Description

STAMPS FOR AN INCINERATOR BACKGROUND OF THE INVENTION John N. Basic, Sr., in his patents of the United States of America Nos. 4,438,705, 4,475,469, 4,516,510, 4,706,578, 5,007,353, 5,209,169, and 5,413,715, science has advanced significantly. of waste incineration, and has shown how to properly control the "three T's" of combustion: viz., time, temperature, and turbulence. In the first and third of these patents, Mr. Basic has disclosed methods and equipment for incineration that have achieved significant improvements in the efficiency of the incineration of different types of waste with optional heat recovery for additional economic use. These two references establish three combustion zones, take temperature measurements in significant locations, and alter the combustion conditions to achieve the desired efficiency and ecological acceptability. In addition, patents achieve their objectives using bulk waste, which simply means that they do not require any process before their introduction into the main chamber. combustion. The system exhibits such flexibility that it can be adjusted to many types of markedly different residues and, nevertheless, achieves its incineration in a manner acceptable to the environment. The principles described in these patents have such a broad applicability that they do not even require the use of waste as fuel. The discoveries find use by combustion of vapors containing hydrocarbons emanating from a generalized and undefined source.

The patents specifically cover the use of the system for such vapors without the presence of a main chamber of the incinerator. Where the main chamber finds use, however, the patents also show improvements for this component of an incinerator system. These improvements include, first, a stepped home floor with air nozzles located on the vertical faces of the steps. As a separate consideration, the combustion chamber of the incinerator receives an approximately stoichiometric amount of oxygen for the burner contents of the chamber, and the floor of the chamber and the volume respectively relate to the heat content of the burning waste. Separately, the air moving into the combustion chamber has an upper limit to its inlet velocity to prevent unwanted waste particles from rising. Alternatively, the various dimensions of the chamber wall are specifically related to one another for improved incineration. In the second and fourth patents listed above, Mr. Basic demonstrated how material seated on a floor is transported, most likely the floor of the home in the main chamber of an incinerator. The patents disclose the sinuous movement of the home or floor that currently pulses the material forward. The movement of the floor closely resembles the activity of shoveling snow or other material. In addition to imparting a general progression of the material, especially burning waste, the pulsation movement accelerates and decelerates and thus also pushes the mass of waste vigorously, increasing the combustion rate and efficiency. The first four patents of Mr. Basic already cited established an entirely new regime for the incineration of waste. These gave the essential conditions for waste incineration and demonstrated how to move bulk waste through the main combustion chamber to facilitate the process. Once these parameters were established, Mr. Basic then applied himself to refining and improving his system. In the process, he increased the sophistication of his incinerator system in an order of magnitude and his ability to reliably handle various waste types, even more than those previously contemplated. The granting of the last three patents already cited above just rewarded his subsequent efforts. In the first of these three patents, Mr. Basic describes several improvements for an incinerator. In these the concept of dividing the reburn tunnel between two sections of reburn, each being able to perform the same functions on the vapors emanating from a source such as the main combustion chamber. The flexibility provided by the two smaller reburn sections dramatically increases control over the three T's of combustion. As a separate aspect, the patent places an "exciter" in the reburn tunnel. The exciter currently reduces the cross-sectional area in the center of the tunnel where the mass flow of gas from the chimney is located and causes the gases from the flume to pass around it. The reduced distance between the gas molecules and a wall, be it the outer wall or exciter wall, and the concomitant reradiation of heat provide dramatically improved control over the three T's. The exciter can also provide nozzles that introduce air into the tunnel to control temperature and time, while also ensuring sufficient oxygen for complete combustion. Other aspects of the exciter include the supply of air through the exciter supports in the reburn tunnel, and ensuring that the exterior of the exciter has a low thermal conductivity to conserve the generated heat. Additionally, the patent has demonstrated that the placement of a damper at the outlet of the reburn tunnel provides even more control over the time (one of the three T's) of combustion. The next patent, No. 5,209,169, covers an entirely new feature located within the combustion chamber that has a hearth floor. Specifically, the combustion chamber can include a grid located adjacent to the entrance door and above the fireplace. This grid will contain wastes that have a high moisture content or a high content of kilocalories (BTU's). In the previous case, the material dries while it is on the grid. In the latter case, some of the volatile hydrocarbons are burned or flushed away to prevent overheating and the possible excorification of the home's floor. In any case, the disposal of the fixed hydrocarbons falls through the grid to the home below, where the complete combustion is carried out. Scrap can do this while it still contains more than half of its combustible hydrocarbons. Alternatively, the grid may have openings of a particular size to achieve the stated objectives. A fluid that passes through the grid, such as air or steam, can serve to cool the grid, and a refractory can serve as additional protection for the grid. When the grid has air passing through it, the gas can then enter directly into the combustion chamber, to enhance the efficiency of the combustion. The movement of the grid can boost its contents to allow the desired burning and stimulate the dry or partially burnt waste to fall through, to the home below. The most recent patent, No. 5,413,715, already listed above, has to do with a ladle to remove ashes from a pond of water after the incinerator has placed them there. The ladle travels along a track and when it reaches the bottom, it is closed so that it can grab the ashes. After traveling up the runway, the bucket opens, and the ashes fall into a receptacle of some kind, such as a truck. As considered from the above, the art and science of waste incineration have progressed significantly under the creativity and tutelage of Mr. Basic. As demonstrated by the recent history mentioned above, each step forward opens up new vistas for further improvements. A number of such advances appear below.

BRIEF DESCRIPTION OF THE INVENTION An incinerator typically has a substantially circumscribed combustion chamber, with an inlet opening for the introduction of the waste, and an outlet opening for the discharge of the combustion products. The combustion chamber also has a floor means for supporting the waste, and a wall means located above the floor means and forming a perimeter substantially closed with the floor means. The wall means, together with the floor means, provides the combustion chamber substantially circumscribed.

As discussed above with respect to Mr. Basic's patent, No. 4,475,469, the incinerator may also include some form of movement means, coupled to the floor means and the wall medium. The moving means moves the floor means along a substantially predetermined path relative to the wall medium. Some incinerators, however, move their "floors" along exact paths. One such system uses a type of "rotary kiln" arrangement. The rotary kiln can have a simple seal with the outer wall since the rotary motion follows an exact path in relation to the wall. The advantages that the Basic system, and especially its pulsed home, have over that type of incinerator have received extensive discussion in several of the patents already referred to above. However, the path by which the moving means moves the floor means can demonstrate substantial deviations from the predetermined desired path, as in the Basic Patent No. 4,475,469. These deviations can be caused by one (or more) of the pulsating bags that is less effective than it should be, or that is less effective than the other bags. Or, the load in the home may lie to one side more than the other. These and other factors may well produce a pulsating current movement that demonstrates substantial aberrations of the norm. Accordingly, deviations from the desired path impose substantial loads on any device incorporated in the incinerator for the purpose of sealing the space between the floor means and the wall means against the passage of gas therebetween.

