Abstract
Abstract A flare burner is described having a central combustion chamber which is open at the top for discharge of combustion products and elevated and open at the bottom for entrance of air for combustion, the central combustion chamber being surrounded by a cylindrical enclosure which is open at the top for the discharge of combustion products and elevated and open at the bottom for entrance of air for combustion in the central combustion chamber and which also provides a combustion chamber outside the central combustion chamber, a plurality of stages of combustion are provided one in the central combustion chamber and another in the cylindrical enclosure. An acoustical and wind shielding fence is provided outside the bottom of the cylindrical enclosure over which air passes to enter the bottom of the enclosure.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
279 words
A flare burner comprising a combustion chamber open at the top and at the bottom and having an upper margin and having a lower margin elevated above the ground for free entry of air at the bottom for supporting combustion, a wall surrounding said combustion chamber in spaced relation thereto and having its lower margin disposed intermediate the upper and lower margins of said combustion chamber for free entry of air for distribution to said combustion chamber and free and uniform entry of air interiorly of said wall and providing a combustion space above said combustion chamber, said wall extending upwardly above the top of said combustion chamber and being open at the top for the discharge of products of combustion, members including a burner nozzle for supplying waste combustible gas to the center of the lower part of said combustion chamber for combustion therein, a waste combustible gas supply manifold below said combustion chamber, members including a plurality of burner nozzles spaced around the upper margin of said combustion chamber, connected to said supply manifold and supplying waste combustible gas upwardly in the air entry space between said combustion chamber and said wall for combustion of said waste gas, a closed shielding wall member extending upwardly from the ground in surrounding relation to said wall and extending above the lower margin of said wall in spaced relation at its top for air entry over the top of said wall member and having a sound absorbing lining in sound absorbing relation to air delivered over said wall member and below said wall and to said combustion chamber, said shielding wall member preventing access of air except at its top.
Claim 2
Dependent Claim
279 words
A flare burner comprising a combustion chamber open at the top and at the bottom and having an upper margin and having a lower margin elevated above the ground for free entry of air at the bottom for supporting combustion, a wall surrounding said combustion chamber in spaced relation thereto and having its lower margin disposed intermediate the upper and lower margins of said combustion chamber for free entry of air for distribution to said combustion chamber and free and uniform entry of air interiorly of said wall and providing a combustion space above said combustion chamber, said wall extending upwardly above the top of said combustion chamber and being open at the top for the discharge of products of combustion, members including a burner nozzle for supplying waste combustible gas to the center of the lower part of said combustion chamber for combustion therein, a waste combustible gas supply manifold below said combustion chamber, members including a plurality of burner nozzles spaced around the upper margin of said combustion chamber, connected to said supply manifold and supplying waste combustible gas upwardly in the air entry space between said combustion chamber and said wall for combustion of said waste gas, a closed shielding wall member extending upwardly from the ground in surrounding relation to said wall and extending above the lower margin of said wall in spaced relation at its top for air entry over the top of said wall member and having a sound absorbing lining in sound absorbing relation to air delivered over said wall member and below said wall and to said combustion chamber, said shielding wall member preventing access of air except at its top.
Claim 3
Dependent Claim
69 words
A flare burner as defined in claim 1 in which control means responsive to the flow of the waste combustible gas is provided for said members for supplying waste combustible gas to the interior of said wall, and for said members for supplying waste combustible gas to said combustion chamber, and said control means selectively activates burner nozzles in said respective stages in response to available waste combustible gas.
