Definitions

  • the invention is a method for automatic adjustment the combustion of a waste incineration plant.
  • a method for controlling the combustion of fuel with a strongly fluctuating calorific value is known from EP 317 731 B1.
  • the water content of the fuel and / or the CO 2 content of the combustion gases is measured by the intensity of the radiation in the area of the feed point and the evaporation and degassing zone of the furnace.
  • the calorific value of the waste is determined from these values and the air supply is controlled as a function thereof.
  • the disadvantage of this prior art is that, in the case of very moist waste, the water content and the CO 2 content in the flue gas also decrease due to a considerably poorer combustion. With automatic firing control, however, this can mean that, contrary to reality, the waste appears to be much drier.
  • expensive opto-electrical sensors are required to detect the water content or the CO 2 content.
  • the invention overcomes the disadvantages mentioned. It solves the task of creating a method for determining the waste quality that works simply and reliably. If a flue gas scrubber is available, the method should only use temperature, pressure and differential measurements (e.g. volume flow). It should also be easy to integrate into an existing waste incineration plant and be inexpensive. According to the invention, this is achieved in a method according to the preamble of the independent claim in that a fictitious process variable for setting the combustion parameters, such as combustion air distribution, waste layer thickness and rust rate Waste quality "is determined from the calorific value of the waste (Hu) and the water content of the waste (H 2 O waste ). If a flue gas scrubber is available, the method according to the invention makes direct measurement of the water content superfluous.
  • the water produced during the combustion can advantageously be determined via a statistical relationship between the heat of combustion and the mass flow of carbon.
  • the process can be easily and inexpensively integrated into an existing waste incineration plant, since all the necessary devices are usually already available. Despite the simplicity, it is a very reliable process.
  • the method according to the invention is suitable for determining the water content of the waste H 2 O waste and Calorific value of garbage Hu a fictional size in a waste incineration plant Waste quality "and thereby perform an automatic firing setting, for example in relation to essential variables such as the combustion air distribution, the thickness of the waste layer or the rust speed.
  • FIGS. 3 and 4 schematically show the first method step in a waste incineration plant 10 with a furnace 40.
  • This type of garbage throughput calculation also means that more or less always the same label 30 is loaded in the garbage shaft 50 (e.g. a weld seam, the deflection edge or the field of view of the camera). This means that the volume decrease between 2 loads corresponds to one gripper content.
  • the garbage calorific value Hu can be calculated using the boiler efficiency ⁇ boiler , the enthalpy of feed water h SPW and live steam h FD as well as the fresh steam quantity m ⁇ FD .
  • the flue gas moisture serves as the basis for determining the water content in the waste.
  • the proportion of water in the garbage cannot be detected directly due to the lack of suitable measuring systems.
  • the flue gas moisture must therefore also rise.
  • FIG. 5 The flue gas moisture H 2 O flue gas can be calculated for an existing scrubber from the flue gas temperature upstream of the scrubber and the saturation temperature in the scrubber.
  • FIG. 6 shows this process with the two temperature measurements.
  • the drier the flue gas the more water it can absorb and the lower the saturation temperature will be in the scrubber. If there is no scrubber, the flue gas H 2 O flue gas is determined directly, for example, using a measurement based on laser absorption (at the corresponding frequency).
  • the flue gas density ⁇ flue gas depends on the composition.
  • the density ⁇ flue gas 1.277kg / Nm 3 applies to the following (average) flue gas composition (volume percent): 14.5% H 2 O, 11% CO 2 , 7.5% O 2 , balance N 2
  • m H 2nd O_ smoke gas V Rauchgas_Kesselende ⁇ H 2nd O Flue gas ⁇ ⁇ H 2nd O_ steam
  • the C / H ratio is usually 7 to 8. With a constant value of 7.5 for the C / H ratio, the following relationship occurs:
  • H 2nd O_combustion air ( V PL + V SL + V False air ) ⁇ H 2nd O Combustion air
  • H 2 O combustion air is between 7..12g / Nm 3 and is assumed to be constant in this range.
  • the process is designed so that it can be used in any commercially available control system can be installed. It is based on no additional, special hardware or software reliant.
  • the grabs 3-10 with the weights w3-w10 are in the garbage shaft: w3 2950kg w4 3120kg w5 2760kg w6 2370kg w7 2590kg w8 3280kg 08:48 w9 2880kg 09:00 w10 3010kg
  • H 2nd O Flue gas f ( T Gas_vor_wascher , T Gas_in_washers ):