An improvement for an incinerator then comprises a seal means, coupled to the wall means and the floor means and extending along at least a portion of the closed perimeter. The seal means must substantially prevent the passage of gas between the wall means and the floor means in the part of the enclosed perimeter already mentioned when the means of movement moves the floor means generally along its trajectory in relation to the half wall. The seal means must carry out this task especially when the current trajectory followed by the floor means suffers substantial deviations from its predetermined trajectory. In particular, the seal means may first comprise a retaining means, coupled to one of the floor means and the wall means, to support a substantially fluidized and non-gaseous material. Second, the seal means would then include an immersion device, coupled to the other of the floor means and the wall means, and located, at least in part, in the fluidized material as the floor means moves to throughout its substantially predetermined trajectory. Alternatively, the seal means may comprise a fabric of substantially flexible material, impervious to gas, and heat-resistant, coupled to the floor means and the wall medium. As another possibility, the seal means may incorporate a bearing of compressible material, elastic, substantially impervious to gas, heat-resistant, retained between the floor means and the wall means. As another possibility, the seal means includes a flexible material, impervious to gas, which retains its shape substantially, bound to one of the floor means and the wall means and urged against the other of the floor means and the means of wall to provide a friction seal as the floor medium moves. This material can take the form of a sheet of material that is substantially rigid, but somewhat flexible, such as stainless steel. A very different type of friction seal may consist of a bladder held on one surface and pushed against the other. The bladder, for example, may contain air or some other fluid, or a flexible, resilient, and substantially solid material. As a separate aspect, the floor means may comprise first and second floor sections that meet along a substantially linear path. As before, the floor medium holds the burning debris. A wall means, placed above the floor means, together with the floor means, provides the chamber substantially circumscribed. In this case the movement means is coupled to the first and second floor sections and to the wall means, and moves the first and second floor sections in relation to one another and along substantially predetermined first and second paths, respectively, in relation to the wall medium. Here, the improvement comprises a seal means that engages the first and second floor sections, and extends along at least a portion of the linear path. The seal means substantially prevents the passage of gas between the first and second floor sections in the portion of the linear path when the moving means moves the first and second floor sections in relation to one another. The seal means between the two sections of the floor means can take any of the previously described forms for the interface between the floor means and the wall means described above. In this case, a seal means is related (eg, mated) to one of the first or second floor sections and, in a similar manner, also relates to the other floor section in a manner very similar to that of the floor section. of the seal medium between the floor and the wall medium. The various types of particular seals can be identified as frictional seal, tissue seal, fibrous bearing seal, and fluid seal. The frictional seal, in turn, includes the metal foil seal and the bladder seal. Any or all of these may find use as the means of seal between two moving floor sections. In still more general terms, a system may comprise first and second surfaces that meet along a substantially linear path. A movement means, coupled to the first and second surfaces, moves the first surface along a substantially predetermined path relative to the second surface. An improvement of this system comprises a seal means, coupled to the first and second surfaces and extending along at least a part of the linear path. The seal means must substantially prevent the passage of gas between the first and second surfaces in its portion of the linear path where the first and second surfaces meet when the movement means moves the first surface relative to the second surface generally at along the predetermined path. In detail, the seal means must achieve this when the movement means currently causes substantial deviations in the movement of the two surfaces of its predetermined trajectory. Again, the particular types of seal means described above for the interface between the floor means and the wall medium or between the two floor sections may find use between the first and second surfaces. As before, such seal means is related (eg, mated) with one of the first or second surfaces and with the other surface, as does the seal means between the floor and the wall medium, or between the two sections of a floor medium. Additionally, the seal means, whether between a floor means and a wall, between two sections of floor means, or between two surfaces, can make use of two or more different types of seal means listed above. Such combinations may include a fibrous bearing seal with a fluid seal, a frictional seal, or a tissue seal. A further example may take the form of a fluid seal with a tissue seal, with or without a fibrous bearing seal. Other additional combinations may be advantageous for various situations. A moving home, to provide a complete enclosure around the combustion chamber, will require several sections of seals. Several will have a horizontal orientation. Others will follow a vertical line. A seal between two moving homes, when that happens, also lies along the horizontal. As a result, a complete enclosure can use different types of stamps or combinations of stamps, depending on the needs and the particular requirements of each section of stamps. The use of an incinerator to burn the waste leads to an effort to improve the atmospheric quality in, or around, the unit itself. The incinerator may have a substantially circumscribed combustion chamber, with an inlet for the introduction of the waste and an outlet for the discharge of the combustion products. The chamber may also comprise a floor means for supporting the burning debris, and a wall means, located above the floor means and forming a perimeter substantially closed with the floor means. Together, the wall medium and the floor medium provide the substantially circumscribed chamber. A method for improving atmospheric quality around or inside the incinerator comprises movement of the floor means along a substantially predetermined path relative to the wall medium. The method also has to do with preventing the passage of gas between the wall medium and the floor means along at least a portion of the perimeter when the moving means moves the floor means generally along of the trajectory but with substantial deviations from the trajectory. In detail, the substantial prevention of the passage of gas between the wall means and the floor means may involve the support of a substantially fluidized and non-gaseous material on one of said floor means and said wall means along, for at least, a portion of the perimeter between the floor means and the wall means. An immersion device is attached to the other of the floor means and the wall means along the indicated portion of the perimeter, and located, at least in part, in the material as the floor means moves to throughout its substantially predetermined trajectory. Another option, instead of using an immersion system, is a fabric of substantially flexible material, impermeable to gas and heat-resistant, which can be attached to the floor medium along at least a portion of the perimeter and also to the wall medium, along the specified portion of the perimeter. Or, a resilient, compressible, substantially gas-impermeable and heat-resistant bearing can be retained between the flooring means and the wall medium along at least a portion of the perimeter. Another additional option is the method of ligating a sheet of substantially flexible material, impervious to gas, and retaining its shape, to one of the floor means and the wall means along at least a portion of said material. perimeter; and driving this material against the other of the floor means and the wall medium. As discussed above, the floor means may comprise first and second floor sections that meet along a substantially linear path. The improvement of the atmospheric quality around or inside this type of incinerator comprises first the movement of the first and second floor sections in relation to one another, and along first and second substantially predetermined paths, respectively, in relation to each other. with the wall medium. The passage of gas is substantially prevented between the first and second floor sections along at least a portion of the linear path when the moving means moves the first and second floor sections in relation to one another . Indicated in general terms, the method for improving the atmospheric quality on at least one side of first and second surfaces that meet along a substantially linear path, comprises the movement of the first surface along a substantially predetermined trajectory. in relation to the second surface. The method also comprises the substantial prevention of gas passage between the first surface and the second surface along at least a portion of the substantially linear path when the first surface generally moves along the predetermined path but with substantial deviations from the predetermined path, relative to the second surface. Again, methods for improving atmospheric quality on at least one side of two surfaces of an incinerator having two floor sections can adopt the particular techniques discussed above for an incinerator with a circumscribed main chamber. Instead of an affinity with a wall means and a floor means, the particular methods cited herein will cover either two sections of a flooring medium or two surfaces in general.

The current method used in a specific location can combine two, three, or more of the techniques discussed above depending on the conditions and requirements found and imposed there. In addition, a complete enclosure, such as the chamber of an incinerator, may well use various techniques at different locations on the equipment. This occurs especially where the relevant wall, floor, floor section, or relevant surfaces meet along a non-horizontal line in contrast to a horizontal orientation. Naturally, to seal the joint between two sections of the pulsating floor, such as homes, different methods than those used among other surfaces may be required. Occasionally, the combustion conditions of the incinerator may allow air to enter the main chamber through the space between the floor and the wall. This will allow the use of a positive air pressure to prevent combustion gases escaping out into the surroundings, especially in the event of failure of natural or induced shots. In this case, the incinerator will comprise a combustion chamber substantially circumscribed with an inlet for the introduction of the waste and an outlet for the discharge of the combustion products. Additionally, the chamber will comprise a floor means for holding the burning debris, and a wall means, located above the floor means and forming a perimeter substantially closed with the floor means for, with the floor means, providing a chamber substantially circumscribed. An improved incinerator will comprise (a) a containment means, coupled to the wall means and floor means on the outside of the substantially circumscribed chamber and extending along at least a portion of the perimeter to retain a gas pressure. growing. Specifically, the pressure that can be retained must exceed the pressure (1) within the substantially circumscribed chamber, and (2) on the outside of the substantially circumscribed chamber. The improved incinerator will also comprise a seal means, coupled to the containing medium, which will maintain the gas pressure within the contained medium and in the part of the perimeter in which the contained medium settles, at a higher level than that (1) within the substantially circumscribed chamber, and (2) on the outside of the substantially circumscribed chamber. The increased gas pressure will force air between the main chamber and prevent the combustion gases from passing in the opposite direction into the surroundings of the incinerator. The increased pressure air seal described above may also find use in combination with other types of seals previously mentioned. The presence of the other seals will presently result in a substantial obstruction of, and reduction in, the amount of air entering the combustion chamber through the seal. In fact, the other types of seals can reduce the amount of air thus introduced to minimum or even insignificant levels. c The camera may further include a means of movement, such as the pulsatile mechanism demonstrated in the Basic patent No. U.S. 4,475,469, coupled to the floor medium and the wall medium. The moving means, as before, moves the floor means along a substantially predetermined path relative to the wall medium. In this case, the seal means increases the gas pressure within the containing means and in the perimeter portion when the moving means moves the floor means generally along the predetermined path but with substantial deviations from that path. The improvement of the atmospheric quality around an incinerator can also occur when the combustion chamber can, without excessive deleterious effects, accept the air from the outside of a seal. In this case, the method involves a combustion chamber substantially circumscribed with an inlet for the introduction of the waste and an outlet for the discharge of the combustion products. The chamber itself comprises a floor means for holding the burning debris and a wall medium, located above the floor means and forming a perimeter substantially closed with the floor means, to provide, with the floor means, the chamber substantially circumscribed. The method for improving the atmospheric quality outside the incinerator comprises increasing the gas pressure within a contained medium coupled to the wall means and to the floor means on the outside of the substantially circumscribed chamber and extending along, at least, a part of the perimeter. Specifically, the air pressure in the containing medium must be increased to a level higher than that (1) within the substantially circumscribed chamber and (2) outside of the substantially circumscribed chamber and in the perimeter portion. Naturally, the gas pressure must be maintained at this high level to force the gas between the chamber rather than the other way. Again, many advantages result from the movement of the floor means along a substantially predetermined path relative to the wall medium. However, the gas pressure must be maintained at the rising level in the containing medium when the moving means moves the floor means generally along the path, but with substantial deviations from it.

