Definitions
- the present invention relates to a method for burning waste on a combustion grate. Furthermore, the invention relates to a combustion grate for carrying out the method and, moreover, to a single grate plate which, in a plurality, permits the production of a corresponding combustion grate.
- Burning grates have always been known for the combustion of rubbish.
- a special type of combustion grate is the so-called thrust combustion grate, which includes moving parts which are suitable for performing strokes, whereby the fired material is conveyed on the grate becomes.
- the feed grids are differentiated from the feed back grids.
- the firing material is conveyed in the forward direction to the firing material loading, on the latter in the backward direction.
- the return grids and feed grids inclined downwards in the forward direction have been known for decades and have found widespread use in waste incineration plants.
- the present invention relates in general to combustion push grates, regardless of whether these convey the firing material forwards or backwards to the loading direction, the feed grate will be dealt with first.
- a mechanical drive device ensures that each such second grate step executes a stoking stroke, which consists in that these grate steps back and forth in the direction of their inclination are movable here. This ensures that the burning waste lying on the moving grate is constantly relocated with a long dwell time of 45 to 120 minutes and evenly distributed on the grate.
- the feed grate is fed with rubbish at the top of the grate. In this so-called loading area, the incoming rubbish is initially dried by the thermal radiation acting on it. This is followed by an area on the feed grate in which gasification begins, in which the solid components of the refuse change into the gaseous state and release energy.
- the moving grate can be compared to a tiled roof with the opposite slope. It has the advantage that the embers are pushed back to the beginning of the grate.
- the primary combustion overlaps from the beginning of the grate to the end.
- This intensive rubbish fire which begins directly at the beginning of the grate, is an essential feature of a push-back grate. It is created by combining and mixing already burning refuse components with the upward conveying effect of the grate with not yet ignited parts of the firing material, whereby a zone of very high temperature with high combustion intensity is already created at the beginning of the grate.
- the stoking movement consists on the one hand of the natural downward movement of the firing material due to gravity and the counteracting pushing movement of the grate.
- a buffer effect against fluctuations in the calorific value of the fired material can be achieved generate by reliably preventing the ignition from tearing off or the fire running away towards the end of the grate.
- Such push-back grates ensure a uniformly high burning layer without holes that would leave the grate uncovered and thus lead to its thermal wear.
- the individual grate bars are made of cast chrome steel regardless of the grate type, which is intended to ensure high wear resistance and heat resistance.
- the grate bars are machine-ground to achieve a tight fit and thus a high flow resistance of the grate covering for the primary air flowing in from below, with the least possible amount of grate diarrhea.
- the primary air enters the combustion bed via a gap, also ground out of the side surface, in the area of the head end of the grate bar.
- the head end is covered by the next overlapping grate bar, which should keep these air gaps clear.
- a combustion air supply that is defined at any time and at any location on the grate is the most important prerequisite for operating a waste incineration plant that should have the lowest possible emissions.
- the primary air in the grate longitudinal direction Burning bed supplied via 5 to 6 separate air zones.
- the supply of combustion air to each such individual air zone is measured and regulated separately. This is done either via supply pipes with Venturi measuring points or pressure measurements via the individual orifices that are assigned to each primary air zone.
- a push-back grate has compensating segments. These usually consist of movable center piece plates and movable side plates of the grate, which are able to compensate for this dilatation.
- the object of the present invention is now to provide a method which allows a more optimal combustion of the waste on a combustion grate by the primary air supply can be controlled so that an optimal combustion chamber temperature spectrum is achieved and thus the calorific value of the waste to be burned better is exploited.
- This object is achieved by a method for burning garbage on a combustion grate, characterized in that the combustion grate is tempered by a medium flowing through it.
- a grate plate for producing a combustion grate for burning rubbish which is characterized in that it generally has the shape of a board on the outside and that its length is intended to cover the entire width of the combustion grate to be produced or to extend across the entire width of a grate track to be created and thus a full grate level to form that this grate plate is made of sheet metal, is hollow on the inside and has a connection piece on one side and a discharge piece on the other side for the supply and discharge of a medium to be flowed through.
- a combustion grate for burning rubbish which is characterized in that it consists of a plurality of grate plates according to one of the claims 5 to 8, in that these grate plates with an inclined broad side in their longitudinal direction over the entire width of the Combustion grate or a grate track and each form a full grate level, the one grate plate overlapping the adjacent grate plate and resting on it.
- a single grate plate 1 of such a combustion grate is shown in perspective in FIG.
- the example of the design of the grate plate 1 consists of two chrome steel sheet shells, namely a shell for the grate plate top 2 and a shell for the grate plate bottom 3.
- the two Sheet metal shells 2, 3 are welded together.
- their edges are advantageously shaped in such a way that the two shells 2, 3 can be slipped into one another with their edges.
- the two end faces of the hollow profile thus created are welded tightly with end plates.
