  • a multiplicity of small diameter tubes are used 110/8 A in the downstream part of the unit, with respect to combustion gas flow, and these tubes connect through [56] References cued a redistribution section to the larger diameter tubes UNITED STATES PATENTS around the flame-combustion section, whereby the in- 3,090,675 5/1963 Ruff et al. 23/277 c coming g stream passes entirely countercurrently to 3,353,919 ll/l967 Stockman 23/277 C the combustion gases and feeds directly into a plenum 3,484,189 12/1969 Hardison et a1...
  • the present invention relates to a simplified and improved form of thermal incinerator unit for treating a contaminated gaseous stream. More particularly, the improved design utilizes heat exchange tubing of two sizes, with relatively large diameter, self-supporting tubes encompassing the combustion zone to accommodate the incoming gas stream prior to its discharge to the burner zone and to the flame-combustion section.
  • thermal incinerators provide for heat recuperation in that the incoming contaminated gas stream is passed through one or more passageways to have a heat exchange relationship with the flame and/or hot gases from the combustion zone; however, most designs and constructions have incorporated an internal cylindrical wall or partition, that is spaced inwardly from the outer housing wall. Such partitions are necessarily large and since they are in high temperature zones they must be of a heat resistant alloy material so as to be expensive from both the metal and fabrication aspects.
  • incinerator is similar to my earlier design, such as described in U.S. Pat. No. 3,549,333, as well as related to the Hardison et al construction in US. Pat. No. 3,484,189, to the extent that the preheated incoming waste gas stream is channeled circumferentially around the burner cone and becomes mixed with the fuel stream to provide for 100 percent secondary air burning and, preferably, no utilization of primary air to the burner means and to the combustion zone of the apparatus.
  • both the aforesaid patented designs incorporate internal partitioning cylinders to help define the combustion and heat exchange sections of the units.
  • observation means into the combustion section of an incinerator and that with units having a large internal cylinder around the combustion zone it is difficult to have satisfactory observation ports to fully observe the flame conditions.
  • observation ports through the housing wall at positions providing a sight line between tubes.
  • the present invention provides a recuperative form of thermal incinerator unit for a waste gas stream, which comprises in combination, (a) an elongated confined housing with an internal axially positioned combustion section at one end thereof, and a heat exchange section at the other end thereof, (b) burner means with fuel inlet means thereto projecting through an end of said housing and into said combustion section, (c) a plenum section for preheated waste gases encompassing said burner means and opening into the burner end of said combustion section, (d) a plurality of spaced apart large diameter heat exchange tubes positioned longitudinally adjacent the interior wall of said housing and around said internal combustion section, with an open end to each tube discharging into said plenum section at said burner means while the opposite inlet ends of the tubes connect with a gas redistribution section hereinafter defined, (2) a multiplicity of small heat exchange tubes positioned within said housing and extending longitudinally therewith in said heat exchange section, (f) combustion gas passageway means from said combustion section provided around said large diameter tubes
  • the tube sizes and spacings within the combustion and the heat exchange sections of the unit may vary in accordance with the quantity of waste gas stream, its temperature, velocity, etc., and it is, of course, not intended to limit the invention to the use of any predetermined number of tubes within any one section.
  • the larger diameter tubes positioned around the periphery of the combustion section are preferably unsupported in an intermediate portion thereof and thereby necessarily have a relatively large diameter to be self-supporting for the length of a conventional combustion zone.
  • this intermediate gas redistribution section may comprise a small chamber with one wall section which serves as a tube sheet for the plurality of small diameter tubes transferring the incoming gas stream through the heat exchange section and an opposing wall section which serves to connect with the spaced larger diameter tube members passing around the combustion section of the unit.
  • this intermediate redistribution section may also serve as an intermediate support for the tube members, with such section being either fixedly or slideably supported from the inside wall of the housing whereby the tubular members can, in effect expand from one end of the housing to the other as one entire section.
  • FIG. 1 of the drawing is a longitudinal sectional elevational view showing one embodiment of the present recuperative form of direct flame incinerator where there is the use of two sizes of tubular members in an end-to-end relationship to accommodate the incoming gas stream.
  • FIG. 2 of the drawing illustrates in a partial sectional elevational view a modified arrangement with respect to the gas inlet and the gas outlet means from one end of the housing.
  • FIG. 3 of the drawing shows, in a partial sectional view, a means for adjusting the size of an air passageway means around the burner cone at the burner end of the unit, as indicated by the line 33 in FIG. 1.
  • FIG. 4 is a partial sectional view illustrating a means for slideably supporting an intermediate gas redistribution section within the interior of the housing, as indicated by the line 4-4 in FIG. 1.
  • an outer shell or housing 1 which has a contaminated gas stream inlet at 2 and a treated gas stream outlet at 3, both being at one end of the housing while a burner means 4 with fuel inlet means 5 is indicated as being provided at the opposing end of the housing.
  • the contaminated gas stream enters inlet 2 and distribution zone 6, which is defined by tube sheet 7 and conical end portion 8, such that there is gas flow into the multiplicity of small diameter tubes 9 to carry on into a redistribution section 10 within a central portion of housing 1.
  • the redistribution section 10 is defined by a vertical tube sheet 11, a conical portion 12 and a vertical plate 13.
  • the latter defines the downstream end of a combustion zone 14 and will generally be insulated by suitable high temperature insulation means 15 such that flame and hot combustion gases which may impinge thereon will be diverted around the redistribution section 10.
  • a plurality of larger diameter tube members 16 will be spaced around the periphery of the combustion section 14, spanning between the sloping tube sheet 12 and a vertical tube sheet 17 which is spaced from end portion 18 'of housing 1 to define a gas plenum section 19.
