Abstract
Abstract A system for disposing of combustible waste by an apparatus which may be vehicle mounted for movement over the terrain to places where combustible waste and refuse is located and the material burned without the necessity of transporting the raw waste and refuse many miles to an incinerator,land fill, or dump. The apparatus is vehicle mounted and has a crusher and chopper associated with a blower to reduce the waste and refuse to a burnable mass which is directed into a perforate receptacle within a combustion chamber, and, after igniting with an auxiliary fuel, the unburned gases are withdrawn from the combustion chamber and directed through burners to sustain combustion by burning the products of combustion which have not been fully consumed, which products of combustion are condensed to remove oils and tars and the gas therefrom is directed back into the combustion chamber to sustain combustion and to nullify the odoriferous gases. The residual tars, oils, and condensed liquids are removed from the condenser tanks from time to time.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
146 words
A method of reducing combustible waste and refuse to ash, liquid and flammable gas, which includes; a. directing combustible waste and refuse into a chopper and shredder, b. directing the chopped and shredded waste and refuse through a conduit into a perforate combustion chamber until the chamber is charged to a predetermined capacity, c. providing burners in the combustion chamber, 1. providing a conduit between the combustion chamber and the burner, d. igniting the refuse in the combustion chamber, e. directing flammable gas to the burner within the combustion chamber to promote and sustain combustion therein, f. discharging ash from the combustion chamber, g. providing at least one condenser tank, 1. condensing a portion of the gas into a liquid within said condenser tank, and 2. maintaining the liquid level within the condenser tank above the discharge end of the conduit leading from the combustion chamber.
Claim 2
Independent Claim
146 words
A method of reducing combustible waste and refuse to ash, liquid and flammable gas, which includes; a. directing combustible waste and refuse into a chopper and shredder, b. directing the chopped and shredded waste and refuse through a conduit into a perforate combustion chamber until the chamber is charged to a predetermined capacity, c. providing burners in the combustion chamber, 1. providing a conduit between the combustion chamber and the burner, d. igniting the refuse in the combustion chamber, e. directing flammable gas to the burner within the combustion chamber to promote and sustain combustion therein, f. discharging ash from the combustion chamber, g. providing at least one condenser tank, 1. condensing a portion of the gas into a liquid within said condenser tank, and 2. maintaining the liquid level within the condenser tank above the discharge end of the conduit leading from the combustion chamber.
