This chapter provides a comprehensive overview of circulating fluidized beds (CFBs), a technology that has been utilized since the mid-1970s with roots dating back to the 1940s. The objective is to analyze the characteristics and operational mechanisms of CFBs, emphasizing their efficiency in separating particles from the carrying fluid in gas–solid systems. The methodology involves discussing the essential operating variables, including superficial gas velocity and particle flux, while outlining various geometric configurations employed in CFB constructions. Key findings reveal that CFBs operate under high superficial gas velocities, typically between 2 to 12 m/s, facilitating dynamic particle circulation within a recirculation loop that maximizes contact between phases. The chapter notes the relevance of CFBs in both conventional gas–solid operations and emerging applications such as liquid–solid and three-phase systems. Overall, this work contributes to the foundational understanding of CFB dynamics and lays the groundwork for advancements in reactor design and industrial applications.
