Abstract
An improved flare burner for burning combustible gases in petroleum and petrochemical installations. A cylindrical shell has a closed bottom and an open top. A central opening in the bottom is connectable to a source of the gas to be burned. A plurality of linear steam/gas tubes is disposed within the shell, each tube extending to the open end of the shell and also extending through the shell bottom. A lower steam distribution sub-assembly below the shell bottom includes individual steam jets adjacent the ends of the tubes for educting air to the upper end of the tube. A pilot gas sub-assembly for igniting the flare gas is disposed within the shell. Gas to be burned is passed into the interior of the shell through the bottom opening and moves to the open end. Steam injected into the steam/air tubes educts air, and air and steam exit the tubes and mix with the gas to create a combustible mixture. The pilot light assembly provides an open flame which ignites the mixture. The upper end of the shell is reinforced by a rolled collar. An upper steam distribution subassembly within the collar includes a manifold and jets extending beyond the collar to provide additional air and steam for …
