Description

~ -This invention relates to an incinerating apparatus, but more specifically pertains to an incinerating apparatus that has utility for providing energy conversion and does so ~:
with significantly reduced pollution.
For the past decade considerable emphasis nas been placed upon the environmental aspects of our society, and most .
prominent has been the reduction in the amount of industrial and residential pollutants that are emitted into our atmosphere.
The most slgnifi.cant piece of evidence of this concern has been the culmination of legislation in 1967 under the titl.e of the "Air Quality Act of 1967", more commonly known as the Clean ~ir Act. Generally, the Act was enacted for the primary purpose to protect and enhance the quality of the ~ation's air resources so as to promote the public health and welfare and the productive capacity of its population. More specifically, the Act stimulates cooperative activities of the various state ~urisdictions, and their local laws, to provide for uni~ormity of legislation that seeks the aforesaid ultimate goal of the prevention and control of air pollution. Thus, many state legislatures, an~ municipal legislative assemblies, have fulfllled this need by also enacting laws that stringently control and regulate the quantity of pollutants that are emitted in their arnbient atmospheres. -~
~ ut, even in view of the foregoing, many if not most of the incinerating, burning, and cooking units that readily give off their gases of combustion to the atmosphere .,,"~

ll~S;~2S

have not been designed to fulfill the purposes of such enacted legislation, that, as previously explained, present strictures on the quantity of pollutants that may be disseminated in gaseous form into our atmosphere. ~s an example~ the various style of portable cooking units, Oenerally identified as .
barbecuing devices, and such as sho~n in the United States patent to Tid~ell, l~o. 3,991,666, discloses a rather complex pit and oven combination whlch readily burns charcoal or other combustible materials under an open grate, thereby emitting its polluting gases and smoke directly into the surrounding atmosphere. The United States patent to ~ryrough, No. 3,602,161, discloses an incinerator for trash or other waste material which includes a lower trash-receiving chamber, and an upper srnoke incinerating chamber, both for the purpose of providing for extra burning Or its deposited waste material, but it can be seen that its upper charnber provides for direct discharge of its smoke unlnhibitively out of its integral stack and to the atmosphere, all without any supplemental treatment or rmeans to provide reduced contamination from such discharge. One of the most notorious of pollutants is the srnoke given off of the burning of various elastomeric and polymeric materials, such as rubber and plastics. The United States patent to Stockman, l~o. 3,572,265, recognizes this problem, and provides some means for remedying the same through the use of multiple burners for initially heating and gasifying of such l~S3~S

solld waste, and with a further attempt to reduce the carrie~
pollutants in the fumes by causing an after burning of said fumes within the emitting stack. Baffling means have been tried fo~ reducing pollutants~ and as can be seen in the United States patent to Overfield, No. 3,334,598, an oil .fired housenold garbage incinerator incorporating breather ports for assuring what this device seeks as the prompt discharge of its gases and fumes, at least during initial garbage i~,nition. :
The foregoing incinerators have been helpful in providing some reduction in the quanti.ty of pollutants admitted to the atmosphere, over the type of incinerating devices which were earlier devised, such as shown in the United States patent to Egan, No. 2,127,328, but, by and large, these more contemporary incinerators are more concerned with providing means for reduction of solid waste material, on a more bull~ scale, and are not generally concerne~ with the amount of pollutant;s that may be Generate~ therefrorn, once the discarding of the.solid waste has bcen effected, as through incineration.
Various other incinerators of the foreLoing types are shown ln the United States patent to 'iIatteini, No. 3,412,697;
the United States patent to Franzheim, No 3,04LI,421, the United States patent to Royer, No. 2,~82,~42; the United States patent to ~iartmann, No. 2,956,526; the United States patent to ;`~lorgan, No. 3,o89,440; the United States patent to Shaw, ~l~S~25 i-~o. 3,~10,179j an~ the two United States patents to ~Ioskinson, .io. 3,215,1Cl, and iio. 3,24~,17~. These are all e~amples of the known extent of the development of the state of the art with respect to this particular field of technology.
In view of the foregoing, it is, therefore, the principal object of this invention to provide an energy converting apparatus which combines the feature of solid ~Jaste incineration, substantially reduced pollutant discharge, and energy conversion by way of steam pressure or provision of a neat source, as for use in cooking or heating, all embodied within a single structure.
Anot~er significant object of this invention is the provision of means for providing total cornbustion of a burnable solid waste material and an after burning of its generated gases of combustion in an effort to significantly reduce if not eliminate the polluting characteristics normally carried by smoke or other discharge into the atrnosphere.
Anotner ob~ect of this invention i5 to provide for the use of dual combustion chambers for inducing forced burnlng at significantly elevated temperatures of solid -~
waste material for attaining complete combustion.
Yet another ob~ect of this invention is to furnish an incinerating apparatus that may incorporate boiler tubes for providin~ a suppiemental means for generating of usable energy.

