Pulverized Coal Injection (PCI) systems of the original Sumitomo design, developed in 1981--1985, are now in successful operation on three blast furnaces at Sumitomo Metal Industries. Because mechanical coal feeders have limited capacity, however, multiple units would be required for high injection rates on large furnaces.Web
The coal is extracted out of a coal silo (1), supported by an aeration system (2). The rotor weighfeeder Pfister® DRW (4) doses the coal with high precision and the transport air (5) discharges the machine and blows the coal directly to the burner. The high feed accuracy of the rotor weighfeeder ensures a steady air/coal mixture for the burner.Web
