Abstract: Cyclone dedusters are used in diverse contexts due to their many advantages over other primary collectors. The post cyclone (PoC) is a new secondary collector situated at the top of a conventional reverse flow cyclone, which utilizes the residual swirl available at the gas outlet (vortex finder) of the cyclone to capture a certain fraction of the escaped dust. In this paper, one design of PoC is tested where the particles are collected in a bleed flow drawn from the PoC. Subsequent to the particle separation, the lean bleed flow is recycled back to the inlet of the cyclone. The experiments conducted at different bleed flow rates and inlet velocity indicate an increase in overall efficiency of cyclone by 6% in average, and reduction in emission from the vortex finder by 5-9%.
