Abstract

The pressure to reduce the emissions of the flue gas pollutants from iron ore sintering is enlarging increasingly. Based on the accumulation heat effect of sinter bed, the reasonable distribution of fuel in sinter bed was identified through the calculation of material balance and heat balance of raw materials. The sinter bed with a height of 300 mm was divided into three units, and the average available accumulation heat rate was about 38%. The reasonable coke powder addition ratio of each unit was 6.6%, 5.7%, and 5.2%, respectively, from the top to the bottom of sinter pot. The sinter-pot test results showed that the fuel consumption and the emissions of SO2, NOx, CO, and CO2 was reduced by 7.5 kg/t, 57.7%, 18.4%, 72.5%, and 31.7%, respectively, when compared with the conventional method in which the coke powder addition ratio of raw materials was 6.6%. Meanwhile, the sinter quality was improved.
