SUMMARY:Blast furnace operation practice with co-injection of natural gas and PCI
DESCRIPTION:Based on the result of theoretical analysis, it has been shown that injection of pulverized coal supports process conditions either to provide higher smelting rate or achieve minimum coke specific consumption. In case of coke and natural gas replacement, two conflicting factors can be observed: gas amount per minute is reduced thus having a favorable effect on gas dynamics both at upper and lower zones of the furnace; porosity is decreased in slag formation zone. It determines extreme correlation between PCI (pulverized coal injection) consumption and blast furnace performance. It has been established that increasing ratio of PCI to natural gas (NG) consumption is followed by lower coke and total carbon in fuel specific consumption at slowdown. High smelting rate can be achieved with this ratio within the range of 2.0-2.5.
