Definitions

  • the present invention relates to an incineration plant of the kind set forth in the preamble of claim 1.
  • DK-B-154 452 (corresponding to EP-00 68 319) belonging to the applicants discloses a plant of this kind, in which the rotary kiln is connected to the exit end of the incineration grate by means of an inclined chute, via which that part of the waste material not yet having been incinerated but merely pre-dried is made to fall down into the rotary kiln, in which it is incinerated so as to form a pure sterile slag.
  • DK-B1-168 245 discloses a method and a plant of a similar kind, in which a rotary kiln is placed immediately downstream of an incineration section with stepped grates, and in which a glass-like product is formed in the rotary kiln, and it is evident from this document, perhaps most clearly from its abstract, that the intention is to convert the solid products or combustion resulting from the incineration into a glass-like mass, from which salts and heavy metals cannot be leached.
  • the problem having been solved with the plant described in this document is that of providing an after-treatment of these solid products of combustion in such a manner, that they can be deposited or possibly recycled without placing a load upon the environment.
  • the incineration plant shown in Fig. 1 comprises furnace walls 1, between which is placed a stepped incineration grate, the lowermost grate section 2 of which may be of the kind described in applicants' GB-B-2 120 764, comprising grate blocks placed in alternate reciprocable and stationary rows.
  • the reciprocable grate blocks in the grate 3 are operated by a motive mechanism 4.
  • the grate 3 leads into the infeed opening of an after-treatment unit in the form of a rotary kiln 5, the rotational axis 6 of which is inclined-downwardly in the downstream direction and the exit end 7 of which, being conically narrowed on the inside, debouches into a shaft 8 for collecting the liquid vitrified slags and ashes flowing down from the exit end 7 of the rotary kiln 5.
  • a burner 9 is placed in the wall of the shaft 8 so as to face the exit end 7 of the rotary kiln 5 for controlling the temperature of the vitrifierd mass. Hot flue gas from the furnace space and/or air for combustion may be conducted to the exit end 7 of the rotary kiln 5 via the slag shaft 8 by means of suitable ducts (not shown).
  • the incineration plant shown in Fig. 1 operates in the following manner:
