Claim 1
Independent Claim
197 words
A flare stack gas burner for waste gas having an outer stack pipe with a burner tip portion at its upper end comprising a combustible low pressure waste gas delivery pipe extending upwardly within said stack pipe, a plurality of outwardly extending hollow vanes at the upper end of the burner tip portion of said delivery pipe with spaces therebetween and having upwardly facing gas delivery openings connected to said gas delivery pipe for discharge of said low pressure waste gas for burning, 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 pipe, said vanes being disposed to impart a swirling action to the gas delivered therefrom and to the air delivered therebetween, a combustible high pressure waste gas supply pipe exteriorly mounted with respect to said stack pipe, and a plurality of burner tips connected to said supply pipe and disposed beyond said burner tip portion of said stack pipe and directing said high pressure gas into the path of air from between said vanes, said burner tips being angularly inclined to swirl the gases passing there-through.

A flare stack gas burner for waste gas having an outer stack pipe with a burner tip portion at its upper end comprising a combustible low pressure waste gas delivery pipe extending upwardly within said stack pipe, a plurality of outwardly extending hollow vanes at the upper end of the burner tip portion of said delivery pipe with spaces therebetween and having upwardly facing gas delivery openings connected to said gas delivery pipe for discharge of said low pressure waste gas for burning, 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 pipe, said vanes being disposed to impart a swirling action to the gas delivered therefrom and to the air delivered therebetween, a combustible high pressure waste gas supply pipe exteriorly mounted with respect to said stack pipe, and a plurality of burner tips connected to said supply pipe and disposed beyond said burner tip portion of said stack pipe and directing said high pressure gas into the path of air from between said vanes, said burner tips being angularly inclined to swirl the gases passing there-through.
Claim 3
Dependent Claim
35 words
A flare stack gas burner as defined in claim 1 in which said high pressure waste gas supply pipe has a plurality of gas delivery pipes connected thereto on which said burner tips are carried.
Claim 4
Dependent Claim
23 words
A flare stack gas burner as defined in claim 2 in which said high pressure gas delivery pipes are inclined upwardly and angularly.
Claim 5
Dependent Claim
29 words
A flare stack gas burner as defined in claim 2 in which said gas deivery pipes are connected to a ring manifold to which said supply pipe is connected.
Claim 6
Dependent Claim
27 words
A flare stack burner as defined in claim 1 in which said low pressure waste gas delivery pipe has an end closure provided with flame retention ports.
Claim 7
Dependent Claim
16 words
A flare stack gas burner as defined in claim 1 in which said vanes are tilted.
Claim 8
Dependent Claim
32 words
A flare stack gas burner as defined in claim 1 in which said vanes have their slots disposed at an angle to a radius through the vertical longitudinal axis of said pipe.
