Abstract: The effects of operating factors, such as spouting velocity, fluidizing velocity, pressure and particle size on solid circulating rate in a spouted–fluidized bed with draft tube were investigated. The experimental results showed that the spouting velocity was the most important factor. The solid circulating rate increased with increasing fluidizing velocity and pressure, and decreased with increasing mean particle diameter. Based on the experimental results, an empirical correlation of the solid circulating rate was established. This work is helpful to designing the carbide furnace in the second generation PFBC–CC system.

Key words: spouted–fluidized bed, draft tube, solid circulating rate, elevated pressure, carbide furnace
