Definitions

  • the invention relates to a method for regulating the Fire performance of incineration plants, in particular waste incineration plants, at the kiln at the beginning of a firing grate abandoned, on this one drive and locomotion subjected and at the end of the grate the accumulating Slag is discharged.
  • a regulating device regulates the feed quantities of the fuel and the Schürzi of the grate and the amount of primary air based on the Kiln index for each zone, one previously known Setpoint for the thickness index is set, about the thickness of the firing layer in the individual zones of the grate to regulate.
  • the object of the invention is a method by simple means to provide, in which the firing capacity is relatively accurate adapted to the steam power requirements can, with essential, firing requirements with regard to the exhaust gas composition and here in particular with a view to CO, hydrocarbons, nitrogen oxides as well other harmful substances should be met.
  • the fuel mass distribution can be adjusted so that the air permeability of Feuerungsrost and fuel bed remains constant, which leads to a stable excess of air and thus to a largely constant combustion with stable O 2 values in the exhaust gas. Furthermore, this consistent emissions of pollutants are achieved at a low level.
  • the gas velocities through the fuel bed remain largely constant and thus a constant amount of low Flugstaubaustrag from the furnace is achieved. Since the combustion process can be kept at a uniformly favorable level by the measure according to the invention, this results in a good slag burnout even during the combustion of difficult waste with large differences in calorific value.
  • This specified type of calculation of the controlled variable is basically sufficient for the solution of the problem set in the beginning.
  • deviations from the actual conditions may occur, which are due to the fact that the combustion air resistance body combined from the grate covering and the fuel bed opposes these more or less strong flow or frictional resistances depending on the flow velocity of the combustion air flowing through it.
  • the air flows on the one hand through very narrow gaps between the individual grate bars of the combustion grate and on the other hand by existing from waste or rubbish bed, which offers no defined flow paths and their air permeability not only by the height of the fuel bed, but also by the composition of the fuel mass ie depends on the quality of the waste.
  • flow conditions occur which can no longer be exactly determined by mathematical formulas and which lead to the calculation bases not always coinciding with the actual conditions.
  • the experimentally determinable flow coefficient is therefore one Correction variable, the flow losses due to friction and Vortex formation for the air flow through the grate coating, i. through the grate made of individual grate bars and the fuel bed, which is made of an irregular Accumulation of combustible and inert waste of the most different magnitude exists.
  • the incinerator shown in Figure 1 comprises a Feuerungsrost 1, a charging device 2, a firebox 3 with subsequent throttle cable 4, to which more throttle cables and the incinerator downstream units, in particular Connect steam generation and emission control systems, which are not shown and explained in detail here.
  • the Feuerungsrost 1 includes individual grate levels 5, which in turn formed from individual, adjacent grate bars are. Every second step of the grate designed as a return grate Firing grate is designated with a total of 6 Drive connected, which allows the speed of attack adjust. Below the firing grate are subdivided both longitudinally and transversely Unterwindschn 7.1 to 7.5 provided that separated Primary air is applied via individual lines 8.1 to 8.5 become. At the end of the firing grate the burned out Slag by means of a slag discharge device, shown Embodiment of a slag roller 9 in a Schlack diligentchacht 10 discharged, from where the slag falls into a non-illustrated detoxifier.
  • the loading device 2 comprises a feed hopper 11, a task chute 12, a feed table 13 and one or several adjacent, possibly independently adjustable feed piston 14, the in the task chute 12th sliding down garbage over a feed edge 15 of the feed table 13 in the firebox 3 on the grate 1 slide.
  • the heaped on the grate 1 fuel 16 is pre-dried by coming from the lower wind zone 7.1 air and by the radiation prevailing in the furnace 3 radiation heated and ignited.
  • the underwind zones 7.2 and 7.3 is the main fire zone, while in the area of Underwind zones 7.4 and 7.5, the forming slag burns out and then enters the slag chute 10.
  • the first approximation the free air outlet surface through the grate surface and the fuel bed is equivalent, are in the air supply line 8.2 a Heilmengenmeß worn 18 and in the underwinding chamber 7.2 a temperature sensor 17 and a pressure sensor 19 provided while in the firebox 3 another Pressure sensor 20 is arranged to the static pressure difference between the underwind zone and the firebox can.
  • various actuators are in Figure 1 indicated that for controlling various influencing variables or devices serve to the desired regulation to carry out the fire performance. It is the Adjusting device for influencing the speed of attack with 21, for influencing the speed of the slag roller with 22, for the on and off frequency and the speed the feed piston with 23 and for the primary air quantity denoted by 24, which is capable of each one Submersible chamber to supply the required amount of primary air.
  • a hitherto conventional control unit RE which is capable of Fire performance of a combustion plant, for example, depending from the steam mass flow with regard to the fuel application and the primary air supply, to only a few control parameters to call, to regulate, is arranged so that the required for carrying out the process according to the invention Target values and the determined actual values in form of control variables passed on to the individual control devices can be.
  • This is a central processing unit ZR provided with the temperature sensor 17, the Heilmengenmeß worn 18 and the two pressure sensors 19 and 20 communicates and those of these sensors or devices processed measured values.
  • the central computer ZR determined So the actual size of the free air outlet surface, which then in the control unit RE with the setpoint value for this free air outlet surface is compared, from which then the signal for influencing the individual actuating devices 21 to 24 results.
  • This value thus obtained is the actual value of the free air outlet surface and is provided as a control signal F or R of the control unit RE, where this value is compared with the setpoint value for the free air outlet surface F.
  • the value required due to the control signal R is compared with the target value range for the warping speed to ensure that corrections or Stell intimide only in plausible and permissible areas.
  • FIG. 3 shows the result of the control method according to the invention.
  • the free air outlet surface F is plotted as a control signal and also the number of strokes per hour and on the abscissa the measured time.
  • F set the constant setpoint value for the free air outlet area is shown.
  • the curve F represents the respective actual values of the control signal R K corrected with the flow coefficient ⁇ . It can be seen that there are only relatively small fluctuations with respect to the predetermined desired value, which leads to the conclusion that this combustion runs almost evenly.
  • the speed of the grate is shown as the number of strokes of the grate drive 6 per hour.
  • a reduced free air outlet area means that the air permeability of the fuel bed is reduced either by an increased fuel bed height or by a greater compactness of the fuel mass due to moist, inert components.
  • control techniques of the present invention are not only related to the speed of rusting, although this is the main influence.
  • the combustion cycle can be largely made uniform by regulating the speed of the burn, it is also necessary to influence the feed quantity of the fuel mass on the furnace grate and the discharge rate of the slag as a function of the explained control signal R or R K.
  • the control unit RE not only on the adjusting device 21, the speed of attack, but also on the adjusting device 23, the feed amount of the fuel to the furnace grate 1 and the adjusting device 22, the discharge via the discharge roller 9.
  • the adjusting device 24 can also be made to influence the amount of primary air, this influence emanating primarily from the usual fire power control.
  • the control method according to the invention can be used as an independent Control method at least based on the rust speed but it can only be used as a correction serve for the regulation of the Schür für, if these due to other parameters over the usual fire power control unit is regulated.
