PROCESS AND INSTALLATIONS FOR TRANSFERRING HEAT AND THEIR APPLICATIONS FOR THE TREATMENT OF RAW CEMENT

摘要

The present invention is directed to a process for transferring heat between two gases having different temperatures through the intermediary of a solid heat-carrier, which process may be possibly applied to the treatment of a raw cement. In said process a powderous granular solid material is employed as the solid heat-carrier, the gases circulating in two different cascades comprising batteries of cyclones and said heat-carrier is used to recover at least a part of the heat carried along by the hot fumes issuing from a clinkerisation furnace.
