Abstract
Apparatus meters solid present in the gas/solid stream from 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 metering apparatus has a discharge pipe with a gas injection nozzle for establishing a time-constant, emerging mass flow and for establishing the homogeneity of the emerging gas/solid stream. The pipe and nozzle are coordinated with an outlet orifice of the bed apparatus, and/or at least one device for influencing the prehomogenization.
