- the ratio of the area of the open end of the discharge flue port to the area of a cross-section of the chamber taken perpendicular to its longitudinal axis is selected to be within the range of one-sixteenth to four twenty-fifth and is preferably one-ninth.
- 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 sidewall 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 movement of the waste material toward one of the end walls and provision is made for igniting the waste material during its vortical movement.
- the pressure of the primary air is selected to be within the range of 4 inches H O to 20 inches H 0, and is preferably about 12 inches H O.
- secondary air is introduced into the chamber at an area downstream from the area of introduction of the waste material, and the pres sure of the secondary air is preferably about 12 inches H O.
- a discharge flue port has an open end opening in the chamber near the one end wall and substantially concentric with the central longitudinal axis of the chamber.
- a second discharge port includes an open end opening in the chamber at an area downstream from the area of introduction of the waste material and adjacent the inner surface of the side wall for discharging from the chamber during the burning process residual combustible material and non-combustible material entrained in the outer region of the vortex.
- the ratio of the area of the open end of the discharge flue port to the area of a cross-section of the chamber taken perpendicular to its longitudinal axis is selected to be within the range of l/ l 6 to 4/25 and is preferably 1/9.
- the combustion chamber is preferably of generally cylindrical configuration and the open end of the discharge flue port is preferably of generally circular configuration.
- the above referred to area .ratios can be translated to corresponding diameter ratios with the result that the ratio of the diameter of the open end of the discharge flue port to the inner diameter of the chamber is selected to be within the range of U4 to 2/5 and is preferably 1/3.
- FIG. 1 is a view in top plan of an incinerator embodying the invention
- FIG. 2 is a schematic diagram of the incinerator of FIG. 1 showing in particular the path of vortical movement of the waste material within the combustion chamber;
- FIG. 3 is a view in side elevation of the combustion chamber and the separator associated therewith with parts of the combustion chamber broken away and shown in section;
- FIG. 4 is a view in section taken along the line 4-4 of FIG. 3.
- FIGS. 1 and 2 an incinerator embodying the invention and comprising in general a size reduction unit for chopping up the waste material, means for introducing the waste material and primary air into a combustion chamber for establishing a vortical movement of the waste material, means for igniting the waste material during its vortical movement, discharge means for discharging gaseous products of combustion, residual combustible material and non-combustible material from the combustion chamber, and a separator for separating the gaseous and solid material discharged by the discharge means.
- 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 shown in FIG. 1 includes a size reduction unit 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 13 into which the waste material is fed for size reduction by a shredding and chopping mechanism (not shown) operated by a motor 14.
- 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 18 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 18 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 FIG. 3.
- 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 (FIGS. 3 and 4) 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 to abrasion 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 fire 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. 1. In certain installations it may be desirable to have the pipe 20 enter the chamber 22 at an area which is substantially midway between the end walls 24 and 26.
- the total pressure of the air exiting from the pipe 20 can beas high as 20 inches H 0 and is preferably about 12 inches H O. However, such pressure can be as low as 4 inches H O when burning finely divided, highly combustible material at a lower heat release rate. Therefore, the present invention contemplates pressures of air exiting from the pipe 20 within the range of 4 inches H O to 2 inches H O.
- a suitable gas burner 38 is disposed near the end wall 26 of the chamber 22 to fire tangentially into the chamber adjacent the bottom and at the right side thereof as viewed in FIG. 1. 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 ordinarily be turned off after ignition of the waste material is accomplished.
- a fan 40 driven by a motor 42 is disposed to introduce secondary air into the chamber 22 preferably near the bottom and at the right side thereof as viewed in FIG. 1.
- the secondary air is injected tangentially to the side wall 28 at an area downstream of the area of introduction of the mixture of primary air and waste material and according to the present invention, the pressure of the secondary air is preferably about 12 inches H O.
- means may be provided for preheating the secondary air which is introduced into the chamber 22 by the fan 40.
- the combustible waste material is substantially completelyburned 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 temperatures are such as to be below the ash fusion temperature so that there is no slagging.
- first discharge means including a first discharge port or flue 44 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 44 includes a hollow cylinder 46 of any suitable material extending through an opening of a casting 48 which forms part of the end wall 24.
