Vorrichtung zur Verwendung für ein Wirbelschichtfeststoffsystem

摘要

A fluidized bed reactor (10) includes a plurality of nozzles (28) for introducing a fluidizing gas wherein at least some of the nozzles (28) are provided with a plate (32) proximate to the nozzle inlet which redirects the flow of the fluidizing gas to the nozzles. By providing a plate (32) at the inlet of the nozzles (28) the following is accomplished. Even flow distribution of the fluidizing gas through the nozzle is achieved. The pressure drop through the nozzle remains relatively high thus insuring good fluidizing gas acceleration which eliminates the adherence of the fines to the interior surface of the nozzle.
