  • flue gas cleaning apparatus In an effort to comply with regulatory air pollution codes, more recent incinerator designs have provided for cleaning the gaseous products of combustion prior to their discharge to'atmosphere. Such flue gas cleaning apparatus is usually of costly and bulky construction and in some cases has not operated to clean the flue gases sufficiently to comply with the regulatory codes.
  • One known flue gas cleaning apparatus includes means for conducting the gaseous products of combustion through water sprays so that the suspended ashes and other particulate matter are entrained in the water which is then collected and conveyed to a suitable clarification system. This type of flue gas cleaning apparatus is expensive and complex and contributes not only to the high cost and massive structure of prior art incinerators but also to water pollution.
  • One known apparatus for accomplishing this function comprises a conveyor disposed beneath the combustion chambers for receiving such material and for conveying the same from the combustion chambers to a suitable disposition area.
  • Such conveying apparatus is also very costly and in addition occupies considerable space which further contributes to the high cost and massive structure of prior art incinerators.
  • an incinerator which includes a combustion chamber having spaced end walls and a side wall with its central longitudinal axis extending between the end walls.
  • the chamber is preferably disposed in operative position with its central longitudinal axis extending horizontally or substantially horizontally.
  • Means are provided for introducing waste material and primary air into the chamber for establishing a vortical move ment of the waste material toward one of the end walls and provision is made for igniting the waste material during its vortical movement.
  • Secondary air is introduced into the chamber substantially tangentially to the side wall at a plurality of regions which are spaced substantially throughout the entire length of the chamber and which are aligned along a horizontal axis.
  • These regions are located adjacent the bottom of the chamber at one side thereof such that secondary air is introduced in directions to maintain the vortical movement of waste material.
  • the secondary air entering the chamber at each of the mentioned spaced regions is controlled by an independently controllable damper which can be adjusted manually to control the amount of air entering the chamber and contributing to the vortex energy at each region.
  • the secondary air is supplied through a blower-feed manifold and an automatically controllable damper controls generally the secondary air distributed through the manifold.
  • the automatic damper is controlled adjustably and operates automatically in response to temperature variations in the chamber.
  • a discharge flue port has an open end opening in the of the side wall for discharging from the chamber during the burning process non-combustible material entrained in the outer region of the vortex.

  • the incinerator of the present invention is particularly suited for disposing of solid industrial and municipal waste material such as for example, paper, peanut hulls, cardboard cartons, wood scrap, garbage, foliage, bottles, cans and combustible floor sweepings.
  • solid industrial and municipal waste material such as for example, paper, peanut hulls, cardboard cartons, wood scrap, garbage, foliage, bottles, cans and combustible floor sweepings.
  • the incinerator is also capable of disposing of liquid waste material such as oils, paint sludges and plating tank residue.
  • the incinerator as schematically shown in FIG. 1 includes a size reduction unit 10 designed to shred and chop the waste material into pieces small enough to be efficiently conveyed to and burned in the combustion chamber. If the waste material to be disposed of is already of an acceptable size, such as sawdust, then the size reduction unit 10 is not required.
  • the size reduction unit 10 may be of any suitable construction and includes a hopper 12 having an open end 14 into which the waste material is fed for size reduction by a shredding and chopping mechanism (not shown) operated by a motor (not shown).
  • the waste material After being reduced in size the waste material is drawn into a pneumatic conveying system including a blower l6 operated by a motor (not shown) which entrains the size reduced material in a primary air stream and transports it through a pipe 20 which opens into a combustion chamber 22.
  • a blower l6 operated by a motor (not shown) which entrains the size reduced material in a primary air stream and transports it through a pipe 20 which opens into a combustion chamber 22.
  • the combustion chamber 22 may be of any suitable configuration and is preferably cylindrical including a pair of spaced end walls 24 and 26 connected by an annular side wall 28.
  • the chamber 22 is preferably disposed when in operative position so that its central longitudinal axis which extends between the end walls 24 and 26 is horizontal or substantially horizontal as shown in FIGS. 3 and 4.
  • the end wall 26 of the chamber 22 may include an access door 30 to permit access to the interior of the chamber 22.
  • the side wall 28 of the chamber 22 comprises an outer casing 32 (FIG. 3) formed of suitable material such as a low carbon steel and the casing 32 is lined with one or more inner layers 34 and 36 of suitable material such as fire brick.
  • the innermost layer 34 is designed to exhibit good resistance toabrasion whereas the layer 36 may be designed to have good heat insulating qualities or to transfer the heat to a remote location.
  • the end walls 24 and 26 of the chamber 22 may be similarly formed of an outer layer of low carbon steel with inner layers of tire brick.
  • the pipe 20 enters the chamber 22 tangentially of the side wall 28 near the top of the chamber 22 adjacent the end wall 26 and at the left side of the chamber as viewed in FIG. 2. In certain installations it may be desirable to have the pipe 20 enter the chamber 22 at a region which is substantially midway between the end walls 24 and 26.
