ABSTRACT:
The gas jet plug assembly is adapted for introducing gas into a pipe and includes: a gas jet plug; a sleeve; and a holding cap. The sleeve is mounted on an outside surface of a wall of the pipe around the periphery of a hole in which the plug is disposed. The plug is supported by the sleeve and held in place within the sleeve by the holding cap. The plug has an interior bore which is substantially straight and disposed substantially parallel to the longitudinal axis of the plug. The plug has one or more gas jet nozzles which communicate between the bore and the interior of the pipe. The plug has an exterior member, such as a shoulder, disposed around at least a portion of the outer periphery of the plug. The sleeve has an interior bore through which at least a portion of the plug extends. The interior bore of the sleeve has an interior member, such as a shoulder. The interior member of the sleeve is adapted to cooperate with the exterior member of the plug to position the surface of the downstream end of the plug in precise alignment with the adjacent interior surface of the pipe. Means are provided to position the gas jet nozzles of the plug to point in the direction of movement of granular particles within the pipe.
