Abstract
The invention relates to a shaft-type countercurrent heat exchanger in which the uppermost part of the shaft is formed by a turbulence chamber which communicates with the underlying countercurrent chamber of the shaft through a central material outlet and several gas pipes opening tangentially into the turbulence chamber, thereby improving the thermal efficiency of the heat exchanger.
