Definitions

  • the invention relates to a water-cooled thrust combustion grate for waste incineration plants which is particularly suitable for burning rubbish and waste with high Calorific values.
  • thrust combustion grates have stationary and movable ones Grate levels from grate plates or from a series of grate bars, the grate plates lie on top of each other in a staircase.
  • This combustion feed grate can be installed in this way be that the burning bed is substantially horizontal, or inclined, wherein Inclinations up to 20 degrees or more are common.
  • rust plates these are preferably made of sheet steel and form board-shaped hollow bodies which are extend across the width of the entire grate track and through which water as a cooling medium is directed.
  • Every second grate plate is movable and can therefore be a stoking or transport stroke To run. If it is a feed grate, the movable Push the grate plates with their front side of the firing material onto the next lower grate plate.
  • a moving-back grate forms a somewhat incorrectly installed, inclined stairs.
  • the end faces of the movable grate plates transport one Sliding grate back the firing material lying behind them, after which this in again Rolls down in the direction of the tendency to rust.
  • the movable grate plates, that is arranged between two stationary grate plates are usually collective moved back and forth in the direction of their slope. This ensures that the burning rubbish lying on the grate with a long dwell time of 45 to 120 minutes constantly relocated and evenly distributed on the grate.
  • a water-cooled thrust combustion grate has become known from EP-0'621'449.
  • This grate has grate plates that extend over the entire width of the grate track and therefore do not consist of several grate bars per grate level.
  • the movable grate plates like the stationary ones, they are hung on the rear on cross tubes, which are located in the Collective move operation forwards and backwards and thus move the movable grate plates.
  • a disadvantage of this method of driving the movable grate plates is that that a small particle that is in operation laterally between the grate plate and the side End plate jammed, can cause the grate plate to tilt sideways, this means that the plate is no longer exactly parallel to the neighboring one when viewed from above stationary grate plates.
  • a moving grate module has become known in which an individual Drive of the movable grate plates is disclosed.
  • the moving ones roll here Rust plates on steel rollers, but are only on the side by means of sliding friction on the end planks guided.
  • the drive is realized with a hydraulic piston-cylinder unit, which acts on the grate plate approximately in its center. Even with this construction canting is inevitable. A small particle settles between the grate plate and a lateral end plank, this creates very large frictional forces, firstly require large hydraulic cylinders to overcome, and secondly, a correspondingly large amount of wear.
  • the object of the present invention is therefore to provide a water-cooled thrust combustion grate to create, in which the movable grate steps with less wear and thus long service life can be moved individually, so that the combustion process can be specifically optimized, and which also has minimal slag diarrhea.
  • the sliding combustion grate should be easy to assemble and easy to maintain, by being in a special version from below during the combustion operation is accessible and from there the individual drives of the grate plates can be replaced individually are.
  • a water-cooled thrust combustion grate for burning from rubbish which is made of stairs, with its front lower edge on top of each other there are resting, alternately stationary and movable hollow grate plates, each of which stretches across the entire width of the Rohstbahn, or several assembled side by side extend across the entire width of the grate track, the movable grate plates by means of a hydraulic cylinder-piston unit are driven, and which is characterized in that it is laterally from water-cooled planks Hollow profiles is limited, each consisting of at least two tight in the longitudinal direction flanged sections exist, these planks over several vertically horizontally arranged spacer tubes running towards them are firmly screwed together are that between the planks two more, flanged together in the same way Hollow profiles for the supply of purge air and cooling water run on individual spacer tubes are attached, and that the stationary grate plates on the back of a spacer tube rest while the movable grate plates on the back of at least one steel roller
  • FIG. 1 The basic structure of this sliding combustion grate with its essential elements can be seen most easily from FIG. 1.
  • FIG. 1 is a longitudinal section of one Rostes shown in a perspective view as it presents itself during construction, where individual grate plates are still missing and thus the view of the substructure is clear is.
  • This is a grate inclined downwards in the conveying direction.
  • Two vertical, parallel to each other side steel walls 1,2 are with a Number of spacer tubes 3.4 stably connected to each other. These spacer tubes 3, 4 run across the grate and extend across the light on two different levels Width between the two side steel walls 1,2.
  • the two steel walls 1,2 left and right of the grate can consist of several steel plates or parts, which in are suitably screwed together.
  • the spacer tubes 3.4 pass through them Steel walls have a thread on both sides and are by means of cones sitting on them and nuts 7 firmly screwed to the side steel walls 1, 2.
  • the spacer or cross tubes 3 of the upper level also serve as support tubes for those lying on them stationary grate plates 5.

