Abstract
Abstract A high-temperature furnace is disclosed which is equipped with several stages in which a rotating magnetic field rotates the magnetic components of the waste material to be incinerated. Gas jets protect the combustion chambers from excessive heat and assist in the tumbling of nonmagnetic materials in the combustion chambers. Each combustion chamber is further equipped with a liquid jacket for additional cooling. The fuel injected into the combustion chambers consists in part of finely divided oxidizable metal dispersed in a liquid. Control of all components of this waste disposal system rests in a computer which monitors the overall operation of the system and adjusts the controls for optimum operating efficiency.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
160 words
A solid waste disposal system comprising: a plurality of combustion chambers each having an axis, said combustion chambers being axially aligned along a line tilted to the horizontal; means to introduce solid waste into the first of said plurality of combustion chambers, said solid waste travelling from the first of said plurality combustion chambers to the next said chamber in line under the influence of gravity after a predetermined period of time and then travelling to the next of said chambers in line under the influence of gravity after a second predetermined period of time and so forth until said solid waste is housed in the last of said plurality of chambers; means associated with each of said combustion chambers for providing a rotating magnetic field to rotate the magnetic components in said solid waste; means to provide combustion in each of said chambers; and means to discharge combusted waste products from the last of said plurality of combustion chambers.
Claim 2
Dependent Claim
160 words
A solid waste disposal system comprising: a plurality of combustion chambers each having an axis, said combustion chambers being axially aligned along a line tilted to the horizontal; means to introduce solid waste into the first of said plurality of combustion chambers, said solid waste travelling from the first of said plurality combustion chambers to the next said chamber in line under the influence of gravity after a predetermined period of time and then travelling to the next of said chambers in line under the influence of gravity after a second predetermined period of time and so forth until said solid waste is housed in the last of said plurality of chambers; means associated with each of said combustion chambers for providing a rotating magnetic field to rotate the magnetic components in said solid waste; means to provide combustion in each of said chambers; and means to discharge combusted waste products from the last of said plurality of combustion chambers.
