Pulverized coal injection (PCI) 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.
Pulverized coal injection was developed in the 19th century, but was not implemented industrially until the 1970s. Rises in the cost of coke due to increased global demand and thus more competition for the resource have made this method attractive to the iron-producing industries and increased its value. The PCI method is based on the simple concept of primary air (termed the "conveying gas") carrying pulverized coal which injected through a lance to the tuyere(mid-bottom inlet of a blast furnace), then mi

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.

gas and coal injection levels were held at about 100 and 180 lb/THM respectively over this time frame, except for brief periods when the coal supply was lost. A maximum gas coinjection level of natural gas of about 125 lb/THM was reached when the coal injection level had been reduced to about 175 lb/THM. TEST SITE DESCRIPTION AND OPERATING
Burning the coal in the combustion process to release the energy in the fuel. Why Pulverizing ? The basic requirement of coal combustion is that all the carbon particles in coal should get sufficient air to burn and release the heat. Coal normally is available to power plants in large lumps ranging from 2 mm to 50 mm size.
