Control Blast Furnace Pulverized Coal Injection to

Pulverized coal injection (PCI) is a recognized method of controlling costs in iron making. The blast furnace is a complex system, so the replacement of coke with pulverized coal is not as simple as increasing the injection rates, especially when one considers iron chemistry, fuel rates and furnace campaign life. Important factors must be considered to achieve stable furnace operating conditions.
