홈페이지논문 초록 (Abstract)
Solid circulation characteristics of an inclined-type lower loop seal and a vertical-type lower loop seal were investigated in a circulating fluidized bed system that consists of two bubbling fluidized beds and one fast fluidized bed with oxygen carrier particles (OCN-A, Geldart group B) as bed materials. The results were compared with those of a previous experiment that used a CO2 absorbent (P-78, Geldart group A). Stable and continuous solid circulation was achieved at a lower gas flow rate with the inclined-type lower loop seal than the vertical-type lower loop seal, and the volume based solid circulation rate showed similar values at a given riser flow rate regardless of the lower loop seal types and particles used in this study.
