Energy and exergy analysis of a ladle furnace

In this work, the second law of thermodynamics is applied to the industrial ladle furnace (LF) with a capacity of 55-57 tons of melted steel to evaluate the physical exergy during the steel production process. A computer algorithm is developed to carry out the exergy analysis to the LF. The exergy efficiency of the ladle furnace is determined. As a result, loss exergy; exergies going into and out of the LF during the steel production process are identified and the ways of minimizing these losses in practice are discussed.