DETAILED DESCRIPTION FIGURE 1 generally shows at 75 a modern incinerator system employing the two pulsatile homes 76 and 77 and the two stages of heat recovery integrated by the water wall 78 and the boiler 79. To begin the process, solid waste in bulk it enters the hopper 82. From there, the loading ram 83 pushes it inside the combustion chamber indicated generally at 84. In the main combustion chamber 84, the waste falls on the first pulsatile hearth 76 where it is burned with the aid , if necessary, additional heat from the burner 85. The first pulsatile hearth 76 moves the burning residue through its surface and away from the entrance of the main chamber 84 in the manner of the Basic patent, US. No. 4,475,469, discussed above. Eventually, the burning waste falls on the second pulsating hearth 77 where the incineration continues. The blowers 86 and 87 provide the air for the combustion process. While the waste burns, it naturally discharges heat energy. Part of this energy enters the water wall 78 to heat the fluid contained therein. The heated fluid from the water wall of membrane tubes 78 can then travel along the conduit 88 to the boiler 79. The steam removed from the upper part of the boiler 79 can find constructive use elsewhere, either in the incinerator 75 or elsewhere as in the generation of electricity or to provide heat. The waste, after completing its burning, falls from the second pulsating hearth 77 between the ashtray 89, which contains water. The ladle 90, pulled by the cable 91 attached to the engine 92, travels along the track 93. The ladle then discharges the ashes into the hopper 94, and from there they fall between the receptacle 95. The gaseous products of combustion pass through. from the main chamber of the incinerator 84 to the passage 102. There they are joined with the raw waste gases in the hopper 82, which, under the action of the blower 103 travel along the duct 104. This removes, and will serve to destroy, the foul aroma of the raw waste. The gases from passage 102 then enter the first burnout stage 108. There, with the controlled assistance of the auxiliary fuel burner, if necessary, and the air blower 10, they continue to burn at an elevated temperature to destroy minimum fuel elements. in the gas stream. As the incineration of the gaseous products of combustion continues, the gases pass to the second section of burned 1 1 1 where they continue to burn. While this occurs, they receive controlled amounts of additional air from the blower 1 12.

After the second burst stage 11 1, the gases could, if a problem existed in the system, escape through the emergency chimney 1 17. During normal operation, however, the damper 118 keeps chimney 1 17 closed , and the gases travel to the fourth stage of the system 121. There, they receive the addition of gases cooled from the conduit 122. The cooling of the combustion gas stream effected thus lowers its temperature to less than the point where different ingredients in the Gases, such as zinc, can exist in the vapor state. These components thus precipitate outwardly in the cooling process and, consequently, do not condense in the convection tubes of the boiler 79 when the combustion current enters it. As somewhat cooled gases travel through boiler 79, they deliver additional heat for additional useful purposes. As discussed in the first Basic patent, U.S. No. 4,438,705, enumerated above, the first and second burst stages 108 and 11 1 intervene between the water wall 78 and the boiler 79. This allows sufficient heat to remain in the gases during the two burst stages 108 and 11 1 to achieve the complete burning of the fuel elements of the gas stream. After leaving the boiler 79, the gas stream enters the economizer 123. There, the latter preheats the feed water which will be used in the boiler system of the water wall 78 and the boiler 79. Accordingly, the economizer retains additional heat energy from the combustion process and feeds it back into the water that will pass through the system. This preserved heat adds to the steam and electricity generation of the incinerator system 75. From the economizer 123, part of the gas travels along the conduit 124 under the action of the blower 125. This gas, of course, has left much of its content calorific in the boiler 79 and in the economizer 123 and therefore has a lower temperature than it had before entering these latter components. Thus, after traveling along the conduit 122, the gas enters the area of the fourth stage 121 and lowers the temperature of the gas stream passing from the second reburn tunnel 111 as discussed above. The remainder of the gas stream from the economizer 123 passes along the conduit 132 to the heat exchanger 133. The blower 132 passes air from the outside through the exchanger 133 to further cool the gas stream. At this point, the gases have left a substantial part of their heat in the boiler 79 and in the economizer 123. However, the temperature of the gas stream may still remain higher than the vaporization temperature, or the dew point , of the acids contained in it. The heat exchanger 133 reduces the temperature to a point, generally low about 204.44 ° C [400 ° F]. where the acids in the gas stream currently condense to the liquid state. This allows their neutralization, combining them with a base, and their elimination by means of a subsequent treatment, as discussed immediately below. The exhaust gases then receive dry lime and activated carbon along the conduit 135 to neutralize the condensed acids and to remove pollutants, respectively. The gas stream, with these aggregate materials, then enters the baghouse filter and the dry type acid gas scrubber 138, which separates the gas from the particulate matter. Solid matter to receptacle 141 where it awaits removal. The limestone gas from the baghouse 138 travels along the conduit 142. At this point, with current disposal within an operational incinerator, no gas enters the outlet conduit 142 from the conduit 143 because the engine 144 has closed the damper 145 to direct the combustion gases to the baghouse 138. The gases in the conduit 142 are pulled by the draft inducing fan 148, and escape into the atmosphere through the main exhaust stack 149. The continuous emission monitoring system 150 allows the evaluation of the exhaust gases of the various combustion products that may be contained in the exhaust gases 149. These could include particulate matter, carbon compounds, nitrogenous oxides, sulfur emissions, as well as others. The exact task of the monitor system 1 0 depends on the particular case involved, including such factors as the waste being incinerated, the location of the incinerator, and others. During launch operations, incinerator 75 uses natural gas in its burners 85 and 109 to heat it to its operating temperature, when it can begin to receive the current waste. During this warm-up period, the exhaust gas stream contains virtually no components that need to be removed by the baghouse 138. Under these limited conditions, the damper 145 can be fully opened to allow the exhaust gases to bypass the baghouse. [baghouse] 138 and passing through conduit 143 directly to conduit 142 and exhaust chimney 149. However, when incinerator 75 has reached its operating temperature, damper 145 is closed and the exhaust gas stream enters. to the baghouse [138], as described above.

