DEVICE FOR DOSED INTRODUCTION OF FINE PARTICLE MATERIAL INTO A REACTOR VESSEL

摘要

An arrangement for the dosed introduction of fine-particulate material into a reactor vessel comprises a fluidized bed sluice, into which a material supply means enters from above and into which a gas duct feeding a fluidization gas runs in the lower end region thereof and which includes an overflow tube for conveying on the fine-particulate material. In order to introduce the fine-particulate material into the reactor vessel at specific zones, a plurality of independently connectable fluidized bed sluices are provided outside of the reactor vessel, the fluidized bed sluices having overflow tubes which project into the interior of the reactor vessel.
