Abstract:
In a process for continuously conveying granular solids from a first zone with a pressure of 4 to 16 bar through a descending line and via an ascending line to a second zone with a pressure which is lower than in the first zone by 3 to 15 bar, by means of a gaseous medium, the improvement which comprisesintroducing gaseous medium through an upwardly directed conveying nozzle into said ascending line substantially at a point at which the descending line opens into the ascending line to entrain solids descending in said descending line upwardly in said ascending line; and maintaining a solids weight in the ascending line at 0.3 to 0.8 times a bulk weight of the solids.
