Abstract A flare stack gas burner for waste combustible gases at both low and high pressure from oil refineries and the like is disclosed with separate delivery systems for the combustion gases, which includes a stack with a top mounted burner tip, the stack carrying a centrally disposed high pressure gas supply pipe closed at the top and with a plurality of outwardly extending vanes with gas delivery slots, the tops of the vanes being angularly disposed in a plane with respect to radial lines through the center of the stack for a swirling action of the burning gas. A low pressure gas supply pipe is mounted to and extends upwardly along the outside of the stack to a ring manifold mounted to the burner tip with a plurality of inwardly extending vanes, with gas delivery slots, the vanes being interposed between the outwardly extending vanes and angularly disposed in the same direction. Air at variable controlled low pressure is delivered into the stack at the bottom and moves upwardly between the vanes for smokeless burning. Optional fluidic seals can be provided in both the low and high pressure gas supply lines to prevent flashback. Ignitors and pilots are provided exteriorly of said stack.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
208 words
A flare stack gas burner for combustible waste gas having an outer stack with a burner tip portion at its upper end comprising a combustible high pressure waste gas supply pipe extending upwardly within said stack, a plurality of outwardly extending hollow vanes at the upper end of the burner tip portion of said supply pipe with spaces therebetween and having upwardly facing gas delivery openings connected to said gas supply pipe for discharge of said high pressure waste gas for combustion, a combustible low pressure waste gas supply pipe extending upwardly with respect to said stack, a hollow manifold mounted to said burner tip portion to which said low pressure gas supply pipe is connected, a plurality of inwardly extending hollow vanes contiguous to said first mentioned hollow vanes attached to said manifold with spaces therebetween and having upwardly facing gas delivery openings communicating with said manifold for discharge of said low pressure waste gas for combustion, means associated with said stack pipe for supplying air therethrough for delivery of air through the spaces between said vanes for combustion of waste gas delivered through said supply pipes, said vanes being disposed to impart a swirling action to the gas delivered therefrom and to the air delivered therebetween.
Claim 2
Dependent Claim
208 words
A flare stack gas burner for combustible waste gas having an outer stack with a burner tip portion at its upper end comprising a combustible high pressure waste gas supply pipe extending upwardly within said stack, a plurality of outwardly extending hollow vanes at the upper end of the burner tip portion of said supply pipe with spaces therebetween and having upwardly facing gas delivery openings connected to said gas supply pipe for discharge of said high pressure waste gas for combustion, a combustible low pressure waste gas supply pipe extending upwardly with respect to said stack, a hollow manifold mounted to said burner tip portion to which said low pressure gas supply pipe is connected, a plurality of inwardly extending hollow vanes contiguous to said first mentioned hollow vanes attached to said manifold with spaces therebetween and having upwardly facing gas delivery openings communicating with said manifold for discharge of said low pressure waste gas for combustion, means associated with said stack pipe for supplying air therethrough for delivery of air through the spaces between said vanes for combustion of waste gas delivered through said supply pipes, said vanes being disposed to impart a swirling action to the gas delivered therefrom and to the air delivered therebetween.
Claim 3
Dependent Claim