11~15~25 Yet another object of this invention is to provide a solid waste incinerating apparatus wllich can give off a significant amount of tapable heat energy that rnay be used for heating purposes, such as for a living enclosure, or even for use for cooking, or other heat consuming purposes.
Yet still another object of this invention is to provide a novel exhaust stack for an incinerating apparatus that assures the full exposure of the heated flue gases to an abundant quantity of oxygen to assure complete combustion and elimination of the polluting aspects of smoke before its discharge to the atmosphere.
Another object of this invention is to provide means for purifying the exhaust from an incinerating apparatus so that smoke discharge will be clear, and free of any soot and the usual unspent hydrocarbons that normally furnish the deleterious polluting aspects to this type of smoke exhaust.
Yet another ob~ect of this invention ls to provide an lncinerating apparatus having supplemental beneficial aspects as a secondary energy source that is easy to use, compact in structure, and low in cost to manufacture.
Yet a further ob~ect is to provide an incinerating apparatus having the foregoing advantages and ~rhich is readily portable for ease of mobility around the property.
These and other ob~ects will become more apparent to those skille~ in the art upon reviewing the summary of this invention, and upon undertaking a study of its preferred ilC~S32S

embodiment in view of the drawings.
This invention contemplates the formation of a housing, preferably wheel mounted to enhance its portability, with its housing being segregated into a pair of combustion chambers~
one above the other, the first chamber comprising a primary combustion charnber, and into which rnost of the solid waste hydrocarbon material, and wood, leaves, etc., will be inserted, and having the secondary combustion chamber arranged directly thereabove and into wnich additional quantities of combustible material will be inserted so as to provide for secondary burning not only for eliminating its waste, but to provide for an afterburning of the flue gases and before they are discharged from the apparatus stack. As is well known, various types of trash may give off slight gases in the category of methane, ethane, or ethylene, and when the trash is burnecl, in addition to its evolved gas, are combusted into carbon dioxide and molsture or water vapor. In the concept of climinatln~
pollution, particularly from flue gases and smoke, it ls desirable that the end product ~enerated from the same will be a pure carbon dioxide and water. L3Ut achieving this has not been, in the past, a primary goal, and since the incipiency of the various clean air laws, as previously explained, to attain a more pure or clearer flue gas, or more specifically, a smokeless trash destruction by combustion, such has just not been an easy feat to attain.

The current invention recognized the fore~oing problems, provides a particularly styled incinerating device which ~;~
seeks to attain a high temperature of heat, during its operation, maintain the same for some period of time, so that all of the flue gases generatecl within the apparatus, and before the same are exhausted, will be sub~ected to these elevated ternperatures, fully oxidized, and completely combusted, thereby eliminating the conveyance of any Or the entrained hydrocarbons, which are usually the deleterious particles forming the smoke, before they are conveyed for discharge to the atmosphere. Secondary benefi.ts derived from the current invention, structured as previously explained, include means for utilization of the solid waste or burnable cellulostic :~
material, as for example, for generating of a heat source, which can be tapped for heatin~ of the residence, or other building, and likewise furnish energy ~or cooking, or even for in~ustrial uses. ~hus, other national resources or energy that are very apparently becoMing in short supply, such as gas or electricity, can be conserved. Thus, an invention of this type, as distinct fro~n the earlier type of incincerating devices made available, and as previously explained, can provide a form of solution to the elimination of solid combustible waste, while simultaneously offering, at least on the residential or small industrial scale, a means for conserving energy by attaining its supply from thi.s alternative source, and do so with little formed pollution.

