ABSTRACT Hot granular solids are cooled in a fluidized bed under a pressure from 2 to 50 bars. The fluidized bed is dis- posed in a cooling chamber, which is provided with an inlet for solids and an outlet far solids. The solids move in the fluidized bed mainly in a vertical direction from the inlet for solids to the outlet for solids. Fluidizing gas is intro- duced into the lower portion of the fluidized bed end heat is indirectly dissipated by cooling means, which are flown through by a cooling fluid. The cooling means extend over at least one-half of the height of the fluidized bed. The flui- dized bed has a bed height from 2 to 20 meters and a ratio of bed height to average bed width from 2:1 to 10:1. The diffe- rence between the temperatures of the solids in the lower and upper portion of the fluidized bed is at least 80°C. The fluidized bed has preferably a bed height of at least 3 meters.
