Abstract:This paper expounds the importance of saving energy of ironmaking system in iron & steel industry, as well as the meaning of exergy analysis. Black box models of exergy analysis are established for pelletizing, sintering, coking and blast furnace process in ironmaking system, and the exergy efficiency and exergy loss are calculated. It reveals the exergy loss types and quantity as well as the effect of the recovery of waste heat and energy. It shows that the internal exergy loss of each process is much larger … Show more
