The advantages of a fluid-bed furnace are chemistry-based. The particles are exposed completely to the gas that they are being fluidized in. Reactions that are occurring can propagate at a slightly enhanced rate because there are no gases, such as carbon monoxide, retarding the reaction. These particles move very quickly from the bed, rather than having a static bed condition. It helps reduce agglomeration, which can occur when particles in contact continually agitate the particles in a controlled manner. The negatives of the system are that operations are in atmospheric conditions or higher. Higher pressures are also possible, but difficult because the particles are so small.
