Definitions

  • the invention relates to a water-cooled shear combustion grate for waste incineration plants, which is particularly suitable for the combustion of inhomogeneous refuse and waste with partially high calorific values.
  • shear combustion grates have stationary and movable grate stages of grate plates or of a series of grate bars, wherein the grate plates rest on each other in a staircase shape.
  • the grates may be installed so that the fuel bed is substantially horizontal, or inclined, with inclinations of up to 20 degrees or more being common.
  • grate plates these are preferably made of sheet steel and form board-shaped hollow body, which extend over the width of the entire grate and through which water is passed as the cooling medium.
  • every second grate plate is designed to be movable and can thus carry out a picking or transporting stroke. If it is a feed grate, then the movable grate plates can advance with their front side firing material to the next lower grate plate. In contrast, a repulsion grid forms a somewhat wrong built, inclined stairs with overlapping steps.
  • the front sides of the movable grate plates transport at a backward grate the firing material lying behind them, after which it collapses again in the direction of rust tendency down.
  • the movable grate plates that is, each arranged between two stationary grate plates grate plates are in the direction of their inclination back and forth emotional. This ensures that the burning waste lying on the grate is constantly relocated with a high residence time of 45 to 120 minutes and distributed evenly on the grate.
  • the previous water-cooled shearburning grates are used in widths of about 3m to 6m, which means a shearburning grate is then composed of grate plates, which extend over this width and are therefore 3 to 6 meters long.
  • a Schubverbrennungsrost with laterally limiting planks is referred to as rust.
  • the drive for each movable grate plate by means of a below the grate and behind the relevant movable grate plate centrally arranged, single hydraulic cylinder-piston unit, as in EP 0 874 195 described and shown in detail.
  • the grate plates are guided laterally by means of horizontal steel rollers on the side planks which laterally limit such a combustion grate.
  • the drive with a central cylinder-piston unit pushes at even longer grate plates or even larger grate widths to its limits, despite laterally rolling guide or side storage of the grate plates by means of steel rollers on the side grate planks.
  • the grate plates threaten but namely to tilt a width of more than 6 meters.
  • the conventional drive solutions for the movable grate plates are also located below the grate in the middle of the grate plates and are accessible there only when the grate is not in operation.
  • EP 0 757 206 A2 has become known rust for combustion plants, which consists of water-cooled, staircase-shaped successive grate plates.
  • the grate plates which can be displaced in the longitudinal direction of the grate can be moved back and forth relative to the stationary grate plate carriers by means of double-acting hydraulic or pneumatic cylinders arranged on both sides (column 4, lines 43 to 47).
  • the DE 28 06 356 A1 shows a drive for feed grates and mentions on both sides of the movable grate arranged hydraulic cylinders which initiate the forces for moving the grate frame on both sides (page 3, first section). And it is also pointed out that on both sides of the grate frame a synchronization of the movement of the hydraulic piston is provided.
  • a problem to be solved together with the synchronization of the thrust forces acting on both sides of the movable grate plates is the collection of the load, which is considerable in the case of overlong grate plates, and optionally the separation of the primary air which is necessary over the grate width.
  • the object of the present invention is therefore to provide a water-cooled shear combustion grate, which is developed from the prior art so that it allows the realization of much wider grate webs, that is, grate webs of 6 meters wide and more.
  • grate webs of 6 meters wide and more.
  • a possible tilting of the movable grate plates should be effectively avoided even with grate plate lengths of more than 6 meters.
  • the drive should be easier to maintain by being accessible in a special design during combustion operation and the hydraulic piston-cylinder units of the individual drives the grate plates are individually replaceable without having to interrupt the operation of the grate.
  • the primary air supply of such a combustion grate with over-wide grate web should also be separable over the width thereof.
  • FIG. 1 The basic structure of a conventional shear combustion grate with its essential elements is made FIG. 1 It can be seen how it presents itself during assembly, ie where individual grate plates are still missing and thus the view of the substructure is released.
  • This is a downwardly inclined grate with a grate width of about 2m.
  • Two perpendicular, parallel to each other lateral steel walls 1.2 are connected to a number of spacer tubes 3,4 stable together. These spacer tubes 3,4 extend transversely to the grate and extend on two different levels over the clear width between the two lateral 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 are screwed together in a suitable manner.
  • the spacer tubes 3,4 enforce these steel walls 1,2, have on both sides of a thread and are screwed by sitting on it cones and nuts fixed to the side steel walls 1.2.
  • the spacer or transverse tubes 3 of the upper level serve as support tubes for the stationary grate plates 5 resting on them at the same time.
  • the lowermost stationary grate plate 5 rests with its front edge on a ejection lip 7 welded in firmly between the lateral steel walls 1, 2. and with its rear portion it is hung over the first upper spacer or cross tube 3.
  • a movable grate plate 6, which rests with its front lower edge on the first, lying below her stationary grate plate 5.
  • the front lower edge of the next higher, stationary grate plate 5 rests on itself, and so on.
  • the individual grate plates 5, 6 are penetrated at their beveled front side by primary air slots 8 through which primary air for combustion is blown into the kiln from below.
  • primary air slots 8 through which primary air for combustion is blown into the kiln from below.
  • the individual grate plates 5, 6 are penetrated at their beveled front side by primary air slots 8 through which primary air for combustion is blown into the kiln from below.

