Abstract

A method for metering solid present in the gas/solid stream of a fluidized-bed apparatus, in which gas and solid are present as a prehomogenized, free-flowing mixture in a fluidized bed and in which at least one outlet orifice for removal of the gas/solid stream is provided in an outflow pipe. The method provides for feeding a particulate phase and a gas phase, homogenizing the two phases in a fluidized bed, discharging the two-phase flow via a discharge pipe and injecting gas into the discharge pipe.
