Circulated fluidized bed
Bed types can be coarsely classified by their flow behavior, including: • Stationary or Particulate fluidized bed is the classical approach where the gas at low velocities is used and fluidization of the solids is relatively stationary, with some fine particles being entrained. • In Bubbling fluidized (also called Aggregative fluidized bed), the velocities of the fluid is high, thus forming of two separate phases – continuous phase (dense or emulsion phase) and a discontin… WebJan 28, 2015 · The circulating fluidized bed (CFB) is a clean process with the ability to achieve lower emission of pollutants.
