Assessing Cement Plant Thermal Performance

Thermal efficiency is important as fuel costs can make up 15 – 30 % of the total production costs of the cement. Mastering thermal efficiency for a given system requires close attention to the cooler and preheater operation and controlling the system stability. Paying attention to these points will deliver improved system thermal efficiency and a competitive cost advantage.