  • Two run along the upper edge of the steel walls 1, 2 Hollow profiles in the form of square tubes, slightly offset from each other 8,9, which are closed at their lower end by being welded there.
  • These square tubes 8.9 form the side planks of the grate run and limit in operation the firing bed laterally. They are water-cooled and are going from bottom to top forcibly flowed through by water, so that its interior is always completely filled with water is filled out.
  • the individual grate plates 5,6 are made of sheet steel and also as Hollow body designed, which are forced to flow through water so that you The cavity is always completely filled with water and there are no air bubbles inside can.
  • All steel sheet parts of the grate be it the side planks 8.9 or the Grate plates 5,6, which come into contact with the firing material, are thus on the rear Sheet side constantly covered by water. So everyone can be in contact with the fire parts are constantly cooled and kept at a stable temperature so that practically no dilations occur. As a result, it is not necessary to the side of the grate plates to provide any compensating elements.
  • the grate is thereby in its construction very much simplified.
  • the stability of the grate construction is essentially due to the spacer or transverse tubes 3.4 achieved the two in two parallel planes to each other Brace and brace the outer steel walls 1, 2, as has already been described.
  • the square tubes or hollow profiles 10, 11 point to this Purpose welded cross tubes with such an inner diameter that the retaining bolts Fit 13, 14 in the support elements 12.

  • the clear expanse of the The guide groove is selected so that it is slightly larger than the diameter of the horizontal one Steel roller 15 is, whereby the grate plate from the roller 15 in the transverse direction to the grate track is adequately managed.
  • To guide the front of the movable grate plate are on 8 additional steel rolls 20, 21 are attached to the planks.
  • the associated movable Rust plate now has such recesses laterally on its front underside that a guide surface is formed on each side, which is parallel to the side surface of the Grate plate runs, but is set back relative to this, and on which this Unroll steel rollers 20, 21 when moving back and forth.
  • Each movable grate plate thus shows to a certain extent a three-point bearing.
  • the grate plate is horizontal and vertical from the corresponding steel rollers 15, 16, 17 and at the front it is guided on the left and right by the steel rollers 20, 21 while with its front lower edge on the next lower stationary
  • the grate plate rests and slides on it when it is moved back and forth.
  • Your front lower edge is specially provided with a sliding shoe made of wear material, which from time to time Time can be changed without the actual grate plate being replaced got to.
  • An advantage of the construction described here is that the movable Grate plates are guided precisely and there is no more friction on the side because the side Guide is set so that between the side edge of the movable grate plate 6 and the adjacent plank 8 a constant short distance is maintained so that no jamming small parts can fall into this slot and at the same time the slot but it is so far that sliding friction does not occur.
  • the grate plate can because of this precise guidance also no longer tilt as with conventional ones Constructions was still possible. If there has been any canting so far, the plate simply toggle against the greatly increased sliding friction with great force until that the cantilever-causing clamping part fell down or out of the slot between The grate and plank worked out.
  • Grate plates fire the fire or the firing material on the grate with larger strokes be transported.
  • the constructive solution with the support elements 12 between the longitudinal square tubes 10, 11 even allow the replacement of a drive unit during the operation of the grate.
  • the grate plates 5.6 either extend individually over the entire width of the grate track or in a variant several grate plates are connected to each other so that they are without Slits between them cover the entire width of the grate and therefore hardly any grate diarrhea occurs, which fall down on the fitters who are under the grate could.
  • each support element 12 is connected to the square tubes 10, 11 by means of the bolts 13, 14 suspended so that by knocking out the rear bolt 13 the whole support element can be tilted back, after which the articulation of the hydraulic cylinder 18 is accessible and this can be easily expanded.
