ABSTRACT:
A flare igniter assembly comprises an elongated tubing assembly including a first air supply conduit and a fuel gas supply line enclosed inside of said first air supply conduit. The fuel gas supply line is provided with a member having a venturi-type orifice through which fuel gas and intake air pass, the orifice effectes initial mixing of fuel gas and air. The fuel gas supply line further includes a combustion zone and means for transferring a fuel gas-air mixture downstream from the orifice to the combustion zone. The combustion zone includes an inspirating baffle member firmly positioned within the fuel gas supply line. The baffle member is so constructed as to effect further thorough mixing of the fuel-gas mixture as it passes therethrough prior to combustion of the mixture in combustion zone. The system also includes a terminal portion inclined at an angle relative to the remainder of the fuel gas supply line and a second air supply conduit extending parallel to the first air supply conduit and in juxtaposition therewith. The terminal portion of the fuel gas supply line extend into the second air supply conduit within which an ignited flame is burning. The second air supply conduit is provided with a port hole in the wall opposite to the terminal portion of the igniter and adjacent to a corresponding port hole in the flare stack near the upper end thereof when the assembly is in operative position such as to enable flame from the terminal portion to pass therethrough to ignite combustible waste gases passing through the flare stack.