  • a suitable gas burner 38 is disposed near the end wall 26 of the chamber 22 to fire tangentially into the chamber adjacent the top and at the right side thereof as viewed in FIG. 2. Under conditions wherein a mixture of waste material and air is continuously fed into the chamber 22, it has been observed that the burner 38 may oridinarily be turned off after ignition of the waste material is accomplished.
  • the location of the burner 38 shown in FIG. 2 is not our invention but is the sole invention of Robert L. Shields and is also assigned to the assignee of this application.
  • a motor-driven fan or blower 40 is disposed to introduce secondary air into an elongated manifold 42 suitably supported externally of the chamber and extending along an axis substantially parallel to the longitudinal axis of the chamber. Also the manifold 42 is located preferably near the bottom and at the right side of the chamber as viewed in FIG. 2.
  • the secondary air is injected substantially tangentially into the chamber through a plurality of substantially equally spaced openings 44 in the side wall 28 and at regions located downstream of the region of introduction of the mixture of primary air and waste material.
  • the openings are provided along the entire length of the chamber and are four in number.
  • the tangential injection of the secondary air into the chamber is provided by means of conduits 46 extending between the manifold'42 and the bottom portion of the chamber.
  • means may be provided for preheating the secondary air which is introduced into the chamber 22 through the openings 44 by means of the fan 40, manifold 42 and conduits 46.
  • the combustible waste material is substantially completely burned in suspension in a free vortex with the heavier solid waste fragments and non-combustible material traveling in a vortical path along the inner surface of the layer 34 and migrating toward the end wall 24.
  • the solid material is forced toward the inner surface of the layer 34 by the tangential component of velocity of the vortex whereas the radially inward component of velocity creates high relative velocity between the air and burning material which greatly accelerates the combustion rate.
  • the tangential injection of the secondary air through the openings 44 and at spaced points along the length of the chamber has the beneficial effect of periodically contributing to the vortex energy in the chamber.
  • compensation is provided for losses in vortex energy or for effectively sustaining the vortex as the waste materia] progresses vortically along the length of the chamber.
  • the periodic or spaced tangential injection of secondary air and the resultant sustenance of the vortex along the entire length of the chamber enhances the efficiency of the waste burning process. Also, it reduces any tendency of combustion material particles, such as fly ash, to drop out of the vortex and settle on the bottom of the chamber which, if permitted to occur, can present substantial difficulties in effecting removal of such particles from the chamber and can require longer shut down times for chamber cleaning purposes. Also, it can adversely affect exhaust emissions.
  • adjustable control means are provided between the blower 40 and the manifold 42 and in each of the conduits 46 extending between the manifold 42 and the chamber. More specifically, a damper comprising, for example a butterfly valve 48 is provided in the manifold 42 between the fan and the main portion of the manifold to which the several conduits 46 are connected. The operation of the butterfly valve 48 is determined by the operation of a suitable proportional motor 50 adapted for positioning the valve between open and closed positions in accordance with the degree of energization of the motor. The motor energization is, in turn, determined by a suitable control means generally indicated and designated 52 in FIG. 3.
  • the control means 52 is operatively connected to a thermocouple or other suitable thermally responsive device 54 which extends into the chamber 22 to sense the temperature therein and provide an appropriate control signal.
  • the control means 52 is adapted for automatically operating the damper or valve 48 in response to temperature variations within the chamber and such that the valve is moved toward its most open position in response to increases in temperature thereby to increase the flow of secondary air into the system, and toward its closed position in response to decreases in temperature thereby to decrease the flow of air into the system.
  • the control means 52 is adjustably presettable so that the temperature range over which the valve automatically opens and closes is predeterminable by the operator.
  • the secondary air entering the chamber 22 through the openings 44 is further and individually controllable by means of separate and independently adjustable dampers 56 interposed one in each of the conduits 46.
  • Each damper 56 is adapted for further controlling the secondary air as it enters the chamber at its respective region along the vortical path of the waste material.
  • the dampers 56 are effective for enabling the operator to control separately and individually the energy added to the vortex at each of the regions, permitting more or less energy to be introduced as required to maintain a desired vortical profile and in accordance with experience as to regions where more or less energy is needed to compensate for energy losses in the vortex.
  • each damper comprises a housing 58 of generally rectangular cross section and having suitable flanges for mounting in the respective conduits 46.
  • each damper includes an appropriate flapper element 60 which is pivotally movable about one end thereof between fully open horizontal and fully closed vertical positions illustrated in dash lines in FIG. 6. The pivoting of the element 60 is specifically accomplished by mounting it on a rod 62 suitably rotatably mounted between the side walls of the housing 58. Externally of the housing 58, the rod 60 is bent to provide an operating arm or lever 64.
  • a locking device 66 which can comprise a collar 68 fitted over the rod and fixed to the housing and a set screw 70 threadedly mounted in the collar and carrying a lock nut 72.
  • This arrangement permits the operator of the system to presettably posi tion and lock each of the flapper elements 60 in a desired adjusted position in its respective damper housing for thereby controlling the air entering the chamber at its respective region and for the purpose discussed above.
  • This arrangement is particularly adapted for manual individual adjustment of the dampers 56.
