Definitions

  • the invention relates to a method and a device for incinerating waste according to the preamble of claims 1 and 9.
  • Waste as fuel is very inhomogeneous in its composition. Their properties such as calorific value, ignitability and burning rate fluctuate in a very wide range.
  • Waste is incinerated, which consists, for example, of organic residual waste, industrial waste, wood, stones, plastics, glass, ceramics, paper and cardboard.
  • the waste is provided for incineration in such a combination that it always contains a certain amount of combustible components.
  • the waste intended for incineration is available in different sizes. In addition, they have different proportions of water, which must be taken into account when burning.
  • the compositions and chemical-physical properties of fuels such as coal, gas and oil are known. In contrast to the waste mentioned above, it is easily possible to optimize an incineration plant for these fuels.
  • Incineration plants for waste have so far mostly been operated with a low degree of automation.
  • a control room is provided, which is looked after by at least one surgeon.
  • the operator is responsible for adapting the combustion control to the fuel that is produced. He is dependent on his personal observation of the combustion process.
  • at least one video camera is provided, which is arranged above the combustion chamber. Corrective interventions in the combustion process can, however, only be made retrospectively, ie when a change in the composition of the waste to be incinerated has become noticeable through a change in the quality of the incineration. Then it is usually too late for corrective interventions. Such a combustion process will always fluctuate more or less strongly around its optimal operating point.
  • EP-A-0 317 731 it is proposed to observe the area of the waste application on the combustion grate with optical radiation receivers, which are preceded by optical filters which selectively detect the electromagnetic radiation emitted by H 2 O or CO 2 molecules.
  • the indicator for the water content of the waste obtained in this way is fed to the control device as a disturbance variable for controlling the combustion.
  • a signal is obtained which provides information about the water content of the waste before the waste is incinerated, so that the combustion parameters can be adapted directly to the incinerating waste.
  • a disadvantage of this process is that the time from the drop in the waste in the drop zone to the incineration on the grate is too short for changes in the combustion parameters to have a positive effect.
  • the dead times in this process are of the order of 30 to 60 minutes.
  • the transport time from the waste disposal area to the main incineration zone is in the range of 10 minutes.
  • the water content of the waste is only determined from the water evaporating on the surface. The water contained in the waste is not recorded and can therefore not be taken into account when controlling the combustion.
  • EP-A-0 352 620 describes a method in which the grate on which the waste is incinerated is observed with the aid of a video camera.
  • the video image obtained is automatically processed by means of a computer.
  • Information about the course of the combustion such as, for example, the temperature distribution and the location of the main fire zone, is derived from the signals obtained from this and is then fed to the process control system as a control variable.
  • the invention is therefore based on the object of demonstrating a method which enables a forward-looking manner of incinerating waste of all kinds, so that it is known even before the incidental waste is incinerated which parameters the furnace is to be set to.
  • the invention is also based on the object of demonstrating a device with which this method can be carried out.
  • a corresponding device for incinerating waste is disclosed in claim 9.
  • incinerate waste The best way to incinerate waste is to determine the composition or nature of the waste before incineration, and to ensure that its incineration is fully tailored to this information.
  • One of the most important factors for optimal combustion is knowledge of the water content of the waste. If the water content of waste due for incineration is known both on its surface and in its interior, the incineration can be controlled in advance without major problems.
  • the water content of the waste to be incinerated is determined a few minutes before incineration with the aid of microwave signals.
  • the determination of the water content of the waste takes place in the allocation shaft, in such a timely manner that the information obtained is completely available during incineration.
  • microwave signals are emitted perpendicular to the direction of conveyance of the allocation shaft, in which the waste is transported to a grate provided for incineration.
  • the water content of the waste causes signal weakening and / or phase changes in these microwave signals. These are evaluated to determine the water content in the waste.
  • microwave signals are transmitted from a first inner wall of the allocation shaft to the opposite wall and received there.
  • the microwaves sent through the waste experience a signal weakening and / or phase change.
  • the water content of the waste just examined is then determined from this by comparing the transmitted and received microwave signals.
  • the information signals obtained are forwarded to a process control unit.
  • microwave signals can also be transmitted perpendicular to the conveying direction of the allocation shaft and the microwave signals reflected on the waste can be evaluated for the determination of the water content.
  • the information signals determined from this are also fed to the process control unit.
  • a standing microwave can be formed between two opposite walls of the allocation shaft and the water content of the waste can be evaluated in a corresponding manner from the signal weakening and / or phase change of this standing microwave.
  • the microwave signals that are required for the upgrading are forwarded to evaluation units. The measured values determined by these evaluation units are stored in the process control unit.
  • the device for incinerating waste is equipped with an allocation shaft, which is followed by a feed slide. It is used to convey the amount of waste to be incinerated to a grate provided for this purpose, to which air is fed to maintain the incineration.

  • the evaluation unit 16 to which the microwave transmitter 7S and the microwave receiver 7E are connected, the water content in the waste 20 is determined from the signal weakening and / or phase change of the received microwave signals compared to the transmitted microwave signals.

  • a combined microwave transmitter / receiver module 8 is also installed at a defined distance below the microwave transmitter 7S on the inner wall 2A of the allocation shaft 2. This sends out microwave signals.
  • the microwave signals reflected at the waste 20 are received again by the module 8.
  • the microwave signals sent and received by the module 8 are fed to the evaluation unit 17. This determines measured values from the signal weakening and / or phase change between the transmitted and the reflected microwave signals, which are passed on to the process control unit 18. All measurement signals transmitted from the evaluation units to the process control unit 18 are stored there. They are available for the combustion of the waste 20 for controlling the air supply to the grate 4.
  • the waste 20 contained in the allocation shaft 2 is conveyed onto the grate 4 for incineration with the aid of the feed slide 3.
  • the amount of waste 20 that is loaded onto the grate 4 corresponds to the amount of waste that is currently in the dimensioning section 30 of the allocation shaft 2.

This means that the control of the supply of air for the combustion of these wastes 21 and 22 is tracked according to a value permanently stored in the process control unit.
