Abstract
Cooling of a gas-permeable loose material having highly temperature-dependent coefficient of thermal conductivity is performed in a shaft-shaped chamber with use of a gaseous cooling medium so that the loose material is fed from above downwardly in a counter stream against a stream of the gaseous medium supplied from below upwardly. The stream of the gaseous medium is subdivided into two partial streams, and one of the partial streams is supplied into the lower part of the chamber, whereas the other of the partial streams is supplied into a region in which the loose material has at least a temperature above which the coefficient of thermal conductivity of the loose material in dependence upon the temperature greatly increases.