- the end wall 24 includes adjacent layers 50 and 52 formed of suitable material such as fire brick, a casting 54, and an outer annular plate 56a 1 secured together by suitable fasteners (not shown) and all surrounding the casting 48.
- An annular plate 57 surrounds the cylinder 46 and is joined to its outer periphery.
- the plate 57 is secured to the casting 48 at its outer surface by suitable fasteners (not shown) and overlaps a portion of the plate 56.
- the plates 56 and 57 are detachably secured together in any suitable manner at their overlapping portions in order to detachably connect the flue 44 and the casting 48 to the end wall 24.
- the cylinder 46 is releasably attached to a flue section 58 shown in FIGS. 1 and 3 which includes a vertically extending portion 58a outside the chamber 22 which terminates in an open end 59 (FIG. 1) opening to atmosphere.
- Second discharge means is provided for discharging from the chamber 22 during the burning process residual combustible material and non-combustible material.
- the preferred embodiment provides a second discharge port 60 having an open end 62 opening in the chamber 22 at an area downstream from the area of introduction of the waste material in the region of the end wall 24 and adjacent the inner surface of the layer 34 for receiving and discharging from the chamber residual combustible material and noncombustible material which are entrained in the outer region of the vortex.
- the port 60 comprises a conduit extending through the side wall 28 tangentially thereto and substantially horizontally at the top of the chamber as viewed in FIG. 4 with its open end 62 opening at the inner surface of the layer 34.
- the conduit 60 leads to suitable separator and disposal means described hereinafter. With the described arrangement the open end 62 of the conduit 60 is in the path of the residual combustible material and the noncombustible material which are at the outer region of the vortex and which have migrated to adjacent the end wall 24, and the action of the vortex causes such material to enter the open end 62 for discharge from the chamber 22. While the conduit 60 is shown in FIG. 4 as extending horizontally at the top of the chamber 22, it is understood that the conduit 60 may be disposed in any angular position about the axis of the chamber 22. For example, in certain installations it may be desirable to position the conduit 60 so that it extends vertically and downwardly.
- conduit 60 may be replaced by a scoop positioned to receive material in the outer region of the vortex and connected to a conduit extending through the end wall 24.
- the flue pipe 46 is extended into the chamber 22 so that the open end of the flue pipe 46 is spaced axially from the end wall 24 as shown in FIG. 3.
- the solid material which does not enter the conduit 60 tends to move from adjacent the end wall 24 along the outside diameter of the flue pipe 46 toward its open 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 66 is positioned adjacent the open end of the flue pipe 46 to divert outwardly toward the inner layer 34 of the chamber 22 any residual solid combustible fragments and non-combustible material which move from adjacent the end wall 24 toward the open end of the flue pipe 46.
- the arrangement is such that solid material moving in the direction of the arrows 64 engages the baffle 66 and is thereby deflected in the direction of the arrow 67 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 60. As shown in FIG.
- the baffle 66 preferably comprises a plate of any suitable material in the form of a ring releasably attached as by bolts 69 to another ring-shaped plate 70 which is welded or otherwise secured to the pipe 46 adjacent its open end.
- the baffle 66 preferably overlies the open end of the flue pipe 46 and includes a central circular orifice 71 having a diameter d (FIG. 3) which is less than the inner diameter of the flue pipe 46.
- the orifice 71 of the baffle 66 thus constitutes the open end of the discharge flue port.
- the outside diameter of the baffle 66 and the diameter d of its orifice 71 are selected to provide optimum performance for the conditions involved.
- the baffle 66 may surround the pipe 46 adjacent its open end in which event the open end of the pipe 46 constitutes the open end of the discharge flue port.
- the detachable mounting of the flue 44 to the end wall 26 as previously described permits detachment of the flue pipe 46 and the baffle 66 from the chamber 22 so as to permit replacement or repair of pipe 46 and baffle 66 as desired.
- a separator 72 is provided for separating the gases and the solid material discharged through the conduit 60 and for dropping the solid material into a suitable container 74.
- the separator 72 is preferably a commercially available cyclone or vortex type separator wherein material discharged through the conduit 60 is introduced tangentially into the separator 72 with the result that the solid material drops out the open end of the separator 72 into the container 74.
- 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. While most of the residual combustible fragments and the non-combustible material are delivered to the separator 72, a small portion of such material settles to the bottom of the chamber 22. This settled material may periodically be removed from the chamber in any suitable manner.