  • the grate plates consist of a carrier flu, in which a flow-through hollow body is inserted as a heat sink, which is then covered by a Verschleissplatte which is clamped to the support frame and the heat sink to ensure good heat transfer.
  • All steel sheet parts of the grate be it the lateral square tubes 8,9 or the grate plates 5,6, which come into contact with the kiln, are thus constantly covered by water on the inner side of the sheet, or at least cooled by a water-cooled heat sink.
  • all parts in contact with the fire can be constantly cooled and kept at a stable temperature, so that virtually no dilatations occur. As a result, it is not necessary to provide any compensation elements on the side of the grate plates.
  • the stability of the grate construction is achieved essentially by the spacer or cross tubes 3, 4, which brace and brace the two outer steel walls 1, 2 in two parallel planes relative to each other, as has already been described.
  • transverse tubes 3,4 extend along the grate on both sides of its longitudinal center two hollow sections in the form of square tubes 11,12, which are connected at the bottom and top in some places with transverse transverse tubes 3,4.
  • One of the square tubes, namely the square tube 11 leads from bottom to top the cooling water for the grate plates 5, 6, while the other square tube 12 supplies scavenging air and cooling air for the hydraulic components of the drives of the movable grate plates 6.
  • support elements 13 are installed for the movable grate plates 6.
  • these support elements 13 are held by means of two bolts, which pass through the two square tubes 11, 12.
  • the square tubes or hollow sections 11, 12 have, for this purpose, welded transverse tubes with an inner diameter such that the retaining bolts for the supporting elements 13 fit into them.
  • the support elements 13 themselves each have a steel roller 16 lying parallel to the corresponding grate plate plane, as well as a steel roller 17, 18 running there in the vertical plane to the left and right. On the latter rolls the movable grate plate 6, and the horizontal steel roller 16 serves for lateral guidance on the rear side of the grate plate 6. Between the support member 13 and the front lying movable plate so far a hydraulic cylinder-piston unit 21 with piston 22 is installed. On the planks, that is to say on the square tubes 9, 10, two horizontal steel rollers 19, 20 are mounted for each movable grate plate, at which they are guided laterally on the outside.
  • FIG. 2 shows an area of this conventional grate FIG. 1 seen with this conventional drive of the movable grate plates 6 in a longitudinal section from the side.
  • the grate plate 6 rolls on the rollers 17 of the support element 13, which are fastened by means of the two bolts 14,15 to the Vierkantohren 11,12.
  • Each of these support elements 13 can be tilted by knocking out the rear bolt 14 to the rear, after which the articulation of the hydraulic cylinder 21 is accessible and this can be easily removed. However, this can only after decommissioning of the Rust done.
  • Behind the grate plates 5,6 can be seen the square tube 10, which forms the side plank, and below the side wall 2 with the cross tubes. 4
  • FIG. 1 and 2 shown the hydraulic drive arranged directly under the grate plates each in their middle.
  • a parallel drive of the movable grate plates is realized on the here presented shear combustion grate, which then allows the realization of much wider grate paths, and a lateral guidance of the grate plates with their own steel rollers is unnecessary.
  • Each movable grate plate is individually driven for this purpose at its two side ends or at their lateral end portions, these two individual drives for each movable grate plate are perfectly synchronized with each other.
  • FIG. 3 a single drive unit is shown on the one side of a movable grate plate 6 in a schematic diagram.
  • a connecting rod 30 acts on the movable grate plate 6.
  • This connecting rod 30 is articulated to a crank 31 which sits on a crankshaft 32.
  • the crank 31 here has a slot 38 in which the pin 39 of the connecting rod 30 stores, because the connecting rod 30 as shown with a double arrow linearly in its direction to move back and forth, while the crank 31 by a few degrees back and forth pivots and thus their end does not perform a linear movement.
  • the crankshaft 32 is mounted in a sleeve 33, which passes through the side wall of the grate construction and is welded or screwed stable in this, namely at the point shown by an arrow.
  • the crankshaft 32 On the outside of the grate construction, the crankshaft 32 is equipped with a further crank 34, which is articulated to the end of a piston rod 35 of a hydraulic cylinder 36.
  • cranks 31,34 are simply plugged over the crankshaft ends and each secured with a lock nut.
  • the hydraulic cylinder 36 is connected at its other end pivotally connected to a holder which is anchored on the outside of the side wall of the grate construction.
  • the axis of the sleeve 33 extends at a right angle to the direction of movement of the movable grate plate 6, and the crank 31 for the connecting rod 30 on the crankshaft 32 can be pivoted about 120 ° to 180 ° to the crank 34 at the other end of the crankshaft 32 be.
  • crank 34 is actuated at this other end of the crankshaft 32 and the crankshaft 32 is rotated accordingly, which is done by forward and backward movement of the piston 35 by means of the hydraulic cylinder-piston unit 35,36, then the visible end of the movable Grate plate 6 moved forward and backward.
  • the crankshaft 32 can be rotated by 0 ° to about 60 ° by targeted control of the hydraulic piston-cylinder unit 35,36, so that the thrust of the movable plate 6 is continuously variable.
  • On the other side of the grate track an identical drive is arranged for this movable grate plate 6, so that therefore a parallel drive is formed.
  • Proportional valves in combination with a displacement measuring system for the hydraulic piston-cylinder units used make it possible for these to move in and out exactly synchronously, so that the movable grate plate 6 driven thereby always runs exactly parallel to the stationary grate plates 5.
  • the hydraulic components are completely installed outside the grate construction with this drive construction. Thus, only the coarse mechanical parts of the abrasive effect of the underwind are exposed to the entire drive structure, which can not harm them. The more sensitive drive parts are outside the grate and there always accessible, even during operation of the grate.
  • Each individual movable grate stage is individually drivable in this way via two separate hydraulic cylinder-piston units, which are mounted on the two outer sides of the grate construction on the side walls opposite all other movable grate plates. All other movable grate plates are driven in the same way by two hydraulic drives.

