Abstract
A flare gas burner is described for the smokeless combustion of flare gas at low noise level with the flare gas delivered in a hollow whirling path for burning, ignited and burned with air and steam delivered interiorly and exteriorly, also in whirling paths intersecting or overlapping the delivered flare gas, additional steam being supplied at the outer margin of the outer air path, a diffuser being provided for the interior air and steam. The structure is also provided with a diode in the gas path to prevent flashback and with accoustically lined baffling to reduce noise.
Claims9
A flare gas burner for combustible waste gas comprising
- a vertical stack having a plurality of concentric pipes providing spaces for delivery to the upper end of combustible waste gas, steam and induced air for combustion beyond said upper end,
- an inner of said pipes being effective for air and steam delivery and having members for imparting a whirling motion to said air and steam,
- an intermediate of said pipes being effective for combustible gas delivery in surrounding relation to the air and steam from said inner pipe, and having members for imparting a whirling motion to said combustible gas,
- an outer of said pipes being effective for air and steam delivery,
- means associated with said outer pipe for converging said delivered air and steam toward said combustible waste gas stream, and
- additional steam supply members for directing steam into contact with the rising whirling stream of gas and air.
