removing coolant. Coolant is through the central coolant connection fed. It is also possible to use the coolant channel spiral (round) or square spiral. If necessary, the coolant channel can also be star-shaped be trained. Subchannels then extend radially away from the central coolant connection. This can be on the edge of the grate plate individually or in groups be led to further coolant connections.
  • the heat flow on the surface the grate plate by a suitable design of the Cross sections of the coolant channel can be achieved.
  • it can occur with a radial arrangement of the subchannels be expedient to the subchannels in the central area narrow the flow rate of the coolant increase here.
  • This creates a large central area the grate plate kept relatively cool, causing thermal expansion minimized.
  • the coolant channel is spiral-shaped there is a similar heat distribution. A a large part of the total length of the coolant channel is omitted on the edge area of the grate plate, whereas one correspondingly large area of the coolant channel divides several inner turns, the total one occupy a large area.
  • the grate plate according to the invention can in addition to the coolant duct connected to the central connection be provided with a further coolant channel, the example and preferably near the as a foot trained storage means is arranged.
  • This one more Coolant channel can serve, especially occurring here reduce large thermal loads. This is particularly advantageous if in this area Air gaps designed to supply combustion air are. Due to the incoming combustion air high thermal loads here. By the inflowing Fresh air and the associated combustion there is a corrosive attack on the metal of the hot Rust plate that is tempered by cooling.
  • the grate plate can consist of one or more parts be trained.
  • the execution of the grate plate as one-piece cast body allows a particularly inexpensive Manufacturing. It turned out to be special expediently exposed the coolant channel through Einund Pouring around corresponding pipes during manufacture the grate plate in the casting process. In order to can be relatively complex cooling channel geometries inexpensive can be produced without mold cores.

  • On hers opposite end 12 is the grate plate 3 with a Riot foot 14 provided a storage means for the Grate plate 3 forms. With the foot 14 is the Grate plate 3, as shown in Figure 1, on the next one Grate plate 3a of grate plate group 6.
  • Die Grate plate 3a thus forms an abutment for the grate plate 3.
  • the grate plate 3a which like all grate plates with the grate plate 3 described as representative corresponds, is with its transverse recess 9 on a rod 15 stored, which is parallel to the rod 11 across the entire width of the feed grate 1 extends.
  • Additional rods 16 are along the entire length of the Feed grate 1 distributed, arranged transversely. Every second The rod is fixed in place. Arranged in between Rods are connected to a drive device, that of the rod in question reciprocates oscillating movement in the direction of the furnace longitudinal direction 4 To give. This movement is in Figure 1 for the grate plate group 3 illustrated by arrows 17, 18. This results in an overall stair-shaped moving grate 1, the grate plate groups 5, 6, 7 in the manner of a Stairs are arranged one above the other, each second grate plate group (6) swings back and forth to the combustion material a feed movement in the longitudinal direction of the furnace 4 to issue.

E.g. it is possible to use the inlet Coolant connection 32 or 36 or on these subsequent turns a little further from the top 22 to be installed away. Then the turns are not on a common level, for example on the coat of a flat cone.
