Definitions

  • the invention is a method for automatic adjustment the firing of a waste incineration plant.
  • a method for optimized driving of a waste incineration plant which regulates the amount of air in dependence on the calorific value.
  • the combustion air can be adjusted in individual zones. This is done continuously to adjust the amount to a fluctuating calorific value.
  • the calorific value results from the quotient of currently released heat and the waste mass flow.
  • the CO and the O 2 content of the exhaust gas are included.
  • the water content of the waste is not considered disadvantageous in this process, although it plays a major role in combustion.
  • the invention overcomes the mentioned disadvantages. It solves the task To provide a method for determining the quality of waste, which is simple and works reliably. If a flue gas scrubber is present, the process should only temperature, pressure and differential measurements (eg volume flow) apply. It should also be easy in an existing waste incineration plant can be integrated and be cost effective.
  • this is achieved by setting a fictitious process variable "waste quality" from the calorific value of the refuse (Hu) and the water content of the refuse (H 2 ) in order to adjust the firing variables, such as combustion air distribution, waste layer thickness and rust velocity O garbage ) is determined.
  • a flue gas scrubber is by the inventive method the direct measurement of the water content superfluous.
  • Next can be beneficial over a statistical relationship between the heat of combustion and the Carbon mass flow determined by the combustion of water become.
  • the process is simple and inexpensive in an existing Waste incineration plant can be integrated, since usually all necessary equipment already available. Despite the simplicity, it is a very reliable procedure.
  • the inventive method is suitable by determining the values of water content of the waste H 2 O garbage and Calorific value of garbage Hu In a waste incineration plant to set a fictitious size "waste quality" and thereby make an automatic firing adjustment, for example, in relation to major variables such as the combustion air distribution, the waste layer thickness or the rust rate.
  • FIGS. 3 and 4 schematically show the first method step in a waste incineration plant 10 with a furnace 40.
  • This type of waste throughput calculation further requires that more or less always be loaded at the same mark 30 in the refuse chute 50 (eg, a weld, the deflection edge or the field of view of the camera). This means that the volume decrease between 2 feeds corresponds to a gripper content.
  • the boiler efficiency, En boiler , the enthalpy of feed water h SPW and live steam h FD and the live steam quantity m ⁇ FD of the garbage heating value Hu can be calculated.
  • the flue gas moisture serves as a basis for the determination of the water content in the Rubbish.
  • the water content in the garbage can not directly due to lack of suitable measuring systems be detected.
  • the flue gas moisture must increase. This process is shown in FIG.
  • the flue gas moisture H 2 O flue gas can be calculated with an existing scrubber from the flue gas temperature before scrubber and the saturation temperature in the scrubber.
  • the drier the flue gas the more water it can absorb and the lower the saturation temperature in the scrubber. If no scrubber is present, the flue gas moisture H 2 O flue gas is determined directly, for example, with a measurement based on laser absorption (at the corresponding frequency).
  • m H 2 O _ flue gas V Rauchgas_Kesselende ⁇ H 2 O flue gas ⁇ ⁇ H2O_Dampf
  • H 2 O_Verbrennungs Kunststoff ( V PL + V SL + V secondary air ) ⁇ H 2 O combustion air
  • H 2 O combustion air is between 7..12g / Nm 3 and is assumed to be constant in this range.
  • Figure 9 is a diagram showing some examples of how an error of garbage mass flow m ⁇ garbage, NCV and water mass flow m ⁇ H2O_müll changes in relation to the waste quality.
  • Waste quality f (Hu rubbish . H 2 O rubbish ) can the error from the calculation of the waste mass flow m ⁇ refuse completely hide or at least keep small.
  • the procedure is designed to fit into any commercial control system can be installed. It is not on any additional, special hardware or software reliant.
  • the grippers 3-10 with the weights w3-w10: w3 2950kg w4 3120kg w5 2760kg w6 2370kg w7 2590kg w8 3280kg 08:48 w9 2880kg 09:00 w10 3010kg