  • the contaminated incoming gas stream will pass longitudinally through housing 1 from one end to the other by way of tubes 9, redistribution section 10 and tubes 16 into the gas plenum section 19 to then flow into and around the perforated cone member 20 and thence into combustion section 14.
  • tube support plate 17 is provided with a central opening 21 entirely around the conical member 20 such that there is space for the flow of a major portion of the contaminated gas stream entirely around the latter to be able to mix with the hot combustion gases and flame being emitted from the end of said member 20.
  • suitable ignition means may be provided to effect the initiation of flame from the fuel gas stream entering by way of line 5. After ignition the fuel will be adjusted in accordance with the amount of combustible materials in the waste gas stream entering the unit such that there is sustained flame and combustion during all periods of operation.
  • the combustion gases from section 14, as shown by the arrows in the drawing, will be diverted over and around the plurality of tube 16 so as to flow through passageway means 22 extending around redistribution section 10 and then reach heat exchange zone 23 accommodating the multiplicity of smaller tubes 9.
  • Various types of baffled flow may be provided for the hot combustion gas stream entering the heat exchange zone 23 and it is not intended to limit the present invention to any one type of tortuous flow path for the combustion gas stream passing through the heat exchange section to the outlet means 3.
  • the small diameter tubes 9 are, in effect, connected to the interior ends of tubular members 16 through the redistribution section 10, it is to be noted that the resulting combination of tubes will thus tend to expand as one long unit.
  • expansion may be accommodated from one end portion of the interconnected tube arrangement or it may be from a central portion at the redistribution section 10, with expansion going each direction therefrom.
  • the tube bundles may expand from a fixed point at the tube support sheet 7, through the support means for redistribution section 10, and on through support means 26 in the tube sheet 17 at the burner end of the unit.
  • the tube support means 26 for each of the tubes 16 passing through sheet 17 can have adequate sizing to permit slideability for each of the tubes 16 and permit accommodation of expansion movements for the entire combination of tubes.
  • gas inlet means 2' is shown at the side of the housing 1 to discharge into an inlet distributing zone 6' which in turn feeds the incoming gas stream into the plurality of tubular members 9, while the gas outlet 3' is indicated extending axially through the end of the housing 1 from heat exchange zone 23 rather than from a side portion thereof.
  • gas outlet 3' is indicated extending axially through the end of the housing 1 from heat exchange zone 23 rather than from a side portion thereof.
  • Still other variations may be made in connection with the design and arrangement of gas inlet and gas outlet means for the present form of incinerator unit.
  • FIG. 3 of the drawing there is illustrated an adjustment means for effecting a change in the size of the opening 21 which extends circumferentially around the burner cone member 20 and into the interior of the combustion zone 14.
  • slideable members 29 and 30 may be slideably attached to the tube sheet 17 by bolt means 31 whereby there may be manual adjustment to effect the size of opening 21.
  • burner means may, of course, be utilized in combination with thermal incinerator units; however, as noted hereinbefore, it is preferable that the burner means utilize 106% secondary air for sustaining combustion and thereby eliminating the use of any primary air to mix with the fuel at 5, all of which can tend to lower the temperature of the flame and combustion gases being emitted from the burner means into combustion zone 14. It will, of course, be noted that the present arrangement and design provides for the customary three elements of combustion, comprising, time, temperature and turbulence.
  • a sustained time element is provided by incorporating an elongated combustion section 14 along with high temperature and turbulence which continues through the tortuous path for the combustion gas stream as it moves on downstream around the gas redistribution section into the heat exchange section and thence to the gas outlet means, all countercurrent to the incoming gas flow which is carrying through the successive flow paths provided by the small diameter tubes 9 and the larger diameter tubes 16.
  • An internal insulating layer 32 is indicated as being provided through the entire length of housing 1 as well as over end sheet 18 in order that there is a low wall temperature for the housing and a minimization of expansion. Where desired, there may, of course, be external insulation on the housing 1 to preclude loss of heat from the entire unit. It may again be reiterated that through the elimination of an internal, spaced cylindrical baffle member to define an internal combustion section, as well as the utilization of internal insulation for housing ll, there is a substantial elimination of alloy metal in the overall construction of the incinerator unit and an accompanying lowering of cost therefore.
  • a recuperative form of thermal incinerator unit for 5 a waste gas stream which comprises in combination,
  • burner means with fuel inlet means thereto projecting through an end of said housing and into said combustion section
  • a plenum section for preheated waste gases encompassing said burner means and opening into the burner end of said combustion section
  • combustion gas passageway means from said combustion section provided around said large diameter tubes and around said multiplicity of small tubes to be in heat exchange relationship there with,
  • waste gas stream inlet means to said housing and into one end portion of each of said multiplicity of small heat exchange tubes, whereby said waste gas stream flows countercurrently to the combustion gases
  • an incinerated gas stream outlet form said housing downstream from said combustion section and from said combustion gas passageway means.
  • thermal incinerator unit of claim 1 further characterized in that said intermediately positioned gas redistribution means comprises a confined plenumtype section with one wall portion serving as a tube sheet for said multiplicity of small heat exchange tubes and an opposing spaced spart walll section serving as a tube sheet for the plurality of large diameter tubes extending around said combustion section.
  • thermal incinerator unit of claim 2 still further characterized in that said gas redistribution section has bracket means extending therefrom to engage support brackets attached to the interior wall of said housing at positions opposing said redistribution section.
  • thermal incinerator unit of claim 1 further characterized in that movable plate means are positioned to encompass said burner means to vary the size of the opening into the burner end of said combustion section from said plenum section.
