Abstract: | The heat loss and its distribution are of great importance for the calculation and simulation of COREX process.Based on Baosteel COREX process,a method was applied to measure the heat loss of the furnace shell,the accessory equipments and the cooling water system.Then,a static model was established based on the measured heat loss of COREX process.The results showed that the main heat loss of furnace shells took place at the dome of the COREX melter-gasifier and the reducing gas entrance position of the shaft furnace while the main heat loss caused by cooling water occurred at the tap hole area.And the heat loss caused by cooling water accounts for about 85% of the total heat loss in COREX process.The measured total heat loss for producing every 1thot metal was 542.164 MJ,which accounted for about 92% of the theoretical total heat loss. |
