A comprehensive study on energy and exergy analyses for …
As the input feed to the system increases, a greater contribution of energy and exergy entering the system is spent on clinker formation, resulting in less energy and exergy being wasted from the system; thus, first and second law efficiencies increase. Although, the efficiency of the system improves by increasing the feed rate, the free lime ...
