PERFORMANCE EVALUATION OF A GRATE COOLER IN A

The performance evaluation parameters considered were clinker temperature, cooler loss and efficiency. The exit clinker temperature was measured to be 56.620C. It is found that 23.90% of the total heat energy (383.51 Kcal/kg.cl) generated is being lost even though a big percentage of this heat (76.10%) was being recovered. The cooler efficiency was found to be (75.53%) at
