Abstract
A vertical reaction vessel has a plurality of funnel-like constrictions dividing the vessel into individual chambers, at least one inlet for introducing fine material into the top of the uppermost of such chambers, and an opening at the bottom of the lowermost of such chambers for withdrawing heated fine material, and for introducing hot gas to be exhausted from the uppermost chamber. Guide elements for the fine material extend downward along the inner surface of at least one of the funnel-like constrictions.