Figure 2 shows the individual pulsatile hearth 158 located within the main combustion chamber 84. The inflatable bag 159, attached to the yoke 160, pushes against the stop 161 to provide pulsatile movement, indicated by the arrow 162 in the various figures, and the vector diagram 163 in Figure 3 as described in the Basic Patent No. US 4,475,469. The blower 165, acting through the conduit 166, provides positive air pressure around the pulsating hearth 158 and between the main combustion chamber 84. Depending on the geometry of the space between the hearth 158 and the walls of the chamber, this pressure of positive air may be sufficient to effectively seal the exterior of the main chamber 84 against the gases contained within it. However, many situations may indicate the desire or even the need for a more positive seal than that offered by positive air pressure alone. For example, positive pressure can introduce unacceptable high air levels in the combustion area. So a physical seal around the pulsating home may be appropriate. Such a seal, to be effective, must accommodate the movement of the home as it moves through its pulsating movement. This becomes particularly important because the movement of the home is not absolutely predictable. Thus, air pockets or other impelling devices do not always produce exactly the same symmetrical movement. In addition, the placement of the waste weight may vary from load to load and may cause substantial deviations in the movement of the household from its standard. As considered in Figures 2 and 3, the isolation of the combustion area from its surroundings will link several different sections of positive seal. The nature and structure of each stamp portion will depend on its location in relation to the home and the types of stamps in use in other positions in the home. So home 158 will have the superior, transverse, horizontal seal 167; lateral, horizontal seals 168; the side, vertical seals 169; and the transverse, horizontal, lower seal, or the end of the ashland 170. Positive seals in these locations may find use in place of, or in addition to, the air seal discussed immediately above. In addition, the following discussion often focuses on an individual section of the positive seal in an incinerator. Naturally, all the sections will generally be connected to one another and will form a closed perimeter to reach the gaseous insulation inside the combustion chamber against the outside. Also, the following discussion may refer to a particular structure that finds use in a stamp location. Often, with very little or no modification, the same structure may very well find use elsewhere in the home. In such cases, observations about the seal in one of the locations generally apply equally, in general, to its other facilities. One type of positive seal, seen in Figures 4 to 19, involves ligating a piece of elastic metal, such as elastic steel sheet, to the pulsating hearth 158 or to the outer wall. The same piece of metal is pushed against the other surface to create a sliding friction seal. An elemental seal of this type generally appears at 173 in Figures 4 and 5. There, the stainless steel and corrosion resistant 174 steel sheet has generally assumed a "Z." In Figure 5, the first leg 175 of the "Z" shaped metal strip 174 is firmly attached to the wall structure indicated diagrammatically at 176. The central section 177 of the "Z" extends between the surface of the the wall 176 and the hearth 158. Finally, the last section 178 forms the curve 179 which currently rests against the home 158 itself. As the hearth 158 moves through its pulsating movement, the curve 179 on the metal strip 174 slides along the hearth. The strip 174 is configured and is attached to the wall 176 such that the curve 179 is continuously driven against the hearth 158. A lubricant such as molybdenum disulphide grease or dry type aerosol lubricant helps reduce wear on the curve 179 and in the home caused by the sliding of the one along the side of the other. Accordingly, due to the drive resulting from the elasticity of the metal strip 174, the curve 179 remains in contact with the hearth 158 as it moves through its range of motion. Of equal importance, the home 158 may, due to the factors listed above, have a component of slight movement from side to side, or lateral, as the latter experiences its pulsatile movement. That is, home 158 may move slightly toward and away from the surface of wall 176 as it is pressed. However, the elasticity of the steel strip 174 accommodates this movement, and the curve of the strip 179 remains in contact with the hearth through its range of motion to provide a continuous positive seal. As indicated above, the seal 173 provided by the steel strip 174 acts in two ways. First, the seal restricts, minimizes, and possibly prevents the combustion gases on the hearth 158 from entering the outer surroundings of the incinerator. This, of course, is important because gases in the main combustion chamber can be particularly unhealthy for workers or others present near the incinerator. This is especially the case when the incinerator is located inside an enclosed room, as is frequently the case. Second, seal 173 restricts the passage of outside air between the incinerator. As the John Basic patents listed above clearly state, achieving complete burning of the wastes, and in a way acceptable to the environment, it includes strict control of all incineration factors in the main chamber, as well as in the tunnels of burned This includes, in particular, the amount of air introduced between the main chamber; the places where air enters the chamber; and the temperature of the air introduced as well. Seal 173 serves to minimize the air entering around the side of the home and to prevent the quality of the incineration that occurs in it from being affected deleteriously. This aspect of seal 173 and the other seal varieties discussed below is important because the main combustion chamber (as well as the reburn tunnels) must function, and usually does, under a negative pressure compared to the surrounding environment. This negative pressure can result from a natural shot that accompanies burning, or from an induced shot when it is present. Either or both of these sources of draft (i.e., negative pressure in the main combustion chamber) ensure the passage of the combustion gases in the proper direction towards the chimney. This shot would attract air from the surroundings of the home without the intervention of the seals discussed here and may affect the combustion conditions deleteriously. On the other hand, a positive partial pressure may from time to time develop within the combustion chamber. This may result due to the lack of any natural draft and the draft inductor fan. In addition, a rapid "bloom" or incineration of highly volatile materials in the waste can cause a substantial increase in the pressure in the main chamber. However, the positive seals discussed here can help prevent gases inside the main chamber from escaping to the outside where they can potentially cause substantial damage. Figure 6 demonstrates a modification of the lateral, horizontal friction seal, in which the nut and bolt pair 184 holds the metal strip seal 185 against the wall 176. The strip 185 comes into contact with the hearth 158 again for seal against the gas passage. In Figure 6, however, the tension spring 187 is stretched between the strip 185 and the floor 188. The force of the tension spring 187 pulls the strip 185 down to ensure its firm contact with the hearth 158 as it is. The home moves through its pulsating movement. Naturally, the construction of the incinerator must usually allow access to the spring 187 and its connective cable 188 for occasional maintenance or replacement. Figure 7 shows a slight modification in the arrangement of Figure 6. Here, the strip 192, anchored by the bolt 193, takes an angular direction downward while extending toward the hearth 158. This allows the compression spring 194 push it up to make firm contact with the hearth 158. Figure 8 demonstrates another modification in which the bolt 195 holds the strip 196 anchored to the hearth 158 itself. Strip 196, in turn, slides against wall 176 to provide the frictional seal. Here, the tension spring 197 holds the strip firmly against the wall 176 to provide a secure seal. As with the other friction seals, a lubricant should be used to prevent excessive wear of the elastic metal strip. In addition, the construction of the incinerator must facilitate access to allow the maintenance of the various components of the seal. Additionally, the spring should desirably settle on the seal side away from the incinerator fire. This, clearly, serves to protect against the destructive influence of the burning environment. Figure 9 demonstrates the elastic metal strip 201 used as the upper horizontal friction seal at the end of the magazine. The bolt 202 holds the strip 201 against the end wall of the carburizer in the incinerator 203 where it rests against the shelf 204 attached to the hearth 158. The tension spring 205 pulls the strip 201 until it makes firm contact with the shelf 204 to secure a reliable seal. The shelf 204 will have a location in the home 1 8 in line with the strips 165 of Figure 6, 192 (of Figure 7), or 196 (of Figure 8) to provide a continuous seal around the corners of the front end of the home. This alignment appears schematically in Figures 3. Similarly, Figure 10 has a lower, horizontal friction seal at the end of the ash, which makes use of the elastic metal strip 208 in frictional contact with the bottom of the hearth 158. The bolt 209 links the strip 208 to the bottom surface 210, and the tension spring 21 1 secures the sealing contact of the strip 208 with the hearth 158. Figure 11 demonstrates the use of the metal strip 215 as a vertical seal and lateral near the end of the ash 216 of the hearth 158. Again, the strip 215 has a frictional contact and sealant along the line 217 with the hearth 158. The top 218 of the line 217 is connected with the horizontal side seals 185, 192, and 196 of Figures 6, 7, and 8 respectively. The bottom of the seal line connects upwardly with the horizontal bottom seal at the end of the ashpit 208 of Figure 10 to provide, again, a closed perimeter. Further details of a vertical, frictional, and sliding seal appear in Figures 12 to 14. There the elastic sheet metal strip 223 has the short leg 224 which slides against the side of the hearth 225. The bolts 228 join the strip 223 to support 229 supported by bolts 230 to post 231. Support 229 holds strip 223 against home side 225. Figure 15 shows home 225 moving to the right as indicated by movement arrow 162. The strip seal 236, in contact with the hearth, is held to the post 237 together with the support 238, by the bolt 239. The tension spring 240 connects to the blade 241, which is attached to the pole 242. The other end of the spring 240 engages the loop 243 attached to the metal strip 236. The tension of the spring 240 keeps the strip 236 in firm contact and thus forming a sealant relationship with the home 225 as the hearth travels through its movement Pulsed 162. The sliding seal of strip 236 in Figure 16 differs from that in Figure 1 only by having the compression spring 245 that urges it against the home 225. In turn, the bolt 246 anchors the spring 245 against the outer wall 247. The drawings of the Figures 15 and 16 represent views taken from above and looking down on vertical, sliding seals. The same drawings may well represent the lower transverse seals with the view taken from the side. The same general construction works for both cases.

Figure 17 demonstrates a modified structure for flexible elastic steel strip 251 which is used as the sliding friction seal. There, the strip 251 assumes a somewhat sigmoidal configuration which allows it to make contact with the home in its upper curve 252 and a contact with the stationary structure 253 in its lower curve. Bolt 255 anchors strip 251 to angle bracket 255, which is attached to the shelf. Finally, the bolt 258 joins the shelf 257, and thus the strip 251, to the stationary structure 253.

As suggested above, the curved configuration of the strip 251 allows it to provide, in effect, two sliding friction seals. The first seal occurs in the uppermost curved portion 252 where the strip 251 comes into contact with the hearth 158. The second seal occurs in the lowermost curved portion 254 where the strip 251 slides along the stationary structure 253. Thus that the combustion gases settle in the area 259 where they can not affect the external area 260 away from the combustion fire or the remaining structure of the strip seal itself. In addition, tightening the strip 251 between the home and the stationary structure 253 helps ensure a tight and secure seal. Specifically, the strip of elastic steel metal 251, with its curved structure, must be tightened or flattened to fit in the space between the hearth 158 and the structure of the base 253. When it is finally placed on this site, the elasticity of the steel seeks to undo the predicament that allowed its placement on this site. This tendency of the steel strip 251 to return to its previous configuration results in the strip pressing against the hearth 158 and the base 253 to provide the two seals mentioned above. As always, in the case of a sliding or friction seal, a dry lubricant, typically molybdenum disulfide, at the contact points of the seal with the structures, will extend seal life and reduce the required maintenance. Additional protection for strip seal 174 is shown in Figure 18. Nozzle 264 sprays coolant 265 over strip seal 174 to cool its various sections 175, 177, 178, and 179. Fluid 265 can take the form of a liquid, such as water, or a gas, such as air. In any event, the fluid protects the metal seal 174 against the heat of the furnace that occurs in the area 267 between the hearth 158 and the external wall 176. A large amount of excessive heat could simply destroy the seal 174 and allow undesired effects. discussed above. The heat could happen if the shot in the incinerator were to get lost and the flame tried to move externally out of the combustion chamber. But, even if this did not happen, if the strip were to be heated to a temperature even below the temperature of its destruction, the metal in the seal could lose its elasticity and thus its ability to remain in contact with the hearth 158 and block the passage of the gas between or outside the furnace area 267. The nozzle 164 receives its cooling fluid from the conduit 270 through the control valve 171. The valve 271 can be operated simply manually, with the operator turning it on or off depending on the operation of the incinerator. When the valve is turned on, it provides a constant stream of coolant during the time the incinerator is in use. Alternatively, the valve 271 can operate mechanically under the control of the radiant-type temperature sensor 272. When the sensor 272 determines that the temperature of the seal 174 has risen to a predetermined level, it causes the valve 271 to turn on to cool the valve. seal 174. If not, valve 271 can be kept closed. Alternatively, the valve can simply open and close intermittently as, for example, when the hearth 152 currently pulsates. In any event, the nozzle fluid may also establish an air knife outside the pulsating hearth 158 to provide a barrier to maintain the combustion gases on the fire side 267 of the incinerator and the air outside. In Figure 19, the source of the cooling fluid takes the form of the plenum 273 which receives the air under pressure from the blower 274. The air under pressure leaves the plenum 273 through the line of nozzles 276 arranged along the surface of the hearth 158 to cool the metal strip 278. The blower 274 can operate continuously or be subjected to the control of the temperature sensor 279 similar to the mechanism shown in Figure 18. Or, the blower can simply provide the air intermittently. The air in the nozzle array 276 also acts as an air knife similar to that in Figure 18. This helps prevent the flow of the gases to, or from, the side of the furnace 267 between the mechanical seal 278 covered here and the pulsed hearth 158. Figure 20 demonstrates the replaceable sliding metal seal indicated generally at 284 attached to the projection of the wall 285. The nut 286 is screwed to the bolt 287 to hold the seal 284 in place. During operation, the corner 288 of the seal 284 contacts, and slides along, the vertical metal plate 289 attached to the hearth 158 to provide the frictional seal.

