Definitions

  • the present invention relates to methods and installations for incinerating waste comprising in particular large proportions of products which are difficult to destroy by simple combustion.
  • the invention overcomes these drawbacks by allowing industrial or domestic waste to be brought to the temperatures necessary so that there is no unburnt residue, while spending as little energy as possible.
  • the waste incineration process according to the invention is defined in claim 1.
  • the ash and unburnt bath which is brought for example to a temperature of at least 1500 ° C., and in particular of 1700 ° C., makes it possible to store the heat supplied by an electroburner and to transmit this heat by conduction, d 'a very effective way, to the waste that falls into the bath.
  • the calorific mass of the bath makes it possible to absorb the differences in the quantities of heat required by the composition and by the variable arrival of waste in the bath.
  • this bath has a relatively large surface to which the heat radiated by the electroburner is transmitted in a very efficient manner, in particular when the latter is arranged so that its flame extends near the surface of the bath. .
  • An electroburner is a gas burner with an electrical energy supply, as described for example in French patent application 89 06 560, which is included in the present specification by reference.
  • This gas burner with electrical energy supply essentially comprises a gas burner comprising a fuel inlet and an air inlet and, downstream, two electrodes between which an arc flows which provides additional energy to the burner flame.
  • the flame obtained by the combustion of natural gas with cold air and at stoichiometry is at a temperature of the order of 1450 ° C. With the heat input provided by the electric arc, the temperature rises and can reach 2700 ° C.
  • the flame obtained is of large size and has a very high radiation energy, which allows the heat to propagate well to the large free surface of the bath, unlike focused heating devices of the plasma type.
  • the invention also relates to a waste incinerator defined in claim 3.
  • the pocket is below the oven and the latter comprises, in the unloading zone, an inclined plane connected to the pocket. It then suffices to push the waste into the zone of its loading to push it little by little, after they have undergone a first combustion, on the inclined plane which they roll down by themselves to fall into the bath.
  • the bath overflows through an overflow in a basin of water.
  • the quantity of the bath is thus limited automatically and the ashes and unburnt melted are vitrified, as usual.
  • the electroburner is arranged closer to the overflow than to the inclined plane. The overflow also acts as an obstacle so that the waste does not pass directly into the basin.
  • the incinerator comprises means for determining the amount of heat to be supplied by the electroburner, for example an indicator of the waste inlet flow rate or, preferably, a temperature probe of the bath, preferably a pyrometric probe.
  • a control circuit is provided for the device for supplying electrical energy to the electroburner, as a function of the signal emitted by the means for determining the amount of heat to be supplied by the electroburner.
  • the bottom of the inclined plane 7 delimits a pocket 10 provided with an overflow 11.
  • An electroburner 12 directs its flame on the free surface of the ash and unburnt bath contained in the pocket. This bath overflows from the overflow 11 and falls into a basin 13 filled with water where the molten magma breaks up into small vitrified pieces under the effect of the brutal thermal shock.
  • An extractor 14 permanently removes these vitrified elements.
  • a pyrometric temperature probe 15 detects the temperature of the bath contained in the pocket 10 and, by an electrical control circuit 16, controls the device 17 for supplying electrical power to the electroburner 12.
  • the electroburner essentially consists of two parts.
  • a gas burner 18 having a fuel supply duct 19 and an air supply duct 20 and, on the other hand, an electrical energy supply device essentially comprising two electrodes 21, 22, between which an arc 23 which brings the temperature of the flame coming from the burner 18 to a value which can be adjusted by the device 17.
  • a combustible product can be added to it before introducing it into the furnace, or else an additional supply of energy can be ensured by means of a burner located in the combustion zone.
