ABSTRACT:
A suspension of a powdery substance and a reaction gas is formed by allowing the powdery substance to fall as an annular flow into a reaction space, feeding the reaction gas downwardly to encircle the annular flow of powdery substance, the kinetic energy of the annular flow of descending powdery substance being utilized towards its gradual spreading to the sides with the aid of a sliding surface disposed within the reaction space, so that the flow of powdery substance which has been spread to be laterally directed will meet the reaction gas flow substantially at right angles in the reaction space.
