Abstract
Abstract A gateless incinerator having an inlet for air required for combustion of organic matter therein that includes a plurality of vertically spaced ports. The ports are positioned at the lower portion of the incinerator in vertically spaced relation to have an air supply port that lies constantly adjacent the underside of the charge of organic matter placed therein. When an accumulation of ash from the burning organic matter covers an inlet port, air flowing therethrough is curtailed whereby conditions that promote oxidation of the carbon in the ash and vaporization of other residual material therein are terminated. Inasmuch as combustion is terminated in the ash it is permitted to cool thereby eliminating the volatilization of inorganic elements in the ash and the production of haze forming gases.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
150 words
An incinerator for the incineration of organic matter in a charge of waste material that contains organic and inorganic values comprising in combination a combustion chamber including a loading opening for the admission of waste material therein and an outlet opening for the exhaust of pyrolyzed gas therefrom, means for the collection of ash at the bottom of the combustion chamber, a source of air for combustion, means supplying combustion air from said source to the combustion chamber including a plurality of vertically spaced passageways at the lower portion of the combustion chamber, and means controlling air flow through each of said passageways whereby the flow of air may be curtailed through the passageways that lie subjacent the level of ashes at the bottom of the combustion chamber to thereby terminate combustion of residual matter in the ash and the volatilization of inorganic matter that produces a haze forming gas.
Claim 2
Dependent Claim
150 words
An incinerator for the incineration of organic matter in a charge of waste material that contains organic and inorganic values comprising in combination a combustion chamber including a loading opening for the admission of waste material therein and an outlet opening for the exhaust of pyrolyzed gas therefrom, means for the collection of ash at the bottom of the combustion chamber, a source of air for combustion, means supplying combustion air from said source to the combustion chamber including a plurality of vertically spaced passageways at the lower portion of the combustion chamber, and means controlling air flow through each of said passageways whereby the flow of air may be curtailed through the passageways that lie subjacent the level of ashes at the bottom of the combustion chamber to thereby terminate combustion of residual matter in the ash and the volatilization of inorganic matter that produces a haze forming gas.
Claim 3
Dependent Claim
32 words
An incinerator for the incineration of waste material as defined in claim 1 wherein the vertically spaced inlet passageways are of equal size to permit a constant rate of air flow therethrough.
Claim 4
Dependent Claim
26 words
An incinerator for the incineration of waste material as defined in claim 1 wherein the vertically spaced inlet passageways extend horizontally between ends of the incinerator.
Claim 5
Dependent Claim
34 words
An incinerator for the incineration of waste material as defined in claim 1 wherein the vertically spaced inlet passageways are formed with a series of horizontally spaced openings that exhaust into the combustion chamber.
Claim 6
Dependent Claim
133 words
An incinerator for the incineration of organic matter in a charge of waste material that contains organic and inorganic values comprising in combination a combustion chamber having a loading opening for the admission of waste material therein and an outlet opening for the exhaust of pyrolyzed gas therefrom, an afterburner adapted to receive exhaust gases from said outlet opening, a source of combustion air, means supplying the combustion air to the combustion chamber and to the afterburner, said means supplying combustion air to the combustion chamber, comprising duct means having a plurality of vertically spaced openings, and control means for the air flow through each of said openings whereby the flow of air therethrough may be limited to a predetermined opening to closely control the pyrolization of waste material in the combustion chamber.
Claim 7
Dependent Claim
133 words
An incinerator for the incineration of organic matter in a charge of waste material that contains organic and inorganic values comprising in combination a combustion chamber having a loading opening for the admission of waste material therein and an outlet opening for the exhaust of pyrolyzed gas therefrom, an afterburner adapted to receive exhaust gases from said outlet opening, a source of combustion air, means supplying the combustion air to the combustion chamber and to the afterburner, said means supplying combustion air to the combustion chamber, comprising duct means having a plurality of vertically spaced openings, and control means for the air flow through each of said openings whereby the flow of air therethrough may be limited to a predetermined opening to closely control the pyrolization of waste material in the combustion chamber.
Claim 8
Dependent Claim
36 words
An incinerator for the incineration of waste material as defined in claim 5 wherein said control means is responsive to a condition effected by the collection of residual matter at the bottom of the combustion chamber.
