    • A particulate matter conveyor includes an elongate outer tube having an inlet end and an outlet end, an inner tube disposed within the outer tube to extend substantially the length thereof and formed of a resilient helically wound wire spring, with the inner tube having a proximal end disposed generally adjacent to the inlet end of the outer tube for receiving gas supplied under pressure and a distal end disposed generally adjacent to the outlet end of the outer tube, and an opening formed near the inlet end of the outer tube through which particulate matter may be introduced into the interior of the outer tube. Gas supplied to the inner tube escapes from between the coils of the wire spring in a spiral-like fashion to carry particulate matter along the inside of the outer tube to the outlet end therof.
