The typical features for an integrated iron & steelmaking industry are high energy consumption and CO2 emission.The traditional BF-BOF process in an integrated Iron and steelmaking enterprise produces a large amount of residual heat and energy,which has great potential for recovery and abatement potential of CO2 emissions.In this paper,for an integrated Iron & steelmaking enterprise of 10 million tons per year in capacity,the residual heat and energy recovery analysis was conducted.It is indicateded that the residual heat and energy can be recovered as electric power by using present advanced process technology.By means of the distributed power generation,the residual heat and energy can be recovered,with a power generation capacity of 419.5 kWh per ton steel product.Accordingly,the abatement potential of CO2 emissions for an integrated iron & steel making enterprise was also evaluated,which indicated that about 398.5 kg CO2 could be reduced per ton steel product.
