Definitions

  • the invention relates to a combustion system for burning combustible material, in particular garbage, with a burner grate arranged in a combustion chamber and formed from rows of grate bars, which is preceded by a charging device arranged at a material inlet, with which the fuel is dosed to the burner grate, the burner grate receives the combustion air required for the combustion of the fuel lying on the firing grate, referred to as primary air, from the underwind area of the firing chamber, and a method for operating this combustion system.
  • waste When burning fuel, such as waste, there are various additional problems over burning a single fuel.
  • general waste was created to label waste, which is understood to mean processed household waste and similar fuel. These wastes are separated from scrap, glass, inert and compostable components and have a relatively high calorific value of approx. 15,000 kJ / kg. Because of the relatively high calorific value, this uniform waste places very high demands on the thermal treatment, ie on the control of the combustion processes on the mechanical furnace grate systems, not least because of the large differences in the composition of this waste, known as BRAM, RDF or FLUFF. However, these terms also include other fuel materials, for example bark waste or other materials that differ greatly from the normal heterogeneous waste composition and are composed of only a few components.
  • the high calorific value of the standard waste which is also extremely easy to ignite, requires a firing grate, the operation of which can be optimally adapted to the rapidly changing combustion processes.
  • Such a grate is known, for example, from US-A-4,320,710 by the same applicant.
  • This has a furnace with a horizontal or slightly inclined grate track and - seen in the flow direction of the fuel - rows of grate bars arranged one after the other, which are alternately arranged in a fixed position or moved back and forth.
  • the moving grate bar rows are moved back and forth by motorized lifting drives, by means of which they execute a swiveling movement around a torsion shaft and thereby move the grate bar rows.
  • adjacent, moving rows of grate bars perform an opposite movement, which are arranged alternately with the fixed rows of grate bars, not only pushing the fuel forward, but also continuously stoking and circulating it.
  • the drive of the grate bar rows is infinitely variable and enables a slow, continuous movement.
  • the horizontal or slightly inclined grate track results in a low overall height and has no parts to be serviced in the underwind area.
  • the necessary primary combustion air is supplied from below through grate diarrhea funnels, which act as air zones along the grate. Thanks to the high density of the rust covering there is a relatively high air pressure gradient between the grate underside and the garbage bed, with which an extraordinarily regular air distribution over the entire grate width is achieved regardless of the burning layer density and thus a local burning of the garbage layer with the disadvantageous consequences for the quality of combustion is prevented.
  • This object is achieved according to the invention in that when the grate is subdivided into grate zones, at least part of its grate bar rows without air outlet for the primary air into the combustion chamber are formed in the inlet grate zone adjoining the charging device. This ensures that despite the extreme ignitability of the standard waste, there is not already an intense fire at the transition from the loading device to the grate, which fulfills a prerequisite for high combustion efficiency.
  • the invention also encompasses a method with which an optimal combustion of the fuel material is made possible, and this is characterized in that at least the grate bar rows on the inlet side, which are made without air outlet into the combustion chamber, are brought in from the underwind area of the combustion chamber Primary air must be cooled.
  • the primary air heated by cooling the inlet-side grate bar rows can expediently be supplied to grate zones in which the grate bar rows are provided with air outlet into the combustion chamber.
  • the invention is based on the consideration that an optimization of the known incineration plant can be achieved if it is possible to evenly distribute the intensive fire which arises prematurely at the transition from the loading to the rust due to the ignitability of the standard waste over the rust zones.
  • the two embodiments shown in FIGS. 1 and 2 show such a solution.
  • the combustion system shown in FIG. 1 has a combustion chamber 1 which is provided with an essentially horizontal grate 2.
  • the secondary air required for the combustion of the flue gases is injected into the combustion chamber 1, see arrow 14.
  • the furnace grate 2 forms a grate track on which the material 3 to be burned, for example uniform waste, is heaped up and is moved over the grate to a discharge shaft, not shown.
  • the fuel 3 is introduced through a loading shaft 4 and is fed through a loading opening 6 in metered quantities via a crash 7 onto the firing grate 2 through a loading device 5 arranged at the base thereof.
  • the firing grate 2 is composed in the flow direction 8 from successively arranged grate bar rows, of which alternately the one grate bar rows moving bar rows 10 'and the other grate bar rows are fixed bar rows 10.
  • the firing grate 2 and the loading device 5 are supported on a substructure 11, which is not designated in any more detail.
  • the furnace grate 2 is divided into grate zones 12, the order of which is identified by Roman numerals.
  • the grate zones 12 correspond to underwind zones 13 arranged under the grate 2, through which primary air for the combustion of the fuel 3 lying on the grate 2 is fed separately to the individual grate zones I, II,.
  • the grate zones can be dosed individually with primary air.
  • the underwind zone 13 adjacent to the loading device 5 is designed in a special way.
  • the entry of the primary air indicated by arrows 15 takes place in the grate zones II, III, ... directly into the underwind zones 13 and this, represented by small arrows 16 on the top of the furnace grate 2, passes through the grate bar rows 10 into the overlying layer of fuel 3rd
  • the zone air supplied there which is mainly used only for grate bar cooling, can be used in the subsequent grate zones, as a result of which a uniform burn-off is achieved over the entire surface of the grate 2 becomes.
  • a targeted supply of the combustion air can be achieved according to the combustion process over the grate length.
  • the forward movement of the fuel and its fueling can be achieved by variable and different lifting speeds of the movement of the grate bar rows in the individual grate zones.
  • the grate zone I immediately following the loading device 5 is equipped not only with rows of grate bars without air outlet but also with those with air outlet 16.
  • the primary air 15 is guided as in the system of FIG. 1 through the baffles 17, which on the Underside of the grate bar rows without air outlet and then flows through the grate bar rows 10 with air outlet 16 into the layer of fuel 3 lying on the grate 2.
  • the cooling air heated on the grate bar rows without air outlet is not discharged into other grate zones; the heated cooling air passes through the grate bar rows with air outlet 16 of the first grate zone I into the fuel layer.
  • the fuel can be burned down evenly.
  • the even burn-off avoids temperature peaks in the fire bed and prevents the formation of carbonization gases.
  • Existing incineration plants can thus with relatively little effort for the combustion of high-calorific waste or standard waste such as BRAM, RDF and FLUFF or the like. and other high calorific fuels.
  • the grate bar rows 10 without air outlet are of a similar shape to the grate bars with air outlet. It is thus possible to replace grate bars with air outlet by grate bars 20 without air outlet without changing dimensions.
  • the grate bars 20 essentially consist of a grate bar surface 21 on the underside of which two cooling fins 22 are arranged at a distance.
  • the cooling fins 22 have two bores 23 for receiving coupling rods 24, with the aid of which see Fig. 3, a number of grate bars 20 is held together.
  • the furnace grate 2 is delimited by grate side plates 30, to which brackets 25 are fastened on the downwind side, on the edge 26 of which a cooling fin 22 of the outermost grate bar 20 is hooked in the fixed bar rows 10. In this way, the play between the outermost grate bar and the grate side plate 30 is kept small.
  • the primary air rising through the guide plates 17 is indicated in FIG. 3 by arrows 15. It can be seen from FIG. 4 that the grate bar surface 21 has a curvature 27 on the combustion chamber side which merges into a support shoe 28.
  • a mounting bracket 29 is provided for receiving by a bar holder (not shown). With the reciprocating grate bar rows, this grate bar holder is moved back and forth for the movement of the grate bars, as is described in the patent mentioned at the beginning.
