Abstract
Abstract A waste material converter having a primary chamber for the pyrolysis of waste material and a secondary chamber for the combustion of pyrolyzed gas and airborne combustible matter that is generated in the primary combustion chamber. The secondary combustion chamber also serves as a high temperature slagging furnace for the reduction of solid residual wastes from the primary combustion chamber using heat of the pyrolyzed gas.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
Apparatus for the recycling of waste material having a pyrolyzing chamber for the gasification of waste material including an inlet for the waste and an outlet for the gas produced therefrom, an independent secondary chamber having an inlet for gas from the pyrolyzing chamber and an outlet for gases of combustion, means connecting the outlet of the pyrolyzing chamber to the inlet of the secondary chamber, means directing solid residues from the pyrolyzing chamber to the secondary chamber, and a burner in said secondary chamber that burns combustible gas produced in the pyrolyzing chamber to reduce the solid residue in the secondary chamber to a molten condition.
Claim 2
Dependent Claim
107 words
Apparatus for the recycling of waste material having a pyrolyzing chamber for the gasification of waste material including an inlet for the waste and an outlet for the gas produced therefrom, an independent secondary chamber having an inlet for gas from the pyrolyzing chamber and an outlet for gases of combustion, means connecting the outlet of the pyrolyzing chamber to the inlet of the secondary chamber, means directing solid residues from the pyrolyzing chamber to the secondary chamber, and a burner in said secondary chamber that burns combustible gas produced in the pyrolyzing chamber to reduce the solid residue in the secondary chamber to a molten condition.
Claim 3
Dependent Claim
45 words
Apparatus for the recycling of waste material as defined in claim 1 including an independent source of fuel and air connected to said burner in the secondary chamber, and means regulating the air and fuel to provide a range of temperature in the secondary chamber.
Claim 4
Dependent Claim
32 words
Apparatus for the recycling of waste material as defined in claim 2 wherein the range of temperature provided by the burner of the secondary chamber extends from 1,200* F. to 3,000* F.
Claim 5
Dependent Claim
44 words
Apparatus for the recycling of waste material as defined in claim 3 including an outlet for gases exhausting from the secondary chamber, and means for supplying a quantity of cool air to the gases exhausting from the secondary chamber sufficient to lower their temperature.
Claim 6
Dependent Claim
45 words
Apparatus for the recycling of general waste material as defined in claim 1 including an exhaust stack connected to the outlet of the secondary chamber, and a supply of air connected to said stack for cooling the hot gases that exhaust from the secondary chamber.
Claim 7
Dependent Claim
34 words
Apparatus for the recycling of general waste material as defined in claim 1 including means controlling air flow into said exhaust stack whereby the gases exhausting to the atmosphere do not exceed 2,000* F.
Claim 8
Dependent Claim
41 words
Apparatus for the recycling of general waste material as defined in claim 1 including an independent inlet to the secondary chamber for the addition of non-combustible material thereto, and an outlet to said chamber for the removal of molten slag therefrom.
