Definitions

  • the object of this invention is to provide a furnace suit-. able for incinerating a wide number of different waste products or refuse, for instance in the form of garbage, chemical waste, industrial waste, hospital waste.
  • the currently known incinerator plants are arranged and constructed to remove or incinerate only one of the kinds of refuse mentioned or in some cases a few of these kinds of refuse simultaneously.
  • the object of the invention is attained through a plant that is characteristic in that it comprises a) a grate section, b) a chute, c) a rotary kiln and d) an afterburning chamber, these sections being placed in succession in the intended travelling direction of the refuse, and in that separate openings are provided for each of the mentioned sections for feeding a specific waste product to one of the sections.
  • the lighter refuse such as household refuse, bark and industrial waste containing a large part of easily combustible materials can be burned in the grate section in a'manner known per se.
  • the refuse submitted from the grate section is dried up and thrown down into the rotary kiln from the edge of the last step grate.
  • further refuse in the form of, for instance, sludge, paint residue, oil or corresponding residual products from the petrochemical industry can be added to the "carpet" of refuse already thrown down on the chute.
  • This liquid waste is, distributed evenly over the large surface resulting from the waste dropped from the stepped grates.
  • the chute connecting the grate section and the rotary kiln can be provided with a bottom surface impermeable to waste, and at the bottom of said chute a number of burners can be placed for afterburning of the refuse conveyed from the grate section and for providing said refuse with a temperature sufficiently high for the succeeding combustion in the rotary kiln.
  • Said bottom surface impermeable to the waste ensures that the liquid waste fed to the chute is advanced to the rotary kiln.
  • the burners provided at the bottom of the chute make it possible to adjust the drying of the waste supplied from the grate section.
  • the kiln rotating around a downwards inclined axis can be provided with a conically pointed or confined outlet.
  • nozzles are provided in the afterburning chamber for feeding highly polluted waste water for combustion of the organic material therein and vaporization of the liquid component.
  • the quantity of heat in the flue gas from the rotary kiln is suitably used for decomposing even highly polluted waste water.
  • waste oil burners By placing one or more waste oil burners in the afterburning chamber, as suggested according to the invention, it is possible to use waste oil to increase the temperature in the afterburning chamber and thereby increase the effecti- vity of combustion of the mentioned polluted waste water.
  • the plant shown in fig. 1 comprises a grate section which collectively has the reference number 1, a chute which is indicated by the reference number 2, a rotary kiln 3 and an afterburning chamber 4.
  • the part of the waste intended for combustion and consisting of relatively light waste in the form of household refuse, bark or industrial waste having a relatively large content of easily combustible materials is fed through the firing shaft 7 at the end of the plant shown to the left of fig. 1.
  • the material thus fed falls down on the in-' clined step grates, two of which are shown on the drawing, said grates being indicated by the reference numbers 8 and 9.
  • the slag formed by the combustion is discharged in a manner known per se through the slag-sluices 10 and 11 placed underneath the grates.
  • burners 6 can be placed in the bottom of the chute 2, which burners can be used for obtaining a correct temperature of the waste supplied to the rotary kiln. At a correct temperature a melting of the product is obtained under complete decomposition of the chemical substances, resulting in a clean, sterile slag.
  • the rotary kiln 3 has a conically pointed outlet ensuring detention of liquid waste.
  • the dried out waste is oxidized at high temperatures in the rotary kiln, and thereby a complete combustion of the material is obtained.
  • an afterburning takes place of the gases which may not have been combusted in the rotary kiln 3.
  • the flue gas will be whirled up and a high degree of mixing will take place whereby a complete combustion is achieved even in the case of low air supply.
  • the invention is not limited to the characteristic features just shown and described, and it should be noted that it... will be possible for anyone skilled in the art to carry out a number of modifications, for instance, placing more rotary kilns in succession or parallel to each other, and providing a greater number of inclined chutes or step grates than the number shown on the drawing, as the idea underlying the invention, as mentioned in the above, is the combination of supplementary sections of combustion plants known per se and providing openings for feeding the waste to the very section in which the combustion takes place most effectively for the particular product.
