Abstract
Abstract An incinerator includes a horizontal, rotatable hollow cylindrical body having an inlet at one end and an outlet at the other, vanes fixedly housed in the cylindrical body which, upon rotation of the cylindrical body, advances waste material toward the outlet, and a burner provided at the outlet side of the cylindrical body. The burner incinerates the waste material approaching the outlet to generate the combustion gas caused to pass upstream through the body thereby to dehydrate the waste material successively fed.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
176 words
In an incinerator comprising a cylindrical body having an outlet at one end, burner means provided at said outleT, an exhaust gas opening formed at the other end of said body for allowing a gas produced by said burner means to be exhausted through the interior of said body to the exterior thereof, means for rotatably supporting said body in a horizontal posture, means for rotating said body thus supported, blower means for sucking from said gas opening the gas from the interior of said body, and transfer means provided within said body to transfer toward said outlet waste material to be incinerated which is introduced from said other end, said incinerator including a cylindrical outer member disposed to encircle at a predetermined space an outer circumferential portion of said body which includes said outlet and at least an intermediary portion extending therefrom, and a helical screw provided in an inner wall of said outer member thereby to cause incinerated residues produced at said outlet to be transferred through said space toward an incinerated residue receiver.