  • Both end sides of the movable grate plates 6 are equipped with such hydraulic drives, so that therefore each movable grate plate 6 has an individual parallel drive. This drive mode makes it possible to realize much wider grate tracks than previously known.
  • Two to four or more conventional grate webs can be replaced with a single, single-track grate. Because the water-cooled grate plates can be kept on a narrow temperature band thanks to their cooling, there is no dilatation problem. The bending stiffness of the grate plates in the direction of movement is extremely high because of the flat design of the grate plates 6 and is no obstacle to the operation of grate plates of far more than 6 meters in length.

  • the grate steps are therefore sufficiently stiff in the drive direction, which means there are no additional auxiliary structures such as grate carriages, transverse shafts or the like needed. Only the weight of the grate and the overlying refuse is absorbed by the longitudinal members 45. Such a grate width can not be realized with the conventional grate bars made of cast iron due to the smaller width of the grate bars, or with such Elements would need an auxiliary construction. In the example shown, three steel girders 45 are installed, so that at a grate width of 12 meters, the grate plates 5,6 are supported every 3 meters.
  • the stationary grate plates 5 rest directly on these steel beams 45, while the movable grate plates 6 are equipped on its underside with steel rollers, and then roll these steel rollers on top of these steel beams 45, whereby the load due to the burning material as well as the weight of the water-cooled grate plates , 6 is supported by these steel beams 45.

In addition, this compartment can also be subdivided into different longitudinal compartments via the length of the grate rail by incorporating corresponding partition walls 49. This has created a whole array of primary air compartments, with each compartment equipped with a separate primary air supply. Accordingly, the fire can be driven individually according to the air requirement at any point above a primary air compartment with its own primary air pressure.
