Abstract

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
133 words
An incinerator comprising means defining a substantially vertical substantially cylindrical combustion chamber having a sidewall and bottom, said sidewall being formed of metal and the lower portion of said sidewall from the bottom of said chamber to a predetermined height of said chamber being lined with refractory material, a supply pipe secured at the lower end of said combustion chamber for introducing air and fuel substantially tangentially of the combustion chamber at the bottom thereof, a top for said combustion chamber, and a cylindrical stack secured in said top and extending into said combustion chamber substantially coaxial therewith and spaced from said sidewall of said chamber, the inner surface of said sidewall being substantially free from obstructions throughout its height which would impede or deflect the flow of air passing through said chamber.
Claim 2
Dependent Claim
133 words
An incinerator comprising means defining a substantially vertical substantially cylindrical combustion chamber having a sidewall and bottom, said sidewall being formed of metal and the lower portion of said sidewall from the bottom of said chamber to a predetermined height of said chamber being lined with refractory material, a supply pipe secured at the lower end of said combustion chamber for introducing air and fuel substantially tangentially of the combustion chamber at the bottom thereof, a top for said combustion chamber, and a cylindrical stack secured in said top and extending into said combustion chamber substantially coaxial therewith and spaced from said sidewall of said chamber, the inner surface of said sidewall being substantially free from obstructions throughout its height which would impede or deflect the flow of air passing through said chamber.
Claim 3
Dependent Claim
29 words
An incinerator as defined in claim 1 including means for maintaining within the incinerator a temperature not less than about 1,200* F. and not more than about 1,600* F.
Claim 4
Dependent Claim
32 words
An incinerator as defined in claim 1 including means for maintaining the air entering from said supply pipe at a velocity sufficient to retain particulate combustible material to be burned in suspension.
Claim 5
Dependent Claim
139 words
An incinerator comprising means defining a substantially vertical substantially cylindrical combustion chamber having a sidewall and substantially flat bottom, the sidewall of said combustion chamber being formed of stainless steel or the like and the lower portion of said wall from the bottom of said combustion chamber to about one-third its height being lined with refractory material, a supply pipe secured at the lower end of said combustion chamber for introducing air and fuel substantially tangentially of the combustion chamber at the bottom thereof, a top for said combustion chamber, and a cylindrical stack secured in said top and extending into said combustion chamber substantially coaxial therewith and spaced from said sidewall, the inner surface of said sidewall being substantially free from obstructions throughout its height which would impede or deflect the flow of air passing through said chamber.
Claim 6
Dependent Claim
139 words
An incinerator comprising means defining a substantially vertical substantially cylindrical combustion chamber having a sidewall and substantially flat bottom, the sidewall of said combustion chamber being formed of stainless steel or the like and the lower portion of said wall from the bottom of said combustion chamber to about one-third its height being lined with refractory material, a supply pipe secured at the lower end of said combustion chamber for introducing air and fuel substantially tangentially of the combustion chamber at the bottom thereof, a top for said combustion chamber, and a cylindrical stack secured in said top and extending into said combustion chamber substantially coaxial therewith and spaced from said sidewall, the inner surface of said sidewall being substantially free from obstructions throughout its height which would impede or deflect the flow of air passing through said chamber.
Claim 7
Dependent Claim
32 words
An incinerator as defined in claim 4 including an abrasion resistant shield on the surface of said refractory material from the supply pipe around a portion of the interior of said incinerator.
