Pulverized coal injection has assisted the steel industry to lower operating costs, extend coke oven life and lower greenhouse emissions. As the understanding of the impact of quality of the injected coal has increased, there has been a shift from high volatile thermal coals to low volatile semianthracites. A heat and mass model was used to investigate the impact of the injected coal

Coal dried with air at 250–350°C for milling in low, medium or highspeed mills. Main milling costs are power and replacement of worn parts. Wear depends on fineness of grinding, and on hardness and abrasiveness of coal. Coal and air distribution to burners must be uniform to avoid local reducing zones which encourage slagging. Burners for

· Pulverized coal injection (PCI) coal; Hard coking coals like anthracite have better coking properties than semisoft coking coals, allowing them to garner a higher price. Australian HCC is regarded as the industry benchmark. While PCI coal is not often classified as coking coal, it still is used as a source of energy in the steelmaking process and can partially replace coke in some blast
