Abstract
Abstract Burner heads for incinerating waste combustible gas from refineries and the like are disclosed, for use in flare gas burners wherein a plurality of waste gas burner heads are provided for simultaneous operation at the same level, which heads may be utilized in a ground flare, or utilized in an elevated version of a ground flare burner. The burner heads provide for efficient admixture of gas with air, do not plug up, have a low pressure drop, burn both low and high BTU gases, and provide for smokeless combustion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
Combustion apparatus for use in a flare gas burner for combustible waste gas comprising a combustion chamber open at the top and having its lower margin elevated for entry of air for combustion, a combustible waste gas supply connection, means at the bottom of said combustion chamber in communication with said supply connection comprising a plurality of spaced burner heads spaced above said waste gas supply connection and spaced above the lower margin of said combustion chamber, each of said burner heads having a plurality of outwardly extending tilted vanes with elongated slots for gas delivery, and said tilted vanes of said spaced burner heads being disposed to provide a plurality of spaced vortex mixing patterns within said combustion chamber and to which air for combustion is freely accessible from the space below said lower margin.
Claim 2
Dependent Claim
136 words
Combustion apparatus for use in a flare gas burner for combustible waste gas comprising a combustion chamber open at the top and having its lower margin elevated for entry of air for combustion, a combustible waste gas supply connection, means at the bottom of said combustion chamber in communication with said supply connection comprising a plurality of spaced burner heads spaced above said waste gas supply connection and spaced above the lower margin of said combustion chamber, each of said burner heads having a plurality of outwardly extending tilted vanes with elongated slots for gas delivery, and said tilted vanes of said spaced burner heads being disposed to provide a plurality of spaced vortex mixing patterns within said combustion chamber and to which air for combustion is freely accessible from the space below said lower margin.
Claim 3
Dependent Claim
135 words
Combustion apparatus for use in a flare gas burner for combustible waste gas comprising a combustion chamber open at the top and having its lower margin elevated for entry of air for combustion, a combustible waste gas supply connection, means at the botton of said combustion chamber in communication with said supply connection comprising a plurality of open spaced burner heads spaced above said waste gas supply connection and each having a plurality of outwardly extending tilted vanes with elongated slots for gas delivery, and said tilted vanes of said spaced burner heads being disposed to provide a plurality of spaced vortex mixing patterns within said combustion chamber, said vanes having attachments thereon with diverting members disposed outwardly thereof and having elongated side slots extending along and in communication with said slots in said vanes.
Claim 4
Dependent Claim
135 words
Combustion apparatus for use in a flare gas burner for combustible waste gas comprising a combustion chamber open at the top and having its lower margin elevated for entry of air for combustion, a combustible waste gas supply connection, means at the botton of said combustion chamber in communication with said supply connection comprising a plurality of open spaced burner heads spaced above said waste gas supply connection and each having a plurality of outwardly extending tilted vanes with elongated slots for gas delivery, and said tilted vanes of said spaced burner heads being disposed to provide a plurality of spaced vortex mixing patterns within said combustion chamber, said vanes having attachments thereon with diverting members disposed outwardly thereof and having elongated side slots extending along and in communication with said slots in said vanes.