As shown in the drawing, the ash 290 can accumulate on the side of the seal 284 furnace. When this occurs, the operator, with access to the components, can simply pull the elastic metal strip 284 downward to let the ashes 290 fall through to the floor. In addition, if the seal strip 284 were to suffer some damage caused by heat, corrosion, or other similar causes, the operator can simply unscrew the nut 286, remove the strip 284, and replace it with another. In Figure 21, the inflatable bag seal indicated generally at 295 acts as a horizontal, frictional, and transverse transverse seal between hearth 158 and wall 296. Anchored to shelf 297, bag 298 itself may contain air, gas, or some other fluid. The bag 298 slides along the wall 296 as the hearth 158 moves. The inflated bag 298 must have sufficient sponginess or elasticity to accommodate the vertical component of the movement of the home as well as its horizontal component. It must also have some lubricant at its point of contact 298 with the wall 296. The surface of the bag 295 may be self-lubricating, or may require the application of some external lubricant as discussed above. Naturally, the material of the 295 bag must prove to be resistant to fire or high temperatures, for obvious reasons. Alternatively, the bag 296 may be attached to the wall and slide along the shelf 297. The type of bag shown in this figure and in the following figure 22 may find use for any of the seals in the incinerator, including those shown in the drawings. Figures 2 and 3, and also as a transverse seal between multiple moving homes. The bag indicated generally at 301 in Figure 22, instead of being inflated only, is filled with some solid material 302. This could include sand or solid type materials such as pebbles, silica and alumina that also exhibit fire resistance. The material 302 should provide sufficient flexibility and resilience in the bag 301 to allow it to deform sufficiently as the hearth 158 moves toward the shelf 297 and yet later return to its original shape when the two structures move away from one another. to the other. With this exception, the observations for the bag seal 295 in Figure 21 apply to the filled bag seal 301 of Figure 22. Figures 23 and 24 demonstrate a transverse, lower, horizontal bladder seal at the end of the zander , generally at 304 which is rubbed along the bottom 305 of the hearth 158. The seal 304 includes the rubber tubing 307 attached by the bolt 308 to the adjustable bracket 309. The adjustable ledge 309, in turn, sits on the immobile shelf 310, attached by bolts 31 1 to underlying support structure 312. Adjustment nuts 315, twisted on threaded rod 316 attached to shelf 309, allow adjustment of the height of bladder 307. Loose seal generally shown at 320 appears in Figures 25 and 26. There, the pins 321 support the fabric 322 of flexible fire-resistant material, to the hearth 158 and to the outer wall 323. The fabric of material 322, of course, must have sufficient flexib It is necessary to accommodate the pulsed movement of the hearth 158 indicated by the arrow 162. As seen in detail in the vector diagram 163 of Figure 3, this movement includes, first of all, a component of reciprocating horizontal movement. Typically, the fabric 322 has no difficulty in accommodating the horizontal movement component. However, home 158 also has an upward movement component. This vertical component imposes significant stresses on the fabric 322 as the home experiences its pulsed movement. Clearly, the fabric 322 must have sufficient elasticity and flexibility to accommodate the two movement components. The fabric 322 can very well wrinkle while the hearth 158 moves with its pulsed movement. Nevertheless, the fabric must have enough material to prevent it from collapsing, which can deleteriously affect its ability to provide its sealing function. Figures 27 to 31 provide diagrams for various types of water seals discussed in greater detail in the subsequent drawings. Accordingly, Figure 27, particularly, shows a lateral, horizontal water seal, generally at 327. There, the water channel 328 is affixed to the outer wall 330. The knife blade 331, or metal strip, is affixed to, or is formed of, the same piece of metal used for the cross piece 332 which in turn is connected, in an airtight relationship with the fluid, to the hearth 158. The knife blade 331 in the water 329 provides a barrier fluid between the side of the furnace 333 and the external environment 334. As seen in the figure, the water channel 328 329 easily accommodates the horizontal movement of the hearth 158 within and out of the plane of the paper. However, the depth of the channel 328 also maintains the seal during the vertical movement of the hearth 158, which can generally rise 10.16 cm [4 inches] during its pulsed movement. Figure 28 demonstrates the transverse, horizontal, and upper water seal at the end of the loader, generally at 340. There, the shelf 341, attached to the hearth 158, holds the blade 342 in the water 343. The channel 344 holds the water 343 and joins the fixed surface 345. The channel 344 should not move with the hearth 158 since that would cause the water 343 to overflow as the hearth 158 moves by means of its pulsed movement. In addition, the blade 342 is inclined in the direction of movement of the hearth as indicated by the arrow 162. This helps prevent the blade 342 from drawing water 343 out of the channel 344 as the hearth 1 8 moves to the left as as seen in Figure 28. Again, the seal 340 provides a barrier between the furnace side 347 of the main combustion chamber and the exterior 348. The transverse, lower, horizontal water seal at the end of the ash, generally appears at 350 in Figure 29. The blade 351 is attached to the bottom of the hearth 158 and sits on the water 352 supported by the channel 353. As in the previous figures, the channel 353 is affixed to the stationary surface 354 so that the 352 water does not spill out as home 158 shakes with its pulsed movement. In addition, the blade 351 is tilted in the direction of movement indicated by the arrow 162 to prevent the water 352 from spilling out during the movement of the hearth toward the left in the figure. Figures 30 and 31 show the somewhat rare vertical and lateral water seal generally at 360. The difficulty with a vertical water seal is due to its orientation. All horizontal seals use a blade submerged in an open, horizontal channel. Obviously, that does not work for a vertical seal; An open vertical channel would simply allow the required water to spill out of the channel. Accordingly, Figures 30 and 31 demonstrate an arrangement that will achieve vertical vertical water seal. There, the water container 361 is formed of the three vertical sides 362, 363, and 364 and the bottom 365. The two outer sides 362 and 364 have the lips 366 and 368, respectively, and the bottom 365 has a lip as well. The sides 362 and 364, the bottom 365, and the lips 366 and 368, as well as the bottom lip 365, are composed of a somewhat flexible, elastic, and heat-resistant material, such as a suitable rubber. The external compression spring 373, anchored to the outer wall 374, urges the water container 361 against the pulsed hearth 158. This impulse, together with the flexibility of the sides 362 and 364, the bottom 365, and its associated lips results in that the sides, the bottom, and the lips act as cleaning sheets against the home 1 8 and minimizing the passage, and thus the loss, of water between the container 361 along the wall of the hearth. In addition, as the hearth 158 moves along its pulsed direction 162, the sides, bottom and lips function as cleaning sheets that travel through the surface of the hearth, again reducing the loss of water to a minimum. . However, in all likelihood, some water will escape from the container 361 especially during the movement of the home 158. To compensate for this loss, the supply line 375 connects the container 361 with the reservoir 376. The water from the reservoir 376 replaces any water that would have escaped out of container 361. Typically, a float or other device then makes sure that the water in reservoir 376 remains at the level necessary to replace any water lost from container 361. As discussed above for other types of seals, a complete seal around the home 158 generally requires an enclosed perimeter of seal sections such as those shown in Figures 27 to 31. Accordingly, the main chamber of an incinerator with a single pulsating hearth 158, so that it has a perimeter closed water seals, will have a lateral, horizontal seal 327 (of Figure 27) on each side; an upper, transverse, horizontal seal on the side of the charger 340 (of Figure 28) at the end of the hearth charger 158; a transverse, horizontal, lower seal at the end of the ash 350 (of Figure 29); and a lateral, vertical seal 360 (of Figures 30 and 31) on each side of the hearth between the upper, lateral, horizontal seal 327 on each side; and the lower transverse seal 350. Furthermore, to avoid leaks in the seam of two seals, the water for them, if at the same level for both, should form a continuous pool as shown below with reference to Figures 50 to 53. Seals that can take advantage of a continuous pool of water include the horizontal side seals 327 and the upper seal, horizontal, at the end of the loader 340. Theoretically, it could also incorporate the side seals, vertical 360, although the last drip problems could infect the other stamps. The above discussion seems to suggest the use of water seals (or any kind of seal) for all sections of a perimeter around the home. Thus, Figures 27 to 31 provide a water seal for all sections of the complete seal of the home. However, that is not necessarily the case. Particularly, as discussed above, the vertical water seal 360 shown in Figures 30 and 31 has intrinsically a greater likelihood of having leaks. Thus, the current construction of an incinerator can use a water seal (or other kind of fluid) for all sections with the exception of the vertical seal. This last seal may take the form of a rubbing, rubbing seal, discussed above. This seal, in whatever form, must then make tight contact with the transverse water seals, lateral, horizontal, and inferior, where it meets with the others. Typically, containers 328, 344, and 353, as well as the water channel discussed below, will have a stainless steel composition to prevent corrosion caused by the combustion gases of the incinerator. This also applies to blades 331, 342 and 351 and also to those in the following discussion. In particular, the combustion gases may contain chlorine, a component of many plastics, for example. Chlorine, when dissolved in water, produces hydrochloric acid. Stainless steel helps avoid the corrosive effect of acid. To provide additional protection, the water may contain an added base to neutralize the acid. If the combustion gases come to produce a base when they are dissolved, then the water in the channels may include a neutralizing acid. Water 329, 343, and 352 on channels 328, 344, and 353, respectively, provide another important advantage. Specifically, the water cools the blades 331, 342 and 351. These blades, during the operation of the incinerator, are exposed directly or indirectly to the hot gases of the incineration. This high temperature environment could destroy the blades. The water cools the blades and helps to avoid this destructive effect. The same observations apply to the blades that are used for the water seals below. Other characteristics of particular seals, such as heat-resistant fibrous bearings, can reduce this problem. Hor, water avoids high temperatures that could damage or destroy stainless steel blades.

