Coal injection into the blast furnaceThe IFRF pulverized fuel preparation plant includes a combined drying and pneumatic transport system for raw coal. The coal is pulverized in a ball mill and fed pneumatically into storage bunkers. From the storage bunkers the coal is delivered via a rotary valve into a pressu- rized, microprocessor controlled gravimetric.grinding mill in pulverized coal injection pdf,Impact of PCI Coal Quality on Blast Furnace . - Semantic ScholarPulverized coal injection has assisted the steel industry to lower operating costs, extend coke oven life and lower . used to investigate the impact of the injected coal ash content on the likely operating costs of a blast furnace. .
