ABSTRACT:
An igniter assembly for igniting waste gas discharged from a stack mounts to the upper end of the stack. The igniter assembly has a nozzle with a cap on its upper end that extends radially outward from the nozzle. The nozzle is mounted parallel to the axis of the stack, with the cap being perpendicular. Ports extend downward and outward through the nozzle for discharging flame jets downward and outward. The cap overhangs the inner diameter of the stack a slight distance. The sparking device locates within an inner member and is supplied with a small bypass flow of gas. The sparking device ignites a flame within the nozzle, which in turn ignites the main flow of gas flowing through the housing of the igniter assembly.
