Incinerator for domestic and industrial solid, semi-liquid or liquid waste

Claim 2

An incinerator for domestic and industrial waste comprising, a frame, a rotary oven mounted on said frame, said oven being in the shape of a truncated cone, means for rotating said oven, a stationary pre-combustion chamber connected to one end of said oven and communicating therewith, a stationary post-combustion chamber connected to the other end of said oven and communicating therewith, burners associated with each of said chambers, said precombustion chamber receiving said waste to be incinerated, an exhaust cyclone, gas exhaust ducts connecting each of said chambers to said cyclone, a damper isolating each of said chambers from the gas exhaust ducts and said cyclone whereby the burned gases may be directed against the direction of flow of waste or with the direction of flow of waste in the oven by the selective closing of one damper and the opening of the other damper or vice versa.

Claim 3

An incinerator according to claim 1 including a set of wheels mounted on said frame to provide a mobile incinerator.

Claim 4

An incinerator for domestic and industrial waste comprising a rotary oven of generally tubular truncated conical shape and open at both ends, a stationary pre-combustion chamber connected to one end of said oven, a stationary postcombustion chamber connected to the other end of said oven, burners associated with each of said chambers, each of said chambers communicating with said oven and having a plurality of apertures therein, said oven having a plurality of apertures through its sidewall, a sleeve surrounding and spaced from the outer periphery of said oven in the area containing said openings to provide a circumferential chamber with which said openings communicate, ducts connecting the openings in said pre-combustion and post-combustion chambers with said circumferential chamber, valve means connected to said ducts for controling the introduction of combustion gases into said oven through said circumferential chamber in such a manner that the combustion gas penetrating into the waste in the oven is either blown in to accelerate the combustion of the waste and gases emanating therefrom, or it is completely or partially stopped to slow down the combustion of said waste.

Claim 5

An incinerator for domestic and industrial waste comprising a rotary oven of generally tubular truncated conical shape and open at both ends, a stationary pre-combustion chamber connected to one end of said oven, a stationary postcombustion chamber connected to the other end of said oven, burners associated with each of said chambers, each of said chambers communicating with said oven and having a plurality of apertures therein, said oven having a plurality of apertures through its sidewall, a sleeve surrounding and spaced from the outer periphery of said oven in the area containing said openings to provide a circumferential chamber with which said openings communicate, ducts connecting the openings in said pre-combustion and post-combustion chambers with said circumferential chamber, valve means connected to said ducts for controling the introduction of combustion gases into said oven through said circumferential chamber in such a manner that the combustion gas penetrating into the waste in the oven is either blown in to accelerate the combustion of the waste and gases emanating therefrom, or it is completely or partially stopped to slow down the combustion of said waste.

Claim 6

An incinerator for domestic and industrial waste including a rotary oven of generally tubular truncated conical shape comprising a wall of refractory material, a sheet-metal sleeve surrounding said wall and spaced therefrom, means driving said oven in continuous or alternating rotation, said wall of refractory material including a plurality of sector shaped elements assembled side by side so as to form truncated-conical rings, each of said elements having grooves in the end and side edges thereof which are aligned with related grooves in adjacent elements when said elements are assembled and connecting means cast in said grooves to interlock said elements and rings.

Claim 7

An incinerator for domestic and industrial waste including a rotary oven of generally tubular truncated conical shape comprising a wall of refractory material, a sheet-metal sleeve surrounding said wall and spaced therefrom, means driving said oven in continuous or alternating rotation, said wall of refractory material including a plurality of sector shaped elements assembled side by side so as to form truncated-conical rings, each of said elements having grooves in the end and side edges thereof which are aligned with related grooves in adjacent elements when said elements are assembled and connecting means cast in said grooves to interlock said elements and rings.

Claim 8

An incinerator for domestic and industrial waste comprising a rotary oven between a stationary pre-combustion chamber and a stationary post-combustion chamber and communicating with each of said chambers, the waste being loaded into said pre-combustion chambers, a removable waste loading device, means attaching said loading device to said last mentioned chamber, said means comprising screw jacks hinged on opposite sides of said chamber and connected to related sides of said loading device.

Claim 9

An incinerator for domestic and industrial waste comprising a rotary oven between a stationary pre-combustion chamber and a stationary post-combustion chamber and communicating with each of said chambers, the waste being loaded into said pre-combustion chambers, a removable waste loading device, means attaching said loading device to said last mentioned chamber, said means comprising screw jacks hinged on opposite sides of said chamber and connected to related sides of said loading device.