Figure 32 and, in greater detail, Figure 33 demonstrate a transverse, horizontal lower seal at the end of the ash, usually at 379. A brief comparison of these drawings shows that they closely resemble the installation of the bladder seal of Figures 23 and 24. In the present case, however, the adjustable shelf 309 supports the water channel 380 which fits in the cutout 382 of the support 312. The bottom of the channel 380 includes the drain 385 with a stopper to allow the removal of water 381. The settling rod 386 then joins the gas-tight flexible fabric 387 to the lower face 305 of the hearth 158 in a gas-impermeable manner. The fabric 387 can take the form of a combination of Kevlar® and Nomex® aramid fabric, 1/8 inch [0.3175 cm] in thickness, manufactured by the DuPont Company of Wilmington, Delaware, or the equivalent. Various bags such as rayon, glass fiber, Goretex, and others, especially those with low micron meshes, may be sufficient. Other thicknesses, more or less than those listed above, can also be effective. The lower portion of the fabric 387 then sits in the water 381 to provide a gas seal between the side of the oven 388 and the exterior 389. The pure bottom of the fabric 387 is wrapped around the weight of the pole 390 to hold it in the water 381. As before, the lower and horizontal transverse seal 379 must align with the vertical and lateral seal 391 in whatever form the latter will take.

The seal generally at 394 of Figure 34 closely resembles tissue water seal 379 of the previous figure. However, in this case, the seal uses the rigid blade 395 of stainless steel sheet immersed in the water 381 to provide the seal. The bar 386 keeps the blade 395 in place (without the aid of a component comparable to the weight bar 390). Figures 35 and 36 demonstrate diagrammatically the upper, horizontal, transverse water seals at the end of the ash, at 401 and 402, respectively, similar to the lower seals at the end of the ash of Figures 33 and 34. Both make use of the stationary channel 403 attached to the structure 404 holding the water 405. The cover of the channel 408 provides a side of the barrier between the gas area of the furnace 409 and the exterior 410. This also allows access to the channel 403 for cleaning. The cover 408 is affixed to the stationary structure 412. In Figure 35, the support plate 413 is affixed to the stopping staple 414 coupled to the hearth 158. In turn, the setter bar 417 couples the flexible fabric 418 of material, similar to that in Figure 33, to the support plate 413. The weight of the rod 419 holds the fabric 418 in the water 405. In Figure 36, the stainless steel plate 422 takes the place of the fabric 418 of the previous figure and is supported to the support plate 413 by the bar 417. As with other steel plates used as a transverse seal at the end of the magazine or at the end of the ash, the plate 422 must form a relatively small angle relative to the horizontal. This will help prevent the plate 422 from pushing the water 405 out of the channel 403 as the hearth 158 moves by means of its pulsed movement 162. The fabric 418, as is typical of tissue water seals, seems to displace less water during the pulsation of the home that water seals with rigid blades. Figures 37 and 38 show an installation of a transverse and horizontal water seal, at the end of the loader, generally at 425 and 426, respectively. In both, support structure 427 holds the channel 428 in a stationary position so that water 429 remains inside. The pulsating hearth 158 has the support plate 430 attached thereto by the staple 431. The bolt 434 holds the stopping strip 435 and, in Figure 37, the stainless steel blade 436 to the support plate 430. The blade 436 in the water 429 provides the seal between the furnace side 437 and the exterior 438. The seal 425 must be aligned, and connected, with the side and horizontal seal indicated by the horizontal line 439. This relationship is discussed below, with respect to Figures 50 to 53. The seal cover plate 440 rotates around the hinge 441 to allow access to water 429. In Figure 38, pin 434 and retaining strip 435 are tightened firmly on flexible and fire-resistant strip 442, held in the water 429 by weight rod 443. Strip 442 in water 429 provides the seal between furnace environment 437 and exterior 438. Otherwise, the above observations with respect to Figure 37 apply here.