  • each of the dampers 56 could be controlled automatically in a manner similar to the butterfly valve and also that the dampers 56 could be automatically controlled individually or in a cooperating coordinated manner in response to various predetermined parameters such, for example, as secondary air temperature or temperature at different regions in the chamber.
  • first discharge means including a first discharge port or flue 74 having an open end opening in the chamber in the region of the end wall 24 and substantially concentric with the central longitudinal axis of the chamber 22.
  • the flue 74 includes a hollow cylinder or flue pipe 76 of any suitable material extending through and suitably mounted in an opening in the end wall 24.
  • the end wall 24 includes adjacent layers 78 and 80 formed of suitable material such as fire brick, and an outer annular plate 82 secured together by suitable fasteners (not shown).
  • the cylinder 76 is releasably attached to a flue section (not shown) which terminates in an open end opening to atmosphere.
  • Second discharge means is provided for discharging from the chamber 22 during the burning process of non-combustible material.
  • the preferred embodiment provides a second discharge port 84 having an open end 85 opening in the chamber 22 at a region downstream from the point of introduction of the waste material in the region adjacent the inner surface of the end wall 24 and adjacent the inner surface of the layer 34 for receiving and discharging from the chamber non-combustible material which is entrained in the outer region of the vortex.
  • the port 84 comprises a conduit 86 extending through the side wall 28 substantially tangentially thereto and substantially horizontally at the bottom of the chamber as viewed in FIGS. 2 and 3 with its open end 85 opening at the inner surface of the layer 34.
  • the conduit 86 leads to suitable separator and disposal means described hereinafter.
  • the opening 85 is in the path of the non-combustible material which during operation of the incinerator is at the outer region of the vortex and which has migrated to adjacent the end wall 24, and the action of the vortex causes such material to enter the opening 85 for discharge from the chamber 22.
  • the conduit 86 extends horizontally adjacent the bottom of the chamber 22.
  • the discharge opening 85 provided by the conduit 86 is located substantially opposite and in substantially the same horizontal plane as one of the secondary air openings 44.
  • each such conduit or scoop can be arranged to cooperate with an oppositely disposed secondary air inlet to obtain the resultant benefits described above.
  • any non-combustible material will enter the conduit 86 as it initially reaches the end wall 24. However, in the event that such material does not enter the conduit 86 when it initially reaches the end wall 24, this material becomes entrained in the stream of hot gases which normally flows in the direction of the arrows 88 along the inner surface of the end wall24 toward the open end 90 of the flue pipe 76 where a low pressure area exists. If the open end of the flue pipe 76 were flush with the end wall, a considerable portion of this material would enter the flue pipe 76 thus necessitating provision of flue gas cleaning apparatus to avoid pollutionof the surrounding atmosphere. In
  • the flue pipe 76 is extended into the chamber 22 so that the inner open end of the flue pipe 76 is spaced axially inwardly from the end wall 24 as shown in FIG. 3.
  • the solid material which does not enter the conduit 86 tends to move from adjacent the end wall 24 along the outside diameter of the flue pipe 76 toward its open inner end.
  • Such movement increases the time of residence of the material in the chamber 22 thus resulting in more complete combustion and a reduction in the amount of this material which enters the flue pipe as compared to the amount entering the flue pipe if its open end were flush with the end wall 24.
  • a baffle 92 is positioned adjacent the open inner end of the flue pipe 76 to divert outwardly toward the inner layer 34 of the chamber 22 any non-combustible material which moves from adjacent the end wall 24 toward the open end of the flue pipe 76.
  • the arrangement is such that solid material moving in the direction of the arrows 88 engages the baffle 92 and is thereby deflected in the direction of the arrow 94 so that the material so diverted once again becomes entrained in the vortex for further burning and movement toward the end wall 24 for discharge through the conduit 86. As shown in FIG.
  • the baffle 92 preferably comprises a plate of any suitable material in the form of a ring suitably releasably secured to the pipe 76 adjacent its open end. Additionally, this arrangement disposes the inner end of the flue pipe 76 and the baffle 92 adjacent the region of the vortex which can be influenced by the secondary air injected through the opening disposed for cooperation with the discharge port 85. This arrangement together with the adjustability of the secondary air provided by the respective damper 56 affords the operator the opportunity to adjust the secondary air injected at this region in a manner to predeterminedly influence the energy condition of the vortex in the region of the flue pipe opening. Thus, one can adjust to a degree the pressure conditions in the region of the baffle 92 for thereby influencing the flow paths indicated by the arrows 88 and 94.
  • a separator 96 is provided for separating the gases and the solid material discharged through the conduit 86 and for dropping the solid material into a suitable container 98.
  • the separator 96 is preferably a commercially available cyclone or vortex type separator wherein material discharged through the conduit 86 is introduced tangentially into the separator 96 with the result that the solid material drops out the open end of the separator into the container 98.
  • Such solid material constitutes ashes and other particulate matter formed in the combustion process and also non-combustible material which can be disposed of in any suitable manner.
  • the hot gases separated out by the separator 96 are introduced into the flue pipe 76.
