pulverized coal injection Reliable, efficient and accurate injection of auxiliary reducing agents is vital for cost effective blast furnace operation. Paul Wurth is involved in the development and application of all forms of gaseous, liquid and solid reducing agents injection via the hot blast tuyeres.
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 .
Also by producing less coke, more time would be available for repair and rebuilding of existing batteries. Coal injection started at Taranto blast furnaces Nos. 4, 2, 5 and 1 in September, October, November, 1991 and January, 1992 respectively. A central grinding and injection station supplies coal to the blast furnaces.
ROGESA was founded in 1981 and currently produces up to 4.6 million tons of hot metal each year.

Pulverizers: Williams Roller Mills pulverize or granulate and air classify chemicals, minerals, coal, limestone, phosphate rock, pigments, tobacco, clay, and barytes. Roller mills are also capable of drying with the addition of a heater. Williams Direct Fired Mills pulverize coal and petroleum coke fuel for direct firing into boilers and kilns.
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.