l~S3Z5 It is essential thatthe current invention maintain a high degree of temperature within its apparatus, so that as previously explained, full combustion will take place and incomplete combustion eliminated, ~hich is usually caused from lower temperatures generated within certain types of earlier incinerating devices. It is this incomplete combustion that allows for the various hydrocarbons to become entrained ~ithin the flue gas exhaust, and be harmfully discharged into the atmosphere. To attain such elevated heat, the current invention does incorporate the dual combustion chambers, one above the other, and each of which chamber has associated therewith a feed~chute that can provide for a batch or continuous flow of cornbustible waste material into its respective chambers. l1he continuous supply of combustible hydrocarbon material into these chambers maintains a continuous burn, and the development of signifioant heat therein during functioning. The invention further comprehends the use of even forced burning in order to maintain the elevated heat desired, slnce it has been found, through experimentation, that most -of the carbonaceous components within flue gases can be fully burned at a temperature above 1500 degrees F. An ex~nple of forced burning may include the use of one or more cornpressed gas burners, such as propane, or the lilce, which -~
may discharge its flame directly into the primary and/or secondary combustion chambers for stimulating a continuous 5~5 heavy flame within said chambers ~n order ~o insure full combustion. Furthermore the flue of the apparatus, that which communicates with the secondary and upper combustion chamber~
may extend slightly do~mwardly therein so as to provide a momentary retention of the heated gases within the upper chamber and provide for their continuous exposure to the high heat generated 1,rithin the combustion chambers before ~:
they are discharged from the stack to thc atMosphere.
T~lrough usage of this invention, and with the use of various temperature and chemical detecting devices the temperature and component profile of this ourrent apparatus provided the following results:

Tests have indicated that the temperature withln the various combustion chambers have even exceeded 2000~
and rnaintained at that temperature, in order to attain the complete combustion desired from this invention.
Various other attributes of this invention include the locating of the apparatus withln a spec:lally desigrled enclosure, one that may be vented, but yet provided with sufficient coverage so as to prevent the entrance of any elements therein. Thus, at that instance where the device may be used for generating steam pressure, it can be fully operated even durin~ inclement weather, so as to furnish that type of supplemental energy source continuously, and without obstruction. The uniquely designed stacl~ of this invention ;3~S

incorporates means for the continuous feeding of oxygen to the discharging flue gases, so that even a final slight combustion may take place upon exposure of the added oxygen to the heated gases, so as to eliminate, fully, tlle deleterious hydrocarbonaceous aspects of smoke before it reaches the atmosphere. During testing, this invention, when properly operating, and burning waste material, discharges flue gases that are clear to vision, thereby complying with local ordinances against the discharge of any smoke from residential burning.

In referring to Figure 1 of the drawings, there is disclosed the incinerating and energy converting apparatus 1 of this invention. As can also be seen in ~igures 2 through Ij, the apparatus includes a housing 2 having a flue 3 extending upwardly from the upper surface of said housing, wiht the housing 2 having a fire box, as at 4, provided therein and in which the fires of combustion occur during usage of this invention. The housing firebox is formed into two : -13~

S3~5 compartments, comprising the primary and secondary combustion chambers 5 and 6, respectively, and in which the burning of the combustible hydrocarbon waste materials occurs. Pivotally mounted proximate its upper end, as at 7, is a closure means 8, and which rests upon a lower base 9, being held thereto by means of a locking mechanisrn 10.
Extending downwardly from the housing 2, and the base 9, is a compartrrlent 11, which may be used for storage of other instruments, or even kindling, having access thereto through the door 12. Extending from either side of the storage compartment 11 are the standards 13, which cooperate for holding an axle 14 for mounting of the rear wheels 15.
ProJecting downwardly at the frontal end of the apparatus, and beneath the base 9, is a frame member 1~ that is useful for pivotally mounting of the directional wheel 17, as shown.
Connecting with the yollc 18 of the wheel 17 is a tow bar 19, having a handle 20 located at its forwardrnost end, and which ls useful for providing the rneans for pulling of the apparatus, in addition to giving the direction of movement to the front wheel 17, and therefore, the entire apparatus.
As can be seen, the yalk 18 has a shaft 21 extending upwardly therefrom, and which is bearing mounted within the frame member 16. The tow bar also furnishes a brake Ll2 that can be pressed against the tire 17 for curtailing movement.

