Reducing preheater exit temperatures for AF use

摘要

A cement plant in Jakarta, Indonesia, with a clinker capacity of 7800tpd planned the extensive use of alternative fuels (AFs) in the kiln. This resulted in excessive preheater exit temperatures up to 430° C and limited the fan capacity. Therefore, to maintain and enhance the production level at the plant, the cement producer required a gas cooling system before the fan that would reduce the exit temperature by 50 °C.
