Abstract: The jetting-fountain fluidized bed (JFFB) is a novel configuration for fluidized bed. It is basically a bubbling fluidized bed equipped with a spouted jet in the upper part of the bed. A part of gases is fed through the distributor to fluidize bed solids while the remaining part is fed through a vertical pipe creating a jet-fountain zone. A distinct feature of JFFB different from previous spouted bed configurations is that the jet spout height is independent of the bed height. This feature makes the design more flexible and the flow regimes more extendable. The JFFB is characterized by excellent gas–solids contact that is expected to result in high heat and mass transfer both in bed and freeboard zones.