11~5325 As previously coJnmented, the firebox ~ is segregated into a pair of upper and lower, secondary and primary combustion chambers, respectively, and which chambers are separated by means of the grate 22. ~hus, any waste material for burning deposited within the primary cornbustion chamber 5, when ignited, will direct its flame upwardly through the grill 22 and furnish a burning of similar material deposited within the secondary combustion chamber 6. To attain deposition of waste combustible material into firebox there is provided a chute means associated with each of the combustion chambers.
An upper chute means 23 is useful for feeding combustible material into the secondary combustion chamber 6, while a lo~1er chute means 24 facilitates the delivery of the combustible material into the prirnary combustion chamber 5. It may also be commented that in order to insure the adequate build up of heat, and retention of the same, within the fire box that insulation, such as refractory material, as in the category of DB i~o. 1 firebrick, as at 25, is provided for surrounding the said firebox, and therein insure an adequate build up Or heat within the same. And, this firebrick insulation is surrounded by the housing 2, which rnay be formed of a sheet metal material of sufficient thickness to provide structural ri~idity to the said housing, withstand deterioration, particularly that which may be caused by continuous exposure to heat and some moisture, but at the same time, being sufficiently thin so as to reduce the wei~ht of the entire apparatus.

~g~ s Provided below the lower chute 24 ~ and in the base 9 may be located structural means useful ~or supporting a compressed gas burner~ such as tne propane burner 2G, and which directs its noz~le 27 into the lower combustion chamber 5 for eJection of a flarne into the same. This particular burner is optional in the ~evice, since it has been found, through experimentation, that the degrees of heat built up in both the primary and as a result the secondary combustion charnbers of this inventlon are adequate for furnishlng that heat found nece~sary for attaining full combustion of all of the hydro-carbon aspects of the waste materials being burned. Also located within this base 9, and rnore specifically formed through its frontal panel 2~, is a vented opening 29 that allows for entrance of air into the vicinity of the firebox, so as to provide for the access of oxygen for feeding of the fires of cornbustion therein for sustaining the operations of this invention.
It can be seen that the flue 3 of the hou3ing, may e~tend partially downwardly into the secondary cornbustion chamber 6, 20 as can be seen at 30, and this is useful for providing for some accumulation of heat at the upper regions of the secondary combustion chamber so that sufficient hotness is rnaintained at that location, and which stimulates the complete burning of all of the waste materials, in addition to preventing the ; `

entrainment and exhausting of any of the carbonaceous elements that may be exhausted by the stack of this apparatus. In referring to also Figures 7 through 9 of the drawings, mounted upon the flue 3 is the exhaust stack 31 of this invention.
This exhaust stack includes a series of cylindrical sections as at 32 and 33, with the section 32 being of greater diameter than the flue 3, but of lesser diameter than the outer concentrically arranged staclc section 33. These sections are all secured together by means of a bracing, as at 34, and a series of baf~les, as at 35 and 36, may be partially arranged across each of the stack sections so as to provide some cascading of the flue gases of exhaustion as they rise upwardly through the stack for emission into the atmosphere.
In any event, because of the different diametric sizes of these various stack sections, and their partial overlapping in their shown vertical arrangment, sufficient clearance is provided, as at 37 and 3~, for allowing the reentrance o~
air~ and more speciflcally oxygen, into the stack for insuring complete combustion of the flue gases as they rise out of the apparatus. A truncated shaped stack section 39 is held by bracing 40 to the larger stack section 33, arranged therebelow, and with thetruncated stack section having a reduced diameter opening, as at 41, so as to provide for a channelling of the exhaust gases out of a smaller or confined area when discharged into the atmosphere. As can be seen in Figures ~ and 9, --17~

- . . .. . . .. . . ... .. .