Figures 39 and 40 generally show the lower, horizontal, transverse seals of the end of the ash at 447 and 448, respectively, which are almost identical to the water seal 394 of Figure 34. However, seals 447 and 448 they find use in the situation where the kiln gas, located at 451, can react deleteriously with water 381 at seal 394. Such a situation, for example, can occur where the waste contains a substantial number of disposable baby diapers, for example . The absorbent polymer gel in these diapers vaporizes and can solidify when dissolved in water 381, forming a colloidal gel with water. This would clearly interfere with the concept and operation of a "fluid seal" mentioned above. Therefore, instead of using water as the sealing means, channel 380 of Figure 39 uses sand 452 to provide the seal. Similarly, Figure 40 demonstrates the bubbling medium 453 as the fluid. In the latter case, the bubbles may be constituted by pebbles or particles of alumina or silica. The fluid media 452 of Figure 39 and 453 of Figure 40 sit on the fine mesh screen 456 welded to the channel 380. The air tubes 457 lie above the channel 380 and below the screen 456. The tubes 457 provide air at the space 458 between the sieve 456 and the bottom of the channel 380. The air then passes upwardly through the sieve 456 to help fluidize the means 452 and 453. The tubes 457 may or may not provide the air continuously or intermittently, depending on the nature of the waste that is being incinerated. In fact, Figures 62 and 64 demonstrate the use of such means without passing air or any other gas through them. However, when the tubes 457 supply the air intermittently, they can do so in a synchronized relationship with the pulsation of the hearth 158. Thus, they can operate for a period beginning moments before the pulse and ending just after. This would be particularly useful because the household pulse can currently cause a slight increase in internal gas pressure in the main combustion chamber. The reduction or possible loss of the desired draft during this particular period suggests using the 457 air tubes during this period. When the pipes 457 provide air in the channel 380, they provide a flow of fluid outside the hearth 158. This can act as an air knife to help prevent the escape of combustion gases from the kiln area 451 similar to the fluid streams of Figures 18 and 19. Figures 41 and 42 similarly demonstrate the stamps generally at 461 and 462, respectively, which closely resemble seal 402 of Figure 36. Here, the fine mesh screen 463 is welded to the channel and covers the tubes 464. The tubes 464, alternatively, introduce air or gas into the space 466 underlying the screen 463. The sand 467 sits on the screen 463 in Figure 41, and the bubble material 468 fills the space in Figure 42. In either case, the steel blade 422 remains in the sand 467 or in the bubble material 468 to provide the seal. As in Figures 39 and 40, the tubes may or may not introduce gas between the space continuously or intermittently, depending on the circumstances, to further fluidize the means 467 or 468. As in Figure 36, the seals 461 and 462 they typically fall on line 410 of, and connect to, the side horizontal seals. An incinerator, as shown in Figure 1, can have a multiplicity of the two homes 76 and 77 or even more. To enclose the interior of the main chamber completely, a seal is also required between each of the two homes that adjoin one another. This type of seal between two adjacent homes must actually work under more stringent conditions: first, both households experience the pulsation; second, the rate of repetition of pulsation generally varies for the two households, with the lower household generally pulsating less frequently than the superior household; and thirdly, the two households may suffer different somewhat irregular trajectories of their respective norms. A water seal between two households currently combines a lower, horizontal seal at the end of the heifer in the upper hearth, with an upper, horizontal seal at the end of the hearth of the lower hearth. Each of these seals extends a blade into a water channel attached to a stationary object. These intermediate water seals are discussed below with respect to Figures 43 through 48 and 57. Alternatively, the seal between two homes may take a certain form of the seals shown above with the exception of a water seal. The same observations would apply to these various seals between households. Figure 43 and, in greater detail, Figure 44, show the two homes 158a and 158b that work in tandem. They pulse generally in the directions 162a and 162b, although the frequency and pulse forces for the homes 158a and 158b typically vary from each other. This situation may well be agreed with the twin homes 76 and 77 of Figure 1. Or, this may occur when the main chamber of the incinerator has three or more homes, as in Figure 57 below. In actuality, the intermediate, horizontal transverse seal, usually in 475, can find use between any two pulsatile homes. As seen in Figures 43 and 44, seal 475 combines, not surprisingly, a seal of the type of the horizontal, lower end of the ash, indicated generally at 476, with a top, horizontal seal of the end of the loader, generally shown at 477. The previous seal type appears in Figure 34, while Figure 37 demonstrates the last type of seal. In Figure 43, the upper hearth 158a has the joined blade 478 in the water 479, which is held in the channel 480 attached to the stationary surface 481. Similarly, the lower hearth 158b has the joined blade 485 also seated in the water 479. Water 479 with the two submerged blades 478 and 485 provides the seal between the environment of the furnace 486 and the exterior 487. For the upper hearth 158a, the seal provided by the blade 478 is aligned with the location of the vertical and lateral seal , shown by dashed line 488. Similarly, for lower hearth 158b, seal 477 of blade 485 is aligned with the upper and side horizontal seal of the hearth indicated by dotted line 489. And, both blades 478 and 485 lie in the same horizontal plane as established by the seal line 489. The relative locations of these stamps provide a closed perimeter and thus a continuous seal through the two hearths is pulsatile 158a and 158b. Figure 44 shows in detail that the water channel 480 sits on the stationary structure 481 and makes no contact with the upper hearth 158a or the lower hearth 158b. This prevents the movement of households from causing water 479 to overflow from the canal.480. Figure 45 demonstrates the transverse, intermediate, and horizontal seal generally at 490 between the two hearths 158a and 158b, which is virtually identical to seal 475 of the previous figure. Again, the channel 491 sits on the stationary surface 492 and holds the water 493. The blades 494 and 495 of the upper hearth and lower place 158a and 158b, respectively, settle in the water 493 to provide a water seal. However, Figure 45 also includes the additional seal 496 formed by the compressible, elastic, and fibrous bearing 497 between the homes 158a and 158b. The alloy forks 498 anchor the bearing 497 to the steel plate 499 that covers the refractory 500 of the lower hearth 158b. In turn, the fibrous bearing 497 pushes and rubs against the steel plate 502 at the bottom of the refractory 503 of the upper hearth 158a, as either or both homes experience their pulsed movements. However, the forks 498 should not have a length that brings them in contact with the steel plate 502 of the upper hearth 158a when the movement of the hearths 158a and 1 8b brings them to their minimum separation to each other. Again, a high temperature lubricant, generally a molybdenum disulfide, between the bearing 497 and the upper hearth 158a, facilitates the movement of the former against the latter. The lubricant is typically sprayed on the bearing 497 and the steel plate 502. The bearing 497 has a symbiotic relationship with the lubricant protecting it against the heat of the combustion fire in the main chamber 504. The bearing 497 must have a composition resistant to high temperatures and gases generated in the environment of the incinerator 504. The fibrous bearing 497 must exhibit sufficient compressibility and elasticity to fill the space 505 between the homes 158a and 158b as their respective movements 162a and 162b cause that space to increase or decrease. decrease. Bearings integrated by alumina oxide-matured fibers, silicon oxide, or a mixture of the two in combination should work for this purpose. Bearing 497 generally and largely serves to isolate water 493 from the hot, caustic, and possibly harmful atmosphere of gas 404 of incinerator 504, which, in particular, could damage seal 485. That is, the bearing acts as a stop. against fire. In turn, since the bearing 497 does not generally provide a complete seal, the water 493 can stop gases that could possibly escape through the bearing 497. As discussed above and depending on the waste being burned, the water 493 can provide a Suitable seal without the bearing 500. Similarly, circumstances may allow the bearing 497 to function as a complete seal, dispensing completely with the need and presence of the water seal 490. When the bearing 497 provides the seal between the homes 158a and 158b , the vertical seal for the previous one must fall along the line 506. This again provides a closed perimeter for a complete seal. In addition, as suggested by this figure, a fibrous bearing similar to the bearing 497 itself may form the upper, transverse, horizontal seal of the end of the loader, or the lower, horizontal seal of the end of the ash, by itself, or in set with another type of seal such as water seal. Figure 46 demonstrates a water seal 490 and a bearing seal 507 virtually identical to those in the previous figure. However, here the bearing 508 is rubbed against the steel plate 509, which sits in the slit 510 in the refractory 503 of the bottom surface 51 1 of the upper hearth 158a. As the two hearths 158a and 158b move in relation to one another, the slit 510 helps control the movement of the bearing 509 anchored to the lower hearth 158b by the forks 512. If not, all the observations made for the Figure 45 apply here too. Figure 47 represents the transverse, intermediate, horizontal water seal, generally at 512 located between the upper and lower hearth 158a and 158b, respectively. This figure appears very similar to the intermediate water seal 475 of Figures 43 and 44. Here, however, the upper hearth 158a and the lower hearth 158b are connected with the flexible fabrics 513 and 514, respectively, which settle in the water 515 of channel 516. Weight rods 517 and 518 are fixed to the respective bottoms of tissues 513 and 514 to hold them in water 515. Again, the vertical and side seal indicated by line 517 of upper hearth 158a is aligned with the tissue 513 attached to that home. Similarly, the lateral, horizontal seal, falls on line 518 of the lower hearth. These orientations provide a closed perimeter through the joint of the two hearths to create a seal between the fire side of the furnace 519 and the outer side 520. The seal shown generally at 521 in Figure 48 has the same components as the seal 475 of Figure 44. Accordingly, the two figures use the same numbers. However, the seal of the present figure has two additional characteristics. First, it includes the flexible, flexible, and elastic bearing 522 anchored to the lower hearth 158b by the steel forks 523. This bearing 522 serves the same sealing purpose and functions similarly as the bearings 495 and 504 of Figures 45 and 46 , respectively. The seal 521 further includes the bag 523 held in place against the blades 478 and 485 by the support strips 525 and 526, respectively. The bag 523, to provide an effective seal, must completely wrap the blades 478 and 485. It must also exhibit sufficient elasticity to accommodate the movement of the homes 158a and 158b in their pulsed movements 162a and 162b. Finally, the composition of bag 523 should allow it to support the environment of the incineration area 486, or at least as much as it can pass through the fibrous bearing 522 when that article is included in the construction. The material mentioned for the bag 322 of Figures 25 and 26 will suffice for this bag 523 as well. The seal 521 in Figure 48 includes the three components of the bag 523, the water 479, and the fibrous bearing 522. According to the environment of the main chamber 486 of the incinerator, the seal 521 can function adequately with two or only one of the components listed above. In particular, the blades 478 and 485 serve to maintain the bag 523 in the water 479 and also to provide a water seal in case the bag 523 should fail. Accordingly, if the circumstances as discussed above indicated the omission of water 479 (and perhaps channel 480), then seal 521 would not need blades 478 and 485. Figure 49 contains a drawing of the main chamber of the incinerator, indicated generally at 527, very similar to camera 84 of Figure 1 (but on the other side). Chamber 527 includes the upper hearth and the lower hearth 158a and 158b. The cables 531 hang from the circular beams 532a of the stationary structure 533 and encircle the beams 534a of the pulsating hearth 158a. The cables 531a thus serve to suspend the hearth 158a of the superstructure 533 and allow the hearth to oscillate in the somewhat pendulous style of the pulsed movement 162a discussed in the Basic, U.S. Patent. No. 4,475,469, mentioned above. Similar observations apply to lower hearth 158b, which is suspended by wires 531b wrapped around beams 532b of stationary superstructure 533 and beams 534b attached to hearth 158b.

