The fluid bed is a "bubbling bed" type combuster to minimize particle size reduction which would occur with a "circulating bed". The DARS fluidized bed is able to operate autogenously (with no auxiliary fuel) when firing liquors as low as 40% solids. The minimum solids content depends on

Fluidized Bed Article about Fluidized Bed by The Free

The change of a static bed to a fluidized bed occurs when the velocity of the fluidizing agent is such that the hydrodynamic pressure of the flux P balances the force of gravity G acting on the particles. Further increase of the velocity leads first to an initial expansion of the layer, with constant hydraulic drag, and when P > G the particles begin to separate from the layer.
