Evaluation of the energy efficiency of an aluminum melting furnace for a Nigerian cast-coiled plant

The energy efficiency of the aluminum melting furnace was evaluated for a Nigerian cast-coiled plant. The energy input was evaluated using the daily production data of the company while the energy output was determined through the second law of thermodynamics. The energy intensity for processing 876...
