Definitions

  • the invention relates to a method according to the preamble of patent claim 1.
  • the control of the combustion in waste incineration plants, the combustion gases of which are usually passed through a heat exchanger in the form of a steam generator, is currently largely manual.
  • the operator observes the combustion process on the grate and varies according to parameters that influence the combustion process, such as the distribution of the primary combustion air supplied under the grate to the zones, the conveying speed of the fuel in the zones, and other such parameters.
  • the calorific value correlates only to a very limited extent with the density of the burning layer.
  • the primary object of the invention is to reduce the dead time in the control. Secondly, the combustion should also take place at different calorific values so that the garbage is really burned completely at the downstream end of the grate, which in turn allows a reduction in pollutants in the exhaust gases and a noticeable reduction in air consumption.
  • the document FR-A786.908 discloses a device for regulating the combustion of a fossil fuel, in which a heat radiator in the exhaust stack is directed at a heat receiver transversely to the direction of flow.
  • Either the air supply or the fuel supply is regulated in order to optimize the air-fuel ratio. It is obvious that this device can only be used for fuels of at least approximately constant calorific value.
  • Patent Abstracts of Japan Volume 6 # 101 (M-135) (979) dated June 10, 1982 discloses that the waste density and the fall rate of the waste in a shaft in front of the combustion zone are used as measurement variables for the combustion control in waste incineration.
  • Patent Abstracts of Japan Volume 5 # 131 (M-84) (803) dated August 21, 1981 relates to the control of the combustion of dewatered sewage sludge, the temperature of the combustion, the fuel throughput, the air throughput and the fuel weight being evaluated as measured variables.
  • Patent Abstracts of Japan Volume 10 # 191 (M-495) (2247) dated July 4, 1986 discloses to monitor the burnout level during waste incineration by means of a video camera and to compare it with a predetermined size, after which the air supply is adjusted according to the deviations becomes.
  • the invention is based on the knowledge that in most cases the water content of the fuel is a characteristic indicator of its calorific value; for fuels with low water content and low calorific value, such as rubble, glass, metals, it is advisable to also record the CO2 content of the combustion gases as early as possible; if necessary, the detection of only this CO2 content is sufficient.
  • a much better control of the heat output can be achieved if the product of the calorific value - determined preferably according to claim 1 - and the density of the fuel is evaluated as an input variable.
  • timing chains can of course be suitably supplemented to closed control loops.
  • the bands for H2O and CO2 allow characteristic values for the temperature of the combustion gases to be derived, while the acquisition of further bands, such as SO2, NO x , CO etc., make predictions with regard to enables the pollution of the gases and thus allows the flue gas cleaning systems usually provided today to be set to Optima.
  • FIG. 1 shows the garbage feed chute 10, a feed device 12 in the form of a reciprocating slide, the grate 14 in the form of six rollers, which are arranged one behind the other, axially parallel, and the ash discharge 16.
  • the steam generator 18 provides in connection with the invention no special features.
  • Below the grate are primary air supply lines 20, each of which, as can be seen in FIG. 3, is subdivided into a "right” and a "left”, separately controllable half.
  • a pressure measuring device 22 is arranged in each of the first two air supply lines 20a, the measured value of which fluctuates depending on the throttling of the flow through the fuel in the layer lying above the first two rollers and thus allows its average density to be determined.
  • the fuel volume used can be kept somewhat constant by accelerating or decelerating the entry by means of a slide 12.
  • the first two rollers which define the evaporation and degassing zone, there are observation lances 26 in the walls 24 on both sides, at the outer end of which measuring sensors are provided with upstream filters and downstream electronic processing circuits.
  • the selection of sensors and / or filters is made.
  • the band radiation is interested in H2O, and / or CO2, at a relatively low temperature in the range of e.g. 300..500 ° C, and the opto-electronic devices must be bent accordingly. (The same applies to the observation of the combustion and the ashes, as a matter of course).
  • the lances are directed to the "right" or "left” side of the grate, so that both sides are detected separately; this cannot be seen in the section according to FIG. 3, which lies approximately in the plane 3-3, but this applies analogously to the observation lances in the further zones.
  • At least one pair of observation lances 28 is in the combustion zone above the middle two rollers of the Grate 14 attached, and at least one further pair of observation lances 30 is located above the burnout zone, that is, above the last two rollers.
  • the combustion process is observed via the lances 28, most advantageously in the flame front, while the lances 30 serve primarily to measure the temperature for the ash discharge.
  • the calorific value of the fuels in an area comprising the feed point and the evaporation and degassing zone is determined from properties of the combustion gases by means of a non-contact measurement method, that the density of the fuel on the grate is determined in the same area, and that Fuel feed is controlled depending on the product of the two quantities determined in the direction of constant heat output; that a controlled parameter is the distribution of the primary air over the individual zones; that a controlled parameter is the fuel mass distribution over the individual zones; that a controlled parameter is the fuel feed volume per unit time; that a controlled parameter is the distribution of secondary air supplied above the grate over the individual zones; that one of the controlled parameters is the combustion air volume supplied per unit time; that one of the controlled parameters is the temperature of the combustion air supplied; that one of the controlled parameters is the distribution of combustion air across the conveying direction; that one of the controlled parameters is the distribution of the fuel mass across the direction of delivery; that one of the controlled parameters is the proportion
