ABSTRACT:
An improved cyclone trickle valve assembly is provided, which includes a cyclone that has a vertical dipleg having an inner cylindrical wall. An annular ring is horizontally disposed in the dipleg and is joined to the inner wall. Importantly, a pair of cooperably clamshell doors are positioned within the dipleg and are pivotably supported by the annular ring for mutual opposite swinging movement between a closed position wherein the doors adjoin along a midline, and an open position wherein the doors swing outwardly with respect to the midline, thereby substantially preventing gases from progressing upwardly through the dipleg above the annular ring when the clamshell doors are in a closed position and permitting solids to progress downwardly through the dipleg when the doors are in an open position.