The upper hearth 158a receives the sealing insulation of the transverse seal of the end of the charger and the channel 537; of the lateral, horizontal seal and channel 538a; of vertical side seal 539a; and the transverse horizontal seal of the medium, and the channel 540. Similarly, the sealing perimeter around the lower hearth 158b includes, again, the transverse seal of the medium and the channel 540; the horizontal, lateral seal, and channel 538b; the vertical side seal 539b; and the lower, horizontal, transverse seal of the end of the cornice 541. All the seals listed above are interconnected and form a closed perimeter and thus a complete seal around the homes 158a and 158b to isolate the interior of the incinerator against its exterior. All seals, with the exception of vertical seals 539a and 539b, make use of water in a channel. The vertical seals 539a and 539b, as shown, employ some form of frictional seal or bag seal discussed above. The interconnection of the water seals for the lower house 1 8b is shown below in Figures 50 to 53. A similar design, although with somewhat shorter sides, is also effective in the upper house 158a. The system of interconnected channels for the lower hearth 158b of Figure 49 generally appears at 545 in Figure 50. This system includes the two lateral horizontal channels 546 connected to the upper, horizontal transverse channel 547. The channel system 545 remains stationary on the superstructure 533 of Figure 49. Since similar structures are applied to the channel system 545 for the upper hearth and the lower hearth 158a and 158b, the following refers to a general hearth 158. Water in the side channels 546 and the transverse channel 547 can flow freely from, and towards, each other at the corners 548, one of which appears in Figure 51. As seen there, the horizontal transverse seal channel 547 appears in dashed lines since it lies behind (in the drawing) of channel 546 for the lateral horizontal seal. The two channels interconnect and water from one can flow into the other to provide a continuous seal. The end 552 connects the two channels, and the cover 553, joined by the hinge 554, allows access to the transverse channel 547. FIG. 52 demonstrates a corner 555 of the pulsating hearth 158. The hearth 158 has the side cutter 556 attached to its side wall 557. The end of hearth 158 has the flexible, horizontal fabric of end 418 (as seen in Figure 35). As Figure 52 illustrates, flexible tissue 418 sits firmly against side cutter 556 to prevent passage of gas between them. A similar side blade is fixed to the other end of the fabric 418, not shown in the figure. The continuous and interconnected structure of the side blade 556, the flexible tissue 418, and the side blade, not seen in Figure 52, then sits on the channel structure 545 of Figure 50 filled with water to form a water seal connected and continuous around the three sides of the hearth 158. To complete the seal, two vertical seals would be connected to the bottom of the end 558 of the side channels 546 in Figure 50. A lower (transverse), transverse, and horizontal seal then it would connect to the bottom of the vertical seals to provide a closed perimeter around the home. The hearth 158 of Figure 53 closely resembles that of Figure 52 with the exception that, instead of the flexible fabric 418, it has the stainless steel blade 422 (as seen in Figure 36). Again, establishing a gas-proof meeting along line 559 where side knife 556 and steel blade meet, provides a tight seal at the corner of hearth 158. Figure 54 demonstrates a portion of the side channel 546, seen first in Figure 50, but attached to a section of the immobile outer superstructure 561 of the main chamber of the incinerator. Both drawings show that the side channel includes the pan-shaped channel portions 562 to 567 typically made of a corrosion resistant material such as stainless steel. The casserole channels 562 to 567 allow external access to casseroles 563 to 567 and thus the water from side channel 546 for maintenance. further, the casserole 565 has the plug 571 in its bottom to allow the drainage of water in the channel system. Pan 563 also includes the floating device 574, which serves to maintain water in the channel system at the desired level despite evaporation, overflow, and others. As seen in Figures 54 and 55, pans 562 to 567 have the barrier plate 575 extending from side to side. The barrier plate 575 is immersed in water 576 (at seal 538 of Figure 55) to prevent gases from the combustion fire area 577 from passing over the pan to the exterior area 578. However, the barrier 575 does not extend fully to the bottom of pan 564, leaving an alley 581 at its bottom for water to pass under to, and from, portion 582 of side channel 546 where side cutter 556 sits in the water . The pans 562 to 567, in Figures 50, 54, and 55 can not form a single continuum from one end to the other of the side channel 546 for several reasons. First, the pans can not extend through the support posts 583 of the stationary structure 561. Second, the beams 532b supporting the hearth preclude the location of pans in the sections 584 where they are located. Without the pans in these areas, channel 546 takes the "U" shape that the bottom of channel 587 gives it, which occurs behind poles 583 and behind sections 584. However, side channel 546 provides the continuous groove 582 in which side blade 556 of hearth 158 sits (from Figures 52 and 53). Obviously, a gas-proof enclosure must exist between channel 546, pans 562 to 567, poles 583, groove 582, and barrier plates 575 to prevent gas from leaving the combustion environment 577, in its inside, towards 578 outside. Other details of the lateral, horizontal seal appear in Figures 55 and 56. There, the hearth 158 carries the refractory lining 590. The tubes 591 pass through the refractory 590 of the wall 592 to provide air below the fire to the debris home burners 158. The vertical wall of the refractory 592 has the rising portion 593 directed towards the interior of the incinerator. This emerging portion 593 serves to lock the debris that is pushed from the center of the home and to the side, so that it is not caught in the area 596 between the hearth 158 and the stationary roof 597. The roof 597, in turn, bears the lining refractory 598. The roof flank 599 has the 600 tubes that pass through it to provide air above the fire to the burning trash. The roof 597 has the projecting portion 603 which sits on the emerging area 593 of the hearth 158. The projection 603 also helps to prevent material, dust, and others from entering the space 596.

Figure 57 simply demonstrates the three pulsatile homes 158a, 158b, and 158c arranged in tandem. Each has its own lateral water seal, horizontal 538a, 538b and 538c, respectively. Figure 58 demonstrates the lateral, horizontal water seal 538, like that of Figure 55. In addition, it has the fibrous bearing 606, which sits in the space 596 between the hearth 158 and the ceiling projection 603. The forks 607 alloy anchor bearing 606 to refractory 590 of flank 592 of hearth 158, and to steel plate 608. Fibrous bearing 606, accordingly, moves with hearth 158, and is rubbed against steel plate 609 covering the refractory 610 of the roof projection. Accordingly, the bearing 606 must have a lubricated surface 61 1 where it meets, and wears against, the steel plate 609. The hearth in Figure 58 moves in and out of the plane of the paper. Clearly, the fibrous bearing 606 must accommodate that horizontal movement. In addition, during its horizontal movement, the hearth 158 also has a component of vertical movement. For it to function properly under these conditions, the bearing 606 must exhibit sufficient flexibility to withstand compression as it is squeezed between flank 592 and projection 603. Still, it must also have sufficient flexibility to expand and fill the same space as the hearth 158 moves away from the projection 603. The observations concerning the fibrous pads 495 and 504 of Figures 45 and 46, respectively, apply equally here. Figure 59 also demonstrates the fibrous bearing 613 anchored to the flank 529 of the hearth 158 by the steel forks 614. In this situation, however, the bearing 613 sits and moves against the lubricated steel plate 615 in the groove 616 below the refractory 610 in the stationary projection 603. As in Figure 58, the drawing demonstrates the water seal 538 in addition to the bearing 613. In certain situations, the bearing can be effective by itself in any situation. Figure 60 appears to be virtually identical to the previous figure with the exception of the addition of the baggie 618 seated in channel 582 and which wraps blade 556 completely. Strip 619 connects pouch 618 to hearth 158, and strip 620 attaches pouch 618 to pylon 583 of the stationary structure in the same manner. As in Figure 48, bag seal 618 results in a triple seal for home 158, including water 576, bearing 613, and bag 618. Not all of these are required for a specific situation. In particular, the removal of water 676 can obviate blade 556. The discussion for the transverse, horizontal seal of Figure 48 applies here for the lateral, horizontal seal. Figures 61 to 65 illustrate the use of various means 623 in channel 582 attached to post 583 of the stationary structure. In the manner discussed above, the insertion of the blade 556 in the middle 623 provides a lateral, horizontal seal. Regardless of its exact nature, the means 623 must allow the home to travel through its pulsed and arcuate movement without damaging the channel 582, the blade 556, or the medium itself 623. In addition, any of the means may be used with any of the other seals arranged above, such as the fibrous bearing, the sachet, or both together, to form a multiple seal.

In any case, Figure 61 demonstrates the means 623 discussed in the preceding figures, which takes the form of water 576. In Figure 62, the sand 626 sits in the side channel 582 and acts as the sealing means. In Figure 63, the fine mesh sieve 627 is welded near the bottom of the channel 582. The sand 628 then sits on the sieve 627. The conduit 631 enters the channel below the sieve 627 and can introduce air or any other gas through its opening 632 to help further sandify the 628 sand when necessary. As well as in the discussion that refers to Figures 39 to 42, air can be introduced continuously, intermittently, or not at all. Such air can also provide a positive pressure to help prevent the escape of combustion gas from the incinerator furnace area as well as the blower 165 of Figure 2. The bubble type material 635 and 636 such as pebbles, alumina, or silica, considered in Figures 64 and 65, respectively, replaces sand 626 and 628 of Figures 62 and 63. If not, the observations covered above apply here as well.