- the rear end plate 4 is inserted, while the front end face 5 is still free and allows an insight into the interior of the hollow profile. After both end faces have been closed, a cavity sealed to the outside is formed in the interior of the grate plate 1.
- This medium is basically used for tempering the grate plate 1 and must fundamentally be a flowable medium, ie a gas or a liquid. It is therefore possible to let a cooling liquid flow through the grate plate 1, for example.
- the cooling liquid can be, for example, water or oil or another liquid suitable for cooling.
- a liquid or a gas can also be used to heat the grate plate 1.
- it can be used for cooling as well as for heating, that is to say in general for tempering the grate plate 1.
- Bottom 3 opposite Openings 8, 9 are tightly connected to one another with tubular elements 21, for example conical tubes 21 with a round, elliptical or slot-shaped diameter, each of these elements 21 being welded tightly into the grate plate top 2 and the grate plate bottom 3.
- the funnel-shaped bushings thus created through the grate plate 1 enable targeted ventilation of the firing material lying on the grate by air flow from the bottom side of the grate plate 3.
- supply pipes or hoses for the primary air to be blown are connected to the individual mouths of the continuous pipes on the underside 3 of the grate plate 1.
- the grate plate 1 shown here has a cross section such that a largely flat surface 2 is formed on the top 2 of the plate 1, on which the firing material is intended to lie.
- the lower side 3 has bevels, so that feet 10, 11 are formed to a certain extent.
- a round rod 13, on which the grate plate 1 rests, runs in the interior of this channel 12 along one foot 10, which here contains a channel 12.
- the other foot 11 is flat at the bottom and is intended to rest on the adjacent grate plate, which is of the same shape.
- such a grate plate can also consist of a prefabricated hollow profile, in which only the two end sides are welded together with a suitable end plate.
- the funnel-shaped continuous tubes can be welded in later by using the Small holes are milled out or drilled out on the upper side, and slightly larger holes on the underside of the grate plate opposite. From the side of the larger holes, funnel-shaped tubes or elements can then be pushed through the grate plate, which are then sealed to the outside of the grate plate.
- These tubes or elements 21 are therefore chosen to be conical or funnel-shaped, because in this way any possible sticking of rust in them can practically be ruled out by the walls being somewhat overhanging due to the conicity.
- the mouths can then be ground flat with the top of the grate plate. Connection pipes or hoses can be screwed to these continuous pipes at the bottom.
- a manganese-alloyed sheet of such a thickness is suitable that it can just be bent, that is to say of a thickness of the order of about 10 millimeters.
- the sheet should also have a sufficiently good thermal conductivity so that no large temperature differences can occur within the grate, thus avoiding stresses in its material.
- a grate plate is made from two half-shells or with hollow profiles, it is in any case significantly cheaper to produce than the step of a conventional grate, which consists of a large number of grate bars.
- a grate plate is shown partially cut open in FIG.
- This grate plate is divided into two chambers 51, 52 by means of a partition bulkhead 50.
- This grate plate is one that is installed in the first part of a combustion grate, in which no primary air supply is used, which is why the plate shown here, in contrast to that in FIG. 1, contains no tubular elements and thus also has no openings.
- Combustion grates usually consist of three to five different zones, each consisting of a number of several grate plates, primary air being supplied only from the second zone.
- Baffles 53 are installed in the interior of the two chambers 51, 52, which are welded tightly to the bottom of the grate plate, but on the top leave an air gap of a few tenths of a millimeter to the inside of the top of the grate plate, so that gas gaps can be exchanged within the baffles through these air gaps 53 formed labyrinths can take place.
- a cooling medium is pumped through the connection stub 6 into the grate plate chamber 52, which then flows through the labyrinth formed by the baffles 53 as indicated by the arrows and finally flows out of the chamber through the stub 7. Because the cooling medium has a larger area for heat absorption while flowing through, a better heat exchange is achieved.
- each plank 54 is arranged on both lateral edges of the grate plate, along which the movable grate plates slide back and forth.
- each plank 54 consists of two superimposed square tubes 55, 56, the intermediate wall 57 thus formed being shortened at one end, so that a connection is formed there between the inside of the two square tubes 55, 56.
- Coolant is pumped from a connection 58 through the plank 54, which then flows through the two square tubes 55, 56, as indicated by the arrows, and finally flows out of the plank 54 again through the connecting piece 59.
- a shielding plate (not shown here) can also be arranged, which surrounds the plank 54 on the side of the combustion plate and serves as a wear element because of the friction occurring between the grate plate and the plank.
- FIG. 3 shows a schematic cross section through a combustion grate which consists of a plurality of grate plates, as have just been described.
- Figure 3a) and Figure 3b) show two different snapshots of the operation of this combustion grate, the movable grate plates perform strokes.
- Those grate plates 14, 15 which are drawn with solid lines form stationary grate plates, while those grate plates 16, 17, which are drawn with a hatched cross-section represent movable grate plates.
- These movable grate plates 16, 17 can now perform strokes by moving back and forth as indicated by the arrows.