11~53~S

various bracings, as prev~ously explained at 34, are useful for securing these various stack sections, including the upper truncated stacl~ section, by means of its bracing 40, togetner, and in comblnation provicling for their mo~nting upon the top of the apparatus flue 3.
Since this invention does comprehend various energy conversion means, furnishing supplemental usage for the apparatus, by referring to Figure 10, it can be seen that the apparatus 1 ma.y be used in combination with a boiler 2 for providing a generation of steam, and which steam may be used for various heating or pressure usage, as for turning of a turbine, wllen used in the generation of electricity.
As can be seen, the upper stack portion 113 functions as a hood upon the other stack section 31, as previously analyzed, and which nood 43 cornrnunicates with the ductwork 44 for channelling the flue gases through the boiler, and wherein they may heat any fluid contained within the boiler tubes (not shown) for use in the generatiorl of stearn or the like.
A low pressure fan or blower 45 may be used for attracting the flue gases through the hood 43, and the duct 44, to the vicinity of the boiler, and then exhaust the flue gases out o~ its port 46, for venting thern to the atmosphere.
As can be seen in Figure 11, the boiler 48 may :
simply dispose lts tubes 49 in heat exchanging relationship through the various combustion chambers within the firebox 50, wherein the heated combustion gases may be used for creating high pressure stear,l, in the boiler, for other uses, as for example, in the generation of electricity, to provide heat, to run air conditioning or heating systems, or the like, as previously explained. In this particu].ar example, the spent gases of the combustion, which will have been ren~ered sufficiently clear of any hydrocarbons by means of the primary and secondary combustion that takes place within the firebox 50, will be vented to the atmosphere through the stack 51.
Figure 12 discloses an enclosure 52 that may be used for housing of theapparatus 1, 50 that the apparatus may be continuously fired for indefinite durations and freed from exposure to increment or cold weather conditions. Tne enclosure includes a series of walls 53 and 5ll, resting upon a bottom frame 55, and which bot~om frame may include various leveling shims, as at 56, for allowing installation of the enclosure even on rough terrain. ~ach of the wall ~anels 53 and 54 include a serles of plvotally openin~
vent panels 57, useful for being opened so a.s to provide for this supplyin~ of air, and oxygen, to the interior of the enclosure for feeding the fires of combustion taken place within the incinerating apparatus 1. The upper roof of the enclosure 52 may be slanted, as shown at 58, with the ridge of the roof lncorporating one or more roof vents 59, which may be pivoted open, as can be seen shcematically :

~S3ZS

within ~he drawing, so as to provide for ready egress of the spent flue gases out of the enclosure. A cupola section, as at 60, is held by a series of supports 61, upwardly from a roof vent 59, so as to allow for the exhausting of the gases of combustion from the enclosure, while preventing the entrance of any rain, snow, or other elements into the interior of the enclosure during its usage.
It has been found durin~ experimentation with this apparatus that the various upper surfaces of the apparatus, :~
such as the upper surface 62 of the housing 2, or the upper surface 63 of the closure mernber, or even the upper feed chute 23, are sufficiently heated during the usage of this apparatus so as to support the cooking o~ any items or foods resting thereupon, thereby allowing this device to have ready usage, as for recreational purposes, when located at, for example, a clubhouse, or the like. Thus, this particular invention has ready application for a variety of purposes, and, as lts narne implies, provi~es for not only elimination Or waste materials, but while said waste materials are being combusted, the device may ~e used for energy conversion purposes, for providing heat, steam for generation purposes, or even for cor.~non cooking, as at a vacation cottage, or the like. `^
Various modi~ications to the structure and usage of this invention may occur to those skilled in the art upon --20~-~s~

reviewin~ the subject matter of this invention. Such modifications, if witnin the spirit and scope of this invention, and if encompassed by the clairns~ are intended to be protected by any patent issuing hereon. ~he description set forth is made ~or illustrative purposes only.
