Abstract

Particle fluidization method in which particles are swirled up by a flow of a fluidizing gas to form a fluidized bed and pressure measurements are performed in or along the fluidized bed, and in which a parameter for the distribution of the measured values from these pressure measurements is determined and is used as a basis for regulating the flow rate of the stream of fluidizing gas.
