ATTCI RN EYS 2,988,023 METHOD OF AND APPARATUS FOR BURNING Anthony I. Osswald, 66 Inter Park Ave., Buffalo, N.Y. Filed Nov. 18, 1958, Ser. No. 774,619 1 Claim. (Cl. 110-8) This invention relates to an incinerator.

The object of the invention is to provide an incinerator which is adapted to be used for burning trash, garbage or the like, so that the products of combustion leaving the incinerator will be substantially free of odor, impurities, and the like. Y

Another object of the invention is to -provide a method of and apparatus for burning trash and the like wherein the iinal products of combustion leaving the incinerator are substantially free of impurities such as carbon since a highly eective and novel means is provided for insuring that complete combustion takes place.

A further object of the invention is to provide an incinerator which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent in the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same.

FIGURE 1 is an end elevational view of the incinerator of the present invention.

FIGURE 2 is a side elevational view of the incinerator.

FIGURE 3 is a horizontal sectional view taken through the incinerator.

FIGURE 4 is a vertical sectional view taken through the incinerator.

yFIGURE 5 is a sectional View taken on line 5--5 of FIGURE 4.

Referring in detail to the drawings, the numeral indicates the incinerator of the present invention which is shown to comprise an outer hollow housing 11, and the housing 11 includes a horizontally disposed bottom wall 12, spaced parallel end walls 13 and l14, and the housing 11 further includes an arcuate top wall 16 which is provided with an air inlet 15.

The numeral 17 indicates a horizontally disposed grate, and the numeral 18 indicates a hollow casing which is arranged within the housing 11. The casing 18 includes spaced parallel vertically disposed end walls 19 and 20, as well as spaced parallel vertically disposed

side walls

21 and 22 and an arcuate top wall or member 23. The members or walls of the casing 18 are spaced inwardly from the walls of the housing 11 so as to dene an air space 24, and the inlet air opening communicates with the space 24, so that the air can be preheated as later described in this-application, and this preheated air is adapted to be used for supporting combustion in the incinerator. The numeral 25 indicates slots or openings which permit the air from the passageway 24 to enter the bottom of the incinerator.

There is deiined within the incinerator an upper chamber 26 and a lower chamber 27. The numeral 28 indicates a generally horizontal bathe which has one end spaced from the end member of the casing 18, as for example as shown in FIGURE 4 so that the products of combustion from the lower chamber 27 can pass through the opening 29 and enter an approximately L-shaped passageway 3l that is used for the products of combustion. The passageway 31 is defined between the baille 28 and a partition 30, and the numeral 32 indicates a generally vertical portion which has its lower end communicating with the horizontal portion of the passageway 31.

Arranged in communication with the lower chamber States Patent i Patented .lume 13, 1961 ICC 27 is a plurality of burners 33 which may be of conventional construction and which may be supplied with fuel from' a suitable source of supply. There is further provided a burner 34 which is arranged contiguous to the upper end of the portion 32 of the passageway 31, and the upper burner 34 communicates with the upper chamber 26 in the incinerator. The numeral 35 indicates a flue which extends through the wall 14 of the housing 11 and communicates with the interior of the upper chamber 26 las shown in FIGURE 4. The numeral 36 indicates an opening or inlet through which trash, garbage or the like can be inserted into the chamber 27, and a door 37 is mounted to move into and out of closed relation with respect to the opening 36. Thus, when trash is to be burned, the door 37 is to be moved to open position and then the door 37 can be closed.

The housing 11 further includes vertically disposed

side walls

38 and 39, which are spaced outwardly from the

side members

21 and 22 of the inner casing 18 whereby the previously described air passageways 214 are provided.

From the foregoing, it is apparent that there has been provided a method of and apparatus for burning trash, garbage or the like. In use, the trash or other material to be burned is adapted to be loaded into the lower chamber 27 through the opening 36, it being understood that the door 37 is rst moved to open position and after the trash has been inserted into the chamber 27 the door 37 is closed. The

burners

34 and 33 are adapted to be actuated or energized and these burners may be gas fired or electrically operated and it is to be noted that the grate 17 provides a support -for the trash which is being burned up. With the burners 33 functioning or operating it will be seen that the trash in the chamber 27 will be ignited and the exhaust gases or products of com-v bustion from this ignition will pass up to the opening 27' and these products of combustion will then pass through the horizontal portion of the passageway 31, and then to the vertical portion 32. In the event that the products of combustion contain impurities or carbon which has not been fully burned, the secondary burner 34 will further ignite these products in the chamber 26, so that the waste gases which pass out through the ue 35 will be free of carbon or the like so that the waste gases will not contain any odors or other impurities.

The air for supporting combustion enters the incinerator through the opening 15, and this air then passes down through the spaces 24. It is to be noted that the parts are arranged so that this air passes downwardly in heat exchange contact with the inner casing 18 so that the incoming air will pick up some of the heat from the inner casing whereby the air will be preheated. This preheated air will then pass through the slots 25 and up through the grate 17 so as to support the combustion. Since the air is preheated, the incinerator will be able to operate more eciently.

Thus, it will be seen that there has been provided a lower zone in which the trash, garbage or the like is first burned, and wherein there is further provided an upper zone 26 wherein the products of combustion resulting from the burning in the lower zone are exposed to the action of a secondary burner 34 and this insures that the waste gases passing out through the llue 35 will be practically yfree of any carbon like material which has a tend` ency to cause smoke that is obnoxious to smell or View or breathing in.

The parts can be made of any suitable material and in different shapes or sizes.

Suitable baflies can be used wherever desired or required, and a suitable means can be provided for emptying the incinerator of ashes. 'I'he incinerator can be used in industrial locations, or else it can be used for domestic installations. The burners may operate on a suitable fuel such as oil, gas, or the like, or else they may be electrically operated.

The incinerator can be used for burning any type of material and the incinerator is especially suitable for burning carbon containing material of a high burning point. Since the waste gases which pass out through the flue 35 will be practically odorless and colorless, the incinerator is especially suitable for use around buildings, homes, and the like, since the air will not become polluted, and clothes which may be hanging on clotheslines or the like will not become contaminated. The heat from the burning process is transferred to the incoming air so that the preheated air can make the process more efficient.

The device is ruggedly constructed and consists of a minimum number of parts and requires no manipulation during the use thereof. It will be seen that there has been provided an apparatus and process of burning wherein combus-tible materials can be burned in such a manner so that smoke and obnoxious odors are prevented from contaminating the atmosphere. The incinerator can be used for burning any suitable type of material.

Minor changes in shape, size and rearrangement of details coming within the eld of invention claimed may be resorted to in actual practice, if desired.
