Abstract
A method of performing a treatment of a dust cloud includes the successive steps of generating the dust cloud from a gas and from solid particles, passing the dust cloud through a reaction zone, separating the dust cloud into its components in a separator, and reintroducing at least one part of at least one component into the dust cloud. There is further formed a solids column into which fresh or recirculated solid particles are introduced. The solids column which seals the gas used for generating the dust cloud from the separator, is height-adjustable for controlling the concentration of solids in the dust cloud formed from the solid particles constituting the solids column.
