ANALYSIS OF THE BENEFITS OF BLAST FURNACE PRESSURE GAS RECOVERY
The energy consumption and pollutants produced in the blast furnace ironmaking process account for a large proportion of iron and steel enterprises,and ironmaking is the key process to achieve energy saving,carbon reduction and pollutant emission reduction.In the process of blast furnace smelting,the equalized pressure gas of the tank after distribution is directly discharged into the atmosphere,which will not only have a negative impact on the surrounding environment,especially the blast furnace production area,but also cause a waste of energy(blast furnace gas).The recovery of blast furnace tank equalization and release of gas can not only reduce CO2,CO and dust emissions,but also reduce energy loss,improve resource utilization,and achieve a win-win situation of environmental and economic benefits.Starting from the technical analysis of the natural recovery and full recovery process of blast furnace equalized gas in the blast furnace tank,combined with the actual production,through the statistics,accounting and analysis of the operation data and benefits of the blast furnace equalized gas recovery system under different working conditions,the technical characteristics of the blast furnace equalized pressure gas recovery were quantitatively explained,and the respective advantages of the two gas recovery technologies were evaluated.
