Coal Conversion Reactions and Their Impact on BF PCI Operations

摘要：

Pulverized coal injection is one of the most effective technologies to reduce blast furnace coke consumption. Thus, by significantly decreasing the coke requirement of the blast furnace, this technology in turn can considerably reduce the hot metal cost and decrease environmental problems related to the cokemaking process. The coal conversion process within the blast furnace is very complex, consisting of coal pyrolysis, combustion and gasification of char as well as assimilation of unburnt char by molten slag and hot metal. In this paper, the role of each stage of the coal conversion process is examined and the impact of each individual stage on smooth blast furnace operation is discussed.
