The system includes a duct, a source for generating compressed air, and an air injection header joined with the source and joined with the duct via one or more holes in the duct. The air injection header is adapted to inject compressed air from the source to the areas of the duct prone to dust build-up. The air injection header includes a sub-header joined with a plurality of injection lances. Each of the plurality of injection lances has an end nozzle. The end nozzle may have a mushroom cap or an angled end configuration to direct air in a particular direction.