- the hot gases separated out by the separator 72 are introduced back into the chamber 22. This is very advantageous in that it maintains the vortex within the chamber 22, further cleans such gases by removing residual fly ash, and drys out wet waste material within the chamber 22.
- a conduit 76 extends coaxially into the separator 72 at the top thereof so that the hot gases separated by action of the separator 72 are drawn into theconduit 76 through the central low pressure area and are conveyed through the conduit 76 to a fan 7 operated by a motor to withdraw the separated hot gases from the conduit 76 and to introduce such into the chamber 22.
- These gases are preferably introduced into the chamber 22 at an area downstream from the area of introduction of the secondary air.
- the secondary air fan 40 may be employed instead of the fan 78 to introduce the separated gases back into the chamber 22.
- the total pressure available from the primary and secondary air entering the chamber is utilized both to introduce energy into the vortex for obtaining high combustion rates and also to accelerate material out through the conduit 60 and the flue pipe 46. It has been observed that if the area of the orifice 71, which constitutes the open end of the discharge flue port, is too small relative to an optimum area, then combustion rates will be lower than optimum because too much of the available pressure will be used to accelerate the flow of material out of the combustion chamber. On the other hand, if the area of the open end of the discharge flue port is too large relative to the optimum area, it is impossible to establish the vortex flow field required for effecting centrifugal separation of the fly ash and for obtaining substantially complete combustion of larger particles. Tests have demonstrated that the optimum area of the open end of the discharge flue port bears a specific relationship to the area of a cross-section of the combustion chamber 22 taken perpendicular to its longitudinal axis.
- the ratio of the area of the open end of the discharge flue port to the area of a crosssection of the combustion chamber taken perpendicular to its longitudinal axis is selected to be within the range of H16 to 4/25 and is preferably about 1/9.
- these area ratios can be translated to corresponding diameter ratios with the result that the ratio of the diameter d of the open end of the circular discharge flue port to the diameter D of the cylindrical chamber 22 is selected to be within the range of 1/4 to 2/5. This range of diameter ratios has been found to be effective over a range of diameters of the chamber from 1% feet to 15 feet.
- the ratio of the diameter d to the diameter D is selected to be approximately H3 or in other words, the inner diameter D of the chamber 22 is selected to be about three times as great as the diameter d of the open end of the discharge flue port. It is understood of course that the invention is not limited to the particular cylindrical chamber configuration and circular discharge flue configuration illustrated and is applicable in its broader aspects to other configurations of the chamber and discharge flue which are non cylindrical and non circular.
- the nature of the free vortex flow field is influenced strongly by the ratio of the diameter d to the diameter D. With proper dimensions of these diameters selected in accord with the invention, the strong free vortex flow field provides an increasing tangential velocity with decreasing radius. Thus, the tendency of the particles to be drawn'to the center of the chamber 22 by the drag forces imparted from the radially inward flow are counterbalanced by a stronger centrigugal force field. Therefore, the particles are maintained in suspension until complete combustion has occurred or until they are withdrawn from the chamber 22 through the conduit 60.
- a very efficient incinerator characterized by the exhaust of gases to the atmosphere which are substantially free of-particulate matter so as to minimize air and water pollution.
- residual combustible fragments and non-combustible material are discharged from the combustion chamber during the burning process by action of the vortex so as to avoid the provision of costly and complex material handling apparatus for conveying such material away from the combustion chamber.
- the provision of costly and complex flue gas cleaning apparatus is avoided by the invention which allows operation of the incinerator at temperatures which are higher than that which would be allowable in the event flue gas cleaning apparatus were utilized.
- the incinerator effects substantially complete combustion of combustible waste material resulting in an extremely high percentage reduction in the original volume of waste material.
- a typical design of the incinerator of the present invention includes a combustion chamber having an internal length of 8 feet and an inner diameter D of 4 /2 feet.
- the flue pipe 46 has an inner diameter of 2 feet and extends into the chamber a distance of about 16 inches from the inner surface of the end wall 24.
- the baffle plate 66 has a diameter of approximately 35 inches and its orifice 71 has a diameter d of about 1% feet.
- the conduit 60 has an inner diameter of 4 inches.
