Improvement in blast furnace performance top pressures above 15 psig are becoming more common and some furnaces are operating at top pressures as high as 30 psig. Day 8 gas cleaning plant main components of. Day 7 cast house blast furnace operation blast furnaces in vsp 8. Day 5 cast house introduction blast furnace structure principle components of the charge 6.

5 4 4 gas cleaning system gases generated during the reduction process in the blast furnace pass through the gas cleaning system. The primary function of the blast furnace gas cleaning system is to remove particulate matter from this gas. Blast furnace gas cleaning systems high efficiency gas cleaning systems are vital for the reliable operation and long campaign life of high temperature hot blast systems and steam generation facilities and allow the operators to meet the relevant pollution control standards. The recovered sludge dust contains relatively high quantities of iron and carbon and can thus be recycled through the sinter.

Furnace off gases firstly pass through a dust catcher to remove the large dust particles then through a gas scrubber and finally electrostatic precipitators to remove the fine particulates and other gas impurities. Day 4 stock house sending charge to the furnace screening 5. In addition the system also cools the gas to reduce its moisture content thus increasing its calorific value. Day 6 cast house stove house gas enrichment bell less top charging system 7.

Blast furnace gas it is the by product of blast furnaces that is generated when the iron ore is reduced with coke to produce molten iron. It is narrow at the top and has an arrangement for the introduction of ore and outlet for gases.
