Abstract:
In this study, the general exergy balance equation of an open system is obtained based on the variable ambient temperature and pressure. Using this result, the mathematical equations regarding both the reversible work given to the system in the electric arc furnace used in steel production and the exergy loss in the rotary burner used in cement production are derived. In obtaining these equations, it is assumed that the ambient temperature has a sinusoidal variation. The effects of varying ambient parameters on calculated exergy values in industrial applications are discussed, and the obtained results are analyzed and demonstrated.
