ABSTRACT
Cement plant operators again and again raise the question as to what possibilities there are for utilizing the waste heat from their kilns. The question becomes particularly important in cases where the scope for the conventional (and thermally very advantageous) utilization of this heat for drying of raw material, coal or slag does not exist. The heat quantities, contained in the waste gases are relatively large and constitute the major loss items in the heat balance of the burning process. This is true also for plants where considerable
amounts of bypass gas are extracted at the kiln inlet (feed end) because the gas temperature in this part of the system is particularly high.
