Definitions

  • Is is the general object of our invention to provide a preferably portable incinerator for such materials adapted to burn even heavy and/or coated paper products, such as oil or wax papers, in a substantially complete and scotfree manner so that only smokeless flue gases are developed and the need for connecting the exhaust of the device to a chirnney is eliminated.
  • a more particular object of the invention is to realize these advantages in an incinerator free from grates, stokers and other movable arts.
  • an incinerator having a perforated shell which terminates at the top in a flue and forms at the bottom a combustion chamber in combination with that flue, the shell containing in the interior of the combusition chamber one or more inlets for supplemental combustion air.
  • Such an inlet advantageously takes the form of an upstanding tubular boss, preferably ot' generally frustoconical configuration like the surrounding shell, the tip of the boss extending approximately midway into a combustion zone defiined by a lower shell section above a bottom section designed to receive the cornbustible material.
  • the interior of the tubular boss cornmunicates with the exterior of the shell, e.g. through suitable conduitg or through a bottom aperture, so that air simultaneously enters the combustion zone from Within and without whereas a flarne started at the top of the rubbish pile Within the charnber spreads progressively downwardly with substantially complete conversion of the waste products into smokeless gases.
  • these gases escape upwardly through the fine, more air is drawn in through the peripheral shell perforations and the supplemental inlet means, this air being advantageously preheated by the preferably metallic walls of the inlet-forming boss.
  • Any fly ash or cinders entrained by the escaping flue gases can easily be intercepted and returned to the combustion charnber by a screen spanning the entrace to the flue Within the shell.
  • FIG. 1 is an elevational view, partly in section, of an incinerator emboclying the present improvement.
  • FIG. 2 is a sectional elevational view of a modified bottom section for such incinerator.
  • the incinerator shown in FIG. 1 comprises a shell composed of a cylindrical bottom section l, a lower frustoconical section 4 and an upper frustoconical section S, these sections being stacked upon one another so as to clefine a progressively constricted path for ascending combustion gases whereby the latter are thoroughly intermingled with the admixed air.
  • the ar enters the interior of the shell through several annular rows of perforatons disposed in different horizontal planes, such as the apertures Tic of section 1 and the apertures 4b, 4c of section 4.
  • Section 5 terminates at the top in a fine Se whose lower end is spanned by a screen 6.
  • Section 4 is provided with a series of latch fingers 4a, releasably engaging respective lugs le onsection 1, and with a top flange 4g similarly engaged by catches 5d on section 5.
  • Handles 4d on section 4 and 5 on section 5 enable these sections to be lifted ofl for filling and cleaning purposes.
  • AD inlet for supplemental air in accordance with this invention is provided in the shape of a frustoconical boss 3 rising off the bottom of section 1.
  • This boss whose walls are formed with numerous openings 3a, rises to substantially the median level of shell section 4 and is open at the bottom for communication with the atmosphere; as shown, it also has a narrow opening at the top.
  • the bottom of shell section 1, which constitutes a receptacle for the rubbish to be burned, is provided to this end with a central hole 1b receiving the base of boss 3.
  • This bottom raised above its supporting surface by legs 2, is also shown formed with numerous small perforations la through which further air can enter the interior of the shell.
  • Section 4, which as shown is of somewhat greater height than boss 3, is imperforate above the top of the boss, the rows of aperture 4b, 4C being confined to its bottom half.
  • the incinerator shown in FIG. 1 is filled upon removal of the upper or covering section 5 with the waste products to be burned, this material being then ignited before section 5 is put back in place.
  • the initial combustion stage results in the escape of gases through the flue Se and draws atmospheric air through the extermal shell apertures le, 41), 4C etc. and also through the openings 3a of the internal inlet 3.
  • the baffles 1d, le, 4 etc. prevent the flame from shooting out through the peripheral shell apertures.
  • Screen 6 will intercept any glowing particles rising toward the flue Se and return them to the interior of the shell for further combustion.
  • the updraft created within the shell wil1 generally be strong enough to prevent any solids from dropping through the bottom apertures la of receptacle 1; if desired, however, a pan designed to catch any falling ashes may be placed between the legs 2.
  • FIG. 2 we have shown a modified waste receptacle for our improved incinerator which has an imperforate bottoni supporting the boss 3, the interior of this boss communicating with the exterior of the shell portion 1' through a plurality of horizontal conduits 7.
  • the air entering through these conduits passes, as in the preceding ernbodiment, into the combustion zone of the shell through the apertures 3a of the boss.
  • the legs 2 of FIG. I have been omitted in this arrangernent.
  • A11 incinerator for combustible waste materials comprising a generally conical shell surrounding a combustion chamber, said shell converging upwardly and terminating at the top in a centrally positioned fine communicating with said chamber, said shell being further provided with peripheral apertures for admitting air into said chamber, and inlet means for additional air positionecl Within said shell near the bottom of said combustion chamber, said inlet means comprising at least one centrally positioned upstanding perforated tubular boss within said combuston charnber, the interior of said boss communicating With the exterior of said 511611, said boss converging substantially conically toward the top, said she11 being composed of a bottom section and a p1ura1ity of frustoconical sections stacked upon one another, aid sections being provided With fastening means for releasab1y interconnecting them, said boss rising from said bottom section to substantially thc median 1eve1 of the next higher section, the 1atter being of a height exceeding that of said boss and having said peripheral apertures d
  • An incinerator for the self-combustion of combustib1e was te materials, comprising an annu1ar upport section having air-inlet means distributed peripherally about said support section, and an axial1y extending centrally disposed upstanding perforated tubular boss having a generally conical configuratioh, said boss being provided With an in1et for admitting air through the perforation thereof to the interior of said support secton; an upright bi-partite combustion-chamber shel1 mounted on said support section, said she11 comprising a frustoconical 1ower section for containing waste material mounted on said annular support section With said boss projecting into said lower section over at least half the axial 1ength of said lower section, said Iower section being provided With a multiplicity of peripheral air-inlet apertures disposed in a relatively narrow band at a lower portion of said Refercnces Cited by the Examiner UNITED STATES PATENTS 920,312 5/09 Fox -18 950,
