Energy and exergy analysis of BouyerSanat steel company

In this study, Exergy and energy analysis of processes of the steel production in Bouyersanat steel industry that contains three stages, melting in induction furnace, preheating and continuous casting is carried out. After doing exergy and energy balance of three stages separately, amount of energy transferred with different way and their shares, exergy losses for each stage and their shares and energy and exergy efficiency are calculated, and finally the overall process has been evaluated. By discussion of the results solutions among preheating of input materials to EIF, Increasing of amount of deoxidization materials like Coke and High carbon ferro manganese, and drafting a proper lid for preheating process are suggested.
