Definitions

  • the invention relates to a method for controlling the combustion of Fuel on a grate of the type mentioned in the preamble of claim 1.
  • a generic method is known from WO 90/09552, in which with the help of a detector device in the form of a thermography or Infrared camera or a variety of individual detectors the temperature of the surface area formed on the grate is detected, d. H. on two-dimensional temperature profile is shown in individual rust zones and depending on the area distribution of the detected Measured values (temperature image) the supplied to the individual zones Combustion air and / or the transport speed of the fuel in is regulated in the individual zones.
  • a detector device in the form of a thermography or Infrared camera or a variety of individual detectors the temperature of the surface area formed on the grate is detected, d. H. on two-dimensional temperature profile is shown in individual rust zones and depending on the area distribution of the detected Measured values (temperature image) the supplied to the individual zones Combustion air and / or the transport speed of the fuel in is regulated in the individual zones.
  • Fuzzy control offers a way to control processes automatically and can be used in an advantageous manner if due to complex Process variables of conventional controllers are not sufficient.
  • the fuzzy control system allows to design a rule algorithm and in to implement a working controller, which is the one from the fire chamber measuring system provided data about the state of fire is analyzed and from it Control instructions are generated as they are without automatic regulation of the Surgeon based on his experience and judgment would give.
  • the Combustion air is split up into individual streams along the grate section Channels covering rust are fed to the fuel bed.
  • the setting of the Total air flow is through throttling devices, each of the channels are assigned and all adjusted equally via a servomotor become.
  • the fact that the combustion of the fuel along the The grate section is defined as a whole, and so is the combustion process can only be influenced as a whole, there is a risk that the Combustion zone from the grate to the waste disposal or from the grate to the Ashtray migrates, which ultimately leads to an uncontrolled combustion leads to high pollutant emissions.
  • This object is achieved in that the composition of the exhaust gases over the individual combustion zones and the amount of individual combustion air flows is regulated according to the fuzzy logic.
  • the exhaust gas composition in particular the O 2 , CO, CO 2 and / or NO x content, in addition to the bed temperature, also characterizes the advance of the combustion of the fuel in the individual zones.
  • control of the combustion process on the fire grate allows for the consideration of a multitude of indeterminate ones conditional factors, such as the burnout behavior of the fuel, different fuel composition, the fuel temperature below Inclusion of empirical values, as otherwise from an experienced The operator would have to be brought in manually for the regulation.
  • a further improvement of the method is achieved in that the Transport speed of the fuel in the individual zones after Fuzzy logic is regulated.
  • the zone-by-zone regulation of the Transport speed of the fuel bed offers the possibility of the bed stretch or compress as needed.
  • the invention is also directed to a device for regulating the Combustion of the type mentioned in the preamble of claim 3.
  • This device is characterized in that the Detector device detects the composition of the exhaust gas and the said devices are components of a fuzzy control system that the amount of the individual combustion air flows according to the area Distribution of the measured values regulates.
  • the detector device can have at least one thermography or Infrared camera for simultaneous detection of radiation across several zones exhibit.
  • the detector device can also have at least one gas analyzer with a gas sampling device for simultaneous detection of the Have exhaust gas composition over several zones.
  • FIG. shows a furnace 1 of a furnace 2 with a step feed grate 3, as in the prospectus "Combustion technology feed grate” (P 8303-05-13 / 1.Dg) der L & C Steinmüller GmbH, D-51641 Gummersbach (DE) is described.
  • the feed grate 3 has four combustion zones A, B, C and D, with zones B and C through a stage 4 are separated from each other.
  • the movable grate bars of the individual zones A - D are rust slides A5 - D5 assigned.
  • the rust slides A5 - D5 are about schematic shown adjusting devices A6 - D6 back and forth slidable.
  • Zones A - D are combustion air ducts A7 - D7, respectively assigned to those primary streams via line A8 - D8 Combustion air via control flaps A9 - D9 with Actuators A10 - D10 and flow measuring devices A11 - D11 can be fed.
  • the total amount of primary combustion air is over a Line 8 with a control valve 9 with actuating device 10 and a flow measuring device 11 supplied.
  • the dated Combustion grate 3 rising smoke gases can still over a line 8 'with control valve 9' with adjusting device 10 'and flow measuring devices 11' secondary air over several nozzles 12 are supplied.
  • the fuel 13, in particular garbage, is via a Feed hopper 14 and a feed device 15 with Actuator 16 the grate 3 in the area of the first Grate zone A abandoned and along the grate section below Spread to a fuel bed covering the grate 3 17 by operating one or more Rust slide A5 - D5 transported.
  • grate 3 it is also envisaged to design the grate 3 in multiple lanes.
  • the individual tracks are parallel to each other arranged and designed in the same way.
  • the combustion process of the fuel 13 on the grate 3 becomes essential by the location of the combustion and the Distribution of the combustion on the grate 3 determined.
  • the progress of combustion can, if necessary, be done by the individual Rust zones A - D more or less with primary Combustion air can be applied.
  • the individual rust slides A5 - D5 at each different speeds or by operating only single rust slide A5 - D5 the fuel bed 17 at Need to be compressed or stretched. With multi-lane It is possible to rust the fuel bed across the grate compress or stretch.
  • the single detector device a variety of Includes individual detectors, which in groups or individually are assigned to the respective rust zones. As individual detectors come with photodiodes, photodetectors and gas analyzers upstream rake-like gas sampling device in Question.
  • the Actuators A10 - D10 for adjusting the primary combustion air partial flows and / or the Actuators A6 - D6 for moving the Rust slide A5 - D5 for the transport of the Fuel 13, 17 according to the determined target values controlled.
  • FIG. each only one signal line shown completely.
  • the individual primary combustion air partial flows each set so that it always exceeds the setpoint predetermined share of the total primary Combustion air.
