Research on the Selection of Ultra-low Emission Process for Flue Gas from the Hot Blast Stove of Beiying Blast Furnace
The blast furnace hot blast stove is one of the main sources of flue gas pollutant emissions in the steel industry.By studying the latest emission requirements standards for blast furnace hot blast stove flue gas pollutants and combining them with the characteristics of the flue gas of the Beiying blast furnace hot blast stove,a technical route suitable for ultra-low emission of blast furnace hot blast stove flue gas is proposed.It is believed that the fixed bed dry desulfurization and denitrification integrated process technology has the characteristics of simple system composition,small footprint,small system temperature drop,wide applicable temperature range,and can directly enter the desulfurization system in high,medium and low temperature zones.It can provide reference for other steel enterprises in the selection of ultra-low emission transformation processes for hot blast stove flue gas.
