Abstract
A method of treating a particulate material in a fluidized bed reactor includes supplying a particulate material into a working space above at least one zone which is characterized by reduced passage of a fluidizing gas. A fluidizing bed reactor is designed so that its means for supplying a particulate material is arranged above at least one zone of the reduced passage of the fluidizing gas. The passage of the fluidizing gas in this zone can be completely prevented. Jalousie-shaped inserts are arranged above edges of the zone and have inclined surfaces.
