The front wall has a first opening and a second opening formed therein. The second opening is disposed adjacent to the bottom wall between the first opening and the bottom wall. The rear wall has at least one inlet aperture formed adjacent to the bottom wall. The first side wall and the second side wall each have at least one outlet aperture disposed adjacent to the top wall. The incinerator further has a door that is movable between an opened position, whereby waste may be disposed on a grate suspended inside of the main body, and a closed position, whereby the door may cover the first opening. ## Claims ### Claim 1 An incinerator, comprising: a hollow main body with a front wall, a rear wall, a first side wall, a second side wall, a top wall, and a bottom wall, the front wall having a first opening and a second opening formed therein, the rear wall having at least one inlet aperture formed therein adjacent to the bottom wall, the first side wall and the second side wall each having at least one outlet aperture formed therein adjacent to the top wall; a door movably disposed on the front wall adjacent to the first opening, the door movable between an opened position and a closed position, the first opening uncovered by the door in the opened position, and the first opening covered by the door in the closed position; and a grate suspended inside of the hollow main body, the grate disposed between the first opening and the second opening in the front wall. ### Claim 2 (depends on 1) The incinerator of claim 1, wherein the at least one inlet aperture defines a first aperture area and the at least one outlet aperture defines a second aperture area, the first aperture area being greater than the second aperture area. ### Claim 3 (depends on 2) The incinerator of claim 2, wherein the at least one inlet aperture includes seven inlet apertures formed in the rear wall and the at least one outlet aperture includes three outlet apertures formed in each of the first side wall and the second side wall. ### Claim 4 (depends on 3) The incinerator of claim 3, wherein each of the inlet apertures and the outlet apertures has an opening diameter of about 0.875 inches. ### Claim 5 (depends on 1) The incinerator of claim 1, wherein the at least one inlet aperture and the at least one outlet aperture are chamfered. ### Claim 6 (depends on 1) The incinerator of claim 1, wherein the hollow main body is made of 304-L grade and 14-gauge stainless steel. ### Claim 7 (depends on 1) The incinerator of claim 1, wherein the grate abuts each of the front wall, the rear wall, the first side wall, and the second side wall. ### Claim 8 (depends on 7) The incinerator of claim 7, wherein the grate is welded with tack welds to each of the front wall, the rear wall, the first side wall and the second side wall. ### Claim 9 (depends on 1) The incinerator of claim 1, wherein the second opening is formed in the front wall adjacent to the bottom wall between the first opening and the bottom wall. ### Claim 10 (depends on 1) The incinerator of claim 1, further comprising a latch disposed on the front wall and configured to selectively bias the door in the closed position. ### Claim 11 (depends on 10) The incinerator of claim 10, the door further having a wedge disposed on an outer surface thereof, the wedge having an angled surface configured to cooperate with the latch to selectively bias the door in the closed position. ### Claim 12 (depends on 11) The incinerator of claim 11, wherein the door is disposed on a first plane and the angled surface of the wedge is disposed on a second plane, the first plane oriented transverse to the second plane and defining a wedge angle therebetween, the wedge angle being between about 5 degrees and about 25 degrees. ### Claim 13 (depends on 12) The incinerator of claim 12, wherein the wedge angle is about 15 degrees. ### Claim 14 (depends on 12) The incinerator of claim 12, wherein the latch is connected to the front wall and selectively movable about an axis of rotation between an unlatched position and a latched position, the latch spaced apart from the wedge where in the unlatched position and the latch abutting the wedge where in the latched position. ### Claim 15 (depends on 14) The incinerator of claim 14, wherein the latch has a wall connecting portion and an elongate handle portion, the elongate handle portion disposed on an elongate axis that is oriented transverse to the axis of rotation and defining a handle angle therebetween. ### Claim 16 (depends on 15) The incinerator of claim 15, wherein the handle angle changes when the latch is in the latched position due to an outward bending of the elongate handle against the angled surface of the wedge, the outward bending providing a spring force to bias the door in the closed position. ### Claim 17 (depends on 16) The incinerator of claim 16, wherein the handle angle is about 95 degrees relative to the axis of rotation where the latch is in the unlatched position, and the handle angle is about 90 degrees relative to the axis of rotation where the latch is in the latched position. ### Claim 18 A method of incinerating waste, comprising: providing an incinerator including a hollow main body with a front wall, a rear wall, a first side wall, a second side wall, a top wall, and a bottom wall, the front wall having a first opening and a second opening formed therein, the rear wall having at least one inlet aperture formed therein adjacent to the bottom wall, the first side wall and the second side wall each having at least one outlet aperture formed therein adjacent to the top wall, a door movably disposed on the front wall adjacent to the first opening, the door movable between an opened position and a closed position, the first opening uncovered by the door in the opened position, and the first opening covered by the door in the closed position, and a grate suspended inside of the hollow main body, the grate disposed between the first opening and the second opening in the front wall; disposing the waste on the grate; and igniting the waste, whereby the waste is incinerated. ### Claim 19 (depends on 18) The method of claim 18, further comprising a step of one of i) orienting the hollow main body so that the at least one inlet aperture face a direction of a prevailing wind, and ii) attaching a blower to at least one inlet aperture to provide forced air to the hollow main body. ### Claim 20 An incinerator, comprising: a hollow main body with a front wall, a rear wall, a first side wall, a second side wall, a top wall, and a bottom wall, the front wall having a first opening and a second opening formed therein, the rear wall having at least one inlet aperture formed therein adjacent to the bottom wall, the first side wall and the second side wall each having at least one outlet aperture formed therein adjacent to the top wall, and the at least one inlet aperture defining a first aperture area and the at least one outlet aperture defining a second aperture area, the first aperture area being greater than the second aperture area, and each of the at least one inlet aperture and the at least one outlet aperture having a chamfered edge; a latch rotatably affixed to the front wall of the main body adjacent to the first opening, wherein the latch has a wall connecting portion and an elongate handle portion, the elongate handle portion disposed on an elongate axis that is oriented transverse to the axis of rotation and defining a handle angle therebetween; a door movably disposed on the front wall adjacent the first opening, the door movable between an opened position and a closed position, the first opening uncovered by the door in the opened position, and the first opening covered by the door in the closed position, the door having a wedge formed on an outer surface of the door, the wedge having an angled surface configured to cooperate with the latch disposed on the front wall to selectively secure the door in the closed position, wherein the door is disposed on a first plane and the angled surface of the wedge is disposed on a second plane, the first plane oriented transverse to the second plane and defining a wedge angle therebetween, the wedge angle being between about 5 degrees and about 25 degrees, and wherein the handle angle changes when the latch is in the latched position due to an outward bending of the elongate handle against the angled surface of the wedge, the outward bending providing a spring force to bias the door in the closed position; and a grate suspended in the hollow main body with a plurality of tack welds, the grate disposed between the first opening and the second opening in the front wall, the at least one inlet aperture being disposed above the grate.