- the drive takes place via the round rods 13, which are fastened to profiles 18, which in turn can be moved back and forth via a mechanical drive.
- the combustion grate as shown in Figure 3 is horizontal with respect to the general direction of conveyance. This is a feed grate, because the firing material is conveyed by the grate or by the moving grate plates, every second of which is movable and carries out strokes.
- FIG. 4 Another embodiment is shown in FIG. 4.
- the combustion grate is constructed identically from several combustion grate plates, except that it is now inclined on one side by approximately 25 °. Therefore, the grate plates now push the firing material upwards against the general conveying direction by means of the strokes they have carried out. It is thereby achieved that the firing material, which moves slowly downwards on the grate due to gravity, is always pushed back a little by the shear strokes and thereby rearranged, which is conducive to complete combustion.
- a combustion grate made of such grate plates can be horizontal, downward or upward inclined, as required.
- FIG. 5 shows a supply siphon 30 as it can be installed below the combustion grate for each primary air supply line. Because some rust diarrhea can inevitably fall down through the small openings in the grate plates, this grate diarrhea falls into the supply lines for the primary air in the form of finely powdered slag. It is therefore necessary to provide such supply siphons 30 in which the grate diarrhea is collected and at the same time the unimpeded continuous air supply is ensured.
- Such a siphon is designed at the bottom, for example, similar to the shape of an Erlenmeyer flask, the bottom of the siphon being closed by a spring-loaded flap 31.
- the flap 31 is pivotable about a hinge 32 and a spring 33 loads the flap 31 with its one leg 34 from below and with the other leg 35 the side wall of the siphon.
- An actuating lever 36 which is fixedly connected to the flap 31, projects away from the hinge 32 and is in the effective range of a solenoid 37. When its coil 38 is energized, this electromagnet is able to attract the actuating lever 36 to its core 39, as a result of which the flap 31 is opened, and the accumulated grate diarrhea 40 falls into an underlying trough.
- the primary air supply line 41 leads into the interior of the siphon 30.
- This supply line leads downward into the siphon, so that rusting diarrhea can under no circumstances fall into this supply line, since a strong air stream does not necessarily have to flow through it continuously be.
- the neck 42 of the siphon is Connected via a heat-resistant flexible line 43 to the lower mouth of a single conical tube that leads through a grate plate 1.
- the method according to the invention can now be carried out with a combustion grate constructed from grate plates 1 of this type.
- Flowable media such as gases or liquids can be used as a medium for tempering the grate.
- the aim of the process is to keep the temperature of the grate at a constant level and thereby significantly reduce its wear.
- the temperatures should thus be in the range of up to approximately 150 °, which entails a low thermal material load and has a correspondingly positive effect on the mechanical strength and wear resistance of the grate plates 1.
- the medium used for temperature control can be in a heat exchange with the primary air to be supplied.
- a commercially available heat exchanger can be used for this, which works according to the counterflow principle.
- thermoelectric grate By means of such a heat exchanger it is possible, for example, to preheat the primary air, which is conducive to optimal combustion with certain combustibles. Especially with organic waste components, for example with rotten or rotten vegetables or fruits, preheating the primary air is very desirable because it improves combustion.
- preheating the primary air is very desirable because it improves combustion.
- the temperature control medium can absorb the heat from the exhaust air from the combustion that is already taking place and then introduce it into the grate plates of the combustion grate.
- a second, just as significant part of the method according to the invention is that the fired material is optimally supplied with primary air, so that its calorific value is used in the best possible way and its combustion takes place as completely as possible.
- the temperature spectrum in the combustion chamber above the combustion grate is determined using a large number of temperature measuring probes. These measuring probes can also be built into the surface of the grate plates.
- the temperature spectrum can also be determined using a pyrometer. The targeted metering of the primary air supply for each individual supply line, of which there are a large number in the combustion grate according to the invention, enables the current temperature spectrum in the combustion chamber to be approached approximately to the optimum spectrum.
- solenoid valves can be used in the supply lines, which are controlled by a central microprocessor in which the optimally selected combustion chamber temperature spectrum can be stored. By constantly measuring the real spectrum and comparing it with the ideal spectrum, a control loop can be formed, according to which the individual solenoid valves are individually opened in a slightly more or less precise manner and Allow primary air to flow through the individual supply lines.
- the primary air supply is provided by one or more powerful compressors or fans.
- the method according to the invention enables a greatly improved combustion and thus a better utilization of the calorific values of the various combustion goods.
- tempering and in particular by cooling the grate plates the service life of the combustion grate can be increased considerably.
- the combustion grate according to the invention is simple and much cheaper to produce with individual grate plates than conventional combustion grates, which consist of a large number of grate bars which can be moved relative to one another and which are also exposed to high mechanical and thermal wear.
- the problematic dilatation is practically eliminated by keeping the temperature constant at a comparatively low level, which means that the previously complex measures to compensate for these heat-related dilatations are no longer necessary.
