Pulverized coal injection method Wikipedia

Apr 04, 2011 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

Injected coal is considerably cheaper than metallurgical coke and can replace coke on an almost 1:1 basis. Coke is more expensive. The limited availability of coke, as a result of environmental conditions, has forced it’s price to continually rise. Injected coal is more economical than other tuyere injectants, such as natural gas, oil, etc.
