- Abstract
The solids circulation behaviour in a circulating fluidized bed with a concentric annular feeder (a‐CFB) was investigated, with a focus on the effect of the entrance structure design and gas flow rates in the riser and the annular region on the solids circulation rate. The pressure drop in the annular region was found to be strongly correlated to the entrance region configuration and solids circulation rate for a given type of particles. Based on a systematic experimental study of the riser bottom configuration and operating parameters on solids circulation rate of the a‐CFB, a new method was proposed for in‐situ monitoring solids circulation rate based on the measurement of pressure drop in the annular region of the a‐CFB.
