[[Iron]] is a most fundamental metal used for athe lifeway of life for most human beingbeings, as it is rich inabundant, resourcewhich resultingresults in low priceprices, it can easily be extracted, and is easily modified due to its useful material property. After anthe [[industrial revolution]] (18-19th century), iron becomesbecame a core material of industrial market, its importance was referred to in the phrase “iron is nation”, its productivity was directly treated as its national power. Therefore after the [[World War 2]], governmentgovernments vigorously supported the growth of the iron industrial market; as a consequence, the action significantly contributed and influenced the development of the global economy. For theits various application uses, iron ore is extracted and [[smelt]]ed through athe usesuse of metallurgical furnace called a "[[Blast Furnace]]".
The Blast furnaceFurnace method is consideredexpected to survive for another century because of its highly efficient iron production rate at competitive costs with other iron making technologymethods. Blast furnace efficiencyfurnaces keep on improving by adapting with new technologicaltechnologies support which is stimulatedresulting from the accumulatedrising global demand, yet the main chemical process remains same. AlthoughBut improvement of process does not mean solving for the problemproblems associated in uses of blast furnace. The rate of Iron production rate is highly influenced fromby the world economicseconomy which varies over the time and improvementimproving ofthe operationoperations efficiency can be considered as one of major concerns fromfor usesusers of the blast furnace, however the biggest drawback of blast furnace operation is itsthe inevitable [[carbon dioxide]] production from iron reduction processes, which is considered asone of the major contributorcontributors in [[global warming]]. Nowadays, the Pulverized Coal Injection (PCI) method isan internationally popular method infor improving blast furnace operation.
