Pulverized Coal Injection (PCI) using the dense-flow method. The Küttner developed and perfected dense-flow method offers several advantages over a lower-density system. Higher injection rates are achieved with simultaneously lower coke rates, which can optimize the fuel costs of the blast furnace. In addition, dense-flow technology enables jerk-free and pulsation-free conveyance over long distances, …
Pulverized Coal Injection
Pneumatic transfer of pulverized coal into the Dis- tribution Device as well as conveying of individual flows from the Distribution Device into the hot blast tuyeres are performed by means of pneumatic con- veying. Pneumatic conveying may be of • the dense phase type or • the dilute phase type.
Pulverized Coal Injection
Coal injection system. Reduced pollution Coal grinding and injection systems are non-polluting systems. Injecting pulverized coal into a blast furnace reduces the overall pollution made by coke production.

Pulverized Coal Injection (PCI) System for Blast …
Pulverized Coal Injection (PCI) System for Blast Furnaces. In the past, reactions within the blast furnace were stimulated by injecting heavy oil, as auxiliary fuel, along with the blasts and oxygen. The heavy oil was replaced by pulverized coal after the oil crisis. This made it possible to use cheap coal, such as non-coking coal. Furthermore, the amount of coke used can be reduced if huge amounts of …
