Garbage disposal system

Claim 2

In a method of disposing of refuse such as garbage including vegetable matter and articles made of rubber, plastic, metal, glass, and the like, comprising the steps of: reducing the refuse to be incinerated to small particles, providing an incinerator with fire-resistant walls, conveying the reduced refuse to said incinerator, firing said incinerator to heat the fire-resistant walls thereof to a high temperature of about 2700* F. at which the burnable part of said refuse supports combustion, producing a whirling, cyclonic motion in the atmosphere of hot gases in the incinerator, burning said small, reduced particles of refuse by feeding said refuse into said whirling hot atmosphere of said incinerator so that said refuse is directed toward the walls of said incinerator which have been heated to said high temperature and said refuse reduced by complete combustion of the combustible part thereof and the metal and glass are heated to form a molten slag, and removing the molten slag constituents of said refuse from said incinerator as it flows from the bottom thereof.

Claim 3

In a method of disposing of refuse such as garbage including vegetable matter and articles made of rubber, plastic, metal, glass, and the like, comprising the steps of: reducing the refuse to be incinerated to small particles, storing said reduced refuse in a storage bin, providing an incinerator with fire-resistant walls, conveying the refuse to said incinerator from said storage bin at a predetermined rate, firing said incinerator to heat the fire-resistant walls thereof to a high temperature of about 2700* F. at which the burnable part of said refuse supports combustion, burning said small, reduced particles of combustible refuse in said incinerator while said particles are floating past said high temperature walls, controlling the feeding of said refuse from said storage bin to maintain the temperature of the fire-resistant walls in the burning zone of said incinerator at a level such that a substantial portion of the ash from said burning and noncombustible constituents of said refuse form a molten slag which flows out of the bottom of said incinerator.

Claim 4

In a method of disposing of refuse such as garbage including vegetable matter and articles made of rubber, plastic, metal, glass, and the like, comprising the steps of: reducing the refuse to be incinerated to small particles, storing said reduced refuse in a storage bin, providing an incinerator with fire-resistant walls, conveying the refuse to said incinerator from said storage bin at a predetermined rate, firing said incinerator to heat the fire-resistant walls thereof to a high temperature of about 2700* F. at which the burnable part of said refuse supports combustion, burning said small, reduced particles of combustible refuse in said incinerator while said particles are floating past said high temperature walls, controlling the feeding of said refuse from said storage bin to maintain the temperature of the fire-resistant walls in the burning zone of said incinerator at a level such that a substantial portion of the ash from said burning and noncombustible constituents of said refuse form a molten slag which flows out of the bottom of said incinerator.

Claim 7

In apparatus for disposing of refuse such as garbage including vegetable matter and articles made of rubber, plastic, metal, glass, and the like, the combination comprising; means for reducing the refuse to small particles; an incinerator comprising an elongated tubuLar member having a lining of fire-resistant material, said incinerator having a burning zone with burners in the side thereof heating the fire-resistant lining to a high temperature, a wall separating said high temperature burning zone from a further zone of said incinerator, said wall having an opening therethrough connecting said burning zone to said further zone, means for feeding said small particles into said burning zone of said incinerator at a predetermined rate; means feeding air into said burning zone to impart rotational motion to said small particles of refuse in said incinerator, means feeding air in said opening in said wall and into said further zone, and means removing a substantial portion of the ash-forming and noncombustible constituents of said refuse from said incinerator in the form of molten slag.

Claim 8

In apparatus for disposing of refuse such as garbage including vegetable matter and articles made of rubber, plastic, metal, glass, and the like, the combination comprising; means for reducing the refuse to small particles; an incinerator comprising an elongated tubuLar member having a lining of fire-resistant material, said incinerator having a burning zone with burners in the side thereof heating the fire-resistant lining to a high temperature, a wall separating said high temperature burning zone from a further zone of said incinerator, said wall having an opening therethrough connecting said burning zone to said further zone, means for feeding said small particles into said burning zone of said incinerator at a predetermined rate; means feeding air into said burning zone to impart rotational motion to said small particles of refuse in said incinerator, means feeding air in said opening in said wall and into said further zone, and means removing a substantial portion of the ash-forming and noncombustible constituents of said refuse from said incinerator in the form of molten slag.
